ATMEGA16U2-MU Description

Short technical summary and product information.

The ATMEGA16U2-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 16KB of in-system self-programmable Flash memory, 512B SRAM, and 512B EEPROM. The device is based on the advanced RISC architecture, delivering up to 16 MIPS throughput at 16 MHz.

This microcontroller includes a USB 2.0 full-speed device module with a dedicated 48 MHz PLL, supporting data transfer rates up to 12 Mbit/s. On-chip peripherals include two timers, SPI, USART with hardware flow control, programmable watchdog timer, analog comparator, and pin change interrupts. It also features brown-out detection, power-on reset, and an internal calibrated oscillator.

The ATMEGA16U2-MU is supplied in a 32-VFQFN exposed pad package (32-VQFN 5x5 mm) for surface mount assembly. It operates over a supply voltage range of 2.7V to 5.5V and an industrial temperature range of -40°C to 85°C. Flash endurance is rated at 10,000 write/erase cycles, and EEPROM at 100,000 cycles, with data retention up to 100 years at 25°C.
