Product details
Overview
W25Q16JVZPJQ TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock frequency, 4 KB uniform sector architecture, and hardware/software write protection. It operates from 2.7–3.6 V, draws <1 µA in power-down mode, and targets embedded code storage, XIP execution, and firmware parameter retention in space-constrained industrial and consumer systems.
For engineers reviewing the W25Q16JVZPJQ TR datasheet, W25Q16JVZPJQ TR pinout, W25Q16JVZPJQ TR application, or W25Q16JVZPJQ TR equivalent, key selection criteria include Quad SPI enable (QE bit), /WP and /HOLD pin functionality in SOIC-8, 4 KB sector granularity for data partitioning, JEDEC ID and SFDP register support for auto-configuration, and 100K program-erase cycle endurance per sector.
Technical Context
The W25Q16JVZPJQ TR implements a quad I/O SPI interface requiring non-volatile setting of the QE bit in Status Register-2 to repurpose /WP and /HOLD as IO2 and IO3. Its block diagram includes a 256-byte page buffer, 512 × 4 KB erasable sectors, and three status registers with volatile/non-volatile control bits for BP, TB, SEC, CMP, SRP, and SUS functions.
It supports SPI modes 0 and 3, features erase/program suspend-resume capability, and integrates three 256-byte OTP-locked security registers. The /RESET function is software-only on this SOIC-8 variant-no dedicated hardware reset pin is present, distinguishing it from SOIC-16 or TFBGA packages.

Pinout & Package
W25Q16JVZPJQ TR is supplied in an 8-pin SOIC-208-mil package (Package Code SS), with gull-wing leads and standard JEDEC MS-012AC footprint. Pin 1 is /CS; pins 2–3–5–7 are bidirectional I/Os configurable for SPI modes; pin 4 is GND; pin 6 is CLK; pin 8 is VCC.

| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware write lock for status register when QE=0; becomes IO2 in Quad SPI (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-impedance PCB connection |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI; carries instructions, addresses, data |

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, 104 MHz max clock, no Quad I/O (only Dual SPI), no SFDP or unique ID | Lacks Quad SPI bandwidth and auto-discovery features; suitable only where legacy SPI drivers exist | Choose only if system lacks Quad SPI controller support and does not require SFDP or secure ID |
| S25FL116K0XMFI011 | 16 Mb, 85 MHz, supports Quad SPI but uses different QE mechanism (volatile bit); no security registers | Requires continuous QE re-enable after power cycle; no OTP-locked key storage capability | Select when cost sensitivity outweighs need for non-volatile QE and cryptographic key isolation |
Compared with W25Q16JVZPJQ TR, MX25L1606EZN-12G trades bandwidth and configurability for broad driver compatibility, while S25FL116K0XMFI011 offers simpler Quad SPI enablement but sacrifices security register isolation and 133 MHz performance headroom.

FAQ
Does W25Q16JVZPJQ TR support hardware reset via a dedicated /RESET pin?
No, W25Q16JVZPJQ TR does not include a hardware /RESET pin. This SOIC-208-mil variant relies solely on software reset using the Enable Reset (66h) followed by Reset Device (99h) instruction sequence. Dedicated /RESET is only available on SOIC-16 and TFBGA packages per Winbond's datasheet revision G. W25Q16JVZPJQ TR uses pin 7 exclusively as /HOLD (or IO3 in Quad mode), not /RESET.
What is the function of the /WP pin on W25Q16JVZPJQ TR in Quad SPI mode?
On W25Q16JVZPJQ TR, the /WP pin functions as IO2 (bidirectional data line) when the Quad Enable (QE) bit in Status Register-2 is set to 1. In this mode, hardware write protection is disabled for the /WP signal itself. Write protection must instead be managed via software-configured status register bits (BP, TB, SEC) or individual block locks. The /WP pin reverts to hardware write protect only when QE = 0.
Can W25Q16JVZPJQ TR be used for Execute-in-Place (XIP) applications?
Yes, W25Q16JVZPJQ TR supports true XIP operation via Fast Read Quad I/O (EBh) and Set Burst with Wrap (77h) instructions. Its 133 MHz Quad SPI clock enables up to 532 MB/s effective throughput, allowing direct CPU instruction fetch without intermediate RAM copy. The 4 KB uniform sector architecture also simplifies memory mapping for XIP-capable microcontrollers like ARM Cortex-M7 or RISC-V cores with QSPI peripherals.
How many program-erase cycles does W25Q16JVZPJQ TR guarantee per sector?
W25Q16JVZPJQ TR guarantees a minimum of 100,000 program-erase cycles per 4 KB sector, with greater than 20-year data retention at +25°C. This endurance rating is validated across the full industrial temperature range (–40°C to +85°C) and applies to all 512 sectors. Wear leveling must be implemented in firmware or host controller to achieve rated lifetime under frequent update workloads.
Is the 64-bit Unique ID in W25Q16JVZPJQ TR factory-programmed and read-only?
Yes, the 64-bit Unique ID in W25Q16JVZPJQ TR is factory-programmed during wafer test and permanently read-only. It is accessed via the Read Unique ID Number (4Bh) instruction and cannot be altered, erased, or reprogrammed. This ID provides deterministic device identification for secure boot, license binding, and field failure traceability - independent of main array contents or status register state.
