AVR32DA28-E/SP

Overview

The AVR32DA28-E/SP is an 8-bit microcontroller from the AVR DA(S) 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 bytes of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports up to 41 programmable I/O pins. Key peripherals include a 12-bit differential ADC, three analog comparators, a 10-bit DAC, and multiple communication interfaces such as USART, SPI, and TWI.

Feature Summary

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

Applications

Industrial control systems requiring multi-voltage operation
Smart home appliances with capacitive touch interfaces
IoT devices needing secure over-the-air updates
Battery-powered applications utilizing low-power sleep modes

Procurement Notes

Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C). Confirm the 'SP' suffix indicates the SPDIP package style. Ensure the specific part number matches the required pin count and memory configuration for your design.

Selection Notes

Select this model for designs requiring robust security features like PDID and high-performance analog peripherals. It is suitable for applications needing vertical migration within the AVR DA(S) family without code modification. Consider the 28-pin constraint when mapping all necessary I/O functions.

Part Context

This component belongs to the AVR DA(S) family, which utilizes the latest Microchip technologies for flexible low-power architectures. The DA series is designed for real-time control and offers horizontal and vertical migration paths across different pin counts and memory sizes within the same ecosystem.
