AVR16EA28-I/SS

Overview

The AVR16EA28-I/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 industrial temperature range of -40°C to +85°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 analog comparators
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 ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and '/SS' indicates the SSOP-28 package. Confirm the datasheet revision matches the specific production lot requirements. Ensure the component source is authorized to guarantee authenticity and traceability for industrial-grade specifications.

Selection Notes

Select this model when 16 KB of Flash and 2 KB of SRAM are sufficient for the application logic. Choose the industrial grade variant for environments requiring operation between -40°C and +85°C. Consider the 28-pin SSOP package if board space constraints align with its footprint compared to larger pin-count variants in the same family.

Part Context

This component belongs to the AVR EA family, which utilizes the latest Microchip technologies including advanced digital peripherals and precise analog subsystems. The family offers horizontal and vertical migration paths, allowing designers to scale pin counts and memory sizes while maintaining software compatibility across devices like the AVR32EA28 and AVR64EA28.
