AVR32DA32-I/RXB

Overview

The AVR32DA32-I/RXB is an 8-bit microcontroller from the AVR DA family, featuring a 32 KB Flash memory, 4 KB SRAM, and 512 B EEPROM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device is housed in a 32-pin VQFN package (RXB) and supports industrial temperature ranges (-40°C to +85°C). Key peripherals include a 12-bit ADC, DAC, three USARTs, two SPIs, two TWIs, and a Peripheral Touch Controller.

Feature Summary

Supports vertical migration within the AVR DA(S) family without code modification due to full pin and feature compatibility.
Includes Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
Features an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).

Applications

Secure firmware upgrade implementations requiring PDID protection
Capacitive touch applications using the Peripheral Touch Controller
Industrial control systems operating within the -40°C to +85°C range

Procurement Notes

Verify the specific ordering suffix RXB confirms the 32-pin VQFN package style. Confirm the 'I' suffix indicates the Industrial temperature range (-40°C to +85°C). Ensure the base part number matches the 32 KB Flash variant within the AVR32DA series. Cross-reference the datasheet DS40002228 for exact pinout and electrical specifications.

Selection Notes

Select this component when a 32-pin footprint is required alongside 32 KB of program memory. It is suitable for designs needing advanced analog features like the 12-bit ADC and PTC. Consider the 24 MHz processing speed and the availability of multiple communication interfaces such as USART and SPI for system integration.

Part Context

This device belongs to the AVR DA(S) family, which utilizes the latest Microchip technologies for low-power architecture. It shares architectural similarities with other members like the AVR32DA28 and AVR32DA48, allowing for flexible scaling based on pin count and peripheral requirements while maintaining software compatibility.
