W25Q16DVSSJG TR

Memory IC Overview

The W25Q16DVSSJG TR is a 16M-bit (2M-byte) Serial Flash memory device 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 104MHz. The memory array consists of 8,192 programmable pages of 256 bytes each, organized into uniform 4KB sectors and 32/64KB blocks. The component is housed in an 8-pin SOIC package and is supplied in tape and reel packaging.

Memory IC Feature Summary

• Supports high-performance Dual and Quad SPI operations for efficient code execution directly from memory.
• Provides flexible write protection mechanisms including hardware control via the /WP pin and software-based sector/block locking.
• Integrates advanced security features such as a 64-bit unique serial number and three 256-byte security registers with OTP locks.

Memory IC Applications

• Code shadowing to RAM for embedded systems
• Executing code directly from SPI bus (XIP)
• Storing voice, text, and data parameters

Memory IC Procurement Notes

Verify the specific ordering suffix 'TR' corresponds to the Tape and Reel packaging format required for automated assembly processes. Confirm that the 'SS' designation aligns with the intended 8-pin SOIC physical dimensions and thermal characteristics for the target PCB layout. Ensure compatibility with the specified voltage range and interface protocols during system integration.

Memory IC Selection Notes

Select this component for applications requiring space-efficient storage with support for high-speed data transfer via Quad SPI modes. Consider its wide operating temperature range and low power consumption characteristics for portable or industrial environments. Evaluate the need for hardware write protection and unique identification features when designing secure embedded architectures.

Memory IC Part Context

This part belongs to the W25Q series of SpiFlash memories, designed to offer flexibility and performance beyond ordinary serial flash devices. The W25Q16DV variant specifically targets systems with limited space, pins, and power constraints while providing robust data retention and endurance specifications suitable for frequent update cycles.

Memory IC FAQ

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

When the non-volatile Quad Enable bit in Status Register-2 is set, the /WP pin functions as IO2 and the /HOLD pin functions as IO3 to support Quad SPI instructions.

What erase granularity options are available?

The device allows erasing in groups of 16 pages (4KB sector erase), groups of 128 pages (32KB block erase), groups of 256 pages (64KB block erase), or the entire chip.
