Overview
The IDB-HC08JL Evaluation Board demonstrates the capabilities of the
28-pin MC68HC908JL devices. The IDB-HC08JL Evaluation Board can
be used as a standalone application or with an emulator system, such as
inDART-HC08, through a MON08-compatible connection.
Board Features
The IDB-HC08JL Evaluation Board has the following hardware features:
1. An MC68HC908JL3 microcontroller (in DIP28 package, already
programmed with a demo application—in addition, you can also use
any of the MC68HC908JL family devices);
2. ZIF socket for the microcontroller;
3. A standard MON08 connector;
4. Eight jumpers to connect/disconnect each of the eight LEDs to/from
their respective Port D pins;
5. Eight high-efficiency (low-current) LEDs connected to Port D;
