Product details
Overview
W25Q16DVSNJP 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 for code storage and execution in microcontroller boot loaders, IoT firmware, and embedded HMI systems.
For engineers reviewing the W25Q16DVSNJP datasheet, W25Q16DVSNJP pinout, W25Q16DVSNJP application, or W25Q16DVSNJP equivalent, key selection criteria include Quad SPI timing compliance, 4 KB sector erase granularity, hardware write protection via /WP and /HOLD pins, and SOIC-8 150-mil package compatibility with legacy PCB footprints.
Technical Context
The W25Q16DVSNJP 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 a 256-byte page buffer, 512 erasable 4 KB sectors, and dedicated security registers with OTP locks.
It supports JEDEC-standard manufacturer/device ID (90h/9Fh), SFDP register (5Ah) for discoverable parameters, and advanced features including erase/program suspend/resume (75h/7Ah), power-down (B9h), and 64-bit unique serial number (4Bh). All timing adheres to SPI Mode 0 and Mode 3, with AC characteristics validated at 2.7–3.6 V and –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes), organized as 8,192 × 256-byte pages |
| SPI Clock Frequency | Up to 104 MHz - enables 416 MHz effective throughput in Quad I/O mode using EBh instruction |
| Erase Granularity | Uniform 4 KB sectors (512 total), plus 32 KB and 64 KB block erase options - supports fine-grained firmware partitioning |
| Write Protection | Hardware /WP pin + software BP[2:0]/TB/SEC bits - allows selective locking of top/bottom 4 KB sectors or entire array |
| Power Supply | Single 2.7 V to 3.6 V supply; 4 mA typical active current, <1 µA power-down current - suitable for battery-backed systems |
| Data Retention | 20+ years at +25°C - verified per JEDEC JESD22-A117 standard |
| Endurance | 100,000 program/erase cycles per sector - sufficient for field-upgradable firmware with wear leveling |
Pinout & Package
W25Q16DVSNJP is packaged in an 8-pin SOIC 150-mil (package code SN), with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC footprint. Pin 1 is marked by a notch or dot; device orientation follows standard SOIC top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; required low-to-high transition before new instruction acceptance |
| 2 DO (IO1) | Serial Data Output / Bidirectional I/O1 | Unidirectional output in Standard/Dual SPI; bidirectional in Dual/Quad mode; used for Fast Read instructions |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Active-low hardware lock for Status Register; repurposed as IO2 when QE=1 (Quad mode enabled) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance connection to system ground plane |
| 5 DI (IO0) | Serial Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad mode; carries instructions, addresses, and data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transaction while /CS remains low; repurposed as IO3 when QE=1 |
| 8 VCC | Power Supply | 2.7–3.6 V nominal; bypass capacitor (0.1 µF ceramic) required within 5 mm of pin for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI XIP Support | Enables execute-in-place from flash via EBh/E7h instructions - eliminates RAM copy overhead for boot code and real-time firmware |
| Continuous Read Mode | As few as 8 clocks to initiate address access; supports wrap lengths of 8/16/32/64 bytes - reduces instruction overhead for streaming reads |
| Security Registers | Three 256-byte OTP-lockable security registers - usable for keys, calibration data, or secure boot manifests with hardware-enforced write protection |
| JEDEC SFDP Compliance | Read SFDP register (5Ah) returns vendor-defined parameter tables - enables automatic driver configuration without hard-coded timing values |
| Erase/Program Suspend | 75h/7Ah commands allow pausing long erase/program operations to service higher-priority interrupts - critical for deterministic real-time response |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM1I-12G | Same density (16 M-bit), SOIC-8 150-mil, but max SPI clock 80 MHz; no Quad I/O wrap modes or SFDP register | Lacks continuous read wrap and XIP-optimized Quad I/O - less suitable for high-throughput firmware streaming | Choose for cost-sensitive designs where 80 MHz SPI suffices and SFDP auto-configuration is unnecessary |
| S25FL116K0XMFI041 | 16 M-bit, SOIC-8, supports Quad SPI up to 104 MHz, but uses different status register layout and lacks security registers | No OTP-locked security registers or 64-bit UID - limits use in secure boot or device identity applications | Prefer when migrating from Spansion legacy platforms; verify status register bit mapping and erase command compatibility |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, W25Q16DVSNJP delivers superior XIP performance via continuous read wrap and Quad I/O, plus hardware-enforced security features essential for certified firmware storage - making it optimal for safety-critical and upgradable embedded systems.

FAQ
What is the package type and lead count of W25Q16DVSNJP?
W25Q16DVSNJP uses an 8-pin SOIC package with 150-mil body width (package code SN), featuring gull-wing leads and JEDEC MS-012AC footprint. It is not pin-compatible with 208-mil or PDIP variants due to pitch and dimension differences - board layout must match SN-specific land pattern.
Does W25Q16DVSNJP support Quad SPI mode out of the box?
No - W25Q16DVSNJP requires the Quad Enable (QE) bit in Status Register-2 to be set (via Write Status Register instruction 01h) before /WP and /HOLD pins become IO2 and IO3. Until QE=1, those pins retain hardware write protect and hold functions; default state is Standard SPI only.
How many program/erase cycles does W25Q16DVSNJP guarantee?
W25Q16DVSNJP guarantees a minimum of 100,000 program/erase cycles per sector, validated per JEDEC JESD22-A117. This endurance rating applies to each 4 KB sector individually, enabling wear leveling algorithms to extend effective lifetime beyond 1 million cycles in well-designed firmware partitions.
Can W25Q16DVSNJP be used for execute-in-place (XIP) applications?
Yes - W25Q16DVSNJP supports true XIP via Continuous Read Mode with Fast Read Quad I/O (EBh) and Word Read Quad I/O (E7h) instructions. With as few as 8 clocks to initiate address access and 416 MHz effective throughput, it enables deterministic code execution directly from flash without RAM buffering.
What is the purpose of the 64-bit Unique ID in W25Q16DVSNJP?
The 64-bit Unique ID (read via instruction 4Bh) provides a factory-programmed, unalterable device fingerprint used for secure boot binding, anti-cloning, and firmware licensing. Each W25Q16DVSNJP unit has a distinct value, enabling cryptographic key derivation and device-specific provisioning in trusted execution environments.
