2.1 Overview
The STR730-EVAL board is a general purpose evaluation platform with CAN (controller
area network), and RS232 interfaces.
2.2 Processor
The board supports the STR730FZ2T7 ARM7TDMITM silicon - 144-pin TQFP version. This
chip runs at a frequency of up to 36 MHz.
Boot modes and configuration options are set using microswitches.
2.3 Debug
Software debug uses a standard 20-pin JTAG connection. This may connect to a standard
host to JTAG interface.
2.4 Prototype area
A 2.54 x 2.54 mm gridded area of 1mm holes is available for prototyping using wire wrap or
similar prototyping techniques.
2.5 Reset
The reset sources are:
●
power on reset,
●
push button reset,
●
JTAG reset from an in-circuit emulator.
2.6 Power supplies
Power to the board is supplied using a lump in cord power supply providing 5 V to the board.
All other required voltages are provided by on-board voltage regulators.
2.7 CAN interface
A general purpose, asynchronous serial I/O data port connected through a 9-pin D-type
male connector with microswitch selectable low speed fault tolerant transceiver (L9669) or
low or high speed selectable transceiver (L9616). See
Section 3.1: CAN bus connector on
page 14 .
The L9669 transceiver only works in normal mode, the wake-up functionality is not
implemented.
