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.
- based on the 9S12C32 MCU (48-pin LQFP version)
- includes 8 Mhz crystal
- 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
- 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 on a Windows platform
- 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 our 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.
