ATXMEGA64A1-AU Description

Short technical summary and product information.

The ATXMEGA64A1-AU is an 8/16-bit microcontroller based on the AVR XMEGA core from Microchip Technology. It offers 64 KB of in-system self-programmable Flash memory,4 KB SRAM, and 2 KB EE PROM. With 78 prog rammable I/O pins, the device inclu des a rich set of peripherals: four-channel DMA controller, eight-channel event system, eight 16-bit timer/count ers (with high-resolution and advanced waveform extension), eight USARTs, four SPI interf aces, four I2C interf aces, AES and DES crypto eng ine, a 16-bit RTC, two 16-channel 12-bit ADC s, two 2-channel 12-bit DAC s, and four analog compar ators. It operates from 1.6 V to 3.6 V and can run at up to 32 MHz (with 2.7-3.6 V supply) or up to 12 MHz (with 1.6-2.7 V supply). The device is housed in a 100-lead TQFP package with a 14x14 mm body. The operating temperature range is -40°C to +85°C. This microcontroller is suitable for a wide range of embedded applications requiring high performance, low power, and extensive integration. Note: The datasheet indicates this part is not recommended for new designs; the XMEGA A1U series is suggested as a replacement.
