AVR64DD20-E/SO

Overview

The AVR64DD20-E/SO is a microcontroller from the AVR DD Family, featuring an AVR CPU with hardware multiplier running at clock speeds up to 24 MHz. It includes 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates within an extended temperature range of -40°C to +125°C and is housed in a 28-pin SOIC package.

Feature Summary

Supports flexible low-power architecture with Event System and intelligent analog features
Includes Multi-Voltage I/O (MVIO) on PORT C for selectable input voltage thresholds
Features automated Cyclic Redundancy Check (CRC) Flash memory scan for data integrity

Applications

Industrial control systems requiring extended temperature operation
Power control applications utilizing optimized PWM timers
Embedded systems needing multi-voltage I/O interfacing

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'SO' indicates the SOIC package style. Ensure compatibility with the AVR DD Family pinout and software libraries. Confirm supply voltage requirements align with the specified 1.8V to 5.5V operating range before integration.

Selection Notes

Select this model when 64 KB Flash and 8 KB SRAM are required alongside 28-pin availability. The extended temperature rating suits harsh environments. Consider vertical migration within the DD family for feature scaling without code modification. Verify peripheral needs against the specific count available in the 20-pin variant versus larger packages.

Part Context

This component belongs to the AVR DD Family, which offers vertical migration capabilities without code changes across different pin counts and memory sizes. It shares architectural similarities with other devices in the series, such as the AVR64DD28 and AVR64DD32, differing primarily in I/O count and package options.

Replacement Considerations

AVR64DD28-E/SO and AVR64DD32-E/SO are pin-compatible alternatives within the same family offering increased I/O resources. Smaller variants like AVR32DD20 or AVR16DD20 reduce pin counts and features but maintain software compatibility.
