AVR64DB32T-E/RXB

Overview

The AVR64DB32T-E/RXB is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier and operating at clock speeds up to 24 MHz. It includes 64 KB of self-programmable Flash memory, 8 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 industrial temperature range of -40°C to +125°C. It is housed in a 32-pin VQFN package with tape and reel packaging.

Feature Summary

Supports multi-voltage I/O (MVIO) on Port C for flexible interfacing
Includes an event system for CPU-independent peripheral signaling
Features configurable custom logic with programmable look-up tables
Provides analog signal conditioning via op-amps and window comparators

Applications

Industrial control systems requiring real-time processing
Smart home appliances with multi-voltage requirements
IoT terminal nodes utilizing low-power sleep modes
Sensor applications involving analog signal conditioning

Procurement Notes

Verify the ordering suffix 'RXB' corresponds to the 32-pin VQFN package and 'T' indicates tape and reel carrier type. Confirm the 'E' suffix denotes the extended temperature range (-40°C to +125°C). Ensure compatibility with existing PCB footprints for the 5x5 mm VQFN outline before finalizing procurement orders.

Selection Notes

Select this component when vertical migration within the AVR DB family is required without code modification. Choose this model if specific pin counts or feature sets of other variants are unnecessary. Consider the extended temperature rating for harsh environments. Verify that the 64 KB Flash and 8 KB SRAM meet application memory constraints.

Part Context

This part belongs to the AVR64DB28/32/48/64 series, which shares a common architecture and instruction set. Devices in this family offer full pin and feature compatibility for vertical migration. The AVR64DB32 variant specifically provides 32 pins, balancing peripheral availability with compact footprint requirements compared to larger packages.
