Product details
Overview
W25Q16CVSSJG 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 XIP-capable continuous read mode - deployed in embedded boot code storage, firmware update partitions, and parameter retention in industrial microcontroller systems.
For engineers reviewing the W25Q16CVSSJG TR datasheet, W25Q16CVSSJG TR pinout, W25Q16CVSSJG TR application, or W25Q16CVSSJG TR equivalent, this page delivers verified pin functions, JEDEC-compliant identification, Quad Enable (QE) bit behavior, 4 mA active current draw, and package-specific terminal mapping for SOIC-8 (150-mil, package code SN).
Technical Context
The W25Q16CVSSJG TR implements a SPI command-set architecture 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 block diagram integrates a 256-byte page buffer, sector/block erase logic, SFDP register, and three 256-byte security registers with OTP locks.
It supports SPI modes 0 and 3, features hardware write protection via /WP and /HOLD pins (active-low), and enables suspend/resume during erase/program cycles. The device uses internal high-voltage generators for programming and erasing, eliminating external VPP requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes), organized as 8,192 × 256-byte pages |
| Operating Voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V I/O domains without level shifting |
| Max Clock Frequency | 104 MHz for Dual/Quad SPI - enables 416 MB/s effective throughput in Quad I/O mode |
| Erase Granularity | Uniform 4 KB sectors (512 total), 32 KB blocks (32 total), 64 KB blocks (16 total), and full chip erase |
| Write Endurance | 100,000 program/erase cycles per sector - sufficient for firmware update logging and configuration storage |
| Data Retention | 20 years at +25°C - validated for long-life industrial deployments without refresh |
| Power Consumption | 4 mA active current (typ.), <1 µA power-down current (typ.) - suitable for battery-backed or low-power sleep states |
Pinout & Package
W25Q16CVSSJG TR is packaged in an 8-pin SOIC 150-mil (package code SN), with gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin finish. Pin 1 marked by notch or dot; pin 4 = GND, pin 8 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO/IOx to high-Z when high; required low-to-high transition after power-up before instruction acceptance |
| 2 DO (IO1) | Serial Data Output / Bidirectional I/O | Standard SPI output only; becomes IO1 in Dual/Quad mode - used for read data and status feedback |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE = 0; repurposed as IO2 in Quad mode (QE = 1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable SPI timing |
| 5 DI (IO0) | Serial Data Input / Bidirectional I/O | Standard SPI input only; becomes IO0 in Dual/Quad mode - carries instructions, addresses, and write data |
| 6 CLK | Serial Clock Input | Edge-triggered timing source for all SPI operations; supports Mode 0 and Mode 3; max 104 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write while /CS is low; repurposed as IO3 in Quad mode (QE = 1) |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit control | Enables 4-line bidirectional data transfer (IO0–IO3); QE must be set in Status Register-2 for persistent Quad operation |
| Continuous Read Mode | Reduces instruction overhead to 8 clocks for address setup - enables true execute-in-place (XIP) from flash without RAM copy |
| 4 KB uniform sector erase | Allows fine-grained firmware partitioning: bootloader, app code, and NV parameters each isolated in dedicated sectors |
| 64-bit unique ID | Factory-programmed per-device serial number accessible via 4Bh instruction - supports secure device authentication and traceability |
| SFDP register support | JEDEC JESD216-compliant Serial Flash Discoverable Parameters - enables automatic driver configuration in modern bootloaders |
| Security registers with OTP locks | Three 256-byte security registers, individually lockable via one-time-programmable bits - protects calibration data or keys from overwrite |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM1I-12G | Same density (16 M-bit), 3.3 V, SOIC-8, but supports only Standard/Dual SPI (no Quad I/O); max clock 80 MHz | Lacks Quad SPI and SFDP - unsuitable for XIP-critical or auto-configuring bootloaders | Select when cost sensitivity outweighs bandwidth needs and Quad functionality is unused |
| S25FL116K0XMFI041 | 16 M-bit, 3.0 V min, SOIC-8, supports Quad SPI and SFDP, but requires VIO pin (1.65–3.6 V) separate from VCC | Additional power rail complexity; no integrated security registers or OTP-locked regions | Prefer when dual-supply designs already exist and security register features are unnecessary |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, the W25Q16CVSSJG TR delivers higher throughput (104 MHz Quad), built-in security registers with OTP locks, and seamless SFDP integration - making it optimal for XIP-enabled, secure, and auto-configurable embedded systems.

FAQ
What is the package type and lead count of the W25Q16CVSSJG TR?
The W25Q16CVSSJG TR uses an 8-pin SOIC package with 150-mil body width (package code SN), featuring gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin plating. It is not a TFBGA, WSON, or PDIP variant - this exact part number maps exclusively to the SOIC-8 (150-mil) configuration per Winbond's ordering matrix.
Does the W25Q16CVSSJG TR support Quad SPI operation out of the box?
No - Quad SPI operation requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be explicitly set to '1' via Write Status Register (01h) instruction. Until configured, the device defaults to Standard SPI mode; /WP and /HOLD remain functional as hardware protect pins.
How does the W25Q16CVSSJG TR handle power-down and wake-up sequencing?
The W25Q16CVSSJG TR enters ultra-low-power state (<1 µA) upon receiving Power-down (B9h) instruction. Wake-up occurs automatically on next /CS low assertion - no external reset or voltage ramp monitoring is needed. /CS must track VCC during power transitions to avoid undefined behavior.
Can the W25Q16CVSSJG TR be used for execute-in-place (XIP) applications?
Yes - the W25Q16CVSSJG TR supports true XIP via Continuous Read Mode, which minimizes instruction overhead to just 8 clocks for address setup and enables efficient sequential access. Combined with 104 MHz Quad I/O, it delivers sustained bandwidth sufficient for direct code execution on Cortex-M and RISC-V cores.
What security features are implemented in the W25Q16CVSSJG TR?
The W25Q16CVSSJG TR includes hardware write protection (/WP pin), top/bottom sector locking via status register BP bits, volatile/non-volatile status register protection (SRP0/SRP1), and three 256-byte security registers with one-time-programmable (OTP) lock bits - enabling secure storage of calibration data, keys, or device-specific credentials.
