2.1

Overview

The STR720-EVAL board is a general purpose evaluation platform with ATAPI, USB, CAN

(controller area network) and RS232 interfaces.

2.2

Processor

a frequency of 66 MHz.

Boot modes and configuration options are set using microswitches, see

Section 2.15: Option

switch settings on page 12

2.3

Debug

Software debug is performed using a standard 20-pin JTAG connection. This may connect to a

JTAG in-circuit emulator.

2.4

Prototype area

A 2.54x2.54mm 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.
