The ATMEGA64M1-MU is a small, low-power microcontroller produced by Microchip. It is part of the MegaAVR family of microcontrollers and is based on an AVR architecture. This chip is ideal for embedded applications that require a high level of performance, low power consumption, and advanced peripherals. It offers 64KB of Flash memory and 2KB of SRAM, as well as 32-channels of 10-bit A/D converter, an advanced interrupt controller, and a timer/counter. The ATMEGA64M1-MU also includes 6 on-chip UARTs for communication, 2 SPI for communication among self-contained devices, and an I2C Master for communication with external devices. The chip is available in a 64-pin TQFP package, operates on a single 2.7V to 5.5V voltage supply, and can operate at up to 20MHz.
