INTRODUCTION:

STM32-P152 is a development board with STM32L152VBT6 ARM Cortex M3 mi- crocontroller made by STMicroelectronics. This microcontroller supports various communication interfaces such as USB, three USARTs, two SPIs, two I2Cs. There are USB, JTAG and UEXT connectors, three buttons – WKUP, USER and RESET, four status LEDs, potentiometer and pin holes for most of the microcontroller’s pins. The board features low power segment LCD that uses the built in LCD controller in this specialized microcontroller. Due to its low power capabilities the board can run bat-tery powered applications via the battery connector. All this allows you to build dif-ferent projects for a wide range of applications.

ELECTROSTATIC WARNING:

The STM32-P152 board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.

BOARD USE REQUIREMENTS:

• Cables: The cable you will need depends on the programmer/debugger you use. If you use ARM-JTAG-EW, ARM-USB-TINY or ARM-USB-TINY-H, you will need USB A-B cable, if you use ARM-USB-OCD or ARM-USB-OCD-H, you will need USB A-B cable and RS232 cable.
• Hardware: Programmer/Debugger ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-TINY, ARM-USB-TINY-H, ARM-JTAG-COOCOX or other compatible programming/debugging tool if you work with EW-ARM. It is a good practice to first consider the software tools you are going to use and check if they support the debuggers.
• It is good idea to use SWD interface for debugging/programming because of the multiplexing of the JTAG signal lines with the display lines. If using a debugger that supports only JTAG layout you might need to disable display or write a routine that disables it.

POWER SUPPLY CIRCUIT:

STM32-P152 can take power from:

• PWR_JACK (5-6) VDC
• USB – +5V_USB.
• JTAG – +5V_JTAG.
• TRACE – +5V_J-TRACE
• Battery connector – +3.7V lithium battery.
• Pin Hole VIN – (5÷6) VDC.

The programmed board power consumption is about 50 mA with all peripherals enabled. The minimal current consumption is a few uA(up to 10)
Note that if the battery is connected to 3,7V-Li BAT connector and some of other power sources(USB, JTAG, TRACE, PWR_JACK) are present and the battery is discharged then the battery will be charge until the charge complete.

RESET CIRCUIT:
STM32-P152 reset circuit includes R8 (10k), R44 (330Ω), R11 (100Ω/1%), C28 (100nF), STM32L152VBT6 pin 14 (NRST) and RESET button.

CLOCK CIRCUIT:
Quartz crystal (Q1) 8 MHz is connected to STM32L152VBT6 pin 12 (OSC_IN/PH0) and pin 13 (OSC_OUT/PH1).

EXTERNAL CONNECTORS DESCRIPTION:

UEXT:

USB:

3.7V-LI_BAT:

JTAG/SWD:

Important: The default demo software blocks the JTAG communication. A workaround is to press and hold button B2, then press RST, then release B2. This will shut down the display allowing you to erase the demo via JTAG and after that the JTAG should be available.
SWD debuggers/programmers would not have such a problem.
