Known for its PIC and AVR microcontroller families (including the ATmega series), the company serves industries like automotive, industrial, consumer electronics, and IoT.
The ATMEGA64L-8AU is an 8-bit AVR microcontroller with low-power (L) operation, 64KB Flash, and an 8MHz clock speed.

Application

The ATmega64L-8AU is an 8-bit microcontroller from Microchip's AVR family, ideal for embedded systems. Key application areas include:
- Industrial Control (automation, sensors, motor control)
- Consumer Electronics (appliances, smart devices)
- Automotive Systems (dashboard controls, lighting)
- Medical Devices (portable monitors, diagnostic tools)
- Communication Systems (modems, wireless modules)
- Robotics (motor drivers, sensor interfaces)
With 64KB Flash, 4KB SRAM, and 8MHz operation, it suits low-power, cost-sensitive designs requiring moderate processing. Peripherals like UART, SPI, I2C, ADC, and PWM enhance versatility.

Package

The ATMEGA64L-8AU comes in a TQFP-64 package (Thin Quad Flat Pack, 64 pins). It has a 10x10mm body size with a 0.8mm pin pitch. This surface-mount package is suitable for compact PCB designs and offers reliable performance for embedded applications. The "L" denotes low-voltage operation (2.7–5.5V), and "8AU" indicates 8MHz speed and industrial temperature range.
