AVR64DD14-I/SL

Overview

The AVR64DD14-I/SL is an 8-bit microcontroller from Microchip Technology's AVR DD series, featuring a 64 kB system-in-programmable flash memory and 8 kB SRAM. It operates at a maximum clock frequency of 24 MHz within a 1.8 V to 5.5 V supply range. The device includes a 12-bit ADC with 7 channels, a 10-bit DAC, and multiple communication interfaces including two USARTs, SPI, and TWI. Packaged in SOIC-14, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Supports multi-voltage I/O (MVIO) for direct level shifting between different power domains without external converters.
Integrates intelligent analog peripherals including a zero-crossing detector and high-resolution ADC/DAC.
Features a robust event system and configurable custom logic to reduce system latency and CPU load.

Applications

Industrial control systems requiring real-time processing and noise immunity.
Smart home appliances utilizing multi-domain power architectures.
IoT devices needing low-latency peripheral interaction via the event system.

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm package integrity for the SOIC-14 form factor upon receipt. Ensure programming tools support the UPDI interface required for this AVR DD family. Cross-reference the full part number against the manufacturer's current lifecycle status to confirm availability.

Selection Notes

Select this model when 64 kB of program memory and 8 kB of RAM are required for complex 8-bit applications. The SOIC-14 package suits designs with limited board space but need for MVIO capabilities. Consider the AVR32DD series if higher performance or 32-bit architecture is needed, noting that code migration may require adjustments despite pin compatibility.

Part Context

This component belongs to the AVR DD family, which emphasizes intelligent analog features and multi-voltage operation. It shares architectural similarities with other AVR DD variants like the AVR16DD14 and AVR64DD32, offering vertical migration paths within the same pinout-compatible series. The family targets applications demanding high noise immunity and flexible I/O voltage levels.
