INTRODUCTION:

STM32-LCD is development prototype board with STM32F103ZE micro-

controller from STMicroelectronics. This powerful microcontroller supports various

serial interfaces such as USB, USART, SPI. In addition you will find also accelero-

meter, JTAG, TFT LCD, mini SD/MMC card connector on this board and most of

the GPIOs are on extension headers where you can connect your additional

circuits. All this allows you to build a diversity of powerful applications to be used

in a wide range of situations.

ELECTROSTATIC WARNING:

The STM32-LCD 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, you will need USB A-B cable.

Hardware: Programmer/Debugger ARM-JTAG-EW or other compatible

programming/debugging tool if you work with EW-ARM.

You can use also ARM-USB-OCD, ARM-USB-TINY, ARM-JTAG. or other

compatible programming/debugging tool.

BOARD LAYOUT

POWER SUPPLY CIRCUIT:

STM32-LCD can take power from four sources:

–Power connector – 4V – 6V DC.

–BAT_PWR from EXT_PWR – 4V DC.

–+5V_J-LINK from JTAG connector

–+5V_USB from USB connector

The programmed board power consumption is about 200 mA.

RESET CIRCUIT:

STM32-LCD reset circuit includes R8 (10k), R69 (560 Ohm), C28 (100nF)

pin 15 of JTAG connector, EXT pin 32, UEXT40 pin 32 and STM32F103ZE pin 25

(NRST).

CLOCK CIRCUIT:

Quartz crystal 8 MHz is connected to STM32F103ZE pin 23 (OSC_IN) and

pin 24 (OSC_OUT).

Quartz crystal 32.768 kHz is connected to STM32F103ZE pin 8

(PC14/OSC32_IN) and pin 9 (PC15/OSC32_OUT).

JTAG:

The JTAG connector allows the software debugger to talk via a JTAG (Joint Test Action

Group) port directly to the core. Instructions may be inserted and executed by the core thus allowing

STM32F103ZE memory to be programmed with code and executed step by step by the host software.

SPI

Up to three SPIs are able to communicate up to 18 Mbits/s in slave and

master modes in full-duplex and simplex communication modes. The 3-bit prescaler

gives 8 master mode frequencies and the frame is configurable to 8 bits or 16 bits.

The hardware CRC generation/verification supports basic SD Card/MMC modes.

All SPIs can be served by the DMA controller.

I 2

Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available,

that can be operated in master or slave mode. These interfaces can be configured to

operate with 16/32 bit resolution, as input or output channels. Audio sampling

frequencies from 8 kHz up to 48 kHz are supported. When either or both of the I2S

interfaces is/are configured in master mode, the master clock can be output to the

external DAC/CODEC at 256 times the sampling frequency.

I 2

Up to two I²C bus interfaces can operate in multimaster and slave modes.

They can support standard and fast modes.

They support 7/10-bit addressing mode and 7-bit dual addressing mode (as

slave). A hardware CRC generation/verification is embedded.

They can be served by DMA and they support SMBus 2.0/PMBus.
