ATMEGA32A-AU Description

Short technical summary and product information.

The ATMEGA32A-AU is a low-power, high-performance 8-bit AVR microcontroller from Microchip Technology. It features 32KB of in-system self-programmable Flash memory, 2KB internal SRAM, and 1KB EEPROM with high endurance: 10,000 write/erase cycles for Flash and 100,000 for EEPROM. Data retention is rated at 20 years at 85°C and 100 years at 25°C.

 

This MCU operates at up to 16 MHz, delivering up to 16 MIPS throughput. It includes a rich set of peripherals: two 8-bit timers, one 16-bit timer, four PWM channels, an 8-channel 10-bit ADC, and multiple serial interfaces (I²C, SPI, UART/USART). Additional features include brown-out detection, power-on reset, and a watchdog timer.

 

The device is supplied in a 44-pin TQFP package (10x10 mm) and supports a supply voltage range of 2.7V to 5.5V. It operates over the industrial temperature range of -40°C to +85°C. The internal oscillator eliminates the need for external clock components in many applications.
