ATXMEGA128D3-MH Description

Short technical summary and product information.

The Microchip ATXMEGA128D3-MH is an 8/16-bit AVR XMEGA microcontroller designed for low-power embedded applications. It features a high-performance AVR core operating at up to 32 MHz with a supply voltage range of 1.6V to 3.6V. The device integrates 128KB of Flash memory, 8KB of SRAM, and 2KB of EEPROM for data storage.

 

Peripherals include a 16-channel 12-bit ADC, 18 PWM channels, five 16-bit timer/counters, and multiple serial communication interfaces: I2C (2 channels), SPI (5 channels), UART (3 channels), and IrDA. Additional features such as brown-out detection, power-on reset, and a watchdog timer enhance system reliability.

 

The microcontroller is packaged in a 64-VFQFN exposed pad (64-QFN 9x9mm) for surface mount assembly. It operates over an industrial temperature range of -40°C to 85°C and is RoHS3 compliant.
