Product details
Overview
W25Q16JVSNIM from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes, organized as 8,192 × 256-byte pages with uniform 4 KB sector erase granularity, operating from 2.7V to 3.6V, and rated for -40°C to +85°C - used for code execution-in-place (XIP), firmware storage, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q16JVSNIM datasheet, W25Q16JVSNIM pinout, W25Q16JVSNIM application, or W25Q16JVSNIM equivalent, key selection considerations include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin SOIC packages, DTR timing compliance, 133 MHz max SPI clock support, and JEDEC SFDP register compatibility for auto-configuration.
Technical Context
The W25Q16JVSNIM implements a quad I/O-capable SPI interface with non-volatile Quad Enable (QE) bit in Status Register-2; when QE=1, IO2 and IO3 are enabled via /WP and /HOLD pins respectively, disabling their hardware protection functions. It supports three distinct operational modes: Standard/Dual SPI (Mode 0/3), Quad SPI, and QPI - with mode transitions controlled by Enter QPI (38h) and Exit QPI (FFh) instructions.
Its architecture includes volatile/non-volatile status register bits for block protection (BP2–BP0, TB, SEC, CMP), erase/program suspend/resume capability, 64-bit unique ID, three 256-byte one-time-programmable (OTP) security registers, and SFDP v1.6 compliance for standardized parameter discovery - enabling plug-and-play integration with modern boot ROMs and flash-aware toolchains.

Pinout & Package
W25Q16JVSNIM is supplied in an 8-pin SOIC 150-mil package (Package Code SN), with pin 1 marked by a notch or dot. All pins are electrically identical across SOIC, WSON, and USON variants per datasheet Section 3.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; must transition high→low after power-up before first instruction |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad SPI/QPI; requires QE=1 for Quad I/O use |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write-protection for status register when QE=0; becomes IO2 in Quad mode (QE=1); not available in QPI if /WP pin is repurposed |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB connection to minimize noise coupling |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad SPI/QPI; essential for instruction/address loading |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI operations; supports Mode 0 and Mode 3; max 133 MHz frequency |
| 7 /HOLD or /RESET (IO3) | Hold/Reset Input / Bidirectional I/O | Active-low pause signal in Standard/Dual SPI; dedicated /RESET only in TFBGA; becomes IO3 in Quad mode (QE=1); function depends on SR2.HOLD/RST bit |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required within 10 mm of pin per layout guidelines |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| MX25L1606EM1I-12G | 16 M-bit, 3V, SOIC-8; supports standard/Dual/Quad SPI but no QPI or DTR; max clock 80 MHz | Lacks QPI instruction reduction and DTR throughput boost; lower performance for XIP-critical designs | Choose when QPI/DTR features are unnecessary and cost sensitivity outweighs speed requirements |
| S25FL116K0XMFI041 | 16 M-bit, 3V, SOIC-8; supports Quad SPI and HyperBus interface; includes built-in ECC and sector protection lockbits | Offers stronger data integrity via on-die ECC but lacks DTR and has different command set; not drop-in compatible | Prefer for safety-critical applications requiring error correction, but expect driver porting effort due to non-SpiFlash command mapping |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, W25Q16JVSNIM delivers superior throughput via DTR and QPI modes, broader legacy SPI compatibility, and Winbond's mature SpiFlash ecosystem - making it optimal for cost-sensitive, high-speed XIP and firmware update use cases where ECC is not mandated.

FAQ
What is the package type and marking for W25Q16JVSNIM?
W25Q16JVSNIM uses an 8-pin SOIC 150-mil package (Package Code SN) with top-side marking "W25Q16JV" followed by date code and traceability symbols. The "SN" suffix confirms the SOIC-150 variant, distinct from SS (SOIC-208), ZP (WSON), or UX (USON) versions - all sharing identical electrical specs but differing in footprint and thermal profile.
Does W25Q16JVSNIM support hardware reset via /RESET pin?
No - W25Q16JVSNIM in SOIC-8 package does not have a dedicated /RESET pin. Pin 7 functions as /HOLD or /RESET depending on the HOLD/RST bit in Status Register-2, but only when QE=0. When QE=1 (Quad mode enabled), pin 7 becomes IO3 and hardware reset is unavailable. True hardware reset requires the TFBGA package (TB) variant.
How is Quad SPI mode enabled on W25Q16JVSNIM?
Quad SPI mode on W25Q16JVSNIM is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register-2 (31h) instruction. Once QE=1, pins /WP (pin 3) and /HOLD (pin 7) become IO2 and IO3, enabling four-line data transfer. The change persists across power cycles unless explicitly cleared.
What is the purpose of the DTR (Double Transfer Rate) feature in W25Q16JVSNIM?
The DTR feature in W25Q16JVSNIM allows address and data to be latched on both rising and falling edges of the serial clock - doubling effective throughput without raising the clock frequency. This is implemented in instructions like DTR Fast Read (0Dh) and DTR Burst Read (0Eh), improving bandwidth efficiency in bandwidth-constrained systems while maintaining signal integrity.
Can W25Q16JVSNIM be used for secure firmware updates?
Yes - W25Q16JVSNIM supports secure firmware updates via multiple mechanisms: sector-level hardware write protection using /WP pin and BP bits, OTP-locked security registers for cryptographic keys, 64-bit unique ID for device binding, and SFDP-based parameter auto-discovery to ensure correct timing during field updates - all confirmed in the official datasheet Revision E.
