AVR32DA28-I/SS

Overview

The AVR32DA28-I/SS is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of self-programmable Flash memory, 4 KB of SRAM, and 512 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to +85°C. Key peripherals include up to five USARTs, two SPI interfaces, two TWI/I2C controllers, a 12-bit differential ADC, a 10-bit DAC, three analog comparators, and a Peripheral Touch Controller (PTC).

Feature Summary

Supports Program and Debug Interface Disable (PDID) for secure firmware protection.
Integrates an Event System for CPU-independent inter-peripheral signaling.
Includes Configurable Custom Logic (CCL) with programmable Look-up Tables.
Features a Peripheral Touch Controller (PTC) with Driven Shield+ technology.

Applications

Secure embedded control systems requiring firmware authentication.
Industrial automation devices utilizing multiple serial communication protocols.
Applications involving capacitive touch user interfaces.
Power control circuits using Timer/Counter type D (TCD).

Procurement Notes

Verify that the ordering suffix 'I' corresponds to the required industrial temperature range (-40°C to +85°C). Confirm the 'SS' package designation matches the SSOP-28 form factor needed for the design. Ensure the specific part number aligns with the datasheet DS40002228C specifications before finalizing procurement.

Selection Notes

Select this component when vertical migration within the AVR DA(S) family is required without code modification. It is suitable for designs needing high peripheral density in a 28-pin package. Consider the PDID feature if security against remote attacks is a priority. Verify that the 32 KB Flash capacity meets application storage requirements.

Part Context

This device belongs to the AVR® DA(S) family, which utilizes the latest Microchip technologies for flexible low-power architecture. The AVR32DA28 variant serves as the entry point for the 28-pin package options, offering full pin and feature compatibility with higher-memory variants like the AVR64DA28 and AVR128DA28 for easy scaling.
