M68EVB912B32 Evaluation Board
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.
Figure 1 shows the EVB’s layout and locations of the major components as
viewed from the component side of the board.
