ATMEGA128A-MUR Description

Short technical summary and product information.

The ATMEGA128A-MUR is an 8-bit AVR microcontroller based on the enhanced RISC architecture, achieving up to 16 MIPS throughput at 16MHz. It features 128KB of in-system self-programmable Flash memory, 4KB SRAM, and 4KB EEPROM. The device includes 53 general-purpose I/O lines, with connectivity options such as EBI/EMI, I2C, SPI, and UART/USART. Peripherals include brown-out detection, power-on reset, PWM channels, and a watchdog timer. An 8-channel 10-bit analog-to-digital converter is integrated. The operating voltage range is 2.7V to 5.5V, and the temperature range is -40°C to 85°C. The microcontroller is housed in a 64-VFQFN exposed pad package, with a supplier package of 64-QFN (9x9mm), suitable for surface-mount assembly. This device is ideal for embedded control applications requiring moderate processing power, rich peripheral integration, and low power consumption.
