AVR32SD28T-E/SS

Overview

The AVR32SD28T-E/SS is an 8-bit microcontroller from Microchip Technology, featuring the AVR core architecture. It provides 32 kB of program memory with ECC support and 4 kB of SRAM data memory. The device operates at a maximum clock frequency of 20 MHz and utilizes an SSOP-20 package. Key peripherals include two ADCs, three comparators, two zero-crossing detectors (ZCD), and two watchdog timers (WDT). Communication interfaces consist of three USARTs, two SPI modules, and two TWI interfaces. It supports MVIO technology for flexible I/O voltage levels and includes PDID functionality.

Feature Summary

Dual CPU architecture with error control features
MVIO technology for configurable I/O voltage levels
Integrated peripheral debug ID (PDID) capability
Multiple analog and timing peripherals including ZCD and WDT

Applications

Industrial control systems requiring dual-core redundancy
Smart metering applications with high reliability needs
Motor control circuits utilizing zero-crossing detection
Embedded systems requiring robust error correction in program memory

Procurement Notes

Verify availability status as the component may be listed as not orderable or restricted in certain regions. Confirm the specific suffix indicates the tape and reel packaging format. Ensure compatibility with existing design infrastructure regarding the SSOP-20 package dimensions and pinout configuration before finalizing procurement plans.

Selection Notes

Select this model when dual CPU execution and memory error correction are required within a compact 20-pin form factor. Consider the 20 MHz operational speed and available communication interfaces against system latency requirements. Evaluate the need for MVIO flexibility if interfacing with varying voltage logic levels is necessary for the target application design.

Part Context

This part belongs to the AVR32SD series, designed for applications demanding enhanced reliability through dual-core processing and error correction. It complements other AVR devices by offering specialized features like PDID and extensive analog peripherals in a small outline package suitable for space-constrained embedded designs.
