Adapt9S12D is a compact, modular implementation of the NXP 9S12D series microcontroller. The HCS12 family is backward-compatible with 68HC12 (and 68HC11), and utilizes newer process technology. By shrinking feature size, more functionality can be put on a chip, reducing power consumption and cost, while increasing operating speed. Adapt9S12D is an ideal low-cost platform that brings these advantages within easy reach of engineers, students, and hobbyists. The flexible design of the entire Adapt series microcontroller products accommodates all facets of training, evaluation, development, prototyping, and even volume production.

Implemented in an AdaptS12 form factor board, Adapt9S12D is compatible with an entire range of application cards, prototyping cards, and backplanes, and usable with solderless breadboards (proto boards). The Minimal configuration includes all necessary support circuitry for the MCU, as well as a 5-Volt regulator and RS232 transceiver on-board.

Module Features:

• 2.30-inch x 3.25-inch AdaptS12 form-factor
• two 50-pin connectors bring out all I/O pins of the MCU
• all I/O pins on a 0.1-inch grid for easy interfacing to standard perfboard
• versatile connector design for use with solderless breadboards, prototyping cards, or embedding into your design
• RS232 transceivers provided for both SCI channels
• 16 MHz crystal, but internal bus can run up to 24MHz (using on-chip PLL)
• accommodates optional user-supplied oscillator
• Background Debug Mode (BDM) fully supported for loading and debugging user code
• universal 6-pin/10-pin BDM connectors support BDM pods from multiple vendors
• program in C, BASIC, Forth, assembler, etc.
• no special Flash programming voltage or switch required
• fast in-circuit programming
• on-chip bootloader/monitor (DBug12) for quick loading of user programs
• ideal development platform for all D- and A- series 9S12 variants (eg. 9S12DG, 9S12DA, etc.)
• automotive grade, low-dropout 5V regulator on-board (mounted underneath)
• includes low-voltage inhibit reset circuit + reset button
• accommodates optional precision voltage reference chip for analog-to-digital converters
• accommodates optional LOAD/RUN switch for alternative bootloaders
• second I/O connector accommodates memory expansion bus
