The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 64KB ISP flash memory, 4KB SRAM, 2KB EEPROM, 53 programmable I/O lines, an 8-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging. The device achieves throughput of 16 MIPS at 16MHz and operates between 2.7-5.5 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.
