Product details
Overview
W25Q16DVSNIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz clock capability, 4 KB uniform sector architecture, and hardware write protection via /WP and /HOLD pins - used for code storage, XIP execution, and firmware parameter retention in microcontroller boot loaders and IoT edge nodes.
For engineers reviewing the W25Q16DVSNIG TR datasheet, W25Q16DVSNIG TR pinout, W25Q16DVSNIG TR application, or W25Q16DVSNIG TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector erase granularity, 2.7–3.6 V single-supply operation, and SOIC-8 150-mil package compatibility with legacy PCB footprints.
Technical Context
The W25Q16DVSNIG TR implements a SPI-compatible command set with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit (SR2[1]) to be set. Its internal architecture includes an 8,192-page × 256-byte array, 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks.
It supports JEDEC-standard identification (9Fh), SFDP register (5Ah), 64-bit unique ID (4Bh), and security registers with OTP locks. Erase/program suspend/resume (75h/7Ah) enables concurrent background operations, while continuous read mode reduces instruction overhead to 8 clocks per address access - enabling true execute-in-place (XIP) functionality.

Pinout & Package
W25Q16DVSNIG TR uses an 8-pin SOIC-150-mil (package code SN) with standard SPI pinout and dual/quad I/O multiplexing. Pin functions are fixed per physical position and support hardware write protect (/WP) and hold (/HOLD) control independent of SPI mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO output when deasserted; required low-to-high transition before new instruction acceptance |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard/Dual SPI; bidirectional I/O in Quad SPI; used for status/data reads on CLK falling edge |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for Status Register writes; disabled as /WP when QE=1 (Quad mode active); active-low function |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable timing and noise immunity |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard/Dual SPI; bidirectional I/O in Quad SPI; accepts instructions/addresses/data on CLK rising edge |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing SPI transfer without deselecting device; disabled as /HOLD when QE=1; active-low with internal pull-up |
| 8 VCC | Power Supply | 2.7–3.6 V nominal; powers core logic, charge pumps, and I/O buffers; requires local 0.1 µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit [1] enables IO2/IO3 mapping for 4-line data transfer - essential for ≥400 MB/s burst reads |

| 4 KB Uniform Sector Architecture | Allows fine-grained firmware updates and parameter storage without erasing unrelated code regions - critical for OTA reliability |
| Erase/Program Suspend | 75h/7Ah commands pause background erase/program to service urgent read requests - avoids latency spikes in real-time systems |
| 64-bit Unique Serial Number | Factory-programmed per-device ID accessible via 4Bh instruction - enables secure device binding and anti-cloning in certified applications |

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 |
|---|---|---|---|
| MX25L1606EZN-12G | Same density (16 M-bit), SOIC-8, but max SPI clock 80 MHz; no Quad I/O; lacks SFDP and unique ID | Limited to Standard/Dual SPI; unsuitable for XIP or high-throughput OTA; no standardized parameter discovery | Select when cost sensitivity outweighs performance and security needs; verify /WP and /HOLD behavior matches legacy design. |
| S25FL116K0XMFI011 | 16 M-bit, SOIC-8, supports Quad SPI up to 104 MHz, includes SFDP and 64-bit ID, but requires VIO pin (1.65–3.6 V) separate from VCC | Needs additional voltage rail routing; supports QPI mode not available on W25Q16DVSNIG TR | Choose for Cypress/Fujitsu ecosystem compatibility; confirm board layout accommodates VIO decoupling and level-shifting. |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI011, the W25Q16DVSNIG TR delivers identical package fit and Quad SPI performance while offering superior security (OTP security registers, CMP bit), simpler power architecture (single VCC), and broader instruction set coverage including Octal Word Read and Set Burst with Wrap.

FAQ
What is the maximum SPI clock frequency supported by the W25Q16DVSNIG TR?
The W25Q16DVSNIG TR supports up to 104 MHz for Standard and Dual SPI operations, and up to 104 MHz for Quad SPI clock input - enabling effective data rates of 208 Mbps (Dual) and 416 Mbps (Quad) using Fast Read Dual/Quad I/O instructions. This is confirmed in Section 1. GENERAL DESCRIPTION and Table 8.6 AC Electrical Characteristics of the datasheet.
Does the W25Q16DVSNIG TR support execute-in-place (XIP) operation?
Yes, the W25Q16DVSNIG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to just 8 clock cycles per 24-bit address access. When combined with Quad SPI Fast Read instructions (e.g., EBh), it enables deterministic code execution directly from flash without shadowing to RAM - a capability explicitly stated in Section 1 and Section 2 FEATURES.
How is Quad SPI mode enabled on the W25Q16DVSNIG TR?
Quad SPI mode on the W25Q16DVSNIG TR is enabled by setting the non-volatile Quad Enable (QE) bit - bit [1] of Status Register-2 - using the Write Status Register (01h) instruction. Once QE = 1, pins /WP and /HOLD become IO2 and IO3 respectively, allowing full 4-line bidirectional data transfer. This requirement is documented in Sections 4.2, 6.1.3, and 7.1.10.
What package type does the W25Q16DVSNIG TR use, and is it pin-compatible with other W25Q16 variants?
The W25Q16DVSNIG TR uses an 8-pin SOIC-150-mil package (package code SN), matching the pinout of W25Q16DVSSIG and W25Q16DVSFIG. All share identical /CS, DO, /WP, GND, DI, CLK, /HOLD, and VCC assignments per Figure 1a - making them mechanically and electrically interchangeable in SOIC-150 footprints without PCB changes.
Does the W25Q16DVSNIG TR include hardware write protection beyond software-based status register locking?
Yes, the W25Q16DVSNIG TR provides dual-layer write protection: hardware-level via the active-low /WP pin (which locks Status Register writes when asserted), and software-level via Block Protect (BP2–BP0), Top/Bottom (TB), and Status Register Protect (SRP0/SRP1) bits. The /WP pin remains functional unless Quad SPI mode is enabled (QE = 1), as specified in Sections 4.3 and 6.2.1.
