The ATmega162 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It has 16K bytes of in-system self-programmable Flash, 512 bytes EEPROM, 1K bytes internal SRAM, 35 programmable I/O lines, and a JTAG interface.
The document describes the ATmega162 and ATmega162V, including pin configurations and pin descriptions, the block diagram, operating voltages and speed grades, and the ATmega161 compatibility mode selected by programming the M161C fuse. The ATmega162 is described as 100% pin compatible with the ATmega161.
