AVR64DA32T-E/RXB

Overview

The AVR64DA32T-E/RXB is an 8-bit microcontroller from the AVR DA(S) family, featuring a 32-pin VQFN package. It operates at up to 24 MHz with 64 KB of Flash, 8 KB of SRAM, and 512B of EEPROM. The device includes a 12-bit differential ADC with 14 channels, a 10-bit DAC, three analog comparators, and three zero-cross detectors. Communication interfaces include six USARTs, two SPIs, and two TWIs. It supports extended temperature ranges (-40°C to +125°C) and tape-and-reel packaging.

Feature Summary

Supports Program and Debug Interface Disable (PDID) for secure firmware protection
Integrates Peripheral Touch Controller (PTC) with Driven Shield+ technology
Features Configurable Custom Logic (CCL) with programmable Look-up Tables
Includes Event System for CPU-independent inter-peripheral signaling

Applications

Secure firmware upgrade implementations
Capacitive touch interface designs
Industrial control systems requiring high I/O counts
IoT nodes needing low-power sleep modes

Procurement Notes

Verify the 'E' suffix confirms the extended temperature range of -40°C to +125°C. Confirm the 'RXB' designation corresponds to the VQFN32 package style. Ensure the 'T' suffix indicates tape-and-reel carrier type as specified in the datasheet nomenclature. Cross-reference the full part number against official Microchip documentation to validate all ordering suffixes.

Selection Notes

Select this variant when 32 pins are required alongside 64 KB of program memory. The extended temperature rating suits harsh environments. The inclusion of PDID is critical for applications demanding code protection against unauthorized access. Verify that the 14 available ADC channels meet specific signal acquisition requirements.

Part Context

This component belongs to the AVR DA(S) family, which offers vertical migration compatibility without code modification. It shares architectural similarities with other pin-count variants like the AVR64DA28 and AVR64DA48. The series utilizes the latest AVR CPU technology with hardware multipliers and advanced digital peripherals for efficient processing.
