概要
Description
ATxmega64A1U-CUR is Microchip’s USB-enabled AVR XMEGA microcontroller (A1U family). It uses the AVR XMEGA core, runs up to about 32 MHz, and provides:
- 64 KB of on‑chip Flash program memory; on‑chip RAM and EEPROM
- USB 2.0 Full‑Speed device interface (USB-capable)
- Rich peripheral set: multiple USARTs, SPI, I2C/TWI, 12‑bit ADC, timers with PWM, and various capture/compare modules
- Advanced features: Peripheral Event System for inter-peripheral signaling and DMA-like data transfers
- Power management with several sleep modes for low power
- Supported by Microchip Studio/Atmel Studio and GCC toolchains
The CUR suffix denotes a specific packaging type for this device. This MCU is well-suited for USB-connected embedded controls, data logging, sensor interfacing, and compact embedded systems requiring USB connectivity. For exact pinout, memory sizes, and peripherals, consult the ATxmega64A1U-CUR datasheet.
