Product details
Overview
W25Q16DVUZIG TR 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 1 µA power-down current. It serves as non-volatile program/data storage in microcontroller boot code, firmware update, and XIP-capable embedded systems.
For engineers reviewing the W25Q16DVUZIG TR datasheet, W25Q16DVUZIG TR pinout, W25Q16DVUZIG TR application, or W25Q16DVUZIG TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector granularity for parameter storage, hardware write protection via /WP and /HOLD pins, and USON 4×4-mm (UZ) package compatibility with high-density PCB layouts.
Technical Context
The W25Q16DVUZIG 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 setting the non-volatile QE bit in Status Register-2. Its internal architecture includes an 8,192-page array (256 bytes/page), 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks.
It supports JEDEC-standard identification (9Fh), 64-bit unique serial number (4Bh), SFDP register (5Ah), and security registers with OTP locks. Erase/program suspend/resume functionality enables concurrent background operations without halting host communication.
Key Specifications

| Erase Granularity | Uniform 4 KB sectors (512 total), plus 32 KB and 64 KB block erase options |
| Write Protection | Hardware /WP pin + software BP0–BP2, TB, SEC, CMP bits for flexible sector locking |
| Power Supply | Single 2.7 V to 3.6 V supply; 4 mA active current, 1 µA typical power-down current |
| Operating Temp | –40 °C to +85 °C - qualified for industrial-grade embedded applications |

Pinout & Package
W25Q16DVUZIG TR uses the 8-pad USON 4×4-mm package (package code UZ), with wettable flank side walls for automated optical inspection. Pin 1 is marked by a dot; pin numbering follows counter-clockwise orientation from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO/IOx to high-Z when high; required low-to-high transition after power-up before instruction acceptance |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Standard SPI output (DO); becomes IO1 in Dual/Quad mode - used for read data and status in all SPI configurations |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for Status Register when QE = 0; repurposed as IO2 in Quad mode (QE = 1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance connection to minimize noise coupling |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input (DI); becomes IO0 in Dual/Quad mode - carries instructions, addresses, and write data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference (Mode 0 or Mode 3 supported); must meet tCH/tCL min/max specs for reliable command latching |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transfer while /CS remains low; repurposed as IO3 in Quad mode (QE = 1) |
| 8 VCC | Power Supply | 2.7–3.6 V nominal; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit enabling IO2 (/WP) and IO3 (/HOLD) for 4-line data transfers - required for 416 MB/s throughput |
| Continuous Read Mode | Configurable wrap length (8/16/32/64 bytes) with only 8-clock instruction overhead - enables true execute-in-place (XIP) from flash |
| Security Registers | Three 256-byte OTP-locked security registers - suitable for storing cryptographic keys or calibration data inaccessible to standard read commands |
| Erase/Program Suspend | 75h/7Ah commands allow pausing long erase/program operations to service urgent host reads - critical for real-time system responsiveness |
| Unique 64-bit ID | Factory-programmed serial number readable via 4Bh instruction - enables device-level traceability and secure firmware binding |
| SFDP Support | Standard Flash Discovery Parameter (5Ah) register provides programmable, vendor-agnostic configuration metadata for automatic driver initialization |

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 |
|---|---|---|---|
| MX25L1606EZN-12G | Same density (16 M-bit), SOIC-8 package only; no USON 4×4-mm option; lacks SFDP and security registers | Lower-cost replacement where Quad SPI and security features are unused | Select if board layout uses SOIC-8 and advanced features like SFDP or OTP security are unnecessary |
| AT25SF161-UUN | 16 M-bit with 133 MHz Quad SPI clock; includes Deep Power-Down mode (1 µA); supports 1.8 V/3.3 V dual supply | Better suited for ultra-low-power battery applications requiring voltage flexibility | Choose when system operates below 2.7 V or demands deeper sleep states than W25Q16DVUZIG TR's 1 µA power-down |
Compared with MX25L1606EZN-12G and AT25SF161-UUN, the W25Q16DVUZIG TR uniquely combines USON 4×4-mm packaging, integrated SFDP support for plug-and-play driver initialization, and three OTP-locked security registers - making it optimal for space-constrained, secure, and auto-configuring embedded designs.

FAQ
What is the package type and footprint of W25Q16DVUZIG TR?
The W25Q16DVUZIG TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 4 mm × 4 mm with 0.5 mm pitch and wettable flank side walls. Its footprint matches JEDEC MO-255 standards and is optimized for automated optical inspection and high-density PCB assembly. This exact UZ package variant is confirmed in Winbond's official ordering information table.
Does W25Q16DVUZIG TR support execute-in-place (XIP) operation?
Yes, the W25Q16DVUZIG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to just 8 clocks for address setup and enables seamless sequential access. When paired with a host controller supporting Quad SPI and configured with QE=1, the W25Q16DVUZIG TR delivers up to 416 MB/s effective bandwidth - sufficient for direct code execution in microcontrollers like ARM Cortex-M7 or RISC-V cores.
How is hardware write protection implemented on W25Q16DVUZIG TR?
Hardware write protection on the W25Q16DVUZIG TR is implemented using the /WP pin (Pin 3), which - when held low - prevents writes to the Status Register regardless of software commands. This works in conjunction with software-configurable Block Protect (BP0–BP2), Top/Bottom (TB), and Sector Protect (SEC) bits to lock individual 4 KB sectors. The /WP pin remains functional only when the Quad Enable (QE) bit is cleared (QE=0).
Can W25Q16DVUZIG TR be used in automotive applications?
The W25Q16DVUZIG TR is rated for –40°C to +85°C operation and meets industrial reliability standards (100,000 P/E cycles, 20-year data retention), but it is not AEC-Q100 qualified. For automotive applications requiring formal qualification (e.g., ADAS ECUs), Winbond offers the pin-compatible W25Q16JW series. The W25Q16DVUZIG TR may be used in non-safety-critical automotive subsystems (infotainment, body control) where qualification is not mandated.
What is the function of the /HOLD pin on W25Q16DVUZIG TR?
The /HOLD pin (Pin 7) on the W25Q16DVUZIG TR pauses ongoing SPI transactions while /CS remains asserted low. When pulled low, it places DO/IOx in high-impedance state and ignores CLK/DI activity - allowing other SPI peripherals to share the bus without interrupting the W25Q16DVUZIG TR's internal operation. In Quad SPI mode (QE=1), this pin functions as IO3 instead of /HOLD.
