Product Details

Description:

Adapt9S12E128 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. A fully-populated configuration also includes RS485 and IrDA transceivers and a dual op amp for buffering the on-chip DACs, for audio applications. Accomodation for a user-supplied precision voltage reference is also provided on-board.

Here are a few ways you can use Adapt9S12E128:

- 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 uBug12 user interface for Windows. 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.

- Flash-based code development using a BDM pod

If you want to take advantage of a more advanced development tool (such as MicroBDM12SX), the entire 128K Flash can be used, because the Flash-resident bootloader is no longer needed (therefore pseudo-vectors aren't required either). Use of a BDM pod will also enable you to load and run code from an optional external RAM card, supporting unlimited software breakpoints.
