Low Power Wireless Sensor Module
Power
Tmote Sky is powered by two AA batteries. The module was designed to fit the two AA battery
form factor. AA cells may be used in the operating range of 2.1 to 3.6V DC, however the
voltage must be at least 2.7V when programming the microcontroller flash or external flash.
If the Tmote Sky module is plugged into the USB port for programming or communication, it will
receive power from the host computer. The mote operating voltage when attached to USB is
3V. If Tmote will always be attached to a USB port, no battery pack is necessary.
The 16-pin expansion connector (described in the Section on page 17) can provide power to the
module. Any of the battery terminal connections may also provide power to the module. At no
point should the input voltage exceed 3.6V—doing so may damage the microcontroller, radio, or
other components.

Low Power Wireless Sensor Module
Microprocessor
Description
The low power operation of the Tmote Sky module is due to the ultra low power Texas
Instruments MSP430 F1611 microcontroller featuring 10kB of RAM, 48kB of flash, and 128B of
information storage. This 16-bit RISC processor features extremely low active and sleep
current consumption that permits Tmote to run for years on a single pair of AA batteries. The
MSP430 has an internal digitally controlled oscillator (DCO) that may operate up to 8MHz. The
DCO may be turned on from sleep mode in 6μs, however 292ns is typical at room temperature.
When the DCO is off, the MSP430 operates off an eternal 32768Hz watch crystal. Although the
DCO frequency changes with voltage and temperature, it may be calibrated by using the 32kHz
oscillator.
In addition to the DCO, the MSP430 has 8 external ADC ports and 8 internal ADC ports. The
ADC internal ports may be used to read the internal thermistor or monitor the battery voltage.
A variety of peripherals are available including SPI, UART, digital I/O ports, Watchdog timer,
and Timers with capture and compare functionality. The F1611 also includes a 2-port 12-bit
DAC module, Supply Voltage Supervisor, and 3-port DMA controller.
The features of the MSP430 F1611 are presented in detail in the Texas Instruments
MSP430x1xx Family User’s Guide available at http://ti.com/msp430.

PC Communication
Tmote Sky uses a USB controller from FTDI to communicate with the host computer. In order
to communicate with the mote, the FTDI drivers must be installed on the host. FTDI provides
drivers for Windows, Linux, BSD, Macintosh, and Windows CE. These drivers are included on
the Moteiv CD shipped with your order. Windows users will need the Virtual Com Port (VCP)
drivers. They may also be downloaded from FTDI’s website at: http://www.ftdichip.com/
Tmote Sky appears as a COM port in Windows’ device manager (or as a device in /dev in
Linux, OSX, and BSD). Multiple Tmote Sky motes may be connected to a single computer’s
USB ports at the same time. Each mote will receive a different COM port identifier. In the
example below, one Tmote Sky is connected and assigned COM6 “USB Serial Port”.
An application may read from Tmote Sky by opening the COM port assigned to the Tmote Sky
module. Tmote communicates with the host PC through USART1 on the TI MSP430.

Moteiv tmote sky
NOTE: Tmote Sky uses an I2C digital switch to prevent unwanted conventional serial port
signals from reaching the TI microcontroller. The I2C protocol must be implemented and
sent over the RTS and DTR lines in order to obtain direct access between Tmote Sky and
the USB controller. The UART lines do not use the I2C switch allowing direct
communication (but not programming or JTAG) without additional software.
Programming
The Tmote Sky module is programmed through the onboard USB connector. A modified
version of the MSP430 Bootstrap Loader, msp430-bsl, programs the microcontroller’s flash.
Tmote Sky has a unique hardware circuit that prevents spurious resets. This hardware circuit
makes it necessary for a special sequence to be sent to the module in order to program it.
By invoking msp430-bsl, verify you have the patched BSL by looking for the “telos” keyword.
Version 1.39-telos-7 or later is required for Tmote Sky.

Low Power Wireless Sensor Module
To communicate with Tmote Sky, the MSP430 Bootstrap Loader requires a set of options to
provide the proper signals to the microcontroller to initiate programming. For convenience, the
options have been folded into a single Tmote flag:
--tmote
To program a Tmote Sky module on COM6 (or /dev/ttyUSB5 in Linux) with an application
image named app.ihex, invoke the MSP430 Bootstrap loader with the following options.

