AVR64EA48T-E/PT

Overview

The AVR64EA48T-E/PT is an 8-bit AVR microcontroller featuring a 20 MHz CPU, 64 KB Flash with read-while-write capability, and 6 KB SRAM. It operates within a 1.8 V to 5.5 V supply range across an extended temperature range of -40°C to +125°C. The device includes a 12-bit differential ADC with PGA, a 10-bit DAC, three USARTs, one SPI, and one TWI interface. It utilizes a TQFP-48 package.

Feature Summary

• Supports true read-while-write operations for uninterrupted code execution during memory reprogramming.
• Features a 12-bit differential ADC with programmable gain amplifier for high-precision signal acquisition in noisy environments.
• Includes Configurable Custom Logic (CCL) with four Look-up Tables for hardware logic implementation independent of the CPU.

Applications

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

Procurement Notes

Verify that the 'E' suffix confirms the extended industrial temperature rating (-40°C to +125°C). Confirm the 'T' suffix indicates tape and reel packaging rather than tube or tray. Ensure the specific part number matches the required pin count and memory configuration before finalizing orders.

Selection Notes

Select this variant when extended temperature operation up to 125°C is required compared to the standard industrial grade. The 48-pin package provides maximum peripheral availability within the EA family. Verify that the 64 KB Flash and 6 KB SRAM meet the application's storage requirements.

Part Context

This component belongs to the AVR® EA Family, which offers vertical migration compatibility without code modification. It shares architectural similarities with other devices in the series but is distinguished by its specific 64 KB Flash capacity and 48-pin form factor.

Replacement Considerations

AVR64EA48-I/PT serves as a direct functional substitute with identical specifications, differing only in the operating temperature range (Industrial vs. Extended).
