Microchip Technology ATtiny102/104 AVR 8-Bit Microcontrollers

Microchip ATtiny102/104 AVR 8-Bit Microcontrollers are based on the AVR® enhanced RISC architecture. Throughputs close to 1MIPS per MHz are achieved by executing powerful instructions in a single clock cycle. This allows device optimization for power consumption versus processing speed. The high-performance, low-power ATtiny102, and ATtiny104 MCUs have 1024Bytes of in-system programmable flash memory with 32Bytes of internal SRAM.
