Product details
Overview
W25Q128FVSJP TR from Winbond is a 128M-bit (16MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, operating from 2.7V to 3.6V with 104MHz max clock, 4KB uniform sector erase, and 256-byte page programming - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q128FVSJP TR datasheet, W25Q128FVSJP TR pinout, W25Q128FVSJP TR application, or W25Q128FVSJP TR equivalent, this page delivers verified package mapping (8-pin SOIC 208-mil), confirmed pin functions (/CS, CLK, DI/DO/IO0–IO3, /WP, /HOLD), JEDEC ID support, SFDP register compliance, and real-world timing behavior for Fast Read Quad I/O (EBh) and Chip Erase (C7h).
Technical Context
The W25Q128FVSJP TR implements a quad I/O architecture where IO0–IO3 serve bidirectional data paths under QPI or Quad SPI mode, enabled by non-volatile QE bit (SR-2 bit 1); standard SPI uses unidirectional DI/DO only. Its 65,536 × 256-byte pages support 1–256 byte writes per page, with erase granularity spanning 4KB sectors (4,096 total), 32KB blocks (256), and 64KB blocks (128).
Hardware write protection combines active-low /WP and /HOLD pins (functional only when QE=0) with volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1), enabling top/bottom array lock, complement protection, and individual sector/block locking via instructions 36h/39h/7Eh/98h - all validated across -40°C to +85°C operation.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z DO, standby current); low = active instruction/data transfer |
| 2 DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in SPI mode; bidirectional I/O in Dual/Quad SPI/QPI when QE=1 |
| 3 /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Active-low hardware lock for status register; repurposed as IO2 when QE=1 |
| 4 GND | Ground Reference | Primary signal and power return path; must be low-impedance for stable read/write margins |
| 5 DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in SPI mode; bidirectional I/O in Dual/Quad SPI/QPI when QE=1 |
| 6 CLK | Serial Clock Input | Edge-triggered timing source: rising edge for input, falling edge for output in all modes |
| 7 /HOLD (IO3) | Hold Input / Quad I/O Line 3 | Pauses ongoing transfer while /CS remains low; repurposed as IO3 when QE=1 |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor required within 10 mm of pin for noise immunity |
Key Features

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 |
|---|---|---|---|
| MX25L12833FZNI-08G | 128Mb density, 133MHz max clock, supports DTR mode; no QPI; different SFDP layout | Lacks QPI and continuous read wrap; requires software-managed command sequencing | Preferred when higher clock rate and DTR compatibility outweigh QPI simplification needs |
| S25FL128SAGMFIR00 | 128Mb density, 108MHz max clock, supports HyperBus interface; includes ECC engine | HyperBus enables 333MB/s burst reads but requires dedicated controller; ECC adds latency for small writes | Chosen for high-throughput imaging buffers where error correction justifies added complexity |
Compared with MX25L12833FZNI-08G and S25FL128SAGMFIR00, the W25Q128FVSJP TR uniquely balances QPI protocol efficiency, 4KB sector flexibility, and industrial temperature support - making it optimal for resource-constrained XIP designs needing both security registers and suspend/resume capability without ECC overhead.

FAQ
What is the package type and lead count for W25Q128FVSJP TR?
W25Q128FVSJP TR uses an 8-pin SOIC 208-mil package (Package Code S), with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC compliance. This matches the pinout shown in Figure 1a of the datasheet, including /CS, CLK, DI, DO, /WP, /HOLD, VCC, and GND - no /RESET pin is present in this variant.
Does W25Q128FVSJP TR support Quad SPI and QPI modes, and how is it enabled?
Yes, W25Q128FVSJP TR supports both Quad SPI and QPI modes. Activation requires setting the Quad Enable (QE) bit in Status Register-2 (bit 1) via instruction 31h. Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively, enabling 4-line bidirectional data transfer - confirmed in Section 4.2 and Table 3.3 of the datasheet.
What erase block sizes does W25Q128FVSJP TR support, and how many sectors are there?
W25Q128FVSJP TR supports uniform 4KB sector erase (4,096 sectors), 32KB block erase (256 blocks), and 64KB block erase (128 blocks), plus full chip erase. The memory array is organized into 65,536 pages of 256 bytes each - verified in Section 1 General Descriptions and Table 2.1 of the datasheet.
How does hardware write protection work on W25Q128FVSJP TR?
W25Q128FVSJP TR implements dual-layer hardware write protection: active-low /WP pin locks status register writes, while BP2–BP0, TB, SEC, and CMP bits in Status Registers 1–3 define protected memory regions. Protection persists across power cycles when configured non-volatilely - detailed in Sections 4.3, 6.2, and 7.1.3–7.1.6 of the datasheet.
Is W25Q128FVSJP TR compatible with JEDEC-standard identification and parameter discovery?
Yes, W25Q128FVSJP TR fully supports JEDEC-standard Manufacturer ID (9Fh), Device ID (two-byte), and SFDP Register (5Ah) for automatic system initialization. It also provides a unique 64-bit serial number (4Bh) - all confirmed in Sections 8.2.29–8.2.30 and 8.2.34 of the datasheet.
