W25Q16DVSFIG TR

Memory IC Overview

The W25Q16DV is a 16M-bit (2M-byte) Serial Flash memory from Winbond Electronics, designed for systems with limited space and power. It operates on a single 2.7V to 3.6V supply, drawing 4mA active current and less than 1µA in power-down mode. The device supports SPI clock frequencies up to 104MHz, enabling equivalent rates of 208MHz for Dual I/O and 416MHz for Quad I/O. It features an array organized into 8,192 pages of 256 bytes each, supporting uniform sector, block, and chip erase operations.

Memory IC Procurement Notes

Verify the specific package variant required, as the W25Q16DV series includes multiple options such as SOIC, WSON, USON, PDIP, WLCSP, SOIC-16, and TFBGA. Confirm that the ordering suffix matches the desired physical footprint and pin configuration. Ensure compatibility with the target system's voltage levels and interface requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a balance of storage capacity and high-speed performance is needed in a compact form factor. It is suitable for applications requiring flexible erase architectures and robust security features. Consider the available package types to match board space constraints. Verify that the host controller supports the necessary SPI modes, including Dual or Quad I/O if maximum throughput is required.

Memory IC Part Context

The W25Q16DV belongs to the W25Q series of SpiFlash memories, which are known for their flexibility and performance beyond ordinary serial flash devices. This series is widely used in consumer electronics, industrial controls, and IoT applications where reliable non-volatile storage is essential. Winbond Electronics manufactures these devices using advanced semiconductor processes to ensure high reliability and longevity.

Memory IC Replacement Considerations

Compatible substitutes include other models within the W25Q family, such as the W25Q16BV or W25Q16J, provided they support the same voltage range and interface protocols. Ensure that any replacement part maintains pin compatibility and electrical characteristics similar to the original specification.
