ATMEGA64L-8AU Description

Short technical summary and product information.

The Microchip Technology ATMEGA64L-8AU is an 8-bit AVR microcontroller based on the AVR enhanced RISC architecture. It offers 64KB of in-system reprogrammable flash memory, 4KB internal SRAM, and 2KB EEPROM. The device operates at a maximum clock frequency of 8MHz and supports a supply voltage range of 2.7V to 5.5V.

 

Key peripheral features include two 8-bit timer/counters, two expanded 16-bit timer/counters with PWM, an 8-channel 10-bit ADC, and a programmable watchdog timer. Communication interfaces include I2C, SPI, and dual USARTs. The microcontroller also integrates a brown-out detection reset, power-on reset, and an internal calibrated RC oscillator.

 

The ATMEGA64L-8AU is housed in a 64-TQFP surface mount package with 53 general-purpose I/O lines. It is designed for industrial temperature range operation from -40°C to 85°C. The device is suitable for embedded control applications requiring moderate memory and versatile peripherals.
