Product details
Overview
W25Q16DVUUJP TR from Winbond is a 16M-bit (2MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104MHz clock capability, 4KB uniform sector architecture, and XIP-capable continuous read mode - deployed for code storage and execution in microcontroller boot loaders, IoT firmware images, and embedded BIOS/UEFI modules.
For engineers reviewing the W25Q16DVUUJP TR datasheet, W25Q16DVUUJP TR pinout, W25Q16DVUUJP TR application, or W25Q16DVUUJP TR equivalent, this page delivers verified pin functions, real-world timing performance (416MHz Quad I/O equivalent), JEDEC-compliant identification, 64-bit unique ID, and hardware write protection logic - all confirmed for the UU (4×3-mm USON) package variant.
Technical Context
The W25Q16DVUUJP TR 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 enablement in Status Register-2. Its block diagram integrates a 256-byte page buffer, sector/block erase control logic, and SFDP register for discoverable parameters.
It supports full instruction-level compatibility with JEDEC JESD216B, including Fast Read Quad I/O (EBh), Word Read Quad I/O (E7h), and Octal Word Read Quad I/O (E3h), enabling true execute-in-place (XIP) with ≤8-clock address overhead. Erase suspend/resume, security registers (3×256-byte OTP-locked), and top/bottom 4KB array protection are implemented in silicon.
Key Specifications

Pinout & Package
W25Q16DVUUJP TR uses an 8-pad USON 4×3-mm package (package code UU), with exposed pad thermal connection. Pin 1 (/CS) is located at top-left corner; pin numbering proceeds counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z outputs, standby current); low = device selected and responsive to commands |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Standard SPI output (DO); Dual/Quad SPI bidirectional data line IO1 - used for read data and command/address input in multi-I/O modes |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write protect when QE=0; becomes IO2 in Quad mode - enables 4-line data transfer but disables hardware WP function |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable SPI timing and noise immunity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input (DI); Dual/Quad SPI bidirectional data line IO0 - carries instructions, addresses, and program data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference: rising edge for input sampling, falling edge for output valid - supports SPI Mode 0 and Mode 3 |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transaction when active low; becomes IO3 in Quad mode - allows bus sharing without CS toggling |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor required within 5 mm of pin for transient current stability during erase/program |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | Enables true XIP with ≤8-clock instruction overhead per 24-bit address - eliminates external RAM buffering for boot code execution |
| Quad Enable (QE) Bit | Non-volatile status register bit (SR2[1]) that reassigns /WP and /HOLD to IO2/IO3 - required before any Quad SPI instruction executes |
| 64-Bit Unique Serial Number | Factory-programmed, read-only identifier per die - supports secure firmware binding, anti-cloning, and field device authentication |
| Security Registers | Three 256-byte OTP-lockable registers - used for cryptographic keys, calibration data, or license tokens with hardware-enforced write protection |
| SFDP Register Compliance | JESD216B-compliant Serial Flash Discoverable Parameters - enables automatic driver configuration without hard-coded timing or geometry tables |
| Erase/Program Suspend | Allows background erase or program to pause on command (75h), then resume (7Ah) - critical for real-time systems requiring deterministic latency |

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 | 16Mb density, 8-pin SOIC 150-mil, max 86MHz clock, no Quad I/O support - only Standard/Dual SPI | Lacks Quad SPI and XIP-optimized continuous read mode - unsuitable for high-speed boot or real-time firmware streaming | Select when cost sensitivity outweighs bandwidth needs and board layout accommodates larger SOIC footprint |
| S25FL116K0XMFI041 | 16Mb density, 8-pin USON 4×3-mm, 104MHz clock, Quad SPI, but uses different status register map and lacks SFDP v1.6B compliance | Requires custom driver adaptation for status bits and erase commands - increases validation effort for Linux or RTOS integration | Select only if existing Cypress/Fujitsu ecosystem alignment justifies non-JEDEC-standard register behavior |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, the W25Q16DVUUJP TR delivers superior XIP performance via 416MHz Quad I/O, JEDEC-standard SFDP auto-configuration, and factory-programmed unique ID - reducing firmware integration risk and enabling faster boot-critical paths.

FAQ
What is the package type and footprint of W25Q16DVUUJP TR?
W25Q16DVUUJP TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 4 mm × 3 mm with 0.5 mm pitch. It features an exposed thermal pad on the bottom and is RoHS-compliant. This compact footprint is optimized for space-constrained PCB layouts in portable and IoT devices, and differs from SOIC or TFBGA variants of the same W25Q16DV family.
Does W25Q16DVUUJP TR support Quad SPI operation out of the box?
No - W25Q16DVUUJP TR requires the Quad Enable (QE) bit in Status Register-2 to be set (to '1') before Quad SPI instructions like Fast Read Quad I/O (EBh) can function. By default, QE=0 after power-up or reset, so /WP and /HOLD retain their hardware protection roles. Setting QE permanently reassigns those pins to IO2 and IO3, disabling hardware write protection unless software-based BP bits are used.
How does the Continuous Read Mode in W25Q16DVUUJP TR improve system performance?
W25Q16DVUUJP TR's Continuous Read Mode reduces instruction overhead to as few as 8 clock cycles for addressing, enabling efficient sequential reads without repeated command issuance. This allows true execute-in-place (XIP) operation directly from flash, eliminating RAM copy latency and reducing boot time by up to 40% compared to standard SPI flash - especially beneficial in Cortex-M and RISC-V boot sequences.
Can W25Q16DVUUJP TR be used for secure firmware storage?
Yes - W25Q16DVUUJP TR includes three 256-byte security registers with one-time-programmable (OTP) lock bits, a 64-bit unique serial number per die, and hardware/software write protection (via /WP pin and BP/SRP bits). These features enable cryptographic key storage, device identity binding, and tamper-resistant firmware signing - validated in automotive and industrial security frameworks.
What is the endurance and data retention specification for W25Q16DVUUJP TR?
W25Q16DVUUJP TR guarantees ≥100,000 program/erase cycles per 4KB sector and 20 years of data retention at +85°C ambient temperature. These specifications are tested and documented per JEDEC standards, making it suitable for applications requiring frequent firmware updates (e.g., OTA-enabled edge devices) and long-life deployments in harsh thermal environments.
