Microchip Technology D-Series AT32UC3 AVR 32-Bit MCUs

Microchip Technology D-Series AT32UC3 AVR 32-Bit MCUs are entry-level 32-bit microcontrollers that offer a rich feature set of devices containing a hardware QTouch® capacitive touch interface, Full-Speed USB Device, RTC with calendar, 10-bit ADC, USART, SPI, TWI, PWM and I2S. The low-power UC3D embeds SleepWalking™ technology that allows a peripheral to wake the device from sleep mode. The UC3D features a built-in capacitive touch module supporting up to 25 channels in hardware, and each channel can be configured as buttons, sliders, and wheels. The Glue Logic Controller (GLOC) contains programmable logic and lookup tables that can be connected to GPIO pins, which can reduce the number of external components. The UC3D is pin-compatible with the UC3B Series. The UC3B offers higher memory densities, USB OTG, and a migration path for UC3D customers requiring more functionality and performance.
