ATMEGA128-16MU Description

Short technical summary and product information.

The ATMEGA128-16MU is an 8-bit AVR microcontroller from Microchip Technology based on the high-performance AVR RISC architecture. It delivers up to 16 MIPS throughput at 16 MHz, making it suitable for a wide range of embedded control applications.

 

The device features 128 KB of in-system self-programmable Flash memory, 4 KB SRAM, and 4 KB EEPROM. Peripherals include two 8-bit timers, two 16-bit timers, an 8-channel 10-bit ADC, PWM outputs, brown-out detection, and a watchdog timer. Connectivity options include I2C, SPI, dual USART, and an external bus interface.

 

The microcontroller operates from 4.5V to 5.5V and over a temperature range of -40°C to +85°C. It is housed in a 64-VFQFN exposed pad package (64-QFN, 9x9 mm) designed for surface-mount assembly, providing excellent thermal performance.
