I've used the 912D60A for years. It's time to move up to something better - and that appears to be something like the S12D64 or the S12E64. [All I really...

... E64 doesn't have CAN module; so you probably want A64, not D64. A64 is cheaper twin of D64, just without MSCAN. Are you using on chip EEPROM? If not, or if...
... No need for CAN on this, or an SCI. Do need an SPI. I am going to be hooking to a USB, but it looks like a separate USB module may be the best solution...

Hi James, That layout in the datasheet is a "best practice" layout. Trying to make the best of all worlds (ATD, Crystal, PLL, etc.)and fit it all onto a single...
... Thanks for the advice. Looks like the S12A will work. I had originally rejected it because the usual suppliers didn't have any. [Digikey only had the D...

Hello All, I am using the 9s12DG256. After I have successfully programmed Flash using a bootloader I try to read some of the memory locations. They do not...
