AVR32DD28T-E/STX

Overview

The AVR32DD28T-E/STX is an 8-bit microcontroller from the AVR DD family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports an extended temperature range of -40°C to +125°C. It is housed in a VQFN-28 package (STX suffix) and supplied in tape and reel format (T suffix).

Feature Summary

Multi-Voltage I/O (MVIO) capability on PORTC for interfacing with different power domains.
Configurable Custom Logic (CCL) with four programmable Look-up Tables (LUTs).
Event System (EVSYS) for CPU-independent inter-peripheral signaling.
Automated Cyclic Redundancy Check (CRC) Flash memory scan.

Applications

Industrial control systems requiring multi-voltage domain communication.
Real-time control applications utilizing event-driven peripheral interactions.
Embedded designs needing robust analog features like differential ADC and DAC.
IoT devices operating across wide temperature ranges.

Procurement Notes

Verify that the ordering suffix 'T' corresponds to the Tape & Reel carrier type and 'STX' indicates the VQFN-28 package. Confirm the 'E' suffix denotes the Extended temperature range (-40°C to +125°C). Ensure the specific part number matches the required memory configuration of 64 KB Flash and 8 KB SRAM as defined in the AVR DD family datasheet DS40002315.

Selection Notes

Select this component when vertical migration within the AVR DD family is required without code modification. Choose this variant if the design necessitates the VQFN-28 package form factor combined with the extended temperature rating. Verify that the 64 KB Flash and 8 KB SRAM capacities align with application requirements compared to smaller variants like the AVR32DD28.

Part Context

This device belongs to the AVR DD family, which offers pin and feature compatibility across 14, 20, 28, and 32-pin packages. The AVR32DD28T-E/STX specifically provides 64 KB of Flash, distinguishing it from the 32 KB and 16 KB variants in the same package. It shares the same core architecture and peripheral set as other DDR/DD series members, enabling seamless horizontal and vertical migration.
