AVR16DD14-E/SL

Overview

The AVR16DD14-E/SL is an 8-bit microcontroller from the AVR DD Family, featuring a 16 KB Flash program memory and 2 KB SRAM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with 7 channels, a 10-bit DAC, two USARTs, SPI, and TWI interfaces. It utilizes a 14-pin SOIC package and supports extended temperature operation from -40°C to +125°C.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on PORTC for flexible voltage level interfacing.
• Includes Configurable Custom Logic (CCL) with four Look-up Tables for hardware logic implementation.
• Integrates a Zero-Cross Detector (ZCD) for AC mains detection applications.

Applications

• Low-power sensor nodes requiring multi-voltage interface compatibility.
• AC mains monitoring systems utilizing zero-cross detection capabilities.
• Industrial control modules using configurable custom logic for signal processing.

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C). Confirm the 'SL' suffix corresponds to the SOIC-14 package style. Ensure the specific revision matches the required datasheet version DS40002315C for accurate peripheral specifications.

Selection Notes

Select this component when vertical migration within the AVR DD family is required without code modification. Choose this model over lower pin-count variants if additional peripherals or I/O lines are necessary. Consider the 12-bit ADC resolution and MVIO support for mixed-signal environments.

Part Context

This part belongs to the AVR DD Family, which shares architectural similarities with the AVR64DD series. It offers horizontal migration options to other devices in the family by reducing pin counts while maintaining software compatibility. The device is designed for low-power applications with advanced analog features.

FAQ

Does the AVR16DD14 support simultaneous host and client operation on its TWI interface?

Yes, the TWI/I2C interface can operate simultaneously as both host and client on different pins.

What is the function of the MVIO feature on PORTC?

Multi-Voltage I/O (MVIO) allows PORTC pins to operate at a different voltage level than the core supply voltage, enabling direct interfacing with higher voltage peripherals.

How many external interrupts are available on the AVR16DD14?

The device provides 11 external interrupts available on general-purpose I/O pins.
