AVR64DB32-E/RXB

Overview

The AVR64DB32-E/RXB is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 64 KB of 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 temperature range of -40°C to +125°C. It is housed in a VQFN-32 package with 26 general-purpose I/O pins.

Feature Summary

Includes multi-voltage I/O (MVIO) on Port C for flexible interface compatibility
Features an event system for CPU-independent inter-peripheral signaling
Integrates analog signal conditioning peripherals including op amps and zero-cross detectors

Applications

Industrial control systems requiring robust peripheral interfaces
Smart energy metering applications utilizing zero-cross detection
Sensor nodes requiring low-power operation and event-driven processing

Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'RXB' denotes the VQFN-32 package style. Ensure the procurement documentation matches the exact part number to confirm the correct carrier type and manufacturing revision associated with this component variant.

Selection Notes

Select this component when vertical migration within the AVR DB family is required without code modification. It is suitable for designs needing high-performance analog features like op amps and ZCDs alongside standard communication interfaces. Consider the extended temperature grade if the application environment exceeds industrial limits.

Part Context

This device belongs to the AVR DB family, which offers pin and feature compatibility across varying memory sizes. It shares architectural similarities with other AVR DB variants but provides specific memory capacities and peripheral counts tailored for 32-pin form factors. The family emphasizes flexibility through its advanced digital peripherals and accurate analog subsystems.
