AVR64DA48T-I/6LX

Overview

The AVR64DA48T-I/6LX is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz CPU, 64 KB Flash, 8 KB SRAM, and 512 B EEPROM. It utilizes a VQFN-48 package (suffix 6LX) with an industrial temperature range of -40°C to +85°C. Key peripherals include six USARTs, two SPIs, two TWIs, a 12-bit ADC, three analog comparators, a DAC, three zero-cross detectors, and a Peripheral Touch Controller.

Feature Summary

• Supports vertical migration within the AVR DA(S) family without code modification due to 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.

Applications

• Secure firmware upgrade implementations requiring PDID protection
• Capacitive touch interfaces using the Peripheral Touch Controller
• Power control applications utilizing the TCD timer and zero-cross detectors

Procurement Notes

Verify that the ordering suffix '6LX' corresponds to the VQFN-48 package style as defined in the datasheet designation table. Confirm the 'I' suffix indicates the industrial temperature range (-40°C to +85°C). Ensure the 'T' suffix matches the required tape and reel carrier type for automated assembly processes.

Selection Notes

Select this component when a 48-pin form factor is required alongside high peripheral density, such as six USARTs and extensive touch capabilities. The device supports horizontal migration to lower pin counts if fewer I/O resources are needed, while maintaining vertical compatibility with other AVR DA devices.

Part Context

This part belongs to the AVR64DA28/32/48/64(S) series, which shares a common architecture and instruction set. The '6LX' suffix specifically identifies the VQFN 6x6 mm package variant within the 48-pin count category, distinguishing it from TQFP or SOIC packages.

Replacement Considerations

AVR64DA48-I/PT: Identical electrical specifications and memory but uses a TQFP-48 package instead of VQFN-48.

FAQ

What does the '6LX' suffix indicate?

The '6LX' suffix designates the VQFN 6x6 mm package style for the 48-pin device.

Does this device support the PDID security feature?

Yes, the AVR DA(S) family includes the Program and Debug Interface Disable (PDID) feature to prevent unauthorized access to Flash memory via UPDI.
