AVR32EA32-E/PT

Overview

The AVR32EA32-E/PT is an 8-bit microcontroller from the AVR EA family, featuring a 32 KB Flash memory with read-while-write capability, 4 KB SRAM, and 512 bytes of EEPROM. It operates at clock speeds up to 20 MHz within a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with PGA, a 10-bit DAC, two analog comparators, and multiple communication interfaces including USART, SPI, and TWI. It utilizes a TQFP-32 package and supports an extended industrial temperature range of -40°C to +125°C.

Feature Summary

AVR CPU with hardware multiplier running at up to 20 MHz
Integrated Event System for CPU-independent peripheral signaling
Configurable Custom Logic (CCL) with programmable Look-up Tables
Single-pin Unified Program and Debug Interface (UPDI)

Applications

Closed-loop control systems
Secondary safety monitoring devices
Sensor nodes

Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C) as defined in the datasheet. Confirm the '/PT' suffix corresponds to the TQFP-32 package type. Ensure the component matches the preliminary data sheet DS40002497A specifications before integration.

Selection Notes

Select this variant when extended ambient temperature operation up to 125°C is required compared to the standard industrial grade. The 32 KB Flash and 4 KB SRAM configuration fits applications needing moderate code space and data handling. Verify pin compatibility if migrating from other AVR EA family members like the AVR32EA28 or AVR32EA48.

Part Context

This component belongs to the AVR® EA Family, which shares a flexible low-power architecture with advanced digital peripherals. The family allows vertical migration without code modification across different pin counts and memory sizes. The AVR32EA32 specifically provides a balance of features between the 28-pin and 48-pin variants.