If you are using TinyOS, it has support for programming Tmote Sky. After compiling your
application, you may install it with the following command
> make tmote install,x bsl,n
Where x is the 16-bit address assigned to the mote and n is the COM port that Tmote Sky is
currently using. Note that not including “bsl” or “bsl,n” will program automatically using the
bsl to the first Tmote Sky mote found on the USB bus using the motelist command.
For more information about the options in the MSP430 Bootstrap loader, invoke msp430-bsl
with the -h option to display the help information.
motelist and msp430-bsl are available from Moteiv Corporation at http://www.moteiv.com in
the “Support” section.
NOTE: msp430-bsl starts counting from 0, but COM ports in Windows start counting at 1.
If Tmote is connected to COM6 in Windows, you must program it using “-c 5” or “bsl,5”
when invoking msp430-bsl. In Linux, Tmote Sky will appear as /dev/ttyUSB5 and may
be programmed using “-c 5” or “bsl,5”.

Radio
Description
Tmote Sky features the Chipcon CC2420 radio for wireless communications. The CC2420 is an
IEEE 802.15.4 compliant radio providing the PHY and some MAC functions. With sensitivity
exceeding the IEEE 802.15.4 specification and low power operation, the CC2420 provides
reliable wireless communication. The CC2420 is highly configurable for many applications with
the default radio settings providing IEEE 802.15.4 compliance. Features and usage of the
CC2420 is available in Chipcon’s datasheet at http://www.chipcon.com
The CC2420 is controlled by the TI MSP430 microcontroller through the SPI port and a series of
digital I/O lines and interrupts (see the Schematics on page 7 for more information). The radio
may be shut off by the microcontroller for low power duty cycled operation.
The CC2420 has programmable output power. Common CC2420 register values and their
corresponding current consumption and output power are shown in Figure 7.

The CC2420 provides a digital received signal strength indicator (RSSI) that may be read any
time. Additionally, on each packet reception, the CC2420 samples the first eight chips,
calculates the error rate, and produces a link quality indication (LQI) value with each received
packet. A mapping from RSSI to the RF level in dBm is shown in Figure 8.

Antenna
Tmote Sky’s internal antenna is an Inverted-F microstrip design protruding from the end of the
board away from the battery pack. The Inverted-F antenna is a wire monopole where the top
section is folded down to be parallel with the ground plane. Although not a perfect
omnidirectional pattern, the antenna may attain 50-meter range indoors and upwards of 125meter range outdoors. Measurements of the internal antenna’s performance with and without a
battery pack are show in Figure 10 and Figure 11. Approximate radiation patterns for the
Inverted-F antenna as provided by Chipcon AS are shown in Figure 12 and Figure 13.

External Flash
Tmote Sky uses the ST M25P80 40MHz serial code flash for external data and code storage.
The flash holds 1024kB of data and is decomposed into 16 segments, each 64kB in size. The
flash shares SPI communication lines with the CC2420 transceiver. Care must be taken when
reading or writing to flash such that it is interleaved with radio communication, typically
implemented as a software arbitration protocol for the SPI bus on the microcontroller.

NOTE: The ST M25P-series of code flash always starts in the standby state. For low
power applications, the flash must be sent a command at boot time to place it in the deep
power down mode. If using TinyOS, the flash is automatically put into deep power down
mode and must be instructed to exit deep power down mode the first time the flash is
accessed. See the ST M25P80 datasheet for more information.

Flash Hardware Write Protection
The flash includes hardware write protection functionality. The write protection exists on a
sector basis as shown in Figure 16. The hardware write protection pin (Pin 3 of the M25P80
shown in Figure 14) only disables write protection when the module is powered by the USB port.
When connected to USB, the status register must be updated by removing the write protect and
block protect bits in Figure 15. The write protected segments may only be changed after the
module connected to USB and the write protect bit is cleared.
Tmote Sky ships with sector 15 (the upper sixteenth sector) write protected and the SRWD bit
set. In sector 15 is the “Golden Image” and factor metadata. The “Golden Image” is a factory
program image that includes network reprogramming so that Tmote Sky may always return to a
known good state, even if loaded with a malfunctioning program image. When Tmote Sky is
connected to the USB, the “Golden Image” may be changed. See the TinyOS Deluge
documentation in tinyos-1.x/docs of the TinyOS distribution included with Tmote.

