Ok...

This is what I'm looking for.
 2k EEPROM (for program) FLASH or EEPROM
min 64 bytes RAM
Min 64 bytes data EEPROM
  What I need to know is what AVr corresponds with this and how many I/O pins does it have.
Last time I looked AVR mention I/O PORTS rather than pins, so unless there is a number of pins to a port.....

I'm young and adaptable.... I can go with Atmel just as easily as PIC at this point Provided I know where to start.


TIA

I have very recently been told by an overseas Mchip 
salesman that Mchip "can compete with any OTP micro 
out there". Let's see...

after 2k ROM, 128 bytes RAM, and 128 bytes EEPROM?

The 90S2333 AVR has just that, along with :

* 118 Powerful Instructions - Most Single Cycle Execution
* 32 x 8 General Purpose Working Registers
* Up to 8 MIPS Throughput at 8 MHz
- Compare, Capture Modes and 8-, 9- or 10-bit PWM
* On-chip Analog Comparator
* Programmable UART
* 6-channel, 10-bit ADC
* Master/Slave SPI Serial Interface
* Active: 3.4 mA

...and the AVR's cost half that of the PICs (except the 
12CXXX OTP's that are about 40% cheaper than the Flash 
Tiny AVR's)

Good morning, Steve.
