W25Q256JVEIQ

Memory IC Overview

The W25Q256JVEIQ is a 256M-bit (32M x 8) NOR flash memory from Winbond's SpiFlash series. It operates on a single 2.7V to 3.6V supply and supports standard, dual, and quad SPI interfaces with clock frequencies up to 133MHz. The device features uniform 4KB sector, 32KB block, and 64KB block erase capabilities. It includes advanced security features such as hardware write protection, OTP locks, and a unique 64-bit serial number. The component is housed in an 8-pad WSON 8x6-mm package.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI operations for high-speed data transfer
• Provides flexible architecture with uniform 4KB sectors for efficient data management
• Includes advanced security mechanisms like hardware write protection and OTP locks
• Features low power consumption with standby current below 1µA

Memory IC Applications

• Code shadowing to RAM
• Execute In Place (XIP) via Dual/Quad SPI
• Storage of voice, text, and data in space-constrained systems

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements of 2.7V to 3.6V. Confirm moisture sensitivity level handling during assembly. Check for RoHS compliance status relevant to your region. Validate pin configuration matches the 8-pad WSON footprint.

Memory IC Selection Notes

Select this component for applications requiring high-density non-volatile storage with fast read speeds. Consider the 4KB sector size for granular data updates. Evaluate the need for Quad SPI support to maximize throughput. Ensure the design accommodates the 8-pin WSON package constraints. Verify that the operating temperature range meets environmental specifications.

Memory IC Part Context

This part belongs to the W25Q256JV family of serial flash memories designed for systems with limited space and pins. It offers performance exceeding ordinary serial flash devices. The series supports JEDEC standard IDs and SFDP registers. It is suitable for embedded systems needing reliable code execution and data storage.

Memory IC Replacement Considerations

Check for direct substitutes within the W25Q256JV series with different package codes or suffixes. Verify electrical and pinout compatibility before substitution. Consult manufacturer guidelines for cross-referencing alternatives.
