Product details
Overview
W25Q128FWPIQ from Winbond is a 1.8V, 128M-bit (16MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces. It features 4KB uniform sectors, 104MHz max clock frequency, and true execute-in-place (XIP) capability via Continuous Read Mode. It is used for code storage and firmware boot in space-constrained embedded systems such as IoT edge nodes and industrial controllers.
For engineers reviewing the W25Q128FWPIQ datasheet, W25Q128FWPIQ pinout, W25Q128FWPIQ application, or W25Q128FWPIQ equivalent, key selection criteria include quad I/O timing compliance, 1.65–1.95V supply tolerance, sector-level write protection granularity, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q128FWPIQ implements a multi-mode serial interface with configurable I/O count: standard SPI (4-wire), dual I/O (5-wire), quad I/O (6-wire), and QPI (6-wire with 2-cycle instruction encoding). Its internal architecture includes a 256-byte page buffer, 4KB sector erase granularity, and three 256-byte one-time-programmable (OTP) security registers.
Operation relies on volatile/non-volatile status register bits-including Quad Enable (QE), Write Protect Selection (WPS), and HOLD/RESET function control-to configure interface mode and hardware protection. Erase/program suspend/resume functionality enables concurrent background operations without interrupting host access.

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 |
|---|---|---|---|
| MX25L12833FZC-10G | 3V supply (2.7–3.6V), no QPI mode, 80MHz max clock, 1.8V I/O compatible only | Requires level-shifting for 1.8V hosts; lacks QPI efficiency and SFDP auto-configuration | Select only if legacy 3V system compatibility is mandatory and Quad I/O bandwidth is not required |
| S25FL128SAGMFI000 | 1.8V supply, 133MHz clock, HyperBus interface option, no /HOLD pin in 8-pin variant | Higher bandwidth but incompatible pinout and protocol; requires HyperFlash controller or FPGA IP | Choose for performance-critical designs needing >500MB/s throughput and willing to adopt HyperBus ecosystem |
Compared with MX25L12833FZC-10G and S25FL128SAGMFI000, the W25Q128FWPIQ uniquely balances 1.8V native operation, QPI efficiency, SFDP configurability, and pin-compatible support across SOIC/WSON/TFBGA packages - making it optimal for cost-sensitive, space-constrained 1.8V embedded systems requiring field-upgradable firmware.

FAQ
What interface protocols does the W25Q128FWPIQ support?
The W25Q128FWPIQ supports Standard SPI (4-wire), Dual SPI (5-wire), Quad SPI (6-wire), and Quad Peripheral Interface (QPI) modes. QPI mode is enabled by setting the Quad Enable (QE) bit in Status Register-2 and using the 0x38 instruction. All modes operate within the same 1.65–1.95V supply range and share identical pin assignments in the 8-pin SOIC package.
Does the W25Q128FWPIQ support execute-in-place (XIP) operation?
Yes, the W25Q128FWPIQ supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles for address setup. When combined with Quad I/O or QPI read instructions (e.g., 0xEB or 0x0B), it delivers deterministic, low-latency code execution directly from flash-eliminating the need for full firmware copying to RAM before execution.
How is hardware write protection implemented on the W25Q128FWPIQ?
Hardware write protection on the W25Q128FWPIQ uses the /WP pin in conjunction with non-volatile 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. Protection granularity ranges from individual 4KB sectors to the full array, and the /WP pin is disabled in Quad I/O mode (QE=1) since it becomes IO2.
What is the purpose of the /HOLD and /RESET functions on the W25Q128FWPIQ?
The /HOLD pin pauses ongoing operations (e.g., read/write) while maintaining internal state, allowing shared SPI bus arbitration. The /RESET pin performs a hardware reset, clearing internal logic and reinitializing the status register. In the 8-pin SOIC package (like W25Q128FWPIQ), /HOLD and /RESET share the same physical pin (IO3) and are selected via the HOLD/RST bit in Status Register-3; the dedicated /RESET pin exists only in 16-pin SOIC variants.
Can the W25Q128FWPIQ be used in automotive applications?
The W25Q128FWPIQ is rated for –40°C to +85°C operation and offers 20-year data retention and 100,000 erase/program cycles-meeting baseline reliability requirements for many automotive infotainment and body-control modules. However, it is not AEC-Q100 qualified; for ASIL-B/C safety-critical applications, Winbond's automotive-grade W25Q128JW (AEC-Q100 Grade 3) is the designated alternative.
