Product details
Overview
W25Q16JLSNIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 104 MHz clock rate, 4 KB uniform sector erase granularity, and 100K program/erase cycles per sector - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q16JLSNIG TR datasheet, W25Q16JLSNIG TR pinout, W25Q16JLSNIG TR application, or W25Q16JLSNIG TR equivalent, key selection criteria include quad I/O enable (QE bit), /HOLD vs /RESET pin configuration (HOLD/RST bit), 2.3–3.6 V supply compatibility, 4 KB sector flexibility for parameter storage, and JEDEC-compliant SFDP register support for automatic configuration discovery.
Technical Context
The W25Q16JLSNIG TR implements a SPI-compatible command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where Quad mode requires non-volatile QE=1 in Status Register-2 and repurposes /WP and /HOLD as IO2 and IO3. It supports XIP via Fast Read Quad I/O (EBh) at up to 416 MHz equivalent throughput.
Its architecture includes 512 × 4 KB erasable sectors and 32 × 64 KB blocks, with programmable write protection via status register bits (BP2–BP0, TB, SEC, CMP), volatile/non-volatile SRP/SRL lock, and 3×256-byte OTP-locked security registers. The device uses Mode 0 or Mode 3 SPI timing and features hardware /WP and /HOLD pins active-low - both disabled when QE=1.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable: high = high-Z outputs and standby current; must transition high→low before instruction acceptance |
| DO (IO1) | Data Output / Bidirectional I/O | Standard SPI output only; becomes IO1 in Dual/Quad mode - used for read data and status on falling CLK edge |
| /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write lock for status register when QE=0; becomes IO2 in Quad mode (QE=1) |
| GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB connection |
| DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input only; becomes IO0 in Dual/Quad mode - carries instructions, addresses, and write data on rising CLK edge |
| CLK | Serial Clock Input | Edge-triggered timing reference for all SPI operations; supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| /HOLD or /RESET (IO3) | Hold/Reset Input / Bidirectional I/O | Pauses ongoing SPI transfer when low (QE=0); becomes IO3 in Quad mode (QE=1); configurable via HOLD/RST bit in SR3 |
| VCC | Power Supply | Single 2.3–3.6 V supply; internal voltage regulator ensures stable core operation across range |
Key Features
| Feature | Design Value |
|---|---|
| Quad Enable (QE) bit | Non-volatile Status Register-2 bit enabling IO2/IO3 functionality and Fast Read Quad I/O (EBh) for 4× throughput vs standard SPI |

|---|---|
|
Use Scenario: Storing boot loader, real-time OS kernel, and field-upgradable control logic in programmable logic controllers with no external RAM shadowing. IC Role / Device Role / Timing Role: Primary non-volatile code storage with XIP capability via Fast Read Quad I/O (EBh) to reduce BOM cost and board space. Use Value: 4 KB sector erase enables atomic firmware updates without disrupting running control tasks; 100K endurance supports decades of field reprogramming. |
Use Scenario: Hosting dual firmware images (active + candidate) and configuration parameters in battery-powered sensor gateways requiring over-the-air updates. IC Role / Device Role / Timing Role: Dual-image partition manager with hardware write protection (/WP pin + BP bits) preventing corruption during power-loss mid-update. Use Value: <1 µA power-down current extends battery life; SFDP register allows runtime driver adaptation to varying clock speeds across device generations. |
| Automotive Infotainment Boot ROM | Medical Diagnostic Instrument Code Storage |

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), 3.3 V only (2.7–3.6 V), no Quad I/O support - limited to Dual SPI max 80 MHz | Lacks QE bit, SFDP, and security registers - unsuitable for XIP or secure boot use cases | Select only if Quad SPI and security features are unnecessary and legacy SPI interface suffices |
| S25FL116K0XMFI041 | 16 M-bit, 2.7–3.6 V, Quad SPI capable, but uses different command set (Spansion/Infineon) and lacks OTP security registers | Requires driver porting due to non-Winbond instruction mapping; no 64-bit UID or SFDP v1.6 support | Choose only when migrating from existing Spansion-based designs and security requirements are minimal |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI041, the W25Q16JLSNIG TR delivers higher throughput (104 MHz Quad SPI), built-in security primitives (OTP registers, UID), and standardized configuration (SFDP), making it optimal for new designs requiring XIP, secure boot, or field-upgrade resilience.

FAQ
What is the package type and lead count of the W25Q16JLSNIG TR?
The W25Q16JLSNIG TR uses an 8-pin SOIC 150-mil (5.3 mm × 4.1 mm) package with gull-wing leads and 1.27 mm pitch. Its package code is SN, and it is RoHS-compliant and halogen-free. This variant does not include a dedicated /RESET pin - the /HOLD pin serves dual function and can be configured as /RESET via HOLD/RST bit in Status Register-3 when QE=0.
Does the W25Q16JLSNIG TR support Quad SPI mode, and how is it enabled?
Yes, the W25Q16JLSNIG TR supports Quad SPI mode using instructions like Fast Read Quad I/O (EBh). It is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 (bit 1 of SR2) via Write Status Register (31h) instruction. When QE=1, /WP and /HOLD pins become IO2 and IO3, respectively, completing the 4-line I/O bus required for Quad operation.
How many program/erase cycles does the W25Q16JLSNIG TR guarantee per sector?
The W25Q16JLSNIG TR guarantees a minimum of 100,000 program/erase cycles per 4 KB sector. This endurance rating applies across the full operating temperature range (−40°C to +85°C) and is validated per JEDEC standards. Sector-level wear leveling must be implemented in firmware to achieve this lifetime in field use.
What is the purpose of the 64-bit Unique ID in the W25Q16JLSNIG TR?
Each W25Q16JLSNIG TR unit has a factory-programmed, read-only 64-bit Unique ID accessible via the Read Unique ID Number (4Bh) instruction. It provides cryptographic binding for secure boot, device authentication, and firmware licensing - ensuring that software images are tied to specific hardware units and preventing cloning or unauthorized redistribution.
Can the W25Q16JLSNIG TR be used in power-sensitive battery-operated devices?
Yes, the W25Q16JLSNIG TR is well-suited for battery-operated devices: it draws only 2 mA typical during active read/write operations and less than 1 µA in power-down mode (B9h instruction). Its 2.3–3.6 V supply range aligns with single-cell Li-ion/LiPo and 2xAA alkaline configurations, and its fast Quad SPI access reduces active time, further lowering average power consumption.
