W25Q16JWSSIM

Memory IC Overview

The W25Q16JWSSIM is a 16M-bit (2M x 8) Serial NOR Flash memory from Winbond Electronics, part of the SpiFlash series. It operates on a single 1.65V to 1.95V supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 133 MHz. The device features uniform 4KB sectors, 32KB blocks, and 64KB blocks for erasure, with page programming capabilities up to 256 bytes. It includes advanced security features such as hardware write protection, individual block/sector locks, and three 256-byte security registers. Packaged in an 8-SOIC format, it is designed for industrial applications with a wide operating temperature range.

Memory IC Feature Summary

• Provides flexible architecture with uniform 4KB sector erase capability suitable for parameter storage.
• Includes comprehensive write protection mechanisms via hardware pins and software-configurable status register bits.
• Features low power consumption with standby current below 0.1µA and wide temperature operation ranges.

Memory IC Applications

• Code shadowing to RAM
• Execute-in-place (XIP) applications
• Storage of voice, text, and data

Memory IC Procurement Notes

Verify the specific ordering suffix SSIM against the manufacturer's official datasheet to confirm package dimensions and pin compatibility. Confirm that the voltage supply requirements align with the 1.65V to 1.95V specification before integration. Check for any recent Product Change Notices regarding manufacturing sites or material composition updates.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is required with strict voltage constraints between 1.65V and 1.95V. Ensure the design supports Dual or Quad SPI protocols to utilize the full performance potential. Consider the 8-SOIC package size if space efficiency is a priority alongside industrial temperature stability.

Memory IC Part Context

This part belongs to the W25Q16JV family of Serial NOR Flash memories manufactured by Winbond Electronics. It shares core architectural similarities with other members of the 25Q series but is distinguished by its specific voltage range and industrial-grade specifications. The device is designed to replace older parallel flash solutions with a serial interface alternative.
