W25Q16BVSFIG

Memory IC Overview

The W25Q16BVSFIG is a 16M-bit (2M-byte) serial NOR flash memory from Winbond Electronics, organized into 8,192 programmable pages of 256 bytes each. It supports standard SPI, Dual SPI, and Quad SPI interfaces with clock frequencies up to 104MHz, enabling equivalent rates of 208MHz for Dual Output and 416MHz for Quad Output. The device operates on a single 2.7V to 3.6V supply, drawing 4mA active current and less than 1µA in power-down mode. It features uniform 4KB sectors and 32KB/64KB blocks, offering more than 100,000 erase/write cycles and over 20-year data retention.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes for high-speed data transfer and Execute-In-Place (XIP) operations.
• Includes hardware write protection via the /WP pin and software protection through configurable status register bits.
• Features a hold function that pauses device operation without deselecting, useful for shared bus environments.
• Provides advanced security with lock-down and OTP protection options alongside a unique 64-bit serial number.

Memory IC Applications

• Code shadowing to RAM for microcontroller systems
• Direct code execution from Dual/Quad SPI (XIP)
• Storage of voice, text, and data parameters

Memory IC Procurement Notes

Verify the specific suffix 'F' against the manufacturer's official ordering information to confirm package type and temperature grade. Ensure compatibility with the host system's voltage levels and SPI interface modes before integration. Cross-reference the JEDEC ID and unique serial number requirements if device authentication is necessary for the application.

Memory IC Selection Notes

Select this component when space, pins, and power are limited but high performance is required. It is suitable for applications needing flexible architecture with small sector sizes for parameter storage. Consider the 16-pin SOIC option if additional pin isolation or specific layout constraints exist compared to the 8-pin variants.

Memory IC Part Context

This part belongs to the W25Q series of SpiFlash memories, designed for systems with constrained resources. It offers flexibility and performance exceeding ordinary serial flash devices. The series supports various packages including SOIC and WSON to accommodate different board space requirements while maintaining electrical compatibility across capacity ranges.

Memory IC Replacement Considerations

Check for W25Q16BVSSIG or W25Q16BVDAIG as potential physical replacements depending on the required package width (208-mil vs 150-mil SOIC). Verify that any substitute maintains the same 16M-bit capacity and 2.7V-3.6V operating voltage range.
