Manufacturer
Microchip Technology is a leading American semiconductor company specializing in microcontrollers (MCUs), analog, and Flash-IP solutions. 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
- 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.
