W25Q32RVSSJM TR

Memory IC Overview

The W25Q32RVSSJM TR is a 32 Mbit (4M x 8) NOR flash memory IC manufactured by Winbond Electronics. It utilizes the SpiFlash series architecture and supports Dual, Quad SPI, and QPI interfaces with a maximum clock frequency of 133 MHz. The device operates within a voltage range of 2.7V to 3.6V and features an 8-SOIC package. It includes 4Kb uniform sector erasing capabilities and maintains data retention for ten years.

Memory IC Feature Summary

• Supports high-speed Dual, Quad SPI, and QPI interface modes for efficient data transfer.
• Features 4Kb uniform sector organization for flexible block erasing.
• Operates across an extended industrial temperature range from -40°C to 105°C.

Memory IC Applications

• Firmware storage in embedded systems
• Code execution in XIP applications
• Data logging in industrial controllers

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging versus tube variants when sourcing. Confirm current lifecycle status directly with Winbond as availability fluctuates. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Check for recent Product Change Notifications regarding manufacturing site updates or material composition changes before finalizing procurement plans.

Memory IC Selection Notes

Select this component for designs requiring non-volatile code storage with moderate speed requirements. The 32 Mbit capacity suits small firmware images. Verify system voltage stability within the 2.7V to 3.6V range. Consider thermal management for the 8-SOIC package if operating near the upper temperature limit. Compare against W25Q32JV series if Double Transfer Rate (DTR) support is required for higher throughput.

Memory IC Part Context

This part belongs to the Winbond W25Q32 family of serial NOR flash memories. It shares architectural similarities with other members like W25Q32RVSSJQ and W25Q32RVCNJQ. The primary distinction lies in the package type and shipping configuration. It serves as a standard solution for cost-sensitive consumer and industrial electronics needing reliable program storage.

Memory IC Replacement Considerations

W25Q32RVSSJQ offers identical electrical specifications but may differ in packaging format. W25Q32RVCNJQ provides a similar pinout and performance profile. Verify that any substitute matches the exact voltage and temperature ratings. Ensure the replacement supports the same interface modes used in the original design.
