Product details
Overview
W25Q128JWFIM TR from Winbond is a 1.7–1.95V, 128M-bit (16MB) serial NOR flash memory with Dual/Quad SPI, QPI, and DTR read support, organized into 65,536 × 256-byte pages and 4,096 uniform 4KB sectors. It delivers up to 133MHz Quad I/O clocking, enabling 532MHz equivalent throughput and 66MB/s continuous read, targeting code execution (XIP), firmware storage, and secure parameter retention in space-constrained industrial systems.
For engineers reviewing the W25Q128JWFIM TR datasheet, W25Q128JWFIM TR pinout, W25Q128JWFIM TR application, or W25Q128JWFIM TR equivalent, key selection criteria include its 1.8V operation, hardware /WP and /HOLD pins (SOIC-8), quad-enable status register control, 100K program-erase cycles, and JEDEC-compliant SFDP register for auto-configuration.
Technical Context
The W25Q128JWFIM TR implements a flexible SPI-compatible command set supporting Standard, Dual, Quad, and QPI modes - with DTR (Double Transfer Rate) read instructions enabled via Status Register-2 QE bit. Its architecture includes three 256-byte one-time-programmable (OTP) security registers, 64-bit unique ID, and programmable output driver strength (DRV1/DRV0).
It supports erasable granularity of 4KB sectors, 32KB blocks, and 64KB blocks, plus chip erase; features suspend/resume for erase/program operations; and provides volatile/non-volatile write protection via BP2–BP0, TB, SEC, CMP, and SRP bits - all configurable through dedicated SPI instructions like 01h, 31h, and 11h.

Pinout & Package
W25Q128JWFIM TR uses an 8-pin SOIC 208-mil package (Package Code S), with no dedicated /RESET pin - /HOLD (Pin 7) serves dual function as /HOLD or /RESET depending on Status Register configuration when QE=0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable; places DO in high-Z when deasserted; required to transition H→L before instruction acceptance |
| DO / IO1 (Pin 2) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes when QE=1 |
| /WP / IO2 (Pin 3) | Write Protect Input / Quad I/O Line 2 | Hardware write-protection for status register; repurposed as IO2 in Quad mode (QE=1) |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and I/O signals; must be low-impedance for timing integrity |
| DI / IO0 (Pin 5) | Data Input / Quad I/O Line 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes when QE=1 |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI operations; max 133 MHz in Quad I/O |
| /HOLD or /RESET (Pin 7) | Hold or Reset Input / Quad I/O Line 3 | Pauses ongoing operation when active low; configurable as /RESET only if QE=0; becomes IO3 in Quad mode |
| VCC (Pin 8) | Power Supply | 1.7–1.95 V supply; powers core logic, charge pumps, and I/O buffers |
Key Features
| Feature | Design Value |
|---|---|
| DTR Read Support | Enables double-data-rate reads (e.g., 0Dh, BDh, EDh) - doubles effective throughput without increasing clock frequency |
| QPI Mode | Reduces instruction overhead via 4-bit-wide command/address/data bus - enables true XIP with minimal CPU intervention |
| Erase/Program Suspend | Allows background operation pause (75h) and resume (7Ah) - critical for real-time systems requiring deterministic latency |
| Flexible Write Protection | Combines hardware (/WP, /HOLD) and software (BPx, TB, SEC, CMP) controls - enables hierarchical, field-updatable memory lockdown |
| Discoverable Parameters | SFDP register (5Ah) provides standardized, versioned memory map and timing parameters - eliminates hard-coded configuration |

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 |
|---|---|---|---|
| MX25L12835FZC-10G | 3V supply (2.7–3.6V); no DTR support; 104MHz max Quad SPI clock; lacks SFDP register | Requires level-shifting in 1.8V systems; no auto-configuration; lower bandwidth limits XIP performance | Select only if legacy 3V design compatibility or cost sensitivity outweighs 1.8V integration and DTR benefits |
| S25FL128SAGMFI000 | 1.8V supply; supports DTR; includes on-die ECC; 80MHz max Quad SPI clock; Cypress/Infineon SFDP v1.6 | Higher reliability for mission-critical storage but lower throughput than W25Q128JWFIM TR's 133MHz | Prefer when ECC-enabled data integrity is mandatory and 66MB/s read rate is not required |
Compared with MX25L12835FZC-10G and S25FL128SAGMFI000, the W25Q128JWFIM TR uniquely combines 133MHz Quad I/O, DTR read, SFDP v1.7, and Industrial Plus temperature range in a single 1.8V SOIC-8 package - making it optimal for next-generation embedded systems demanding speed, configurability, and ruggedness without voltage translation.

FAQ
What is the supply voltage range for W25Q128JWFIM TR?
The W25Q128JWFIM TR operates exclusively within a 1.7V to 1.95V supply range, making it compatible with 1.8V system rails. It does not support 3.3V or wider voltage ranges. This tight tolerance ensures low-power operation and thermal stability in Industrial Plus applications up to +105°C.
Does W25Q128JWFIM TR support hardware reset via a dedicated pin?
No - W25Q128JWFIM TR uses an 8-pin SOIC package without a dedicated /RESET pin. Pin 7 functions as /HOLD by default, and can be configured as /RESET only when the Quad Enable (QE) bit in Status Register-2 is cleared (QE=0). When QE=1, Pin 7 becomes IO3 for Quad SPI operation.
How does W25Q128JWFIM TR implement write protection?
W25Q128JWFIM TR provides layered write protection: hardware-level via /WP pin (active-low, disabled in Quad mode), and software-level via status register bits (BP2–BP0, TB, SEC, CMP, SRP). These can be set independently to protect sectors, blocks, or the entire array - with non-volatile settings retained after power loss.
What is the significance of DTR support in W25Q128JWFIM TR?
DTR (Double Transfer Rate) in W25Q128JWFIM TR enables two data bits per clock edge during read operations (e.g., instructions 0Dh, BDh, EDh), effectively doubling throughput without raising clock frequency. This reduces EMI and timing margin pressure while maintaining 66MB/s sustained read rates in high-speed XIP applications.
Can W25Q128JWFIM TR be used for execute-in-place (XIP) applications?
Yes - W25Q128JWFIM TR supports true XIP via Quad SPI and QPI modes, with DTR read instructions and low-latency burst access. Its 133MHz Quad I/O clock and 4KB uniform sector architecture enable deterministic code fetch timing, making it suitable for direct execution in microcontrollers lacking internal flash or requiring external code expansion.
