MICROCHIP ATTINY45-20SU 8 Bit MCU, Low Power High Performance, AVR ATtiny Family ATtiny45 Series Microcontrollers, AVR

The ATTINY45-20SU is a 8-bit low-power AVR RISC-based Microcontroller Unit combines 4kB ISP flash memory, 256-byte EEPROM, 256B SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, USI, internal and external interrupts, 4-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes and debug wire for on-chip debugging. The device achieves a throughput of 20MIPS at 20MHz. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed.
