Demokit overview
Demokit overview
The demokit tools for short-range RFID readers with Autonomous functions are designed to
demonstrate several STMicroelectronics products (see Section 6: References):
RFID Short Range, Turbo Plus Series and Serial Real-Time Clock products.
1.1
RFID Short Range products
These STMicroelectronics products include the CRX14 and CR14 readers, and several
contactless memories/tag products: SRI4K, SRIX4K, SRIX512.
All the contactless memories are powered by a transmitted carrier radio wave at 13.56MHz
and are compliant with the ISO 14443-B recommendation for the transfer of power and
signals via radio transmission. The Short Range CRX14 / CR14 RFID reader circuitry
amplitude modulates (10% modulation) the data on the carrier using amplitude shift keying
(ASK) and the tag replies by load modulating the data on the carrier using the BPSK (Bit
Phase Shift Keying) of a 847kHz subcarrier. The data transfer rate in each direction is 106
Kbit/second.
1.2
µPSD3422EV Turbo Plus Series product
The µPSD3422EV belongs to the popular µPSD family of 8051-class embedded Flash
microcontrollers that offers system-level-integration with world-leading Flash memory and
SRAM densities (up to 256-KBytes and 32-KBytes, respectively) for general-purpose 8-bit
embedded applications.
The µPSD3422EV Turbo Plus series performs up to 10 MIPS peak and provides full-speed
USB. A JTAG interface supports in-system programming and MCU core debug with highspeed instruction tracing capability, eliminating the need for a hardware In-Circuit Emulator
(ICE). Other peripherals include a 16-bit Programmable Counter Array (PCA), an 8-channel,
10-bit resolution analog-to-digital converter, SPI and IrDA interfaces, six PWM (pulse-width
modulated) channels, an I²C (Intelligent Interface Controller) master/slave bus controller,
two standard UARTs (Universal Asynchronous Receiver/Transmitter), supervisory functions
such as a watchdog timer and low-voltage detect, and up to 45 general-purpose I/O pins.
1.3
M41T65 (RTC) Serial Real-Time Clock product
The M41T65 (RTC) is used in a broad range of applications. It is available in a lead-free 16pin QFN package (just 3mm²) and is designed for a bus operating voltage from 3.6V down to
1.3V, but will maintain timekeeping at supply levels as low as 1.0V, thus providing more
robust system performance. Operating current is only 350µA on a 3.0V supply, making the
RTCs ideal for battery operation and handheld applications. M41T65 operates over the
industrial temperature range of –40 to +85° C.

Short-range reader
Short-range reader
The reader has two main modes of operation:
●
CRX14USB Demokit Mode
●
Autonomous Mode
In the CRX14USB Demokit Mode, the reader behaves exactly in the same way as in the
CRX14USB Demokit (see the UM0080 User manual) and is fully compatible with the
CRX14Demokit software.
In the Autonomous Mode, the PC can send a macro-command to the reader via the USB or
the RS232 cable, and the reader can then execute it without any further need of the PC.
There are two Autonomous Mode sub-functions: AutoRead and AutoWrite.
●
In the AutoRead cycle: after a “Start” (from either the push button or the PC), the
onboard reader reads the UID of whatever tag (STMicroelectronics Short Range family)
comes into the antenna field, and deals with the ASCII User Data (either read
(AutoRead) or write operations (AutoWrite)). Every event is logged as a record in the
Flash memory of the µPSD.
●
In the AutoWrite cycle: first the reader has to memorize the user phrase, then, after a
“Start” (from the push button or the PC), the reader always writes the same ASCII
phrase to the User Data area of whatever tag (STMicroelectronics Short Range family)
that comes into the antenna field. The rest of the User Data is filled with blanks.
Successful read and write operations are indicated by the flashing of Green LED 1. The
cycles have to be ended by a “Stop” (from either the push button or the PC). The only case
where a cycle will end automatically is when the Flash memory space is full (full FLASH
detected). Once the operation is stopped, the stored data can be downloaded to the PC
through a USB or UART macro-command. If the Autonomous reader cycle is stopped the
whole Flash memory record storage space can be erased via another macro-command.
Switching between the CRX14USB Demokit Mode and the Autonomous Mode can be done
either through a software command from the PC or by pressing and holding the onboard
button (SW1) for a few seconds.

Memory records
Autonomous Events are all being stored in the Flash memory space of the onboard
microcontroller. To minimize and simplify Flash memory management, a simple principle of
incremental write of records with fixed length (32 Bytes) is used. The structure of an event
record is described in Table 1.

Control board description
To use the Control board in Autonomous mode it is useful to get familiar with the onboard
diagnostic LEDs:
●
Green LED 1 (the green LED closer to the µPSD chip) lights up to indicate an activity
on the interface to the higher system, that is on the USB or RS232 ports.
●
The red LED shows communication activity on the I²C bus and can therefore be
interpreted simply as RF activity.
●
Green LED 2 informs about the operating status of the board. It will light up in a
continuous way in the CXR14USB Demokit mode and flash in the Autonomous mode.

Win32 Dashboard Control
The dashboard of the short-range RFID reader is divided into five panels: “Mode Switch”,
“Mode Control”, “RTC Control”, “Memory Records” and “Runtime Log”. They are shown in
Figure 9.
In the “Mode Switch” panel, located at the center of the window, the user can switch modes
(Switch Mode button) or check (Get Mode button) the current operating mode of the reader.
The “Mode Control” panel, on the left-hand side of the window, contains controls for
Autonomous cycle setup and supervision: Auto Read Mode button, Auto Write Mode button,
AutoWrite Mode Phrase edit box and Start / Stop button.
The panel also accommodates the Download All and Erase All buttons used for the
maintenance of the Event Records stored in the onboard memory.
The three software LEDs that mirror the real-time behavior of the reader are also on the
“Mode Control” panel.
The “RTC Control” panel, located below the “Mode Switch” panel, contains the controls
related to the reader’s Real Time Clock (RTC) chip: Set Time and Get Time buttons.
By pressing the Sync w PC button the user can easily synchronize the onboard reader’s
time with the local PC/Laptop time.
The “Memory Records” panel, located at the bottom of the window, stores the information
received from the reader after the Download All button has been pressed.
The “Runtime Log” panel, on the right-hand side of the window, simply traces all the activity
managed by the Win32 Dashboard.
