AVR64DB48-I/6LX

Overview

The AVR64DB48-I/6LX is an 8-bit microcontroller from the AVR DB family, utilizing the AVR CPU with a hardware multiplier running at clock speeds up to 24 MHz. It features 64 KB of Flash memory, 8 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperature ranges (-40°C to +85°C). It includes advanced peripherals such as a 12-bit ADC, three analog comparators, three op amps, and a DAC.

Feature Summary

Multi-Voltage I/O (MVIO) on Port C allows flexible interfacing with different voltage levels.
Integrated Analog Signal Conditioning peripheral provides up to three op amps with internal resistor ladders for various configurations without external components.
Event System enables CPU-independent and predictable inter-peripheral signaling to offload processing tasks.

Applications

Battery-powered applications requiring low-power operation and fast wake-up times.
Building and climate control systems utilizing analog signal conditioning.
Utility meters with RF connectivity and ZigBee integration.

Procurement Notes

Verify the specific ordering suffix '6LX' corresponds to the VQFN48 package style in official Microchip documentation. Confirm that the 'I' designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the Unified Program and Debug Interface (UPDI) used for programming these devices.

Selection Notes

Select this component when vertical migration within the AVR DB family is needed without code modification. Consider the 64 KB Flash size if larger software stacks are required compared to smaller pin-count variants. Evaluate the availability of 41 programmable I/O pins and the integrated analog subsystems for signal processing needs.

Part Context

This part belongs to the AVR64DB28/32/48/64 series, which shares fully pin and feature-compatible architectures across the family. Devices allow for vertical migration without code changes, enabling designers to scale memory and I/O capabilities while maintaining software compatibility.
