16-Kbyte self-programming Flash Program Memory, 1-Kbyte SRAM, 512 Byte EEPROM, JTAG interface for on-chip-debug. Up to 16 MIPS throughput at 16 MHz. 1.8 - 5.5 Volt operation.
The ATmega162 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISCarchitecture. By executing powerful instructions in a single clock cycle, the ATmega162 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimizepower consumption versus processing speed.
