Looking for Atmel AVR microcontrollers? We've got them! They're really, really good. Truly. And pretty inexpensive, too! Solarbotics has bags of them. Well protected, anti-static bags of them!

Description ^[Hide]

This ATtiny45V is an low voltage version of the ATtiny45 8-pin DIP IC with impressive capabilities!

Flash	EEPROM	SRAM	Speed	Volts
4kB	256B	256B	0 - 10MHz	1.8 - 5.5V

The AVR series of microcontrollers are right up there with Microchip PIC products. Powerful, inexpensive, and programmable with some very good open source software (look up GCC), with a vibrant user community.

4K Bytes of In-System Self-Programmable Flash
256 Bytes In-System Programmable EEPROM
256 Bytes Internal SRAM
Two 8-bit timer/counters with PWM and prescaler
10-bit ADC, USI-Universal Serial Interface
debugWIRE for on-chip-debug
Up to 20 MIPS throughput at 20 MHz
1.8 - 5.5 V operation.

For a small, low-voltage, single-purpose applications, it's a cheap and powerful solution! Hmmm... looks like it'd be happy running on solar power too!
