AT90USB647-AU

The AT90USB647-AU is a high-performance 8-bit AVR microcontroller from Microchip Technology, featuring a RISC architecture with 135 instructions, most executing in a single clock cycle. It achieves up to 16 MIPS throughput at 16MHz. The device includes 64KB of self-programmable flash memory with 100,000 write/erase cycles, 4KB of SRAM, and 2KB of EEPROM. It also integrates a USB 2.0 full-speed/low-speed device and On-The-Go (OTG) module, supporting data rates up to 12 Mbit/s, with 832 bytes of dedicated DPRAM for endpoint memory. The microcontroller offers 48 programmable I/O lines, an 8-channel 10-bit ADC, and peripherals such as brown-out detect, power-on reset, PWM, and watchdog timer. It operates from 2.7V to 5.5V and over a temperature range of -40°C to 85°C. The device is housed in a 64-TQFP (14x14mm) surface-mount package, suitable for compact PCB designs. Typical applications include USB-enabled embedded systems, industrial control, and portable devices requiring low power and high performance.
