Product details
Overview
W25Q16DVSSJP 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-ready continuous read mode. It operates from 2.7–3.6 V, draws 4 mA active current and <1 µA in power-down, and targets embedded code storage, firmware boot, and parameter retention in space-constrained MCU systems.
For engineers reviewing the W25Q16DVSSJP datasheet, W25Q16DVSSJP pinout, W25Q16DVSSJP application, or W25Q16DVSSJP equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector granularity for fine-grained updates, hardware write protection via /WP and /HOLD pins, and compatibility with SPI Mode 0/3 timing requirements in industrial temperature range (−40°C to +85°C).
Technical Context
The W25Q16DVSSJP implements a unified SPI command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD only after setting the non-volatile Quad Enable (QE) bit in Status Register-2. Its block diagram integrates a 256-byte page buffer, 512 × 4 KB sectors, and 32 × 64 KB blocks with independent erase control.
It supports JEDEC-standard manufacturer/device ID (90h/9Fh), 64-bit unique serial number (4Bh), SFDP register (5Ah), and three 256-byte security registers with OTP locks. Erase/program suspend/resume (75h/7Ah) enables concurrent background operations, while continuous read mode reduces instruction overhead to just 8 clocks per 24-bit address access.
Key Specifications

Pinout & Package
W25Q16DVSSJP is packaged in an 8-pin SOIC 208-mil (package code SS), with pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD (IO3), pin 8 = VCC. All pins support standard SPI; /WP and /HOLD become IO2/IO3 only when QE=1 for Quad SPI operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select input | Active-low enable: high = device deselected (high-Z outputs, standby current); low = active communication window |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional data lane 1 in Dual/Quad SPI |
| /WP / IO2 (Pin 3) | Write Protect input / Bidirectional I/O | Hardware lock for status register writes; repurposed as IO2 only when QE=1 |
| GND (Pin 4) | Ground reference | Primary return path for VCC and all I/O signals; must be low-impedance for noise immunity |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional data lane 0 in Dual/Quad SPI |
| CLK (Pin 6) | Serial clock input | Edge-triggered timing source: rising edge for input, falling edge for output in all SPI modes |
| /HOLD / IO3 (Pin 7) | Hold input / Bidirectional I/O | Pauses ongoing SPI transaction; repurposed as IO3 only when QE=1 |
| VCC (Pin 8) | Power supply | Single 2.7–3.6 V rail; requires local 0.1 µF decoupling capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit enabling 4-line I/O for 4× bandwidth boost - requires explicit write before use |
| Continuous Read Mode | 8-clock address overhead enables true XIP execution - eliminates repeated instruction fetches during linear code reads |
| 4 KB Uniform Sector Architecture | 512 individually erasable sectors allow precise firmware patching and parameter storage without disturbing adjacent data |
| Erase/Program Suspend & Resume | 75h/7Ah commands pause background erase/program to service urgent reads - critical for real-time interrupt latency control |
| 64-bit Unique Serial Number | Factory-programmed per-device ID (4Bh) supports secure device binding and anti-cloning in IoT endpoints |
| Security Registers | Three 256-byte OTP-lockable registers (42h/44h/48h) for keys, certificates, or calibration data - resistant to field reprogramming |
Applications
| Industrial PLC Firmware Storage | Automotive Infotainment Boot Memory |

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 | Same density (16 M-bit), 104 MHz max clock, but uses different QE implementation and lacks SFDP register | No built-in SFDP - requires hardcoded timing parameters; no 64-bit UID | Choose if legacy SPI controller lacks SFDP parsing and UID is unnecessary |
| S25FL116K0XMFI041 | 16 M-bit, 85 MHz max clock, supports Octal DTR mode (not supported by W25Q16DVSSJP), different security register layout | Lower max throughput; includes hardware ECC but no erase/program suspend | Prefer when system requires error correction for extended reliability in harsh EMI environments |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, W25Q16DVSSJP delivers higher Quad SPI bandwidth (416 MB/s vs. ≤340 MB/s), integrated SFDP for auto-configuration, and erase/program suspend for real-time responsiveness - making it optimal for XIP-capable, update-intensive embedded systems.

FAQ
What is the package type of W25Q16DVSSJP?
W25Q16DVSSJP uses an 8-pin SOIC 208-mil package (package code SS), with standard pinout: /CS (1), DO/IO1 (2), /WP/IO2 (3), GND (4), DI/IO0 (5), CLK (6), /HOLD/IO3 (7), VCC (8). This package is RoHS-compliant and compatible with standard surface-mount reflow profiles.
Does W25Q16DVSSJP support execute-in-place (XIP) operation?
Yes, W25Q16DVSSJP supports true XIP via its Continuous Read Mode, which reduces instruction overhead to just 8 clocks per 24-bit address. When used with Quad SPI (QE=1) and Fast Read Quad I/O (EBh), it delivers sufficient bandwidth for direct code execution from flash on Cortex-M and RISC-V MCUs without intermediate RAM loading.
How is Quad SPI enabled on W25Q16DVSSJP?
Quad SPI is enabled on W25Q16DVSSJP by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively - this change persists across power cycles and requires no reconfiguration.
What write protection mechanisms does W25Q16DVSSJP offer?
W25Q16DVSSJP provides dual-layer write protection: hardware-level via the /WP pin (active-low, disables status register writes), and software-level via Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Status Register Protect (SRP0/SRP1) bits. These can be combined to protect any 4 KB sector or larger region independently.
Is W25Q16DVSSJP suitable for automotive applications?
W25Q16DVSSJP is rated for −40°C to +85°C operation and meets industrial reliability standards (100,000 erase/program cycles, 20-year data retention), but it is not AEC-Q100 qualified. For automotive applications requiring qualification, Winbond offers the automotive-grade W25Q16JW variant - W25Q16DVSSJP is appropriate for under-dash infotainment or body-control modules where full AEC-Q100 is not mandated.
