What you get:

  • this product ships with hardcopy data sheet and schematic diagram

Ease-of-Use Features:

  • supports programming in C, BASIC, Forth, assembler, etc.
  • 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 nqBASIC, CodeWarrior, or the free 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 MicroBDM12LX), 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.

Detailed features:

  • capable of 3-Volt operation (using Vin pin)
  • optional standard 6-pin BDM connector supports full debugging capabilities (with an optional BDM pod)
  • ECLK signal is user-accessible (via pad on circuit board)
  • access to eight 10-bit analog input or digital I/O port lines (Port AD)
  • access to eight digital I/O port lines (Port T)
  • up to five PWM timer channels (PT0 - PT4)
  • up to eight Input Capture/Output Compare pins (Port T)
  • internal programmable pullup and pulldown resistors on most pins
  • user access to MCU reset signal
