Little Micro Makes Big Flash

Atmel's latest 8-bit ATmega AVR microcontrollers are designed for large, low-power applications. The smallest part is the 64-pin ATmega 2561. The AVR's 32 register file is great for C programming. The chip also can wake up interrupts on up to 32 pins. Development kit and tools pricing starts at $79. Pricing for the ATmega starts at $4.75.
