W25Q256JVEIQ TR

Memory IC Overview

The W25Q256JVEIQ TR is a 256M-bit (32M x 8) NOR flash memory from Winbond's SpiFlash series, housed in an 8-WSON package. It operates on a single 2.7V to 3.6V supply with a maximum clock frequency of 133 MHz. The device supports standard, dual, and quad SPI interfaces for data transfer. It features uniform sector and block erase capabilities, including 4KB sectors, 32KB blocks, and 64KB blocks. The memory array consists of 131,072 programmable pages of 256 bytes each.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI operations with up to 133MHz clock frequencies.
• Features flexible architecture with 4KB uniform sectors for efficient data storage.
• Includes advanced security functions such as hardware write protection and OTP locks.
• Provides execute-in-place (XIP) capability via Quad Peripheral Interface.

Memory IC Applications

• Code shadowing to RAM
• Executing code directly from Dual/Quad SPI (XIP)
• Storing voice, text, and data

Memory IC Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging when sourcing components. Confirm that the voltage range matches system requirements, as this model operates between 2.7V and 3.6V. Ensure compatibility with the 8-WSON package dimensions for PCB layout. Check for moisture sensitivity level requirements during storage and handling procedures.

Memory IC Selection Notes

Select this component for applications requiring high-density non-volatile storage in space-constrained designs. The 256M-bit capacity suits systems needing extensive firmware or data retention. Consider the 133MHz speed for high-performance data access needs. Verify that the host controller supports the required SPI modes, particularly if utilizing quad I/O operations for enhanced throughput.

Memory IC Part Context

This part belongs to the W25Q256JV series of serial flash memories designed for systems with limited pins and power. It offers performance exceeding ordinary serial flash devices through dual and quad SPI support. The series is engineered for reliability, featuring robust write protection mechanisms and long data retention characteristics suitable for industrial and consumer electronics.

Memory IC FAQ

What are the available address modes for the W25Q256JVEIQ?

The device supports both 3-Byte and 4-Byte Address Modes. The mode can be selected upon power-up via the ADP bit or switched dynamically using specific instructions.

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit in Status Register-2 is set, the /WP pin functions as IO2 and the /HOLD pin functions as IO3, enabling full Quad SPI operation.
