Product details
Overview
W25Q16DVUUIG 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 single 2.7–3.6 V supply. It delivers up to 416 MHz equivalent data throughput in Quad I/O mode and supports execute-in-place (XIP) for code storage and boot applications in space-constrained embedded systems.
For engineers reviewing the W25Q16DVUUIG TR datasheet, W25Q16DVUUIG TR pinout, W25Q16DVUUIG TR application, or W25Q16DVUUIG TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector erase granularity, hardware write protection via /WP and /HOLD pins, and USON 4×3-mm (UU) package compatibility with high-density PCB layouts.
Technical Context
The W25Q16DVUUIG 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 = 1 in Status Register-2. Its internal architecture includes a 256-byte page buffer, 512 × 4 KB erasable sectors, and 32 × 64 KB erasable blocks, enabling flexible firmware partitioning.
It integrates volatile and non-volatile status registers with BP0–BP2, TB, SEC, CMP, SRP0/SRP1, and SUS bits for granular software/hardware write protection, plus 64-bit unique ID, SFDP register, and three 256-byte OTP-locked security registers for secure boot and parameter storage.

Pinout & Package
W25Q16DVUUIG TR is packaged in an 8-pad USON 4×3-mm (package code UU), with exposed pad thermal enhancement. Pin functions are shared across SPI modes: /CS enables device selection; CLK synchronizes transfers; DI/DO become bidirectional IO0/IO1 in Dual/Quad modes; /WP and /HOLD serve as IO2/IO3 when QE=1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO/IOx high-Z when high; required low-to-high transition after power-up to accept commands |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad modes; used for Fast Read instructions |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; becomes IO2 in Quad mode (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; connects to exposed pad for thermal dissipation |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional in Dual/Quad modes; carries instructions and addresses |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference (Mode 0 or Mode 3 supported); max 104 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses active transfers when low (CS must be low); becomes IO3 in Quad mode (QE=1) |
| 8 VCC | Power Supply | 2.7–3.6 V single supply; decoupling capacitor required near pin for stable operation |

FAQ
What is the package type and footprint of W25Q16DVUUIG TR?
W25Q16DVUUIG TR uses an 8-pad USON 4×3-mm package (package code UU) with exposed thermal pad. It is pin-compatible with other W25Q16DV variants in USON 4×3-mm, and shares identical pinout and electrical characteristics with the ZP (WSON 6×5-mm) and SN (SOIC 150-mil) versions, differing only in physical dimensions and thermal performance.
Does W25Q16DVUUIG TR support Quad SPI mode out of the box?
No - W25Q16DVUUIG TR requires the Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., EBh, 6Bh) function. This is a non-volatile setting; once programmed, QE remains active until cleared. The /WP and /HOLD pins become IO2 and IO3 respectively only after QE=1.
How does hardware write protection work on W25Q16DVUUIG TR?
W25Q16DVUUIG TR provides dual-layer hardware write protection: the /WP pin (active-low) locks the status register when asserted, and the TB, BP2–BP0, and SRP0/SRP1 bits configure sector/block-level protection. When /WP is held low and SRP1=1, status register writes are blocked regardless of software commands - critical for preventing accidental firmware corruption.
What is the purpose of the /HOLD pin on W25Q16DVUUIG TR?
The /HOLD pin on W25Q16DVUUIG TR pauses ongoing SPI transfers while /CS remains low, placing DO/IOx in high-impedance state and ignoring CLK/DI activity. This enables multi-device SPI bus sharing without arbitration logic. In Quad SPI mode (QE=1), /HOLD becomes IO3 and loses hold functionality - use software suspend (75h/7Ah) instead.
Can W25Q16DVUUIG TR be used for execute-in-place (XIP) applications?
Yes - W25Q16DVUUIG TR supports true XIP via Fast Read Quad I/O (EBh) and Continuous Read Mode, achieving up to 52 MB/s sustained throughput. Its 8-clock instruction overhead and wrap-mode addressing allow deterministic instruction fetch timing, making it suitable for running ARM Cortex-M or RISC-V code directly from flash without loading into RAM.
