ATMEGA32U2-AU Description

Short technical summary and product information.

The ATMEGA32U2-AU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 32KB of in-system self-programmable Flash memory, 1KB of SRAM, and 1KB of EEPROM with high endurance (10,000 Flash and 100,000 EEPROM write/erase cycles). The device operates at a maximum speed of 16 MHz, delivering up to 16 MIPS throughput.

 

This microcontroller includes a USB 2.0 full-speed device module compliant with USB Specification Rev 2.0, supporting data transfer rates of 12 Mbit/s. It offers 22 general-purpose I/O lines and connectivity options including SPI, USART with hardware flow control, and USB. On-chip peripherals include an 8-bit timer/counter with PWM, a 16-bit timer/counter with capture and PWM, a programmable watchdog timer, an analog comparator, and a debugWIRE interface for on-chip debugging.

 

The ATMEGA32U2-AU is supplied in a 32-TQFP (7x7 mm) surface-mount package with a gull wing lead style and 0.8 mm lead spacing. It operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to 85°C, making it suitable for a wide range of embedded control applications.
