Adapt9S12D is a compact, modular implementation of Freescale's 9S12D family of microcontroller chips. The HCS12 family is backward-compatible with 68HC12 (and 68HC11), and utilizes the latest 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 CAN configuration includes all necessary support circuitry for the MCU, as well as a 5-Volt regulator, RS232, and two CAN transceivers on-board.


MCU Overview:

The MC9S12DP512 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 512K bytes of Flash EEPROM, 14K bytes of RAM, 4K bytes of EEPROM, 2 asynchronous serial communications interfaces (SCI), three serial peripheral interfaces (SPI), an 8 channel IC/OC enhanced capture timer, two 8-channel, 10-bit analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), 89 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital I/O lines with interrupt and wakeup capability, five CAN 2.0 A, B software compatible modules (MSCAN12), J1850 (BDLC), and an Inter-IC Bus.

Module Features:

  • surface-mounted 112-pin 9S12DP512 MCU
  • 2.30" x 3.25" AdaptS12 form-factor
  • two 50-pin connectors bring out all I/O pins of the MCU
  • all I/O pins on a 0.1" grid for easy interfacing to standard perfboard
  • versatile connector options for use with solderless breadboards, prototyping cards, or embedding into your design
  • RS232C transceivers provided for both SCI channels
  • support for two physical-layer high-speed CAN transceivers (PCA82C250)
  • 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 (BDM pod required)
  • 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 (D-Bug12) for quick loading of user programs
  • ideal development platform for all "D-" and "A-" series 9S12 variants (eg. 'DT, 'DP, 'DG, 'A, etc.)
  • 100mA, automotive grade, low-dropout 5V regulator on-board (mounted underneath)
  • includes low-voltage inhibit (LVI) reset circuit + reset button
  • accommodates optional precision voltage reference chip for analog-to-digital converters
  • accommodates optional BOOT/RUN switch to support Serial Monitor option
  • second I/O connector accommodates memory expansion bus option

Product Details

- Flash-based code development using a BDM pod

Use a BDM pod (such as MicroBDM12LX) to erase and load Flash with your program. The entire 512K Flash can be used for your program. Just use the FBULK and FLOAD commands to erase and load your programs.

- Low-cost Solution for C source-level code debugging with ICC12, NoICE12, and a MicroBDM12LX pod

Now you can take advantage of the debug/monitor functions of NoICE12 to perform source-level debugging with ImageCraft's ICC12 C compilers, using our MicroBDM12LX. This combination offers one of the lowest-cost toolchains on the market!
