Product details
Overview
W25Q16FWZPIQ TR from Winbond is a 1.8V, 16M-bit serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, organized as 8192 × 256-byte pages with 4KB uniform sector erase, 32KB/64KB block erase, and chip erase - enabling code shadowing, XIP execution, and secure parameter storage in space-constrained embedded systems.
For engineers reviewing the W25Q16FWZPIQ TR datasheet, W25Q16FWZPIQ TR pinout, W25Q16FWZPIQ TR application, or W25Q16FWZPIQ TR equivalent, key selection criteria include 104MHz SPI clock support, Quad Enable (QE) bit configuration for IO2/IO3 remapping, JEDEC ID and SFDP register compliance, 1µA power-down current, and hardware write protection via /WP and /HOLD pins.
Technical Context
The W25Q16FWZPIQ TR implements a flexible SPI-compatible interface with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (2-clock instruction fetch). Its internal architecture includes volatile/non-volatile status registers (SR1–SR3), programmable block protect bits (BP2–BP0, TB, SEC), and a 64-bit unique ID register.
It supports erase/program suspend/resume, continuous read with wrap (8/16/32/64-byte), and configurable output driver strength (DRV1/DRV0). The /HOLD and /WP pins function as IO3 and IO2 respectively when QE=1, and revert to control functions when QE=0 - requiring explicit register initialization before Quad or QPI use.

Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per command vs. 8 in SPI - critical for low-latency XIP boot sequences |

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 | 3V supply (2.7–3.6V); no QPI mode; lacks SFDP register and security registers | Requires level-shifting in 1.8V systems; no standardized parameter discovery or OTP-locked security storage | Select only if legacy 3V design compatibility is required and security features are unused |
| S25FL116K0XMFI041 | 1.8V supply; supports QPI and SFDP; but only 16K program/erase cycles and no unique ID | Lower endurance limits field firmware update frequency; missing unique ID prevents device-level traceability | Prefer for cost-sensitive consumer applications where >100K cycles and device ID are non-critical |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, the W25Q16FWZPIQ TR delivers higher endurance, integrated security registers, JEDEC SFDP compliance, and true QPI mode - making it optimal for safety-certified, upgradable, and traceable embedded systems.

FAQ
What is the operating voltage range for the W25Q16FWZPIQ TR?
The W25Q16FWZPIQ TR operates from 1.65 V to 1.95 V. This narrow 1.8V nominal range ensures compatibility with modern low-power microcontrollers and eliminates the need for external level shifters in 1.8V system designs. Operation outside this range may cause undefined behavior or permanent damage, and the device is not rated for 3.3V or dual-supply operation.
Does the W25Q16FWZPIQ TR support execute-in-place (XIP) functionality?
Yes, the W25Q16FWZPIQ TR supports true XIP via Continuous Read Mode and Quad SPI or QPI interfaces. With as few as 8 clocks to address memory and Fast Read Quad I/O (EBh) achieving up to 50 MB/s, it enables direct CPU instruction fetch without intermediate RAM buffering - validated in ARM Cortex-M and RISC-V bootloaders.
How is hardware write protection implemented on the W25Q16FWZPIQ TR?
Hardware write protection on the W25Q16FWZPIQ TR uses the /WP pin in conjunction with status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). When /WP is held low and SRP bits are set, writes to protected sectors or the status register itself are blocked - independent of software commands. This provides tamper-resistant firmware lockdown during field operation.
What package type does the W25Q16FWZPIQ TR use, and is it RoHS compliant?
The W25Q16FWZPIQ TR uses an 8-pin WSON 6×5-mm package (ZP code) with wettable flanks and RoHS-compliant matte tin lead finish. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and supports reflow per IPC/JEDEC J-STD-020D.2, with no lead-free exemption required.
Can the W25Q16FWZPIQ TR be used in automotive applications?
The W25Q16FWZPIQ TR is rated for –40°C to +85°C operation and qualified to AEC-Q100 Grade 3. While not automotive-qualified out-of-box, its electrical specs, endurance (100K cycles), and data retention (>20 years) align with many infotainment and body-control module requirements - subject to full system-level qualification per OEM specifications.
