Product details
Overview
W25Q128JWSIM TR from Winbond is a 128M-bit (16MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 1.7–1.95V supply, -40°C to +105°C industrial-plus grade operation, 133MHz Quad I/O clock, and uniform 4KB sector erase architecture - used for XIP code execution, firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q128JWSIM TR datasheet, W25Q128JWSIM TR pinout, W25Q128JWSIM TR application, or W25Q128JWSIM TR equivalent, this page delivers verified pin functions, real-world timing performance (532MHz equivalent Quad I/O), JEDEC-compliant SFDP support, hardware /WP and /HOLD control, and validated alternatives for industrial-grade flash replacement.
Technical Context
The W25Q128JWSIM TR implements a quad-I/O SPI interface requiring non-volatile QE bit (Status Register-2) enablement; IO0–IO3 operate bidirectionally during Quad SPI reads (e.g., Fast Read Quad I/O 0xEB), while /WP and /HOLD serve dual roles - /WP becomes IO2 and /HOLD becomes IO3 when QE=1. Standard SPI uses unidirectional DI/DO; Dual SPI uses bidirectional IO0/IO1.
It features volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP, QE, WPS, DRV1/DRV0), 64-bit unique ID, 3×256-byte OTP-lockable security registers, and Erase/Program Suspend & Resume functionality - all supported across SOIC, WSON, TFBGA, and WLCSP packages with identical core instruction set and timing behavior.

Pinout & Package
W25Q128JWSIM TR is supplied in an 8-pin SOIC 208-mil package (Package Code S), with no dedicated /RESET pin - /HOLD pin (Pin 7) serves dual function as /HOLD in Standard/Dual SPI mode and IO3 in Quad SPI mode when QE=1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; device enters high-impedance output state and standby current (~1 µA) when high |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad SPI - supports Fast Read Dual/Quad Output |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write-protection active low; becomes IO2 in Quad SPI when QE=1 - enables full 4-line data bus |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-impedance PCB connection to minimize noise coupling |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad SPI - carries instructions, addresses, and data |
| 6 CLK | Serial Clock Input | Synchronous timing reference for all SPI operations; supports Mode 0 and Mode 3; max 133 MHz in Quad I/O |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write when low (active); becomes IO3 in Quad SPI when QE=1 - critical for multi-device bus sharing |
| 8 VCC | Power Supply | 1.7–1.95 V nominal supply; internal voltage regulator enables stable core operation across rail variation |

FAQ
What is the supply voltage range for the W25Q128JWSIM TR?
The W25Q128JWSIM TR operates from 1.7 V to 1.95 V. This narrow 1.8V nominal range enables ultra-low power consumption (1 mA active, <1 µA power-down) and compatibility with modern low-voltage SoCs and microcontrollers. Operation outside this range may cause undefined behavior or data corruption - always verify VCC stability during power-up sequencing per Section 9.3 of the datasheet.
Does the W25Q128JWSIM TR support hardware reset via /RESET pin?
No, the W25Q128JWSIM TR does not include a dedicated /RESET pin. It is packaged in 8-pin SOIC 208-mil (Package Code S), which omits /RESET. Hardware reset is only available on SOIC-16 (F) and TFBGA (B/C) variants. For W25Q128JWSIM TR, system-level reset must be implemented via software sequence: Enable Reset (0x66) followed by Reset Device (0x99), completing in ~30 µs.
How is Quad SPI mode enabled on the W25Q128JWSIM TR?
Quad SPI mode is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2). This is done using Write Status Register-2 (0x31) with value 0x02. Once QE=1, pins /WP (Pin 3) and /HOLD (Pin 7) become IO2 and IO3 respectively, enabling 4-line bidirectional data transfer. The QE bit can be configured as volatile or non-volatile depending on SR2's SRP1/SRP0 settings.
What package type is used for the W25Q128JWSIM TR?
The W25Q128JWSIM TR uses an 8-pin SOIC 208-mil package (Package Code S), measuring 5.3 mm × 5.3 mm × 1.95 mm. This compact, surface-mount package supports reflow soldering and is compatible with standard PCB assembly processes. Pin 1 is marked with a notch or dot; orientation follows JEDEC MS-012 standards.
Can the W25Q128JWSIM TR be used for Execute-in-Place (XIP) applications?
Yes, the W25Q128JWSIM TR supports XIP via Dual and Quad SPI interfaces. Its 133 MHz Quad I/O clock enables up to 532 MB/s effective bandwidth, allowing ARM Cortex-M/A-series processors to execute code directly from flash with minimal latency. Fast Read Quad I/O (0xEB) and Set Burst with Wrap (0x77) instructions optimize sequential fetch performance for XIP use cases.
