AVR64DB48T-E/6LX

Overview

The AVR64DB48T-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 1.8 V to 5.5 V supply range and supports -40°C to +125°C temperatures. It utilizes a 48-pin VQFN package (suffix 6LX) in tape and reel format (suffix T). Key peripherals include a 12-bit ADC, 10-bit DAC, three op amps, three ZCDs, multiple timers, and standard communication interfaces.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing.
• Includes analog subsystems such as three op amps, three zero-cross detectors, and a 12-bit differential ADC.
• Supports CPU-independent peripheral signaling via the Event System.
• Provides Configurable Custom Logic (CCL) with programmable Look-up Tables.

Applications

• Industrial control systems requiring extended temperature operation
• Motor control applications utilizing zero-cross detection and PWM timers
• Battery-powered devices operating at low voltages
• Smart energy metering and sensing applications

Procurement Notes

Verify that the ordering suffix 'T' corresponds to Tape & Reel packaging and '6LX' denotes the VQFN48 package style. Confirm the 'E' suffix indicates the Extended temperature range (-40°C to +125°C). Ensure compatibility with the specific pinout of the VQFN48 footprint during PCB design. Cross-reference the datasheet DS40002300B for exact electrical characteristics.

Selection Notes

Select this component when vertical migration within the AVR DB family is required without code modification. Choose the 48-pin variant if more General Purpose I/O or peripheral channels are needed compared to the 28 or 32-pin versions. The Extended temperature rating makes it suitable for harsh environments where Industrial grade parts may fail.

Part Context

This part belongs to the AVR64DB28/32/48/64 series, which shares identical memory sizes and core features across pin counts. The 'AVR64DB48' designation indicates 64 KB Flash and 48 pins. The 'T' suffix specifies the carrier type as Tape & Reel, while '6LX' identifies the specific 48-pin VQFN package geometry.

Replacement Considerations

Devices within the same AVR DB family (e.g., AVR64DB28, AVR64DB32, AVR64DB64) are fully pin and feature compatible for vertical migration. Other packages like TQFP (PT) or SSOP (SS) offer alternative form factors but require schematic adjustments due to different pinouts.

FAQ

What does the '6LX' package suffix indicate?

The '6LX' suffix indicates a 48-pin Very Thin Quad Flat No-lead (VQFN) package with dimensions of 5x5 mm.

Is the AVR64DB48T-E/6LX compatible with other AVR DB devices?

Yes, it is vertically compatible with AVR64DB28, AVR64DB32, and AVR64DB64, allowing for code reuse across the family.
