AVR128DA28T-E/SS

Overview

The AVR128DA28T-E/SS is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz CPU, 128 KB Flash, 16 KB SRAM, and 512 B EEPROM. It operates within a 1.8 V to 5.5 V supply range across -40°C to +125°C temperatures. The device includes a 12-bit ADC, 10-bit DAC, three analog comparators, three zero-cross detectors, and a Peripheral Touch Controller. It utilizes SSOP-28 packaging with tape-and-reel delivery.

Feature Summary

• Supports vertical migration without code modification due to full pin and feature compatibility within the AVR DA family.
• Integrates intelligent analog features including a 12-bit differential ADC, 10-bit DAC, and configurable custom logic.
• Provides advanced digital peripherals such as multiple USART, SPI, TWI interfaces, and an event system for inter-peripheral signaling.

Applications

• Industrial control systems requiring robust peripheral integration
• Smart home appliances utilizing capacitive touch interfaces
• Battery-powered devices benefiting from low-power architecture

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and 'E' indicates extended temperature range (-40°C to +125°C). Confirm the 'SS' suffix matches the required SSOP-28 package style. Ensure the component meets RoHS compliance standards before finalizing procurement orders.

Selection Notes

Select this variant when extended industrial temperature operation is required alongside high memory capacity. The tape-and-reel format supports automated surface-mount assembly processes. Consider the specific I/O count and peripheral availability relative to other pin counts in the AVR DA family.

Part Context

This component belongs to the AVR128DA series, which offers 128 KB of Flash memory. It shares architectural similarities with AVR32DA and AVR64DA variants but provides higher storage capacity. The device is designed for applications needing enhanced performance over legacy AVR controllers while maintaining backward compatibility.

Replacement Considerations

AVR128DA28-I/SS serves as the industrial temperature equivalent. AVR128DA28T-E/MR offers identical functionality in a QFN-64 package. Verify pinout compatibility when substituting between different package styles within the same memory class.
