Integrated Module with the following features:

• Credit card sized (86mm x 54mm)
• Fitted with either the Motorola MC9S12D64, MC9S12DP512 or MC9S12XDP512 HCS12 Microcontroller (TQFP package - soldered to PCB)
• Up to 80 binary General Purpose Inputs/Outputs lines are brought out to two double row 0.1" headers
• 16 MHz Quartz Clock (8 MHz System Clock)
• Two RS232 Ports with Transceiver MAX232A
• PCA82C250 CAN Physical Interface
• Special Reset Controller
• Reset Switch
• Operating Mode selectable via jumpers
• BDM (Background Debug Mode) connector
• 5V power supply on-board

The difference between the Card.S12D64, Card.S12DP512 and CARD.S12XDP5 Controller Modules is simply the microcontroller which is fitted to the card. Each microcontroller has different amounts of on-board FLASH / EEPROM and also has different peripherals.

CardS12.D64
- Freescale MC9S12D64 microcontroller
- Features: 64 KB Flash, 1 KB EEPROM, 4 KB RAM, 1 x SPI, 2x SCI

CardS12.DP512
- Freescale  MC9S12DP512 microcontroller
- Features: 512KB Flash, 4KB EEPROM, 14KB RAM, 3x SPI, 5x CAN

The CardS12 Modules are shipped with a special version of the TwinPEEKS HCS12 Monitor Program. This allows easy programming and erasing of the microcontroller's internal Flash Memory. It is possible to quickly download code without the need of additional tools - no difference between RAM, EEPROM or Flash!

The Monitor Program resides in the write-protected Boot Block area of the Flash Memory and can therefore not be erased unintentionally. The Monitor Program on each CardS12  is ready-to-use - you do not have to prepare anything. Just switch it on and type in commands!  The TwinPEEKs Source Code is also available if required (seperate chargeable option).

The BDM Interface Port is a special port designed for uploading / debugging the on-chip code of the target HCS12 microcontroller. BDM stands for 'Background Debug Mode' which allows the operation of the HCS12 microcontroller to be controlled / monitored from an external program or emulator.

The CardS12 Modules feature a special BDM Port connector in the form of a 10-way IDC header. The module is supplied with a special cable which interfaces the BD port to the RS-232 port of a PC.
