Interfaces

1.8.1

RS232

The STM32F100ZET6 evaluation board (STM32100E-EVAL) provides two on-board RS232
serial ports. Both RS232 ports are accessed via DB9 connectors.
1.9

Motor control

The STM32100E-EVAL evaluation board supports inductor motor control via a 34-pin
connector. This connector provides all required control and feedback signals to and from the
motor power-driving board.
1.10

IrDA

The STM32100E-EVAL evaluation board supports IrDA communication. The interface is
mounted on UART4.
1.11

Miscellaneous peripherals

1.11.1

Joystick

The board features a four-direction joystick with a selection key.
1.11.2

Push-buttons

The following push-buttons are available:
●
Key
● Tamper
●
Wakeup: used to wake up the processor from low power mode
1.11.3

12-bit analog-to-digital converter (ADC)

The MCU ADC channel (
variable resistor provides a voltage in the range of 0 V to 3.3 V.
Moreover, a BNC connector is available for analog input.
1.11.4

Audio amplifier

The STM32100E-EVAL evaluation board implements a dedicated audio amplifier which can
be interfaced with the STM32 DAC peripheral. For the audio output, a speaker and an audio
jack connector are available on the board and connected to the DAC.
1.11.5

Storage memories

The STM32100E-EVAL evaluation board features an 8 Mbyte SPI Flash memory and an
SD Card™ memory connected to the SPI2 peripheral. It features also an 64 Kbyte I
EEPROM memory connected to I2C2.
