Product details
Overview
W25Q16JVUUJQ from Winbond is a 16 M-bit (2 MB) serial NOR flash memory supporting standard, dual, and quad SPI interfaces with up to 133 MHz clock frequency, 4 KB uniform sector architecture, and hardware/software write protection. It operates from 2.7V to 3.6V, delivers 66 MB/s continuous read throughput via Quad I/O, and targets embedded boot code storage and XIP execution in space-constrained microcontroller systems.
For engineers reviewing the W25Q16JVUUJQ datasheet, W25Q16JVUUJQ pinout, W25Q16JVUUJQ application, or W25Q16JVUUJQ equivalent, key selection considerations include quad SPI enable (QE bit), /HOLD vs /RESET pin behavior per package, 4 KB sector granularity for firmware partitioning, and non-volatile status register lock configuration (SRP/SRL, WPS).
Technical Context
The W25Q16JVUUJQ implements a SPI-compatible serial interface with Mode 0 and Mode 3 support, enabling compatibility with most MCU SPI peripherals. Its quad I/O mode requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set, repurposing /WP and /HOLD as IO2 and IO3 respectively.
It features three status registers (SR1–SR3) with volatile/non-volatile control bits for block/sector protection (BP2–BP0, TB, SEC, CMP), write protection lock-down (SRP, SRL), erase/program suspend/resume, and individual 64 KB block or 4 KB sector locks. The device supports JEDEC-standard manufacturer/device ID (9Fh), SFDP register (5Ah), and a unique 64-bit serial number (4Bh).

Pinout & Package
W25Q16JVUUJQ is supplied in an 8-pad USON 4×3-mm package (package code UU), with exposed pad thermal enhancement. Pin 1 is /CS; pins 2–3–5–7 are bidirectional I/Os (IO1, IO2, IO0, IO3); pin 4 is GND; pin 6 is CLK; pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware write protect when low; becomes IO2 in quad mode if QE=1 |
| 4 GND | Ground Reference | Primary return path; USON package includes exposed thermal pad connected to GND |
| 5 DI (IO0) | Serial Data Input / I/O0 | Unidirectional input in standard SPI; bidirectional I/O in dual/quad modes |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 and Mode 3 SPI operation |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing read/write; becomes IO3 in quad mode if QE=1; not available as /RESET in USON |
| 8 VCC | Power Supply | 2.7–3.6 V supply; internal voltage regulator enables stable core operation across range |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE) | Non-volatile bit in Status Register-2; enables 4-line I/O for 4× bandwidth increase without external bus widening |
| Individual Block Lock | 30 × 64 KB blocks + 32 × 4 KB top/bottom sectors each have dedicated lock bits; prevents accidental erase/program at sub-sector level |
| Security Registers | Three 256-byte OTP-capable security registers with independent lock bits (LB1–LB3); suitable for keys or calibration data |
| Continuous Read Wrap | Supports 8/16/32/64-byte wrap modes; eliminates address rollover overhead for streaming reads in XIP or DMA contexts |
| SFDP Compliance | JEDEC JESD216-compliant Serial Flash Discoverable Parameters register (5Ah); enables automatic driver configuration in modern bootloaders |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EZN-12G | Same density (16 M-bit), 104 MHz max clock, no Quad Enable bit; uses legacy SPANSION-compatible command set | Lacks SFDP register and 64-bit UID; requires fixed-mode initialization instead of auto-discovery | Choose for legacy designs already using MX25L series; avoid if Quad I/O bandwidth or bootloader auto-configuration is required. |
| S25FL116K0XMFI011 | 16 M-bit, 80 MHz max clock, supports octal DTR mode; includes hardware reset pin in all packages | Includes integrated ECC and error recovery; higher pin count (16-pin SOIC/WSON) required for reset functionality | Choose when system-level reliability mandates hardware reset assertion or built-in error correction; not drop-in due to pin count and timing differences. |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI011, W25Q16JVUUJQ offers superior quad SPI bandwidth (133 MHz vs ≤104 MHz), JEDEC SFDP support for driver portability, and smaller 8-pin USON packaging-making it optimal for new designs prioritizing footprint, throughput, and bootloader flexibility.

FAQ
What is the package type and pin count of W25Q16JVUUJQ?
W25Q16JVUUJQ is packaged in an 8-pad USON (Ultra Thin Small Outline No-lead) 4×3-mm body with exposed thermal pad (package code UU). It has eight terminals: /CS, DO(IO1), /WP(IO2), GND, DI(IO0), CLK, /HOLD(IO3), and VCC. This compact, leadless package supports reflow soldering and provides enhanced thermal performance over SOIC variants.
Does W25Q16JVUUJQ support hardware reset via a dedicated /RESET pin?
No, W25Q16JVUUJQ does not include a dedicated hardware /RESET pin. The /HOLD pin (Pin 7) functions as /HOLD in standard/dual SPI modes but becomes IO3 in quad SPI mode when the QE bit is set. Hardware reset is only available on SOIC-16 and TFBGA packages of the W25Q16JV family-not on the USON UU variant. System-level reset must be handled via software reset sequence (66h + 99h) or power cycling.
How is quad SPI mode enabled on W25Q16JVUUJQ?
Quad SPI mode on W25Q16JVUUJQ is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) using the Write Status Register-2 instruction (31h). Once QE = 1, the /WP and /HOLD pins become IO2 and IO3, enabling four-line bidirectional data transfer. The change is non-volatile, persisting across power cycles unless explicitly cleared.
What write protection mechanisms does W25Q16JVUUJQ support?
W25Q16JVUUJQ supports multiple write protection layers: hardware protection via the active-low /WP pin; software protection using Status Register bits (SRP, SRL, BP2–BP0, TB, SEC, CMP); and individual sector/block locks controlled by 39h/36h instructions. The WPS bit in Status Register-3 selects between status-register-based or individual-lock-based schemes, offering flexible, hierarchical data integrity control.
Is W25Q16JVUUJQ compatible with JEDEC-standard SFDP and unique ID features?
Yes, W25Q16JVUUJQ fully supports JEDEC JESD216-compliant Serial Flash Discoverable Parameters (SFDP) via instruction 5Ah, enabling automatic driver configuration in UEFI, Linux MTD, and RTOS bootloaders. It also provides a factory-programmed, globally unique 64-bit serial number accessible via instruction 4Bh-critical for device authentication and firmware binding in secure boot implementations.
