AVR64DA32-I/RXB

Overview

The AVR64DA32-I/RXB is an 8-bit microcontroller from the AVR DA family, featuring a 32-pin VQFN package. It utilizes an AVR CPU with hardware multiplier running at up to 24 MHz. The device includes 64 KB of self-programmable Flash memory, 8 KB of SRAM, and 512 B of EEPROM. Key peripherals include a 12-bit differential ADC, 10-bit DAC, three analog comparators, and a Peripheral Touch Controller (PTC). It supports UPDI for programming and debugging.

Feature Summary

• Supports vertical migration within the AVR DA(S) family without code modification due to full pin and feature compatibility across variants.
• Integrates intelligent analog features including a 12-bit differential ADC and a 10-bit DAC with output buffer for signal conditioning.
• Provides advanced digital peripherals such as Configurable Custom Logic (CCL) and an Event System for CPU-independent inter-peripheral signaling.

Applications

• Analog signal conditioning
• Sensor applications
• IoT terminal nodes

Procurement Notes

Verify the ordering suffix RXB corresponds to the VQFN32 tape and reel carrier type. Confirm the 'I' suffix indicates the industrial temperature range of -40°C to +85°C. Ensure the specific part number matches the required package style and supply voltage specifications before finalizing procurement.

Selection Notes

Select this component when a 32-pin form factor is required alongside 64 KB of Flash memory. It is suitable for designs needing the Peripheral Touch Controller or multiple communication interfaces like USART and SPI. Consider the extended temperature variant if operation beyond 85°C is necessary.

Part Context

This device belongs to the AVR DA(S) family, which offers flexible low-power architecture. It shares core architectural features with other members like the AVR64DA28 and AVR64DA48, allowing for scalable design transitions based on pin count and peripheral requirements.
