ATMEGA16-16AU 8-Bit AVR MCU, 16KB Flash, 16MHz, TQFP44

The ATMEGA16-16AU from Atmel is a high-performance, low-power 8-bit microcontroller based on the advanced AVR RISC architecture. It combines 16KB of in-system programmable flash memory, 1KB of SRAM, and 512 bytes of EEPROM, making it a versatile choice for embedded control applications. With a throughput of 16 MIPS at 16MHz, it executes powerful instructions in a single clock cycle, achieving near 1 MIPS per MHz for an optimal balance of processing speed and power efficiency.

The device operates on a 4.5V to 5.5V supply and features a rich peripheral set, including an 8-channel 10-bit A/D converter, two 8-bit timer/counters, and one 16-bit timer/counter. For development and debugging, it includes a full JTAG (IEEE 1149.1 compliant) interface. Its 32 general-purpose working registers are all directly connected to the Arithmetic Logic Unit (ALU), enabling highly efficient code execution.
