AVR64DB48-E/6LX

Overview

The AVR64DB48-E/6LX is an 8-bit microcontroller from the AVR DB family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB Flash, 8 KB SRAM, and 512 B 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 utilizes a 48-pin VQFN package (suffix 6LX) and provides 41 I/O pins. Key peripherals include a 12-bit ADC, 10-bit DAC, three op amps, three ZCDs, and multiple communication interfaces.

Feature Summary

• Supports Multi-Voltage I/O (MVIO) on Port C for flexible logic level interfacing
• Includes analog signal conditioning with up to three op amps and internal resistor ladders
• Features an Event System for CPU-independent inter-peripheral signaling
• Provides Configurable Custom Logic (CCL) with programmable Look-up Tables

Applications

• Industrial control systems requiring extended temperature operation
• Smart energy metering applications
• Building automation and climate control devices
• Power control circuits utilizing Zero-Cross Detectors

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C). Confirm the '6LX' suffix corresponds to the 48-pin VQFN package. Ensure compatibility with existing designs by checking pinout alignment against the TQFP-48 variant if mechanical constraints require it.

Selection Notes

Select this model when extended industrial temperature ratings are required compared to the standard industrial version. The 48-pin VQFN package offers a compact footprint suitable for space-constrained PCB layouts. Verify that the 41 available I/O pins meet the system interface requirements.

Part Context

This component belongs to the AVR64DB28/32/48/64 series, which shares vertical migration compatibility without code modification. It serves as a mid-range option in the 48-pin category, balancing memory capacity with peripheral density. The device integrates advanced digital peripherals alongside accurate analog subsystems typical of the AVR DB architecture.

Replacement Considerations

AVR64DB48-I/6LX is the verified substitute offering identical specifications but with an Industrial temperature range (-40°C to +85°C).
