Product details
Overview
W25Q16DVSSJP 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 W25Q16DVSSJP TR datasheet, W25Q16DVSSJP TR pinout, W25Q16DVSSJP TR application, or W25Q16DVSSJP TR equivalent, this page delivers verified package mapping (8-pin SOIC 208-mil), confirmed Quad SPI pin reassignment logic (IO0–IO3), JEDEC ID compliance, sector/block erase granularity, and real-world XIP timing behavior - all validated against Winbond's Revision K datasheet (May 2016).
Technical Context
The W25Q16DVSSJP TR implements a SPI-compatible command set with hardware- and software-based write protection, including top/bottom 4 KB sector lock, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, QE), and 64-bit unique ID. Its block diagram integrates a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP locks.
Quad SPI operation requires explicit setting of the non-volatile Quad Enable (QE) bit in Status Register-2; when enabled, /WP and /HOLD become IO2 and IO3, disabling their hardware protection functions. The device supports SPI modes 0 and 3, with hold/resume functionality during active selection and erase/program suspend capability for concurrent background operations.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = high-impedance DO, low = active SPI communication; must transition high→low after power-up before first instruction |
| 2 DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard/Dual SPI; bidirectional I/O in Quad SPI; used for Fast Read instructions and status reads |
| 3 /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware lock for status register when QE=0; becomes IO2 in Quad SPI (QE=1), disabling hardware WP function |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance connection to system ground plane |

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), 104 MHz max clock, but lacks Quad SPI I/O reassignment; /WP and /HOLD remain dedicated pins regardless of QE state | Preferred where hardware write protection must remain active alongside Quad SPI use - e.g., dual-role security+performance designs | Select MX25L1606EZN-12G if /WP and /HOLD hardware functions cannot be sacrificed for Quad I/O bandwidth. |
| S25FL116K0XMFI041 | 16 M-bit, 85 MHz max clock, supports Quad SPI but uses different status register layout (CR1/CR2 instead of SR1/SR2) and lacks SFDP register | Better suited for legacy BSPs without SFDP auto-detection; lower clock ceiling limits XIP performance in high-throughput applications | Choose S25FL116K0XMFI041 only when migrating from Cypress platforms with existing driver stacks and no need for >85 MHz bandwidth. |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI041, W25Q16DVSSJP TR delivers higher Quad SPI bandwidth (104 MHz vs. 85 MHz), integrated SFDP for plug-and-play driver compatibility, and finer 4 KB sector granularity - making it optimal for new designs prioritizing XIP latency, security flexibility, and automated configuration.

FAQ
What is the package type and lead pitch of W25Q16DVSSJP TR?
W25Q16DVSSJP TR uses an 8-pin SOIC 208-mil package (package code SS) with gull-wing leads and a 1.27 mm lead pitch. This footprint complies with JEDEC MS-012AC and is compatible with standard reflow profiles for leaded packages. The "SS" suffix in the part number explicitly denotes the 208-mil body width variant.
Does W25Q16DVSSJP TR support true execute-in-place (XIP) operation?
Yes, W25Q16DVSSJP TR supports true XIP via its Continuous Read Mode, which requires only 8 clock cycles to initiate a read after address setup and supports wrap lengths of 8/16/32/64 bytes. When paired with a host controller that supports Quad SPI I/O and has appropriate prefetch buffering, W25Q16DVSSJP TR enables direct code execution without RAM shadowing - validated in Winbond's application notes AN101 and AN107.
How does the Quad Enable (QE) bit affect pin functionality on W25Q16DVSSJP TR?
When the Quad Enable (QE) bit in Status Register-2 is set to 1, W25Q16DVSSJP TR reassigns /WP (pin 3) to IO2 and /HOLD (pin 7) to IO3 to enable full Quad SPI operation. This disables hardware write protection and hold functionality. To retain /WP or /HOLD, QE must remain cleared (0), limiting operation to Standard or Dual SPI modes only.
What is the minimum erase unit size supported by W25Q16DVSSJP TR?
W25Q16DVSSJP TR supports a minimum erase unit of 4 KB - implemented as uniform sectors (512 total). This granularity allows precise firmware partitioning (e.g., separate bootloader, application, and configuration sectors) and minimizes unnecessary wear during field updates, unlike larger-block-only alternatives.
Is W25Q16DVSSJP TR compliant with JEDEC JESD216 for SFDP?
Yes, W25Q16DVSSJP TR implements a JEDEC JESD216-compliant SFDP register accessible via instruction 5Ah. The register contains versioned parameter tables for clock frequency, voltage range, erase block sizes, and Quad SPI capabilities - enabling automatic driver initialization in Linux MTD, Zephyr, and other modern RTOS/BSP frameworks without hard-coded assumptions.
