STEVAL-IFS009V1
extension for SN250 network processor
Introduction
This user manual describes the STEVAL-IFS009V1 ZigBee® extension hardware. It
includes a block diagram, schematics of the extension, and a bill of material and assembly
instructions.
The STEVAL-IFS009V1 operates in standalone mode. Alternatively it can be used as
a SN250 ZigBee interface with an application using an STR9 dongle.
The SN250 integrates a 2.4 GHz IEEE802.15.4-compliant transceiver with a 16-bit XAP2b
microprocessor. It features embedded Flash and RAM memories, as well as peripherals
useful to design ZigBee-based applications.
The extension board is supplied with a demonstration firmware loaded in the SN250 Flash
memory. The firmware source code is not provided by STMicroelectronics.
The STEVAL-IFS009V1 is delivered with a CD-ROM containing technical documentation.
This information is also available on ww.st.com/zigbee.

The main features of the extension board are the following:
●
●
●
SPZB250 radio communication module based on SN250 ZigBee network processor
LIS302DL Digital MEMS in LGA14 package (optional)
It can be accessed by the ZigBee network processor through an I2C bus.
STLM75 temperature sensor or compatible device in SO8 package (optional). It is
connected to the ZigBee network processor through an I2C bus.
●
Digital interfaces: one I2C and one SPI interface which can be used indifferently by the
SN250 ZigBee network processor to interface with the STR9 dongle
●
Supply voltage
The extension board can be supplied externally from the STR9 dongle or internally by
an on-board Ion-Li battery. The battery has a capacity of 65 mA hours which allows
approximately one hour of operation. It is charged through a mini USB connector. 2
LEDs can be used to monitor the charging:
–
Red LED: charge in progress
–
Green LED: charge completed
●
1 button connected to the SN250 ZigBee network processor WAKE_UP input
●
3 LEDs connected to the SN250 ZigBee network processor:
●
–

Connection of STR9 ZigBee extension to the STR9 dongle
This section provides additional information on how to connect the STR9 ZigBee extension
board to the STR9 dongle (see Figure 3).
●
●
●
I2C bus
–
The STR912, SN250, LIS302DL (MEMS), and STLM75 temperature sensor
communicate through the I2C bus. The SN250 is connected to the STR9 dongle
through SC1 I2C connector.
–
The master can be either the dongle STR912 (STR912FAW34, STR912FAW42
and STR912FAW44) or the SN250 ZigBee network processor.
SPI bus
–
The SPI bus is shared between the STR12 and SN250. The SN250 is connected
to the STR9 dongle through SC2 SPI connector.
–
The dongle STR912 is configured to operate as a master by connecting the input
SSP0_NSS of the SPI bus to V DDQ through the pull-up resistor R26.
–
The SC2_SEL input is used to select the ZigBee module. It is connected to P80
pin of the STR9 dongle.
Power supply
–
The board can be supplied directly by the STR9 dongle, please refer to
Section 1.5.3.
1.5
Board supply
1.5.1
Supply from battery
Board is typically supplied from battery. Li-Ion LIR2430 rechargable battery is
recommended. Capacity of 65 mAh gets to ZigBee board several hours of life. In the battery
operation mode SW1 is closed and SW2 is close on pins 3V3 and BAT. Have in mind there
is a protection against total battery discharge. When the battery voltage goes below 3.075 V
(typ.) the voltage supervisor activates the inhibit pin of voltage regulator.
1.5.2
Battery charging
Charging process starts automatically when USB (mini-USB) is connected. Let's remind
there are no data on the USB, it's used just for charging. SW2 must be close during
charging.
When charging red led LD12 is turned-on and green led LD11 turned-off.
When charged/done the green led LD11 turned-on and red led LD12 is turned-off.
7/10
Block diagram
UM0458
When error occurs, e.g. battery is missing, both leds red LD12 and green LD11 are turnedon.
It's good to keep SW1 open, to be able to charge the battery. It is possible to charge battery
even the SW1 is closed (board in operation mode) but the charging process starts again and
again.
1.5.3
Supply directly from pins
It's possible to charge the board directly from the pins of CN2. In this case the SW1 is
closing 3V3 and CON. pins. This connector is compatible with STR9_DONGLE (STEVALIFS0001V1). Please refer to UM0282.
1.6
Board storage recommendation
When not using the board for longer time, It's strongly recommended to remove or
disconnect (SW2 open) the battery from the board.
1.7
Measurements
1.7.1
Battery measurement
It is possible to use SW2 for measurement: battery voltage or current (closing by
ampermeter).
1.7.2
Output voltage measurement
It is possible to use SW1 to measure final voltage outcoming from the voltage regulator.
1.8
Firmware
Firmware is pre-flashed. For your own application development you need to have a tool.
STMicroelectronics offers: www.st.com/stonline/products/literature/bd/13503/sndev250.htm.
Note:
8/10
The demonstration firmware embedded in the SN250 Flash memory manages the
communications with the STML75 and the MEMS through the I2C interface. The user can
interact with the SN250 through its UART which is connected to CN2. SPI communications
are not supported. However the demonstration firmware can be modified and
reprogrammed into the Flash memory.
