INTRODUCTION:
STM32-P152 is a development board with STM32L152VBT6 ARM Cortex M3 microcontroller 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 battery powered applications via the battery connector. All this allows you to build different 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, ARMUSB-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.

SCHEMATIC:
BOARD LAYOUT:
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).
Quartz crystal (Q2) 32.768 kHz is connected to STM32L152VBT6 pin 8
(PC14/OSC32_IN) and pin 9 (PC15/OSC32_OUT).
JUMPER DESCRIPTION:
R-T
When this jumper is closed, RST and TRST/SEG8 are connected. When this jumper is
opened, RST and TRST/SEG8 are separated.
Default state is opened.
SHUNT_E
When this jumper is closed, 1 Ohm shunt is enabled. When this jumper is opened, 1
Ohm shunt is disabled.
Default state is closed.
GNDA_E
When this jumper is closed, the board analog ground is enabled. When this jumper is
opened, the board analog ground is disabled.
Default state is closed.
3.3VA_MCU_E
When this jumper is closed, the microcontroller analog power is enabled. When this
jumper is opened, the microcontroller analog power is not enabled.
Default state is closed.
3.3V_MCU_E
When this jumper is closed, STM32L152VBT6 power supply is enabled. When this
jumper is opened, STM32L152VBT6 power supply is disabled.
Default state is closed.
PWR_LED_E
When this jumper is closed, the PWR_LED is enabled. When this jumper is opened,
the PWR_LED is disabled.
Default state is closed.
B0_1/B0_0
This jumper, when is in position B0_1 – connects STM32L152VBT6 pin 94 (BOOT0) via
R15 (10k) to 3.3V, when the jumper is in position B0_0 – connects STM32L152VBT6
pin 94 (BOOT0) via R15 (10k) to GND.
Default state is closed in position B0_0.
Page 10
B1_1/B1_0
This jumper, when is in position B1_1 – connects STM32L152VBT6 pin 37
(PB2/BOOT1) via R7 (10k) to 3.3V, when the jumper is in position B1_0 – connects
STM32L152VBT6 pin 37 (PB2/BOOT1) via R7 (10k) to GND.
Default state is closed in position B1_0.
The boot mode is selected depending on jumpers B0_1/B0_0 and B1_1/B1_0
configuration:
- When B0_1/B0_0 is closed in position B0_0 and B1_1/B1_0 position doesn't matter the boot mode is Main Flash Memory.
- When B0_1/B0_0 is closed in position B0_1 and B1_1/B1_0 is closed in position B1_0
– the boot mode is System Memory.
- When B0_1/B0_0 is closed in position B0_1 and B1_1/B1_0 is closed in position B1_1
– the boot mode is Embedded SRAM.
INPUT/OUTPUT:
Status led (green), with name STAT1 is connected to STM32L152VBT6 pin 29
(PA4/DAC_OUT1), allowing current through it to be adjusted smoothly.
Status led (yellow), with name STAT2 is connected to STM32L152VBT6 pin 30
(PA5/DAC_OUT2), allowing current through it to be adjusted smoothly.
Status led (red), with name STAT3 is connected to STM32L152VBT6 pin 41 (PE10).
Status led (green), with name STAT4 is connected to STM32L152VBT6 pin 42
(PE11).
Power-on led, with name PWR_LED – this led shows that the board is power
supplied.
User button with name WKUP is connected to STM32L152VBT6 pin 23
(PA0/WKUP1).
User button with name USER is connected to STM32L152VBT6 pin 7
(PC13/WKUP2).
User button with name RESET is connected to STM32L152VBT6 pin 14 (NRST).
Trimmer with name AN_TR is connected to STM32L152VBT6 pin 82
(PD1/SPI2_SCK) – signal “TRIMER_EN”.

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.
