AVR32DA32-E/RXB

Overview

The AVR32DA32-E/RXB is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of self-programmable Flash, 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 temperatures from -40°C to +125°C. Key peripherals include a 12-bit ADC, three analog comparators, a DAC, two ZCDs, six USARTs, two SPIs, two TWIs, PTC, CCL, and TCA/TCB/TCD timers.

Feature Summary

Supports vertical migration without code modification across the AVR DA(S) family due to full pin and feature compatibility.
Integrates intelligent analog features including a 12-bit differential ADC, three analog comparators, and a 10-bit DAC.
Provides advanced digital peripherals such as Configurable Custom Logic (CCL), Peripheral Touch Controller (PTC), and Event System for inter-peripheral signaling.

Applications

Embedded control systems requiring low-power operation and flexible I/O configurations.
Applications utilizing capacitive touch interfaces via the Peripheral Touch Controller.
Industrial monitoring using analog comparators and zero-cross detectors.
Communication gateways leveraging multiple USART, SPI, and TWI interfaces.

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C). Confirm 'RXB' indicates the VQFN-32 package style. Ensure the specific part number matches the required memory size and peripheral count for the target application design.

Selection Notes

Select this component when extended temperature operation is required alongside standard AVR DA family features. Consider the 32-pin VQFN package constraints for PCB layout. Evaluate if the 32 KB Flash and 4 KB SRAM meet the application's code and data storage needs compared to larger variants in the series.

Part Context

This device belongs to the AVR DA family, which utilizes the latest Microchip technologies for flexible and low-power architectures. It shares architectural similarities with other AVR DA devices but is distinguished by its specific memory configuration and 32-pin package availability.
