W25X10VSNIG T&R

Memory IC Overview

The W25X10VSNIG T&R is a 1M-bit (128K-byte) serial flash memory from the Winbond W25X series. It operates on a single 2.7V to 3.6V supply and supports SPI clock frequencies up to 75MHz, enabling data transfer rates of up to 150M-bits/second via Fast Read Dual Output. The device features uniform 4KB sectors and 64KB blocks, with page programming capabilities for up to 256 bytes in under 2ms. It is housed in an 8-pin SOIC package and includes hardware and software write protection mechanisms.

Memory IC Feature Summary

• Supports standard SPI and high-performance dual output SPI modes for flexible data access.
• Features flexible architecture with uniform 4KB sectors and 64KB blocks for efficient storage management.
• Includes comprehensive write protection options utilizing both hardware pins and software status register controls.

Memory IC Applications

• Code download applications requiring code-shadowing or caching to RAM.
• Storage of voice, text, and parameter data in space-constrained systems.
• Embedded systems needing non-volatile memory with low power consumption.

Memory IC Procurement Notes

Verify that the ordering suffix 'T&R' corresponds to the Tape & Reel packaging format as specified by the manufacturer. Confirm the package type matches the required 8-pin SOIC dimensions. Ensure compatibility with the 2.7V to 3.6V operating voltage range and check for any specific environmental certifications required for the target application.

Memory IC Selection Notes

Select this component when a 1M-bit capacity is sufficient for the system requirements. Consider the W25X series if dual output SPI performance is needed to match parallel flash speeds. Evaluate the 8-pin SOIC package against available board space constraints. Verify that the -40°C to +85°C operating temperature range meets the environmental conditions of the deployment site.

Memory IC FAQ

What is the maximum clock frequency supported by the W25X10?

The device supports SPI clock frequencies of up to 75MHz.

How does the Hold function operate?

The /HOLD pin allows the device operation to be paused while actively selected, placing the DO pin in high impedance and ignoring DIO and CLK signals until the hold condition is released.
