W25Q16JVSNIQ

Memory IC Overview

The W25Q16JVSNIQ is a 16M-bit (2M-byte) Serial NOR Flash memory manufactured by Winbond Electronics. It operates on a single 2.7V to 3.6V power supply and supports standard, dual, and quad SPI interfaces with clock frequencies up to 133MHz. The device features uniform 4KB sectors and 32/64KB blocks for flexible erasure, along with advanced security registers and hardware write protection. It is housed in an 8-pin SOIC package.

Memory IC Feature Summary

• Supports high-speed data transfer via Dual and Quad SPI modes with up to 133MHz clock frequency.
• Includes comprehensive hardware and software write protection mechanisms with individual block locking capabilities.
• Enables direct code execution from the flash memory through XIP (Execute In Place) functionality.
• Integrates three 256-byte security registers with OTP locks and a unique 64-bit serial number.

Memory IC Applications

• Code shadowing to RAM
• Direct code execution (XIP)
• Storage of voice, text, and data

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Ensure that any required configuration bits, such as the Quad Enable bit, are correctly set within the status register before initiating Quad SPI operations.

Memory IC Selection Notes

Select this component for applications requiring space-efficient storage solutions with robust data integrity features. It is suitable for systems needing reliable non-volatile memory with flexible sector sizes and secure data handling capabilities.

Memory IC Part Context

This part belongs to the W25Q16JV series of SpiFlash memories. It shares architectural similarities with other members of the family but is distinguished by its specific 16M-bit capacity and 8-pin SOIC packaging configuration.
