ATMEL ATMEGA162 8-Bit Microcontroller, 16K Flash, TQFP44

The ATMEL ATMEGA162-16AU is an 8-bit, high-performance, low-power AVR RISC-based microcontroller, designed for efficient and reliable embedded system control. It combines 16 KB of in-system programmable flash memory, 1 KB of SRAM, and 512 bytes of EEPROM, providing ample non-volatile and volatile storage for complex applications. A key feature is the integrated JTAG interface, which allows for advanced on-chip debugging and programming, streamlining the development process.

This device delivers a throughput of up to 16 MIPS at a 16 MHz clock speed, achieved through its advanced RISC architecture that executes powerful instructions in a single clock cycle. Operating from a wide voltage range of 2.7V to 5.5V, it offers excellent flexibility for both battery-powered and mains-operated designs. The core integrates 32 general-purpose working registers directly connected to the Arithmetic Logic Unit (ALU), enabling high-speed data processing and code that is significantly more efficient than traditional CISC microcontrollers.
