Overview

The M68EVB912B32 evaluation board (EVB) is an economical tool for designing and debugging code for and evaluating the operation of the MC68HC912B32 MCU. By providing the essential MCU timing and input/output (I/O) circuitry, the EVB simplifies user evaluation of prototype hardware and software.

The EVB features a prototype area, which allows custom interfacing with the MCU¡¯s I/O and bus lines. These connections are broken out via on-board headers immediately adjacent to the MCU.

Features

? +4.5 to +5.5 Vdc operation

? RS-232C interface

? 32 Kbytes of MCU internal FLASH EEPROM with resident D-Bug12 monitor/debugger program

? Four operational modes:

¨C EVB

¨C Jump-to-EEPROM

¨C BDM pod (background debug mode)

¨C Bootload

? Header connectors for access to the MCU¡¯s I/O and bus lines

? On-board prototype area for customized interfacing with the MCU

? Low-voltage inhibit protection

? Full support for either dumb terminal or host computer terminal interface

? IASM12 assembly language development toolkit

? File transfer capability from a host computer, allowing off-board code generation
