Product details
Overview
W25Q16DVUUJP 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 rate, 4 KB uniform sector erase, and XIP-capable continuous read mode - used for code storage, firmware boot, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q16DVUUJP datasheet, W25Q16DVUUJP pinout, W25Q16DVUUJP application, or W25Q16DVUUJP equivalent, key selection considerations include Quad SPI enable (QE bit), 4 KB sector granularity, hardware write protection via /WP and /HOLD pins, and USON 4×3-mm package compatibility with space-constrained PCB layouts.
Technical Context
The W25Q16DVUUJP 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 setting in Status Register-2. It supports SPI modes 0 and 3, with hold/resume functionality enabled via active-low /HOLD pin during active /CS.
Internally, it features an 8,192-page × 256-byte array organized into 512 erasable 4 KB sectors and 32 erasable 64 KB blocks, with programmable block protection (BP2–BP0), top/bottom lock (TB), and security register locking (LB1–LB3) - all managed through dedicated status register bits and instruction set (e.g., 01h, 35h, EBh).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes), enabling full firmware image storage for mid-size MCUs. |
| Interface Support | Standard/Dual/Quad SPI with 104 MHz max CLK - delivers up to 416 MB/s effective throughput in Quad I/O mode. |
| Erase Granularity | Uniform 4 KB sectors (512 total); also supports 32 KB and 64 KB block erase - ideal for OTA update partitioning. |
| Write Cycle Endurance | 100,000 program/erase cycles per sector - suitable for frequent configuration or logging use cases. |
| Data Retention | 20 years at +85°C - validated for industrial temperature operation without refresh. |
| Supply Voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V logic domains and low-power MCU systems. |
| Active Current | 4 mA typical at 104 MHz - enables high-speed reads without thermal derating in compact enclosures. |
| Power-down Current | 1 µA typical - reduces system standby power in battery-backed or energy-harvesting designs. |
Pinout & Package
W25Q16DVUUJP is packaged in an 8-pad USON 4×3-mm (package code UU), with exposed pad for thermal dissipation and footprint optimized for automated assembly in high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives device into high-impedance state when deasserted; required to transition high→low before new instruction acceptance. |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes - carries read data or address bits depending on instruction phase. |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for status register writes; repurposed as IO2 in Quad mode when QE=1 - requires external pull-up if unused. |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; must be low-impedance and adjacent to exposed pad for stable noise margin. |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes - receives commands, addresses, and program data on rising CLK edge. |
| 6 CLK | Serial Clock Input | Synchronizes all SPI transfers; supports Mode 0 (CLK idle low) and Mode 3 (CLK idle high) - timing critical for setup/hold compliance. |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing read/write while /CS active; repurposed as IO3 in Quad mode - useful for multi-device bus arbitration. |
| 8 VCC | Power Supply | 2.7–3.6 V main supply; decoupling capacitor (100 nF) required within 5 mm of pin for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit enabling 4-line I/O for 4× throughput boost - must be set once during initialization to unlock full interface capability. |
| Continuous Read Mode | Configurable 8/16/32/64-byte wrap with ≤8-clock instruction overhead - enables true execute-in-place (XIP) from flash without RAM copy. |
| Security Registers | Three 256-byte OTP-lockable registers (LB1–LB3) for keys, calibration data, or secure boot assets - protected against overwrite after programming. |
| JEDEC SFDP Support | Read SFDP register (5Ah) returns discoverable parameters including density, erase types, and timing - simplifies auto-configuration in generic flash drivers. |
| Erase/Program Suspend | 75h/7Ah instructions allow pausing long erase/program operations to service higher-priority interrupts - critical for real-time deterministic response. |
| 64-bit Unique ID | Factory-programmed serial number accessible via 4Bh instruction - enables device-level traceability 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 |
|---|---|---|---|
| MX25L1606EM1I-12G | Same 16 M-bit density, 3.3 V supply, and SOIC-8/USON-8 packages; supports Dual/Quad SPI but max CLK = 80 MHz (vs. 104 MHz). | Limited to 40 MB/s Quad I/O throughput; lacks SFDP register and security register OTP locks. | Choose for cost-sensitive designs where 20% lower speed and no security registers are acceptable. |
| S25FL116K0XMFI041 | 16 M-bit, 3.0–3.6 V, 104 MHz Quad SPI; includes configurable reset pin and deeper power-down mode (100 nA), but only offers SOIC-8 and WSON-8 packages - no USON-4×3-mm. | No USON 4×3-mm option; reset pin adds flexibility but increases pin count; lacks 64-bit unique ID. | Prefer when ultra-low standby current or hardware reset control outweighs package size constraints. |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, W25Q16DVUUJP uniquely combines USON 4×3-mm footprint, 104 MHz Quad SPI, SFDP discoverability, and OTP-secured 256-byte registers - making it optimal for space-constrained, secure, high-throughput embedded boot applications.

FAQ
What is the package type of W25Q16DVUUJP?
W25Q16DVUUJP uses an 8-pad USON 4×3-mm package (package code UU), featuring a compact footprint, exposed thermal pad, and compatibility with standard reflow profiles. This package is distinct from SOIC, WSON, or TFBGA variants of the W25Q16DV family and is optimized for high-density PCB layouts.
Does W25Q16DVUUJP support Quad SPI mode out of the box?
No - W25Q16DVUUJP requires the Quad Enable (QE) bit in Status Register-2 to be set (via Write Status Register instruction 01h) to activate Quad SPI functionality. Until QE=1, /WP and /HOLD remain dedicated hardware control pins; after setting QE, they become IO2 and IO3 for 4-line data transfer.
How many erase cycles can W25Q16DVUUJP endure per sector?
W25Q16DVUUJP guarantees a minimum of 100,000 program/erase cycles per 4 KB sector. This endurance rating is specified under standard operating conditions (2.7–3.6 V, -40°C to +85°C) and applies uniformly across all 512 sectors, supporting robust logging and OTA update implementations.
Is there hardware write protection on W25Q16DVUUJP independent of software settings?
Yes - W25Q16DVUUJP provides dual-layer write protection: hardware-level via the active-low /WP pin (which locks status register writes), and software-level via status register bits (BP2–BP0, TB, SEC). Both can be used concurrently; /WP remains functional unless QE=1, in which case it becomes IO2.
What unique identification capability does W25Q16DVUUJP offer?
W25Q16DVUUJP includes a factory-programmed, unalterable 64-bit unique serial number accessible via the Read Unique ID Number instruction (4Bh). This identifier supports device-level traceability, secure boot binding, and counterfeit detection - and is independent of user-programmable memory contents.
