AVR32EA28T-E/SS

Overview

The AVR32EA28T-E/SS is an 8-bit microcontroller from the AVR® EA family, featuring a CPU with hardware multiplier running at up to 20 MHz. It includes 32 KB of in-system programmable Flash memory with read-while-write capability, 4 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. It is housed in a 28-pin SSOP package.

Feature Summary

Features a flexible low-power architecture with Event System for CPU-independent inter-peripheral signaling
Includes accurate analog subsystems such as a 12-bit differential ADC with PGA and a 10-bit DAC
Supports advanced digital peripherals including Configurable Custom Logic (CCL) and multiple timer/counters
Provides single pin Unified Program and Debug Interface (UPDI) for programming and debugging

Applications

Real-time control systems
Sensor nodes
Secondary safety monitoring applications
Closed-loop control system designs

Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'T' indicates tape and reel packaging. Confirm that the datasheet version matches the required revision for design-in. Ensure compatibility with existing toolchains and UPDI programmers before finalizing procurement orders.

Selection Notes

Select this component when extended industrial temperature operation is required alongside standard AVR EA family features. It offers vertical migration compatibility with other devices in the series without code modification. Consider the 28-pin form factor if board space is limited but full peripheral sets are needed.

Part Context

This part belongs to the AVR® EA Family, which utilizes the latest Microchip technologies for efficient embedded control. The family provides horizontal and vertical migration paths across different pin counts and memory sizes while maintaining feature compatibility.
