AVR16EA28-E/SS

Overview

The AVR16EA28-E/SS 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. 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.

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 and window compare functions
Supports vertical migration without code modification across the AVR EA family due to full pin and feature compatibility

Applications

Real-time control systems
Sensor nodes
Secondary safety monitoring applications

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure the component matches the required extended industrial grade specifications. Cross-reference datasheet DS40002498A for complete electrical characteristics and timing parameters before finalizing procurement decisions.

Selection Notes

Select this model when a 28-pin SSOP package is required alongside 16 KB of program memory. It is suitable for designs needing high-precision analog inputs via the differential ADC or those requiring simultaneous host and client operation on the TWI bus. Consider the extended temperature range if operating in harsh environments.

Part Context

This component belongs to the AVR EA family, which utilizes the latest Microchip technologies for efficient real-time control. The family offers scalable memory options from 16 KB to 64 KB Flash while maintaining consistent peripheral sets and pinouts to facilitate easy design upgrades.
