ATMEL ATMEGA128-16AU 8-Bit AVR Microcontroller, 128KB Flash, 16MHz, TQFP64

The ATMEL ATMEGA128-16AU is a high-performance, low-power 8-bit AVR RISC-based microcontroller. It combines a substantial 128KB of program memory with 4KB of EEPROM and 4KB of RAM, providing ample space for complex firmware and data storage. An integrated 8-channel 10-bit A/D converter allows for precise analogue signal measurement, while the JTAG interface (IEEE 1149.1 compliant) facilitates powerful on-chip debugging and programming.

This device excels in efficiency, executing instructions in a single clock cycle to achieve throughputs approaching 1 MIPS per MHz. It supports a maximum throughput of 16 MIPS at 16MHz, effectively balancing processing speed with controlled power consumption. Operating from a 4.5V to 5.5V supply, it is designed for robust performance across a wide temperature range from -40°C to 85°C.
