Product details
Overview
W25Q16JWSNIQ TR from Winbond is a 1.8V, 16M-bit (2MB) serial NOR flash memory with Dual/Quad SPI interface, supporting up to 133MHz Quad I/O clocking and 66MB/s continuous data transfer. It features uniform 4KB sectors (512 total), 32KB/64KB blocks, and operates across –40°C to +85°C for industrial applications including boot code storage and XIP execution.
For engineers reviewing the W25Q16JWSNIQ TR datasheet, W25Q16JWSNIQ TR pinout, W25Q16JWSNIQ TR application, or W25Q16JWSNIQ TR equivalent, key selection criteria include Quad SPI enable (QE bit), /WP and /HOLD pin functionality in Standard/Dual vs. Quad mode, 1.65–1.95V supply compliance, sector-level lock granularity, and WSON 6x5-mm package compatibility with PCB layout constraints.
Technical Context
The W25Q16JWSNIQ TR implements a flexible SPI command architecture supporting Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3) modes - with Quad operation requiring non-volatile QE bit set in Status Register-2. Its memory array comprises 8192 pages of 256 bytes each, enabling 1–256 byte page programming and erase operations at sector (4KB), 32KB block, 64KB block, or chip level.
Hardware write protection is implemented via active-low /WP pin controlling Status Register writes when combined with SRP/SRL bits; /HOLD pin enables transaction pausing during multi-device SPI sharing but is repurposed as IO3 in Quad mode. The device includes three 256-byte Security Registers, 64-bit unique ID, SFDP register, and supports Erase/Program Suspend & Resume for real-time system responsiveness.
Key Specifications

| 4 GND | Ground Reference | Signal and power ground reference; connects to PCB ground plane for noise immunity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input (DI); Dual/Quad SPI bidirectional I/O0 - used for instruction/address/data input |
| 6 CLK | Serial Clock Input | Edge-triggered timing source (Mode 0 or Mode 3 supported); max 133 MHz in Quad I/O mode |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transaction when low; becomes IO3 in Quad mode when QE=1; not available in Quad mode |
| 8 VCC | Power Supply | 1.65–1.95 V core supply; requires local 100nF decoupling near pin |
Key Features
| Feature | Design Value |

| Erase/Program Suspend & Resume | Allows interruption of long erase/program operations to service higher-priority tasks - critical for real-time OS environments |
| Individual Sector/Block Lock | 62 × 64KB blocks + 32 × 4KB top/bottom sectors each have dedicated lock bits - enables per-function firmware partitioning |
| Volatile & Non-Volatile Status Control | Status Register-1/2/3 support both volatile (power-on reset) and non-volatile (OTP-capable) configuration - ensures persistent security policy |
| 64-bit Unique ID & SFDP | Factory-programmed immutable ID enables device authentication; SFDP register provides standardized parameter discovery for host drivers |

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 |
|---|---|---|---|
| MX25L1633FZUI-10G | 1.8V, 16M-bit, supports DTR Quad SPI up to 80MHz; lacks individual sector lock bits and Security Registers | Suitable for cost-sensitive boot storage where advanced security and fine-grained locking are unnecessary | Prefer W25Q16JWSNIQ TR when sector-level locking, 64-bit UID, or Security Registers are required |
| S25FL132K0XMFI010 | 3V supply (2.7–3.6V), 16M-bit, supports Quad SPI up to 104MHz; includes 4KB sector protection but no OTP Security Registers | Used in legacy 3V industrial systems; incompatible with 1.8V logic without level-shifting | Select W25Q16JWSNIQ TR for new 1.8V designs requiring extended security, lower voltage, and broader temperature range |
Compared with MX25L1633FZUI-10G and S25FL132K0XMFI010, the W25Q16JWSNIQ TR uniquely combines 1.8V operation, individual sector locking, three OTP Security Registers, and 64-bit UID - making it the only option among the three qualified for secure, low-voltage, field-upgradable industrial firmware storage.

FAQ
What is the package type and footprint of W25Q16JWSNIQ TR?
W25Q16JWSNIQ TR uses an 8-pad WSON 6×5-mm package (JEDEC MO-241AC) with exposed thermal pad. It is pin-compatible with other Winbond WSON-packaged W25Qx devices and requires standard solder paste stencil design with 0.25 mm aperture for reliable reflow. The package code ZP is marked on the top-side marking.
Does W25Q16JWSNIQ TR support hardware reset via /RESET pin?
No, W25Q16JWSNIQ TR does not include a dedicated /RESET pin. The /HOLD pin (Pin 7) serves as IO3 in Quad mode but cannot function as hardware reset. Reset must be performed via software sequence: Enable Reset (66h) followed by Reset (99h), which returns the device to its power-on state within ~30 µs.
How is Quad SPI mode enabled on W25Q16JWSNIQ TR?
Quad SPI mode is enabled by setting the Quad Enable (QE) bit in Status Register-2 using Write Status Register-2 (31h) instruction. Once QE=1, pins /WP (Pin 3) and /HOLD (Pin 7) become IO2 and IO3 respectively. The device retains QE state across power cycles unless explicitly cleared.
What write protection mechanisms does W25Q16JWSNIQ TR provide?
W25Q16JWSNIQ TR offers layered write protection: hardware /WP pin control, volatile/non-volatile Status Register bits (BP2–BP0, TB, SEC, CMP), individual sector/block lock bits (39h/36h), and Security Register OTP locking. The WPS bit selects between status-register-based or individual-lock-based schemes.
Is W25Q16JWSNIQ TR compatible with standard SPI controllers?
Yes, W25Q16JWSNIQ TR is fully backward-compatible with standard SPI controllers using DI/DO/CLK//CS signals and Mode 0 or Mode 3. It executes all Standard SPI instructions (e.g., 03h Read Data, 02h Page Program) without requiring Quad-enable setup - default power-on state is Standard SPI mode.
