Microchip - Model AVR64DD28 -Multi-Voltage I/O Microcontroller

The family uses the latest Core Independent Peripherals with low-power features and 5V operation for increased noise immunity. The Multi-Voltage I/O system allows safe bi-directional communication with systems running at a different voltage. The Event System, Configurable Custom Logic (CCL), along with intelligent analog peripherals, like 12-bit differential ADC, Zero-Cross Detect (ZCD), 10-bit DAC together with the MVIO makes the AVR® DD family well suited for sensor applications, IoT end nodes, and other applications where signal conditioning or level-shifting is needed.

AVR64DD28
The AVR64DD28 will be available in TQFP and VQFN package options running at up to 24 MHz and with 64 KB Flash, 8 KB SRAM, and 256B of EEPROM.
The AVR64DD28 product supports four Multi-Voltage I/O channels capable of bi-directional communication with external devices running at a higher or lower voltage than the MCU itself. The MVIO system makes the AVR® DD a perfect device for board control, sensor applications, IoT end nodes, and other size constrained applications, and for sensor fusion in larger systems.
