ATMEGA324P-20AU Description

Short technical summary and product information.

The ATMEGA324P-20AU is a low-power, high-performance 8-bit AVR microcontroller based on the enhanced RISC architecture. It features 32KB of in-system self-programmable Flash, 1KB EEPROM, and 2KB internal SRAM. With a maximum throughput of 20 MIPS at 20MHz, it is suitable for a wide range of embedded applications. The device includes peripherals such as two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and multiple serial interfaces (I²C, SPI, USART). It operates from 2.7V to 5.5V and over a temperature range of -40°C to 85°C. The microcontroller is available in a 44-pin TQFP package (10x10mm) for surface mount assembly. It also features JTAG interface for debugging and programming.
