AVR32DA32T-E/RXB

Overview

The AVR32DA32T-E/RXB is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz CPU with hardware multiplier. It includes 32 KB of Flash memory, 4 KB of SRAM, and 512 B of EEPROM. The device operates within a 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 32-pin VQFN package (RXB suffix) and supplied in tape and reel format (T suffix).

Feature Summary

• Supports Program and Debug Interface Disable (PDID) for secure firmware upgrades.
• Integrates intelligent analog features including a 12-bit ADC and Peripheral Touch Controller.
• Features an Event System for CPU-independent inter-peripheral signaling.
• Includes Configurable Custom Logic (CCL) with programmable Look-up Tables.

Applications

• Secure firmware upgrade implementations requiring code protection.
• Capacitive touch interface designs using buttons or sliders.
• Low-power applications utilizing multiple sleep modes.
• Industrial control systems operating in extended temperature environments.

Procurement Notes

Verify that the ordering suffix RXB corresponds to the 32-pin VQFN package and T indicates tape and reel packaging. Confirm the E suffix denotes the extended temperature range (-40°C to +125°C). Ensure compatibility with existing design footprints for the specific package style before procurement.

Selection Notes

Select this model when a 32-pin footprint is required alongside 32 KB of program memory. The extended temperature rating makes it suitable for harsh environments. Consider the PDID feature if security against unauthorized access is a priority over standard devices.

Part Context

This component belongs to the AVR DA(S) family, which offers vertical migration without code modification. It shares pin and feature compatibility with other members like the AVR32DA28 and AVR32DA48, allowing for flexible scaling based on I/O and memory requirements.
