The Microchip Technology ATMEGA128A-AUR is an 8-bit AVR RISC microcontroller featuring 131KB of FLASH program memory and 16KB of SRAM. Operating at up to 20MHz, this CMOS device supports a wide supply voltage range from 5.0V to 5.5V, with reduced frequency operation at lower voltages (10MHz at 2.7V minimum, 4MHz at 1.8V minimum). Connectivity options include dual USARTs, I2C, and SPI interfaces. It integrates 32 general-purpose I/O lines, 8 channels of 10-bit Analog-to-Digital converters, and multiple peripherals such as a watchdog timer, brown-out detection, and 8 PWM channels. The ATMEGA128A-AUR is housed in a 44-pin TQFP package and finds application in industrial automation, consumer electronics, and IoT devices. Boundary scan is supported.
