Before you order...
All of our standard connector options are available for this board. The product photo above shows "RA1" style connector on both H1 and H2. Please make your choice of connectors before adding this item to your shopping cart. Otherwise, the board will be shipped with the default option (no connectors on H1 and H2).

Product Details


Adapt9S12EQ128 is a compact, modular "AdaptS12" form factor board, compatible with an entire range of application cards, prototyping cards, and backplanes, and usable with solderless breadboards ("proto boards"). The Basic configuration includes all necessary support circuitry for the MCU, including a 5-Volt regulator, 8MHz crystal, reset button, BDM connector, and RS232C interface. This configuration features jumper-selectable RS232 or RS485 for the second SCI channel. Accommodation for a user-supplied precision voltage reference is also provided on-board.

Here are a few ways you can use Adapt9S12EQ128:

- 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 126K Flash via the serial port using our uBug12JE graphical user interface for Windows/Mac/Linux. The entire 126K Flash can be programmed in under 12 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 Flash Mode.

The Serial Monitor is also supported by Freescale's CodeWarrior Integrated Development Environment, for automatic erasing and loading of flash, and C source-level debugging.

- Flash-based code development using a BDM pod

If you want to take advantage of a more advanced development tool (such as our USBDMLT or UBDM12LX5), the entire 128K Flash can be used, because the Flash-resident bootloader is no longer needed (therefore pseudo-vectors aren't required either).
