AVR16DD20-E/REB [Microchip]

Code Examples

The AVR® DD family of microcontrollers feature the well-known AVR® CPU, now running at up to 24 MHz across the full supply voltage range of 1.8V to 5.5V. The family includes 16 KB, 32 KB, and 64 KB Flash variants in 14 to 32-pin package options. The AVR DD family is designed to bring real-time control and multi-voltage operation to applications including industrial control, home appliance products, automotive, and Internet of Things (IoT).

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.

AVR16DD20

The AVR16DD20 will be available in TQFP and VQFN package options running at up to 24 MHz and with 16 KB Flash, 2 KB SRAM, and 256B of EEPROM.

The AVR16DD20 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.
