AVR64EA48T-I/PT

Overview

The AVR64EA48T-I/PT is an 8-bit AVR microcontroller in a 48-pin TQFP package. It features 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 with a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC with 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 Event System for CPU-independent inter-peripheral signaling
• Includes accurate analog subsystems such as a 12-bit differential ADC with programmable gain amplifier (PGA)
• Supports true read-while-write operation for non-volatile memory access during program execution
• Integrates Configurable Custom Logic (CCL) with programmable Look-up Tables for advanced digital peripheral functions

Applications

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

Procurement Notes

Verify the 'T' suffix indicates Tape & Reel packaging and 'I' denotes Industrial temperature range (-40°C to +85°C). Confirm the 'PT' suffix corresponds to the TQFP package type. Ensure compatibility with the AVR EA family pinout if migrating from other variants within the series.

Selection Notes

Select this model when 64 KB of Flash and 6 KB of SRAM are required alongside a 48-pin form factor. The industrial temperature rating suits environments between -40°C and +85°C. Consider the integrated analog peripherals and event system for designs needing reduced external component count.

Part Context

This part belongs to the AVR64EA28/32/48 family, which shares full pin and feature compatibility for vertical migration without code modification. The AVR® EA Family utilizes the latest Microchip technologies, offering a flexible architecture with hardware multipliers running up to 20 MHz.
