AVR64EA48T-E/6LX

Overview

The AVR64EA48T-E/6LX is an 8-bit microcontroller from the AVR EA family, featuring a 48-pin TQFP package. It includes 64 KB of Flash memory with read-while-write capability, 6 KB of SRAM, and 512 bytes of EEPROM. The device operates at clock speeds up to 20 MHz and supports a supply voltage range of 1.8 V to 5.5 V. It offers 42 programmable I/O pins and operates within an extended temperature range of -40°C to +125°C.

Feature Summary

• AVR CPU with hardware multiplier running at up to 20 MHz
• Integrated 12-bit differential ADC with Programmable Gain Amplifier (PGA)
• Configurable Custom Logic (CCL) with four Look-up Tables (LUTs)
• Event System for CPU-independent inter-peripheral signaling

Applications

• Real-time control systems
• Sensor nodes
• Secondary safety monitoring equipment

Procurement Notes

Verify the specific ordering suffix '6LX' against official Microchip documentation to confirm exact packaging or marking variations. Ensure the component matches the AVR64EA48 pinout and electrical specifications defined in the datasheet DS40002443A before integration into designs.

Selection Notes

Select this variant for applications requiring extended industrial temperature ranges (-40°C to +125°C). The 48-pin TQFP package provides ample I/O options for complex interfaces. Consider the integrated analog peripherals and event system for reducing external component count in signal processing tasks.

Part Context

This part belongs to the AVR64EA28/32/48 series, which shares a common architecture across different pin counts. Vertical migration within the family allows code reuse without modification due to full pin and feature compatibility. The device utilizes the UPDI interface for programming and debugging.

Replacement Considerations

AVR64EA48T-I/PT: Industrial temperature grade (-40°C to +85°C) alternative.
