Product details
Overview
W25Q16JVZPJQ from Winbond is a 16 M-bit (2 MB) Serial Flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock frequency, 4 KB uniform sector architecture, and single 2.7–3.6 V supply - deployed for code shadowing, XIP execution, and firmware storage in space-constrained embedded systems.
For engineers reviewing the W25Q16JVZPJQ datasheet, W25Q16JVZPJQ pinout, W25Q16JVZPJQ application, or W25Q16JVZPJQ equivalent, key selection criteria include Quad SPI enable (QE bit), /HOLD vs. /RESET pin behavior per package, 4 KB sector granularity, JEDEC ID (EF4015), and SFDP register support for configurable timing and command sets.
Technical Context
The W25Q16JVZPJQ implements a SPI-compatible serial interface with Mode 0 and Mode 3 clock polarity support, enabling interoperability with standard microcontroller SPI peripherals. Its internal architecture includes three status registers (SR1–SR3), non-volatile Quad Enable (QE) bit in SR2, and volatile/non-volatile block protect bits (BP2–BP0, TB, SEC, CMP) for flexible memory protection.
It supports hardware write protection via active-low /WP and /HOLD pins (reconfigured as IO2/IO3 in Quad mode), erase/program suspend/resume functionality, and 64-bit unique ID per device. The /RESET pin is not present on this SOIC-8 variant - reset relies solely on software sequence (66h + 99h).

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EZN-12G | Same density (16 M-bit), 104 MHz max clock, no Quad I/O; supports only Standard/Dual SPI | Lacks QE bit and IO2/IO3 - cannot execute Fast Read Quad I/O (EBh) or Quad Page Program (32h) | Select when Quad bandwidth is unnecessary and legacy Dual SPI compatibility is prioritized |
| AT25SF161-SSHD-B | 16 M-bit, 104 MHz, Quad SPI enabled by default; includes hardware reset pin in SOIC-8 package | Integrates dedicated /RESET pin (not present on W25Q16JVZPJQ), simplifying system-level reset coordination | Choose when deterministic hardware reset is required and JEDEC SFDP compliance is acceptable |
Compared with MX25L1606EZN-12G and AT25SF161-SSHD-B, W25Q16JVZPJQ delivers higher throughput (133 MHz vs. 104 MHz), broader instruction set (including Set Burst with Wrap 77h), and deeper security (3×256-byte OTP-locked registers), making it optimal for performance- and security-sensitive embedded firmware.

FAQ
Does W25Q16JVZPJQ support hardware reset via /RESET pin?
No, W25Q16JVZPJQ does not include a hardware /RESET pin. It uses an 8-pin SOIC-208-mil package (Code SS), which lacks the dedicated /RESET terminal. Reset must be performed using the software sequence: Enable Reset (66h) followed by Reset Device (99h), completing in ~30 µs. This is confirmed in Section 4.1 and Note 1 of the datasheet revision G.
What is the function of Pin 7 (/HOLD or /RESET) on W25Q16JVZPJQ?
On W25Q16JVZPJQ, Pin 7 functions exclusively as /HOLD - an active-low input that pauses ongoing read/write operations while /CS remains low. It does not serve as /RESET, as that function is absent in this SOIC-8 variant. When Quad SPI is enabled (QE=1), Pin 7 becomes IO3. This behavior is explicitly defined in Section 3.3 and Figure 1a of the datasheet.
How is Quad SPI enabled on W25Q16JVZPJQ?
Quad SPI is enabled on W25Q16JVZPJQ by setting the non-volatile Quad Enable (QE) bit in Status Register-2 (SR2). This is done via Write Status Register-2 (31h) after issuing Write Enable (06h). Once QE=1, Pins 3 (/WP) and 7 (/HOLD) become IO2 and IO3 respectively, allowing full Quad I/O operation including Fast Read Quad I/O (EBh) and Quad Page Program (32h).
What JEDEC ID and SFDP support does W25Q16JVZPJQ provide?
W25Q16JVZPJQ returns JEDEC ID EF4015 (Manufacturer ID EFh, Device ID 4015h) via Read JEDEC ID (9Fh) and supports the Serial Flash Discoverable Parameters (SFDP) register (5Ah), which contains standardized timing, command, and feature descriptors. This enables automatic driver initialization on modern SoCs like NXP i.MX and STMicro STM32H7 with QSPI peripherals.
Can W25Q16JVZPJQ be used for secure boot key storage?
Yes, W25Q16JVZPJQ includes three 256-byte Security Registers (SR1–SR3) with One-Time-Programmable (OTP) lock bits (LB1–LB3) that permanently prevent further writes once set. These registers are electrically isolated from main memory and support cryptographic key storage, device-specific certificates, and calibration data - verified in Sections 2, 7, and 9.3 of the datasheet.
