W25Q64JVSFJM

Memory IC Overview

The W25Q64JVSFJM is a 64M-bit (8M x 8) Serial NOR Flash memory from Winbond, designed for systems with limited space and power. It supports Standard SPI, Dual/Quad I/O SPI, QPI, and Double Transfer Rate (DTR) read operations at clock frequencies up to 133 MHz. The device operates on a single 2.7V to 3.6V supply and features a flexible architecture with uniform 4KB sectors and 32KB/64KB blocks. It includes advanced security features such as hardware write protection, OTP locks, and individual block protection.

Memory IC Feature Summary

• Supports DTR read instructions for high-speed data transfer alongside standard, dual, and quad SPI modes.
• Features a dedicated hardware /RESET pin available on the 16-pin SOIC package for system reset control.
• Provides comprehensive write protection mechanisms including top/bottom array protection and sector-level locking.
• Includes a 64-bit unique serial number and SFDP registers for device identification and parameter discovery.

Memory IC Applications

• Industrial embedded systems requiring code execution in place (XIP)
• IoT devices needing secure firmware storage with hardware reset capabilities
• Communication modules storing configuration parameters and logs
• Consumer electronics utilizing compact 16-pin packaging for board space optimization

Memory IC Procurement Notes

Verify the specific suffix 'SFJM' against the manufacturer's official ordering information to confirm the exact package type and temperature grade. Ensure compatibility with the 16-pin SOIC footprint if the design requires the dedicated hardware reset pin functionality described in the datasheet.

Memory IC Selection Notes

Select this component when a dedicated hardware reset pin is required within an 8-pin equivalent form factor constraint or when utilizing the 16-pin SOIC variant. Consider the DTR capability for applications demanding higher throughput than standard Quad SPI can provide without increasing pin count.

Memory IC Part Context

This part belongs to the W25Q64JV series, which offers industrial and industrial plus temperature grades. The 'SF' suffix typically denotes the 16-pin SOIC package, distinguishing it from the more common 8-pin variants like SS or ZP. This series is engineered for high performance and reliability in space-constrained environments.

Memory IC Replacement Considerations

W25Q64JVSFIM: Identical electrical specifications but lacks the DTR feature set.

Memory IC FAQ

Does the W25Q64JVSFJM support Double Transfer Rate (DTR)?

Yes, the W25Q64JV series supports DTR read instructions, allowing data transfer rates that exceed standard Quad SPI speeds by utilizing both edges of the clock signal.

What is the function of the /RESET pin on this package?

On the 16-pin SOIC package, the /RESET pin provides a dedicated hardware reset function that is independent of the QE bit setting and other status register configurations.
