Are any of you currently using the MC9S12H128 or MC9S12H256 micros?

Are any of you currently using the MC9S12H128 or MC9S12H256 micros?

The 9S12H includes an LCD driver. This provides enough advantages for me to redesign my 68HC812A4 product to reduce my overall part count & PCB size.

I am interested in your personal experiences (opinions) with the 9S12H series and any target PCB's available that would help me to jump-start my product development.

Thanks,

Jerome,

I have designed an ICE for the 9S12H256 and have experience with the H256.
I am also familiar with the H256 LCD driver from the analog PRU (Port
Replacement Unit) for the LCD function of this emulator. The H family LCD
Driver can drive up to 128 LCD segments arrange in up to 32 Front-Planes *
4 Back-Planes, and the VLCD can be adjusted to fine-tune the LCD contrast.

If you have the budget, the H256 full-ICE ban be a significant jump-start
for your development:
For example you can use the ICE in stand-alone mode to develop code and try
it with an LCD, before you have a target board laid-out. Once you have a
target board, you can connect it to the ICE, and continue your development
with all the added benefits of a full ICE over a BDM (Execution and bus
activity recording in a Trace. Ability to test and debug Resets, Power-Down
modes, Clock-Loss Limp-Home mode, and full use of the internal H256 PLL,
including frequent speed changes).

Hope this helps,
