1.5.2

LEDs

4 general purpose LEDs are available as display devices.

1.5.3

Joystick

4-direction joystick with selection key.

1.6

Interfaces

1.6.1

CAN

The STR910-EVAL evaluation board supports CAN2.0A/B compliant CAN bus

communication based on a 3.3V CAN transceiver. Both High-speed mode and slope control

mode are available and can be selected by setting a dedicated jumper.

1.6.2

Ethernet

The STR910-EVAL supports IEEE-802.3-2002 compliant Ethernet communication via the

MII interface PHY transceiver (STE100P) with PHY address 10101b and an integrated RJ45

connector with embedded transformer.

1.6.3

RS232

The STR91x evaluation board (STR910-EVAL) provides three on-board RS232 serial ports.

Two channels, UART1 and UART2, use one RS232 transceiver U14.

UART0 uses the RS232 transceiver U13 with full modem control support.

All these RS232 ports are terminated by three male DB9 connectors.

1.6.4

Infrared data access (IrDA)

An on-board IrDA transceiver is available on U9 and the UART1 channel can be configured

to support IrDA communications.
