The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 4KB ISP flash memory, 256B SRAM, 12 general purpose I/O lines, 16 general purpose working registers, an 8-bit timer/counter with two PWM channels, a 8/16-bit timer/counter, internal and external interrupts, an 8-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, a slave two-wire interface, a master/slave serial peripheral interface, an internal calibrated oscillator, and four software selectable power saving modes. The device operates between 1.8-5.5 volts.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
