AVR64EA48-E/6LX

Overview

The AVR64EA48-E/6LX is an 8-bit microcontroller from the AVR EA family, featuring a 48-pin TQFP package and an extended industrial temperature range of -40°C to +125°C. It utilizes an AVR CPU with a hardware multiplier running 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 a programmable gain amplifier (PGA), a 10-bit DAC, two analog comparators, three USARTs, one SPI, and one TWI interface.

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 PGA and multiple voltage references.
• Supports advanced digital peripherals including Configurable Custom Logic (CCL) with four Look-up Tables.
• Provides true simultaneous read-while-write operation for Flash memory to ensure uninterrupted code execution.

Applications

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

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and '/6LX' indicates the specific 48-pin TQFP package variant. Confirm the datasheet revision matches the preliminary status noted in the source material. Ensure compatibility with the UPDI programming interface requirements for your development environment.

Selection Notes

Select this component when an extended operating temperature range up to +125°C is required compared to the standard industrial version. The 48-pin configuration provides access to all AVR64EA features, including the full set of I/O pins and peripheral channels. Consider the 12-bit ADC resolution and PGA if high-precision signal acquisition is necessary for the application design.

Part Context

This part belongs to the AVR64EA28/32/48 series within the broader AVR EA family. It shares the same core architecture and peripheral set as the 28-pin and 32-pin variants, differing primarily in pin count and available I/O resources. Vertical migration within the family is supported without code modification due to pin and feature compatibility.

Replacement Considerations

AVR64EA48-I/PT: Identical specifications except for the industrial temperature range (-40°C to +85°C).

FAQ

What does the 'E' suffix indicate in the part number?

The 'E' suffix denotes the extended temperature range rating, allowing operation from -40°C to +125°C.

Does the device support simultaneous reading and writing to Flash?

Yes, the 64 KB Flash memory supports true read-while-write operations, enabling continuous code execution during memory reprogramming.
