Hey look, an Atmel chip! Amazing! Well, it is a nice improvement on the popular ATtiny45 in that it now offers 8kB of programmable Flash.

Description [Hide]

Here's what the geniuses at AVRFreaks have to say about it!

This is a nice upgrade to the very popular ATtiny45 microcontroller, bringing up the Flash to 8kB! The ATtiny85 features: 8K Bytes of In-System Self-Programmable Flash, 512 Bytes In-System Programmable EEPROM, 512 Bytes Internal SRAM. Two 8-bit timer/counters with PWM and prescaler, 10-bit ADC, I2C Interface and debugWIRE for on-chip-debug. Up to 20 MIPS throughput at 20 MHz. 2.7 - 5.5 V operation. Also available in 1.8 V version (ATtiny85V). Smaller Flash versions available -> 4KB version: ATtiny45 2KB version: ATtiny25
