AVR32DA48T-E/6LX

Overview

The AVR32DA48T-E/6LX is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR 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 temperatures from -40°C to +125°C. It is housed in a 48-pin VQFN package (6x6 mm) and supplied in tape and reel format.

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 ADC, three analog comparators, and a Peripheral Touch Controller for capacitive touch applications.
• Provides advanced digital peripherals such as multiple USART, SPI, TWI interfaces, and a dedicated Event System for inter-peripheral signaling.

Applications

• Capacitive touch control panels using buttons, sliders, wheels, or 2D surfaces
• Power control systems utilizing Timer/Counter type D optimization
• Secure firmware upgrade implementations requiring Program and Debug Interface Disable

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and '6LX' indicates the VQFN48 package style. Confirm the 'T' suffix denotes tape and reel packaging. Ensure the specific part number matches the required memory size and peripheral configuration for your design.

Selection Notes

Select this component when a 48-pin footprint is required with high I/O count and integrated touch sensing capabilities. Consider the AVR32DA48T-E/6LX for designs needing extended temperature operation and robust security features like PDID. Evaluate the trade-off between the 32 KB Flash capacity and the available SRAM against application requirements.

Part Context

This part belongs to the AVR32DA48(S) device group within the broader AVR DA(S) family. It shares architectural similarities with AVR64DA and AVR128DA variants but offers lower memory capacities. The device is designed for general-purpose applications requiring low-power operation and flexible peripheral configurations.
