Product details
Overview
W25Q16JVZPIQ 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 and is used for code storage, XIP execution, and firmware parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q16JVZPIQ TR datasheet, W25Q16JVZPIQ TR pinout, W25Q16JVZPIQ TR application, or W25Q16JVZPIQ TR equivalent, key selection considerations include Quad SPI enable (QE bit), /HOLD vs. /RESET pin behavior in SOIC-8 vs. WSON packages, 4 KB sector erase granularity, JEDEC ID and SFDP register compliance, and OTP-locked security register support.
Technical Context
The W25Q16JVZPIQ TR implements a quad I/O SPI interface requiring non-volatile QE bit (Status Register-2, bit 1) to be set to repurpose /WP and /HOLD as IO2 and IO3. It supports SPI modes 0 and 3, with continuous read wrap (8/16/32/64-byte) enabling true execute-in-place (XIP) operation without address retransmission.
Its flexible protection architecture includes volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP), individual 4 KB sector locks (32 sectors), and three 256-byte OTP-locked security registers. Erase suspend/resume and power-down (<1 µA typical) support low-power system states.

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 |
|---|---|---|---|
| MX25L1606EZUI-12G | 16 M-bit, 104 MHz max clock, no Quad I/O; uses standard SPI only; lacks SFDP and unique ID | No XIP acceleration beyond 104 MHz; no hardware-assisted sector locking or security registers | Choose for cost-sensitive designs where Quad SPI and security features are unnecessary |
| S25FL116K0XMFI011 | 16 M-bit, 80 MHz max clock, Quad SPI supported; includes configurable dummy cycles and deep power-down mode | Lower bandwidth limits XIP performance; deeper sleep current (100 nA vs. 1 µA) benefits battery-powered devices | Prefer when ultra-low standby power outweighs speed requirements and Winbond ecosystem integration |
Compared with MX25L1606EZUI-12G and S25FL116K0XMFI011, the W25Q16JVZPIQ TR delivers higher throughput (133 MHz → 532 MHz quad), finer 4 KB sector control, and integrated security registers - making it optimal for XIP-capable, firmware-secure embedded systems requiring field upgrade resilience.

FAQ
Does W25Q16JVZPIQ TR support hardware reset (/RESET pin)?
No, the W25Q16JVZPIQ TR in the WSON 6×5-mm (ZP) package does not include a dedicated /RESET pin. The /HOLD pin (Pin 7) serves only as a hold input or IO3 in Quad mode. Hardware reset is available only in SOIC-16 and TFBGA packages per Winbond documentation. For W25Q16JVZPIQ TR, software reset via 66h+99h instructions is the supported method.
What is the function of the /WP pin on W25Q16JVZPIQ TR?
On W25Q16JVZPIQ TR, the /WP pin (Pin 3) functions as a hardware write protect input in Standard and Dual SPI modes, preventing writes to the status register when asserted low. When Quad SPI is enabled (QE=1), this pin becomes IO2 for bidirectional data transfer. Its dual role requires careful configuration of the QE bit before switching interface modes.
How many 4 KB sectors does W25Q16JVZPIQ TR contain?
The W25Q16JVZPIQ TR contains exactly 512 uniform 4 KB sectors, totaling 2,097,152 bytes (16 M-bit). Each sector can be independently erased, programmed, and locked using the Individual Block Lock feature (39h/36h instructions), enabling fine-grained firmware partitioning and secure update mechanisms.
Is W25Q16JVZPIQ TR compatible with JEDEC-standard SFDP?
Yes, W25Q16JVZPIQ TR fully supports the JEDEC JESD216 standard Serial Flash Discoverable Parameters (SFDP) register, accessible via instruction 5Ah. This allows automatic configuration of read latencies, dummy cycles, and Quad SPI settings by host bootloaders without hard-coded timing parameters.
What is the minimum power-down current for W25Q16JVZPIQ TR?
The W25Q16JVZPIQ TR achieves a typical power-down current of less than 1 µA at VCC = 3.0 V and TA = +25°C, as specified in Section 10.4 of the datasheet. This ultra-low standby draw supports energy-sensitive applications such as battery-backed IoT nodes and portable medical devices requiring extended sleep duration.
