Product details
Overview
W25Q16DVSSJG 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-ready continuous read mode. It operates from 2.7–3.6 V, draws 4 mA active current and 1 µA in power-down, and targets embedded code storage, firmware boot, and parameter retention in space-constrained MCU systems.
For engineers reviewing the W25Q16DVSSJG TR datasheet, W25Q16DVSSJG TR pinout, W25Q16DVSSJG TR application, or W25Q16DVSSJG TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector erase granularity, hardware write protection via /WP and /HOLD pins, and compatibility with SPI Mode 0/3 for microcontroller interface validation.
Technical Context
The W25Q16DVSSJG TR implements a unified SPI command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD only after setting the non-volatile Quad Enable (QE) bit in Status Register-2. Its internal architecture includes a 256-byte page buffer, 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks.
It supports JEDEC-standard manufacturer/device ID (90h/9Fh), 64-bit unique serial number (4Bh), SFDP register (5Ah), and three 256-byte security registers with OTP locks. Erase/program suspend/resume (75h/7Ah) enables concurrent background operations, while continuous read mode reduces instruction overhead to 8 clocks per 24-bit address access.

Pinout & Package
W25Q16DVSSJG TR uses an 8-pin SOIC 208-mil (package code SS) with standard SPI pinout and dual/quad I/O multiplexing. Pin functions are defined by instruction mode and QE bit state.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO output when deasserted; required low-to-high transition before new instruction acceptance |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Standard SPI output (DO); becomes bidirectional IO1 in Dual/Quad mode; used for Fast Read Dual/Quad Output instructions |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write lock for status register when QE=0; remapped to IO2 in Quad mode (QE=1); not available during Quad operation |
| 4 GND | Ground Reference | Signal and power return path; must be low-impedance for stable SPI timing and noise immunity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input (DI); becomes bidirectional IO0 in Dual/Quad mode; carries instructions, addresses, and data on CLK rising edge |
| 6 CLK | Serial Clock Input | Edge-triggered timing source; supports SPI Modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1); max 104 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses active SPI transaction when asserted low; remapped to IO3 in Quad mode (QE=1); disabled during Quad operation |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required near pin for transient current stability |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit enabling IO2/IO3 remapping - required for full 4-line data bus operation |
| Continuous Read Mode | 8-clock instruction overhead per 24-bit address - enables true execute-in-place (XIP) from flash without RAM copy |
| Erase/Program Suspend | 75h/7Ah commands allow pausing ongoing erase/program to service urgent reads - critical for real-time systems |
| 64-bit Unique ID | Factory-programmed serial number (4Bh instruction) - enables device-level traceability and secure firmware binding |
| Security Registers | Three 256-byte OTP-locked registers (42h/44h/48h) - store cryptographic keys or calibration data with permanent write protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM2I-12G | Same density (16 M-bit), 3.3 V, SOIC 208-mil, but lacks Quad SPI and SFDP; max SPI clock 86 MHz | No XIP-optimized continuous read or Quad I/O - limited to legacy SPI-only MCUs | Select when Quad SPI is unnecessary and cost sensitivity outweighs performance needs |
| S25FL116K0XMFI011 | 16 M-bit, 3.0 V min, SOIC 208-mil, supports Quad SPI and SFDP, but no security registers or OTP locks | Lacks hardware-secured storage - unsuitable for calibration or cryptographic key storage | Choose for general-purpose firmware storage where security features are not required |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI011, the W25Q16DVSSJG TR delivers higher bandwidth (104 MHz vs ≤86 MHz), integrated security registers with OTP, and superior XIP efficiency via continuous read mode - making it optimal for secure, high-performance embedded boot and code storage.

FAQ
What is the package type and lead count of the W25Q16DVSSJG TR?
The W25Q16DVSSJG TR uses an 8-pin SOIC 208-mil (package code SS) surface-mount package with standard gull-wing leads. This package is RoHS-compliant, moisture-sensitive level 3 (MSL3), and rated for industrial temperature range (-40°C to +85°C). The pinout matches other W25Q-series SOIC variants, enabling drop-in replacement within the same package footprint.
Does the W25Q16DVSSJG TR support execute-in-place (XIP) operation?
Yes, the W25Q16DVSSJG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to just 8 clock cycles for addressing - enabling direct code execution from flash without RAM loading. This requires enabling Quad SPI mode (QE=1) and using Fast Read Quad I/O (EBh) or Word Read Quad I/O (E7h) instructions for optimal throughput.
How is hardware write protection implemented on the W25Q16DVSSJG TR?
The W25Q16DVSSJG TR implements hardware write protection through the /WP pin (Pin 3), which-when held low-prevents writes to the status register. This works in conjunction with status register bits (BP2–BP0, TB, SEC) to protect sectors or blocks. When Quad SPI is enabled (QE=1), /WP is remapped to IO2 and hardware protection is disabled; software-based protection via status register bits remains active.
What is the role of the /HOLD pin on the W25Q16DVSSJG TR?
The /HOLD pin (Pin 7) allows pausing an active SPI transaction while /CS is low: asserting /HOLD low places DO in high-impedance and ignores DI/CLK inputs. This is essential when sharing the SPI bus among multiple devices. In Quad SPI mode (QE=1), /HOLD is remapped to IO3 and the hold function is disabled - software-controlled transaction management must then be used instead.
Can the W25Q16DVSSJG TR be used with microcontrollers that only support standard SPI (not Dual/Quad)?
Yes, the W25Q16DVSSJG TR is fully backward-compatible with standard SPI (Mode 0 or Mode 3) using DI (Pin 5), DO (Pin 2), /CS (Pin 1), and CLK (Pin 6). All core functionality-including read, program, and erase-is accessible without enabling Dual or Quad modes. The /WP and /HOLD pins remain active for hardware protection and bus arbitration in this configuration.
