[Diy_efi] phillips xag49 engine management

Perhaps you have time to look at an Atmel ATMega128. It has 8
timer-counters which can be used for PWM, etc.; is
in-system-programmable; has 127kbytes of program store; a fair
amount of EEPROM and can self-program new code. Incorporates two
USARTS. Supports all sorts of buzzwords and abbreviations I don't
understand yet, like JTAG debugging, etc.

It has "only" eight 10-bit ADC... but that may be enough for your
application.

More information from http://www.atmel.com or just get the
datasheet from http://www.atmel.com/atmel/acrobat/doc2467.pdf
