Hi, i am looking for a micro basically for data acquistion. I need two 8 bit pulse accumulators, 3 a2d channels and 128 KB of Non Volatile Memory ( preferably EEPROM). The code size will too small.(say 2KB) i was thinking of using a PIC micro with SPI to connect with an external EEPROM. Let me know if there are any micros for such applications. ( I basically want to do away with external memory) Thanks, Vishal.
right micro for data acq

I think they are a bit pricey for the job my solution will be a pic18f1320 or similar ( it have a 10 bit adc with multiplexer ) and 2 24xx512 i2c eeprom as storage ( you can connect up to 256KB of storage )
