The ATMEGA324A-AU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features an advanced RISC architecture with 131 instructions, most executed in a single clock cycle, achieving up to 20 MIPS throughput at 20MHz. The device integrates 32KB of in-system self-programmable Flash memory, 2KB SRAM, and 1KB EEPROM, with high endurance: 10,000 Flash write/erase cycles and 100,000 EEPROM cycles. Data retention is rated at 20 years at 85°C and 100 years at 25°C.
Key peripherals include two 8-bit timers, one 16-bit timer, 6 PWM channels, an 8-channel 10-bit ADC, and multiple serial interfaces (I²C, SPI, UART/USART). The microcontroller also features brown-out detection, power-on reset, and a watchdog timer. It operates from a supply voltage of 1.8V to 5.5V and over a temperature range of -40°C to 85°C.
Housed in a 44-TQFP (10x10mm) surface-mount package, the ATMEGA324A-AU is suitable for a wide range of embedded control applications, including industrial automation, sensor interfaces, and consumer electronics. The internal oscillator eliminates the need for external clock components, simplifying design.
The operating voltage range is 1.8V to 5.5V.
It comes in a 44-TQFP (10x10mm) surface mount package.
The operating temperature range is -40°C to 85°C.
It is listed as RoHS3 Compliant, but this is unverified and low confidence.
The maximum clock speed is 20MHz.
It has 32KB of Flash memory.
It has 32 general-purpose I/O lines.
