Microchip Technology, Inc. 16-bit 16BIT 16KB Embedded Microcontroller MCU ATXMEGA16A4U-CU

The ATXMEGA16A4U-CU is an 8/16-bit microcontroller from the Microchip AVR XMEGA family, designed for low power and high performance applications. It features 16KB of in-system self-programmable flash memory, 4KB of EEPROM, and 2KB of internal SRAM. The device operates at a voltage range of 1.6V to 3.6V and can achieve clock speeds up to 32MHz. This microcontroller includes a variety of peripheral features such as a four-channel DMA controller, an eight-channel event system, and five 16-bit timer/counters with advanced waveform generation capabilities. It also supports USB 2.0 connectivity with 32 configurable endpoints, multiple USARTs, I2C, SPI interfaces, and has built-in cryptographic capabilities with AES and DES engines. The ATXMEGA16A4U-CU is equipped with a 12-bit, 12-channel ADC and a two-channel DAC, making it suitable for applications requiring analog signal processing. Additionally, it supports capacitive touch sensing through the QTouch library and includes a programmable watchdog timer and various sleep modes for power management. The device is available in a 49-ball VFBGA package, making it suitable for compact designs.
