AVR16EA48-E/PT

Overview

The AVR16EA48-E/PT is an 8-bit microcontroller from the AVR EA family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 16 KB of Flash memory with read-while-write capability, 2 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended industrial temperature range of -40°C to +125°C. It is housed in a TQFP-48 package and provides up to 42 programmable I/O pins.

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 advanced digital peripherals including Configurable Custom Logic (CCL) Look-up Tables
• Provides true simultaneous read-while-write operation for non-volatile memory access

Applications

• Closed-loop control systems design
• Secondary safety monitoring equipment
• Sensor nodes
• Industrial and consumer appliance applications

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'E' indicates the extended temperature range (-40°C to +125°C), while 'PT' denotes the TQFP-48 package type. Confirm the presence of the 'T' suffix if tape and reel packaging is required; its absence implies tube or tray packaging. Ensure the component version aligns with the preliminary datasheet DS40002498A.

Selection Notes

Select this part when vertical migration within the AVR EA family is needed without code modification due to full pin and feature compatibility. Choose the extended temperature grade for environments exceeding standard industrial limits. Consider the 48-pin variant for higher I/O counts compared to the 28 or 32-pin options.

Part Context

This component belongs to the AVR EA family, which utilizes the latest Microchip technologies for efficient real-time control. The family offers horizontal migration capabilities by reducing pin counts and features, while maintaining software compatibility across different memory sizes and package types within the same series.
