Card12

The Red Card

Card12 is a credit card sized controller module with the MC912D60A (optional: MC912DG128A). The 'D60A is a member of Freescale's (formerly: Motorola's) HC12 Microcontroller family. The technical features are amazing (see details on the right!). Most appealing: The 60KB On-Chip Flash Memory and the integrated CAN-Bus Interface.

Two RS232 ports and a BDM interface are available on both our well-known HC812A4-based HC12 Welcome Kit and our new Card12 controller module. The Background Debug Mode Interface of the 'D60A additionally supports Hardware Breakpoints. Debugging using a cost-effective BDM-Pod (for instance ComPOD12) becomes so easy - even with code running in Flash Memory!

TwinPEEKs Monitor Program

Each Card12 controller module is equipped with a special version of our TwinPEEKs monitor software, which allows easy download and programming of Flash and EEPROM Memory - without needing additional hardware tools!

The monitor code resides in a write-protected Flash boot block (only 4KB). It can not be erased unintentionally.

The assembly language source code of TwinPEEKs is available on request (cost option).

Card12.DG128A

Card12.DG128A is yet another credit card sized HC12 Controller Module. Actually, it is based on the same PCB but equipped with a different MCU. The MC912D60A got replaced by an MC912DG128A, which provides the following enhancements:

• Two independent CAN interfaces
• 128 KB Flash Memory
• 2 KB EEPROM
• 8 KB RAM
• I2C-Bus Interface

In-System Programming/Debugging

Card12 is equipped with a standard 6-pin BDM interface for in-system programming and debugging.

The Background Debug Mode (BDM) of the HC12 MCUs provides a convenient way for debugging and in-system programming. We are offering a complete range of cost-effective HC12 development tools, including ComPOD12/StarProg, NoICE12 Remote Debugger and ICC12 ANSI-C Compiler.
