Product details
Overview
W25Q16FWSNIQ TR from Winbond is a 1.8V, 16M-bit serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, organized as 8192 × 256-byte pages with 4KB uniform sectors, 32KB/64KB blocks, and 100K program-erase cycles - deployed for XIP code execution, firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q16FWSNIQ TR datasheet, W25Q16FWSNIQ TR pinout, W25Q16FWSNIQ TR application, or W25Q16FWSNIQ TR equivalent, key selection criteria include 104MHz SPI clock support, quad I/O enable (QE bit), hardware /WP and /HOLD control, 1.65–1.95V supply range, and SOIC-8 (150-mil) package compatibility with industrial temperature operation.
Technical Context
The W25Q16FWSNIQ TR implements a flexible SPI-compatible interface with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (2-clock instruction fetch). Its architecture supports true execute-in-place (XIP) via Continuous Read Mode with ≤8-clock address overhead and wrap lengths of 8/16/32/64 bytes.
Functional control relies on volatile and non-volatile status register bits including Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom protect (TB), Security Register Lock (LB[3:1]), and Output Driver Strength (DRV1/DRV0), enabling fine-grained memory protection and performance tuning without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM2I-12G | 3V supply (2.7–3.6V); no QPI mode; 86 MHz max SPI clock; lacks security registers and SFDP | Requires level-shifting for 1.8V systems; unsuitable for secure boot or high-bandwidth XIP | Select only for legacy 3V designs where cost outweighs performance and security needs |
| S25FL116K0XMFI041 | 1.8V supply; 133 MHz SPI; HyperBus interface option; no /HOLD pin; different status register layout | Higher bandwidth but incompatible pinout and command set; no hardware /WP or /HOLD fallback | Prefer for new designs needing >50 MB/s throughput, but verify full software stack compatibility |
Compared with W25Q16FWSNIQ TR, MX25L1606EM2I-12G trades voltage compatibility and advanced features for lower cost in 3V systems, while S25FL116K0XMFI041 offers higher speed and alternate interfaces at the expense of pin and command compatibility - making W25Q16FWSNIQ TR optimal for balanced 1.8V industrial XIP deployments.

FAQ
What is the operating voltage range for the W25Q16FWSNIQ TR?
The W25Q16FWSNIQ TR operates from 1.65 V to 1.95 V. This narrow 1.8V nominal range ensures compatibility with modern low-power microcontrollers and eliminates the need for external level shifters in 1.8V system designs. Operation outside this range may cause unreliable read/write behavior or permanent damage. The device draws only 4 mA during active read operations and less than 1 µA in power-down mode, supporting energy-sensitive applications.
Does the W25Q16FWSNIQ TR support execute-in-place (XIP) functionality?
Yes, the W25Q16FWSNIQ TR supports true XIP through its Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clock cycles to address memory and up to 416 MHz effective bandwidth in Quad I/O mode, it enables deterministic instruction fetch directly from flash. The 4KB uniform sector architecture further allows safe in-field firmware updates without disrupting running code - a key requirement for W25Q16FWSNIQ TR deployments in real-time embedded systems.
How is Quad SPI mode enabled on the W25Q16FWSNIQ TR?
Quad SPI mode on the W25Q16FWSNIQ TR is enabled by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register-2 (31h) instruction. When QE = 1, pins /WP and /HOLD become IO2 and IO3 respectively, completing the 4-bit I/O bus. This configuration is non-volatile unless cleared, and must be verified before issuing Quad I/O commands like Fast Read Quad I/O (EBh). The W25Q16FWSNIQ TR datasheet specifies that QE defaults to 0 after power-up.
What package type does the W25Q16FWSNIQ TR use?
The W25Q16FWSNIQ TR uses an 8-pin SOIC-150-mil package (Package Code SN), with standard JEDEC MS-012 dimensions and lead finish. This surface-mount package supports automated assembly and is compatible with IPC-7351B footprint guidelines. Pin 1 is identified by a notch or dot, and the package is rated for industrial temperature operation (−40°C to +85°C), making it suitable for W25Q16FWSNIQ TR use in harsh environmental conditions without derating.
Can the W25Q16FWSNIQ TR be used with a 3.3V microcontroller SPI interface?
No - the W25Q16FWSNIQ TR is strictly a 1.65–1.95V device and is not 3.3V-tolerant. Direct connection to a 3.3V SPI master will damage the W25Q16FWSNIQ TR inputs. A bidirectional level shifter compliant with 1.8V/3.3V translation (e.g., TXS0108E) is required for interoperability. Alternatively, select a 3.3V-compatible flash such as the W25Q16DW, which shares instruction compatibility but uses different voltage and timing specifications.
