Overview
NanoCore12DXTM is a low-cost platform that brings the advanced features of the 9S12C microcontroller family within easy reach of engineers, students, and hobbyists. The flexible design accommodates all facets of training, evaluation, development, prototyping-- and even volume production.
While there are several DIP-format MCU modules on the market, none of them comes close to the power and value of NanoCore12! Others are based on RISC processors-- some relying on serial program memory, and have limited or no hardware subsystems on-chip. NanoCore12 is the only complete family of DIP modules based on a high-speed CISC device. Since RISC processors only possess primitive instructions, their high speed is necessary, in order to produce acceptable computing power. With a CISC processor running at the same speed, the overall performance is vastly improved-- and performance improvement is in orders of magnitude for certain types of operations. The S12 instruction set includes powerful DSP-like instructions, 16-bit arithmetic, and the architecture implements memory-to-memory moves, and many powerful addressing modes.

- 24 MHz bus speed (via PLL)
- local 5 Volt low-dropout 100 mA regulator
- includes RS232 transceiver circuit
- has on-chip Serial Monitor
- supports standalone operation
- 32K Bytes Flash
- 2K Bytes Ram
- 32-pin DIP form-factor
- gold-plated 0.025" square pins
- pinout is super-set of competing 24-pin modules on the market
- functionally equivalent to Freescale part #M68MOD912C32
Ease-of-Use Features:
- supports programming in C, BASIC, Forth, assembler, etc.
- no special Flash programming voltage or switch required
- fast in-circuit programming
- small footprint on-chip bootloader/monitor and free uBug12 GUI for quick loading/debugging of user programs
- Run/Load switch for choice of Standalone or Monitor operation following reset
- compatible with virtually all 9S12 development tools on the market
Flash-based code development using on-chip debug/monitor
With a 2K Flash-resident debug/monitor program, you'll be able to load your program into the remaining 30K Flash via the serial port using the CodeWarrior or uBug12 user interface for Windows. The entire 30K Flash can be programmed in about 3 seconds! To use the monitor for debugging or code-loading, just set the switch to LOAD. To run your standalone program thereafter, leave the switch at RUN. Your code runs from Flash, and interrupts are supported (via Flash-based pseudo vectors, since the monitor resides in the vector space of the MCU). A program you load into Flash this way will run every time you apply power or reset the board in Run Mode.
Flash-based code development using a BDM pod
If you want to take advantage of a more advanced development tool (such as MicroBDM12LX5 or USBDMLT), the entire 32K Flash can be used, because the Flash-resident bootloader is no longer needed (therefore pseudo-vectors aren't required either). You'll also need to use this method if you are using a non-Windows development platform.
