AVR32SD32T-I/PT

Overview

The AVR32SD32T-I/PT is an 8-bit microcontroller from the AVR SD family, featuring a dual-core architecture with two CPUs. It provides 32 kB of Flash program memory with ECC support and 4 kB of SRAM. The device operates at a maximum clock frequency of 20 MHz within a supply voltage range of 1.8 V to 5.5 V. It includes a 10-bit ADC with 13 channels, three comparators, two zero-crossing detectors, and two watchdog timers. Communication interfaces include three USARTs, two SPIs, and two TWI modules. The component is housed in a 32-pin TQFP package and supports operation temperatures from -40°C to +85°C.

Feature Summary

Dual-core architecture with two independent CPUs for enhanced processing capabilities
Integrated Error Correction Code (ECC) for Flash program memory reliability
Multiple analog peripherals including a 10-bit ADC, comparators, and zero-crossing detectors
Comprehensive digital interface suite with multiple USART, SPI, and TWI controllers

Applications

Industrial control systems requiring high reliability and error correction
Sensor interface applications utilizing multiple analog input channels
Communication gateways leveraging multiple serial interface protocols
Embedded systems demanding robust fault detection via watchdog and error control

Procurement Notes

Verify the specific suffix 'I/PT' corresponds to the industrial temperature range and TQFP-32 package configuration. Confirm that the dual-core feature set aligns with development toolchain support requirements. Ensure that the ECC functionality is properly configured in the firmware to maintain data integrity during operation. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when application logic requires parallel processing or redundant execution paths provided by the dual-core setup. Choose this MCU for designs needing extensive analog signal conditioning combined with robust digital communication links. Consider this part for environments where memory corruption risks necessitate hardware-level ECC protection. Evaluate pin count constraints against the 26 available I/O lines in the TQFP-32 package.

Part Context

This microcontroller belongs to the AVR SD series, which emphasizes reliability through features like ECC and error control mechanisms. The series targets applications where data integrity and fault tolerance are critical. The dual-core design differentiates it from single-core AVR variants, offering increased throughput potential. It integrates standard AVR peripheral sets with enhanced analog and safety features suitable for demanding embedded environments.
