Product details
Overview
W25Q16JLUXIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory supporting Standard, Dual, and Quad SPI interfaces with up to 104 MHz clock rate, 4 KB uniform sector erase granularity, and 2.3–3.6 V single-supply operation. It delivers 50 MB/s continuous read throughput in Quad I/O mode and is used for code execution (XIP), firmware storage, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q16JLUXIG TR datasheet, W25Q16JLUXIG TR pinout, W25Q16JLUXIG TR application, or W25Q16JLUXIG TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD or /RESET pin functional mapping, 4 KB sector protection granularity, and USON 2×3 mm package compatibility with high-density PCB layouts.
Technical Context
The W25Q16JLUXIG TR implements a flexible SPI-compatible interface 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 memory array comprises 8,192 × 256-byte pages organized into 512 erasable 4 KB sectors and 32 erasable 64 KB blocks.
It supports hardware write protection via active-low /WP and /HOLD pins (functional only when QE = 0), volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP), and 3 × 256-byte OTP-locked security registers. The device features JEDEC-standard manufacturer/device ID, 64-bit unique serial number, and SFDP register for discoverable parameters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes), enabling compact firmware storage without external memory expansion. |
| Interface Support | Standard/Dual/Quad SPI with 104 MHz max CLK; enables 208 MHz (Dual) or 416 MHz (Quad) effective throughput for XIP or fast boot loading. |
| Erase Granularity | Uniform 4 KB sectors (512 total); allows fine-grained firmware update partitioning and data logging without disturbing adjacent code. |
| Write Cycle Endurance | Minimum 100,000 program/erase cycles per sector; ensures long-term reliability in field-upgradable embedded devices. |
| Data Retention | Greater than 20 years at +25°C; guarantees persistent storage of calibration data, device IDs, and configuration across product lifetime. |
| Supply Voltage | 2.3 V to 3.6 V single supply; compatible with 3.3 V logic domains and low-power MCU host systems. |
| Power Consumption | 2 mA typical active current; <1 µA power-down current; reduces system-level standby power in battery-operated applications. |
Pinout & Package
W25Q16JLUXIG TR is supplied in an 8-pad USON 2×3 mm package (package code UX), with exposed pad for thermal dissipation and space-constrained layout suitability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; places DO/IO pins in high-impedance state when deasserted to allow SPI bus sharing. |
| DO (IO1) | Serial Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes bidirectional IO1 in Dual/Quad modes for simultaneous read/write. |
| /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write lock for status register when QE = 0; repurposed as IO2 in Quad mode (QE = 1). |
| GND | Ground Reference | Primary return path for all internal circuitry and I/O signaling; must be low-impedance for noise immunity. |
| DI (IO0) | Serial Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes bidirectional IO0 in Dual/Quad modes for full-duplex operation. |
| CLK | Serial Clock Input | Synchronizes all SPI transactions; supports Mode 0 and Mode 3; timing-critical for setup/hold compliance. |
| /HOLD or /RESET (IO3) | Hold/Reset Input / Bidirectional I/O | Pauses ongoing SPI operation when QE = 0; becomes IO3 in Quad mode; configurable as hardware reset on supported packages. |
| VCC | Power Supply | 2.3–3.6 V primary supply; powers core logic, charge pumps, and I/O buffers; requires local decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Enable (QE) bit | Non-volatile Status Register-2 bit that unlocks IO2/IO3 functionality and enables Quad SPI instructions-required for 416 MHz equivalent throughput. |
| Erase/Program Suspend & Resume | Allows interruption of long-duration erase/program operations to service time-critical host tasks, then resume without data loss or re-initialization. |
| 64-bit Unique Serial Number | Factory-programmed per-device identifier enabling secure firmware binding, anti-cloning, and device-specific configuration provisioning. |
| 3 × 256-byte Security Registers | OTP-lockable memory regions for storing cryptographic keys, calibration offsets, or license tokens-protected against accidental overwrite or readout. |
| Discoverable Parameters (SFDP) | Standardized register (0x5A) providing host software with runtime-accessible geometry, timing, and feature flags-eliminates hard-coded assumptions. |

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 2×3 mm option; lacks SFDP register and OTP security registers. | Supports basic XIP and firmware storage but not advanced secure boot or runtime parameter discovery. | Select when footprint compatibility with legacy SOIC-8 designs is required and security features are unnecessary. |
| S25FL116K0XMFI041 | 16 M-bit with 3.0 V supply range only; includes HyperBus interface option; supports deeper power-down mode (<100 nA). | Better suited for ultra-low-power always-on monitoring; HyperBus enables higher bandwidth than Quad SPI in pin-limited designs. | Choose when system requires sub-µA sleep current or migration path to HyperFlash-compatible controllers. |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI041, W25Q16JLUXIG TR uniquely combines USON 2×3 mm packaging, SFDP support, OTP security registers, and full Quad SPI performance in a single 2.3–3.6 V supply device-making it optimal for space-constrained, secure, and field-upgradable embedded systems.

FAQ
What is the package type and dimensions of the W25Q16JLUXIG TR?
The W25Q16JLUXIG TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm with an exposed thermal pad. This compact footprint supports high-density PCB layouts in space-constrained applications such as wearable medical devices and miniaturized IoT sensors. The package code is UX, and it complies with JEDEC MO-252 standards.
Does the W25Q16JLUXIG TR support Quad SPI mode out of the box?
No-the W25Q16JLUXIG TR requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to '1' to activate Quad SPI functionality. By default, QE = 0, so /WP and /HOLD operate as hardware protection pins. Setting QE enables IO2 and IO3, allowing Fast Read Quad I/O (0xEBh) and other Quad instructions. This configuration is persistent across power cycles.
How does the /HOLD pin function differ between Standard/Dual and Quad SPI modes on the W25Q16JLUXIG TR?
In Standard and Dual SPI modes (QE = 0), the /HOLD pin pauses ongoing operations while /CS is low, placing DO in high-impedance and ignoring DI/CLK-ideal for multi-device SPI bus arbitration. In Quad SPI mode (QE = 1), the /HOLD pin is reassigned as IO3 and loses its hold function; the pin becomes a bidirectional data line essential for Quad I/O communication.
What is the purpose of the 64-bit Unique ID in the W25Q16JLUXIG TR?
The factory-programmed 64-bit Unique ID in the W25Q16JLUXIG TR provides a tamper-resistant, unclonable device fingerprint used for secure boot attestation, per-unit firmware licensing, and cryptographic key binding. It is readable via instruction 0x4Bh and remains constant across erase/program cycles-enabling robust device identity management in certified embedded systems.
Can the W25Q16JLUXIG TR be used in automotive applications?
The W25Q16JLUXIG TR is rated for –40°C to +85°C operation and belongs to Winbond's automotive-qualified W25Q family (AEC-Q100 Grade 3). While the specific W25Q16JLUXIG TR variant is not individually AEC-Q100 certified, its underlying design, process, and test flow align with automotive requirements. For ASIL-B systems, validation per application context and board-level qualification is recommended.
