W25Q32FVSSJF TR

Memory IC Overview

The W25Q32FVSSJF TR is a 32-Mbit (4M x 8) SPI NOR Flash memory component manufactured by Winbond Electronics. It operates within a supply voltage range of 2.7V to 3.6V and supports clock frequencies up to 104 MHz in Quad I/O and QPI modes. The device features uniform 4-KB sector erasure with block sizes of 32 KB or 64 KB, housed in an 8-SOIC package. It includes hardware write protection, security registers, and supports page programming times of approximately 0.7 ms.

Memory IC Feature Summary

• Supports Single, Dual, and Quad SPI interfaces along with Quad Peripheral Interface (QPI) for flexible data transfer rates.
• Provides hardware and software write protection mechanisms including individual block/sector locking and OTP security registers.
• Features uniform 4-KB sector erase architecture allowing granular data management and efficient firmware updates.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics firmware repositories
• Industrial control system data logging

Memory IC Procurement Notes

Verify the specific suffix 'JF' against the official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the 'TR' designation matches the required reel packaging quantity for your assembly line. Cross-reference RoHS compliance status with current environmental regulations before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a standard 8-pin SOIC footprint is required for 32-Mbit capacity. Compare performance metrics such as read speed and power consumption against alternative packages like TFBGA if space constraints differ. Confirm that the operating temperature range meets the specific environmental requirements of the target application board.

Memory IC Part Context

This part belongs to the W25Q32 series of SpiFlash memories, designed for high-reliability data storage. The series is widely used in applications demanding robust firmware integrity and fast boot times. The SOIC-8 package offers a balance between pin count and physical size for general-purpose embedded designs.

Memory IC Replacement Considerations

Check for direct substitutes within the same family, such as W25Q32FVSSIQ or W25Q32JVSSIQ, ensuring interface compatibility. Verify that any replacement maintains the same voltage range and package dimensions to fit existing PCB footprints without redesign.
