Need to program MC68HC908AS32ACFN - Desperately need help!

mikev — Wed, 25 Apr 2007 04:58:49 GMT

I have a bunch of MC68HC908AS32ACFN MCU's I need to program for a product line we have acquired. I'm very late on the project. This is new to me. I'm more of a programmer than an electrician. I have the latest Codewarrior for the HC08. I just need to get the code on the chips. I have a P&E 68HC08 MONO8 device, but thats only half the solution. I've tried to wire it to a chip socket... but not doing to well. Is there a 52-pin PLCC adapter that will accept the above MCU and a MONO8 header? Or a complete all-in-one board setup? Almost everything I see out there are for 64-pin QFP versions.

Thank you,

Mike

Hi Mike:

Would a programming adapter help?

Hello Mike,

According to the MON08 Multilink manual, the following connections to the MON08 16-pin header are required for programming the HC908AS -

Pin 2 = Gnd (Vss)

Pin 4 = Reset

Pin 6 = IRQ (Vtst)

Pin 10 = PTA0

Pin 12 = PTC0

Pin 13 = Osc1

Pin 14 = PTC1

Pin 15 = Vout (Vdd)

Pin 16 = PTC3

All other pins on the header are not connected.

You will need to identify the pins on the PLCC52 that correspond to these connections, and connect accordingly. I would use a through-hole type PLCC socket for more convenient point-to-point hand wiring.

I assume you need to program the devices separately, rather than in situ on the board.

Regards,

Mac
