ATMEGA323L-4AC Description

Short technical summary and product information.

The ATMEGA323L-4AC is an 8-bit microcontroller from Microchip Technology based on the AVR core architecture. It features 32KB of in-system self-programmable Flash memory, 2KB of internal SRAM, and 1KB of EEPROM. The device operates at a maximum speed of 4MHz and supports a supply voltage range of 2.7V to 5.5V.

 

This microcontroller includes a rich set of peripherals such as two 8-bit timer/counters, one 16-bit timer/counter, four PWM channels, an 8-channel 10-bit ADC, and multiple serial communication interfaces including I2C, SPI, and USART. Additional integrated features include brown-out detection, power-on reset, and a watchdog timer.

 

The ATMEGA323L-4AC is designed for embedded control applications requiring efficient processing and low power consumption. It is packaged in a 44-lead TQFP (10x10mm) surface-mount package, making it suitable for space-constrained designs. The internal oscillator simplifies clock generation, reducing external component count.
