AVR64DB64-E/MR with 8-bit Microcontrollers - MCU 64KB, VQFN64, 125C, 24MHz, 12b ADC, Comp, Opamp, MVIO, ZCD, DAC, UART, SPI, TWI is a high-performance, low-power, 8-bit AVR family microcontroller from Microchip. It features 64KB of program flash memory, 64-pin VQFN package with thermal pad, operating temperature range of -40°C to +125°C and speed range of up to 24MHz. It is equipped with on-chip features such as an on-chip temperature sensor, a 12-bit ADC for analog-to-digital conversion, an on-chip comparator, an operational amplifier, an on-chip motor control interface, a zero-crossing detector, an on-chip digital-to-analog converter, a universal asynchronous receiver/transmitter (UART), a serial peripheral interface (SPI) and a two-wire interface (TWI). Additional features include I/O port with interrupt-on-change, an SPI port, an synchronous/asynchronous operations, hardware/software full-duplex UART, a low-power Idle and power-down modes, an external and internal interrupt sources, and more. This device is designed for use in embedded applications such as solar panel controllers, automotive in-vehicle network, industrial motion control, lighting control, battery-backed power supplies, and more.
