Product details
Overview
W25Q16DVSFIG 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 XIP-capable continuous read mode - deployed in embedded boot code storage, firmware update partitions, and parameter retention in industrial microcontroller systems.
For engineers reviewing the W25Q16DVSFIG TR datasheet, W25Q16DVSFIG TR pinout, W25Q16DVSFIG TR application, or W25Q16DVSFIG TR equivalent, this page delivers verified pin functions, real-world timing performance (416 MHz Quad I/O equivalent), JEDEC-compliant identification, 64-bit unique ID, and hardware write protection logic for secure firmware storage design.
Technical Context
The W25Q16DVSFIG TR implements a SPI-compatible command-set architecture with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit (SR-2 bit 1) to be set. Its block diagram integrates a 256-byte page buffer, status register control logic, high-voltage generators for erase/program, and SFDP register for discoverable parameters.
It supports four erase granularities - 4 KB sector, 32 KB block, 64 KB block, and full chip - with up to 100,000 program/erase cycles and >20-year data retention. The /WP and /HOLD pins serve dual roles: dedicated hardware control in Standard/Dual mode, and bidirectional IO2/IO3 in Quad mode when QE=1.
Key Specifications

Pinout & Package
W25Q16DVSFIG TR is supplied in an 8-pin SOIC 208-mil package (package code SS), with gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO/IOx to high-Z when high; required low-to-high transition after power-up to accept commands |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes IO1 in Dual/Quad mode - used for read data and status feedback |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for Status Register when QE=0; repurposed as IO2 in Quad mode (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals - must be low-impedance and decoupled near device |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes IO0 in Dual/Quad mode - carries instructions, addresses, and write data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI operations - supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write while /CS is low; repurposed as IO3 in Quad mode (QE=1) |
| 8 VCC | Power Supply | 2.7–3.6 V main supply - requires local 0.1 µF ceramic decoupling capacitor between VCC and GND |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI XIP Support | Enables true execute-in-place from flash via Fast Read Quad I/O (EBh) with ≤8-clock address overhead - eliminates RAM copy latency for boot code |
| Erase/Program Suspend | Allows interrupting long erase/program cycles (e.g., 400 ms sector erase) to service time-critical reads - critical for real-time firmware updates |
| Security Registers | Three 256-byte OTP-lockable security registers - store cryptographic keys or calibration data immune to accidental overwrite |
| SFDP Compliance | JEDEC JESD216-compliant Serial Flash Discoverable Parameters register - enables automatic driver configuration without hard-coded timing values |
| Continuous Read Mode | Configurable 8/16/32/64-byte wrap - reduces instruction overhead per access and sustains >52 MB/s sequential throughput |
| Top/Bottom Block Protection | Hardware + software control (TB bit + BPx) to lock either end of memory array - isolates bootloader region from application firmware corruption |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM2I-12G | Same density (16 M-bit), 3.3 V, but max SPI clock 80 MHz; no Quad I/O suspend/resume; lacks SFDP and 64-bit UID | Lower throughput limits XIP performance; no built-in security registers - requires external key management | Choose for cost-sensitive designs where 52 MB/s throughput and OTP security are not required |
| S25FL116K0XMFI041 | 16 M-bit, 3.0 V min, supports QPI mode and 133 MHz clock; includes 128-byte security register (not OTP); no Erase Suspend | Higher clock enables faster bulk reads, but lacks suspend/resume for real-time systems; no 64-bit UID | Prefer when maximum sequential speed is prioritized over deterministic interruptible erase cycles |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, the W25Q16DVSFIG TR uniquely combines Quad I/O suspend/resume, 64-bit UID, SFDP, and OTP security registers - making it optimal for secure, real-time, XIP-based embedded firmware where deterministic operation and device identity are mandatory.

FAQ
What is the maximum SPI clock frequency supported by the W25Q16DVSFIG TR?
The W25Q16DVSFIG TR supports up to 104 MHz SPI clock frequency in Standard, Dual, and Quad SPI modes. In Quad I/O mode using Fast Read Quad I/O (EBh), this yields an effective data rate of 416 MHz (104 MHz × 4), enabling sustained 52 MB/s continuous read throughput - confirmed in Section 8.6 of the official datasheet.
Does the W25Q16DVSFIG TR support execute-in-place (XIP) operation?
Yes, the W25Q16DVSFIG TR supports true XIP via its Continuous Read Mode and Fast Read Quad I/O (EBh) instruction, requiring only 8 clocks to address memory and sustaining high bandwidth - allowing microcontrollers to execute code directly from flash without RAM loading, as detailed in Sections 1 and 6.1.3.
How is hardware write protection implemented on the W25Q16DVSFIG TR?
Hardware write protection on the W25Q16DVSFIG TR uses the /WP pin in conjunction with Status Register bits BP2–BP0, TB, and SRP0/SRP1. When /WP is pulled low and BP bits are set, specific 4 KB sectors (or top/bottom array) become read-only - independent of software commands, as defined in Sections 4.3 and 7.1.3–7.1.7.
What package type does the W25Q16DVSFIG TR use, and what is its lead pitch?
The W25Q16DVSFIG TR uses an 8-pin SOIC 208-mil package (package code SS) with 1.27 mm lead pitch, gull-wing leads, and RoHS-compliant matte tin plating - documented in Section 9.2 and Table 10.1 of the datasheet, and verified via Winbond's official ordering information.
Can the W25Q16DVSFIG TR suspend an ongoing erase or program operation?
Yes, the W25Q16DVSFIG TR supports Erase/Program Suspend (75h) and Resume (7Ah) instructions, allowing interruption of long-duration operations (e.g., 400 ms sector erase) to service urgent read requests - a feature critical for real-time embedded systems, as specified in Sections 7.2.27–7.2.28.
