The AT90USB646-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 64KB of in-system self-programmable Flash memory with 100,000 write/erase cycles, 4KB internal SRAM, and 2KB EEPROM with 100,000 write/erase cycles. The core operates at up to 16MHz, delivering 16 MIPS throughput. It includes a rich set of peripherals: Brown-out Detect/Reset, POR, PWM, and WDT. Connectivity options include EBI/EMI, I2C, SPI, UART/USART, and a full USB 2.0 Full-Speed/Low-Speed OTG interface with built-in 48MHz PLL. The device has 48 general-purpose I/O pins and an internal oscillator. It is supplied in a 64-VFQFN exposed pad package (9x9mm QFN) and supports a wide operating voltage range of 2.7V to 5.5V and temperature range of -40°C to 85°C. The on-chip JTAG interface supports debug and programming. This microcontroller is suitable for applications requiring USB host/device functionality, such as industrial control, embedded systems, and portable devices.
