Can I work the AVRUSB on Mage88PA

Post by Jack Yang » Thu Mar 05, 2009 6:00 am

Our project need to change the device number Mage88 to Mage88PA, but when recompiler the AVRUSB source code and reprogram to Mage88PA, the windows can't get the device VID and PID information, so can we use the AVRUSB on Mage88PA ?

I bet the electrical specs are different, there may be diffences in the registers/behavior too. Do you have a schematic to take a look at ? AVR GCC (and avr_libc) expects atmega88p as parameter for -mmcu..

AVR528: Migrating from ATmega48/88 and ATmega48P/88P to ATmega48PA/88PA (3 pages, revision C, updated 1/09)
The ATmega48PA/88PA is a functionally identical, drop-in replacement for the ATmega48P/88P. All devices are subject to the same qualification process and same set of production tests, but as the manufacturing process is not the same some electrical characteristics differ.

AVR512: Migration from ATmega48/88/168 to ATmega48P/88P/168P (5 pages, revision A, updated 07/06)
The ATmega48P/88P/168P is designed to be pin and functionality compatible with ATmega48/88/168, but because of improvements mentioned in this application note there may be a need for minor modifications in the application when migrating from ATmega48/88/168 to ATmega48P/88P/168P.
