ATMega32A PU MCU 8 BIT ATMEGA

The ATmega32A-PU is a high-performance 8-bit AVR microcontroller by Microchip, engineered for stability, flexibility, and ease of prototyping. Packaged in a DIP-40 through-hole form, it’s perfect for breadboarding, development boards, and standalone controller designs.

Built on RISC architecture, it integrates 32KB of Flash memory, 2KB SRAM, and 1KB EEPROM, allowing efficient handling of programs, runtime data, and non-volatile storage. With a maximum clock speed of 16 MHz, it provides responsive control for both simple and moderately complex applications.

The microcontroller includes 32 general-purpose I/O lines, 8-channel 10-bit ADC, 3 timers, and interfaces like USART, SPI, and I²C (TWI) — making it well-suited for sensor interfacing, communication modules, and real-time control systems.