Sensors
Humidity/Temperature Sensor
The optional humidity/temperature sensor is manufactured by Sensirion AG. The SHT11 and
SHT15 models may be directly mounted on the Tmote module in the U3 component position.
The SHT11/SHT15 sensors are calibrated and produce a digital output. The calibration
coefficients are stored in the sensor’s onboard EEPROM. The difference between the SHT11
and SHT15 model is that the SHT15 produces higher accuracy readings as shown in Figure 18.
The sensor is produced using a CMOS process and is coupled with a 14-bit A/D converter. The
low power relative humidity sensor is small in size and may be used for a variety of
environmental monitoring applications.

Light Sensors
A variety of light sensors may be used with Tmote Sky. Tmote Sky has connections for two
photodiodes. Moteiv currently uses photodiodes from Hamamatsu Corporation
(http://www.hamamatsu.com)
If your mote is populated with light photodiodes, the default diodes are the S1087 for sensing
photosynthetically active radiation and the S1087-01 for sensing the entire visible spectrum
including infrared
Although these photodiodes from Hamamatsu have been tested with Tmote Sky, any
photodiode with similar physical dimensions may be used with Tmote Sky.

Expansion Connector
Tmote Sky has two expansion connectors and a pair of onboard jumpers that may configured so
that additional devices (analog sensors, LCD displays, and digital peripherals) may be
controlled by the Tmote Sky module. On the far side of the board from the USB connector is a
10-pin IDC header at position U2 and a 6-pin IDC header at U28. The 10-pin connector has the
same connections as Tmote Sky and is the primary connector. It provides digital input and
output signals as well as and analog inputs. Peripherals may be connected to the 10-pin
connector using an IDC header, an IDC ribbon cable, or by designing a printed circuit board that
solders directly on to the IDC header providing a robust connection to the module. An additional
6-pin (U28) header provides access to the exclusive features of Tmote Sky. Two additional
ADC inputs are provided that may be reconfigured by software to be two 12-bit DAC outputs.
ADC7 may also act as the input to the supply voltage supervisor. The user interface
elements—the reset and user buttons—are exported by the 6-pin header for use in external
interfaces and packaging.

Low Power Wireless Sensor Module
If expansion pin 10 (ADC3) is used to generate microcontroller interrupts instead of digital I/O
and analog input functionality, R14 must be populated with a 0 ohm resistor to enable the pin
for digital I/O (GIO0) on the microcontroller. R16 must be populated with a 0 ohm resistor to
enable GIO1. R14 and R16 are located on the top side of Tmote Sky between the USB
controller and the radio.
NOTE: When R14/R16 is populated (GIO0/GIO1 enabled), ADC3/ADC2 will not provide
reliable readings if an application reverts to using the ADC input instead of the digital I/O
port input on the microcontroller. R14/R16 are not required for digital I/O functionality from
ADC3/ADC2; they are only needed if an interrupt request must be generated by an
external device on these pins. R14/R16 should be removed when using ADC3/ADC2 for
analog input.
The 6-pin IDC header also has an optional jumper, R15. By installing a 0 ohm resistor at R15,
GIO3 is directly connected to SVSout. By making GIO3 an input and using the SVS features of
the microcontroller, the SVSout function can be exported via pin 4 of U28.
A separate Supply Voltage Supervisor (SVS) 2-pin IDC header is provided underneath the USB
connector at position U7. The SVS header allows add-on boards to be built that connect to the
positive and negative battery terminals and the SVS pins in order to provide power the module
and use the microcontroller’s advanced SVS functionality for boost converters, solar systems,
and rechargeable systems. The SVS header is shown in Figure 22 and includes the SVSin and
SVSout pins from the microcontroller.

Internal Temperature and Voltage Monitoring
The MSP430 microcontroller has internal temperature and voltage sensors that may be used
through the microcontroller’s ADC interface.
The voltage port (input 11) on the 12-bit ADC monitors the output from a voltage divider.

The temperature input is a temperature diode connected to internal ADC port 10. When using
the temperature sensor, the sample period must be greater than 30 µs. The temperature sensor
offset error can be large, and may need to be calibrated for most applications. The typical
response of the temperature sensor is shown in Figure 23.
