AVR64EA48-I/6LX

Overview

The AVR64EA48-I/6LX is an 8-bit microcontroller from the Microchip AVR® EA family, featuring a 48-pin TQFP package. It utilizes an AVR CPU with a hardware multiplier operating at up to 20 MHz. The device includes 64 KB of in-system programmable Flash memory with read-while-write capability, 6 KB of SRAM, and 512 bytes of EEPROM. Key peripherals include a 12-bit differential ADC with PGA, a 10-bit DAC, two analog comparators, three USARTs, one SPI, and one TWI interface. It supports industrial temperature ranges (-40°C to +85°C) and operates on a supply voltage between 1.8 V and 5.5 V.

Feature Summary

• Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
• Includes accurate analog subsystems such as a 12-bit differential ADC with a programmable gain amplifier (PGA).
• Supports vertical migration within the AVR EA family without code modification due to pin and feature compatibility.
• Integrates advanced digital peripherals including Configurable Custom Logic (CCL) with programmable Look-up Tables.

Applications

• Real-time control systems requiring high-speed integrated analog processing.
• Sensor nodes designed for efficient signal measurement in noisy environments.
• Secondary safety monitoring applications in industrial or automotive contexts.

Procurement Notes

Verify that the '6LX' suffix corresponds to the specific tape and reel carrier type intended for automated assembly. Confirm the 'I' designation indicates the industrial temperature range (-40°C to +85°C). Ensure the datasheet version matches the preliminary status noted in source materials, as specifications may be subject to change before final release.

Selection Notes

Select this model when a 48-pin form factor is required alongside 64 KB of Flash memory. It is suitable for designs needing simultaneous read-while-write operations during programming. Consider this part if the application benefits from the dual-mode TWI operation or requires the specific I/O count provided by the 48-pin variant compared to smaller packages.

Part Context

This component belongs to the AVR64EA28/32/48 series, which shares a common core architecture but varies in pin count and peripheral availability. The 48-pin version offers the highest number of general-purpose I/O pins within this specific memory tier. It is designed for horizontal migration to lower pin counts or vertical migration to higher memory devices within the same family.
