Product details
Overview
W25Q257JVFIQ TR from Winbond is a 256M-bit (32MB) serial NOR flash memory with Dual/Quad SPI interface, supporting up to 133 MHz clock frequency, 4KB uniform sector erase, and hardware write protection via /WP and /HOLD pins. It operates on a single 2.7–3.6V supply, delivers 66 MB/s continuous read throughput in Quad I/O mode, and is used for code execution (XIP), firmware storage, and parameter retention in embedded microcontrollers.
For engineers reviewing the W25Q257JVFIQ TR datasheet, W25Q257JVFIQ TR pinout, W25Q257JVFIQ TR application, or W25Q257JVFIQ TR equivalent, key selection considerations include 4-byte address mode support, JEDEC SFDP register compliance, 100K program-erase cycles per sector, 20-year data retention, and dual-package availability (WSON 8x6-mm and SOIC-16).
Technical Context
The W25Q257JVFIQ TR implements a flexible SPI command architecture supporting Standard (4-wire), Dual (2 I/O lines), and Quad (4 I/O lines) modes - with Quad operation enabled only when the non-volatile QE bit in Status Register-2 is set. Its memory array is organized into 131,072 pages of 256 bytes each, grouped into 8,192 sectors (4KB) and 512 blocks (64KB), enabling granular erase control.
It supports both 3-byte and 4-byte addressing: ADP bit (non-volatile) sets power-up default mode (factory default = 4-byte), while ADS bit indicates current mode. Hardware reset is available only on SOIC-16 and TFBGA packages; the WSON variant uses /HOLD as IO3 in Quad mode and lacks dedicated /RESET.

Pinout & Package
W25Q257JVFIQ TR is supplied in an 8-pad WSON 8×6-mm package (Package Code E), with no dedicated /RESET pin. Pin functions are shared between standard/Dual and Quad SPI modes: /WP becomes IO2 and /HOLD becomes IO3 when Quad Enable (QE) is active.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO/IO outputs when deasserted |
| DO (IO1) | Serial Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad modes |
| /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when low; becomes IO2 in Quad mode if QE=1 |
| GND | Ground Reference | Primary return path for all I/O and core logic; decoupling required near VCC |
| DI (IO0) | Serial Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad modes |
| CLK | Serial Clock Input | Edge-triggered timing reference for all SPI transfers; supports Mode 0 and Mode 3 |
| /HOLD or /RESET (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transfer when low; becomes IO3 in Quad mode if QE=1; no hardware reset function in WSON |
| VCC | Power Supply | Single 2.7–3.6V supply; requires local 100nF ceramic decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Quad Enable (QE) bit | Non-volatile Status Register-2 bit that reassigns /WP and /HOLD to IO2/IO3, enabling true 4-line data bus |
| Erase/Program Suspend | Allows pausing long erase or program operations to service higher-priority reads without data loss |
| Security Registers | Three 256-byte OTP-lockable registers for secure key or calibration storage, independent of main array |
| SFDP Register | JEDEC JESD216-compliant 64-byte register providing auto-configurable timing and feature parameters |
| Unique 64-bit ID | Factory-programmed, read-only serial number enabling device-level traceability and anti-cloning |
| ADP/ADS bits | Non-volatile ADP sets power-up address mode (default = 4-byte); ADS reflects real-time mode status |

Use Value: Delivers 66 MB/s sustained read throughput, eliminating frame stutter during rapid screen transitions. |
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 |
|---|---|---|---|
| MX25L25735FMI-10G | 256Mb density, 104MHz max clock, SOIC-16 only; lacks 4-byte address mode and SFDP register | Requires software-managed extended addressing; not suitable for systems requiring JEDEC auto-configuration | Select when legacy 3-byte addressing suffices and cost sensitivity outweighs configurability needs. |
| S25FL256SAGMFI000 | 256Mb, 133MHz, Quad SPI, includes HyperBus option; supports 4-byte mode and SFDP but uses different security register layout | Compatible for XIP and OTA use cases, but requires firmware adaptation for security register access commands | Choose for migration paths requiring pin-compatible upgrade with enhanced reliability features (ECC, margin read). |
Compared with MX25L25735FMI-10G, W25Q257JVFIQ TR offers JEDEC SFDP auto-negotiation and native 4-byte addressing; versus S25FL256SAGMFI000, it provides identical performance but simpler security register mapping and broader WSON package availability.

FAQ
Does W25Q257JVFIQ TR support hardware reset, and how is it implemented?
W25Q257JVFIQ TR does not support hardware reset in the WSON 8x6-mm package (FIQ suffix). The /HOLD pin serves as IO3 in Quad mode and cannot function as /RESET. Hardware reset is only available on SOIC-16 and TFBGA variants via a dedicated /RESET pin. For W25Q257JVFIQ TR, system-level reset must be achieved through software commands: Enable Reset (66h) followed by Reset Device (99h), which resets internal state within ~30 µs.
What is the difference between ADP and ADS bits in W25Q257JVFIQ TR?
The ADP (Address Power-up) bit is a non-volatile setting in Status Register-2 that determines the default address mode after power-on: ADP=1 selects 4-byte mode (factory default), ADP=0 selects 3-byte mode. The ADS (Address Status) bit is a volatile flag indicating the *current* active mode - it changes immediately upon executing Enter 4-Byte Mode (B7h) or Exit 4-Byte Mode (E9h) instructions. W25Q257JVFIQ TR uses ADS to inform host firmware of live addressing context without reading ADP.
Can W25Q257JVFIQ TR be used for Execute-in-Place (XIP) applications, and what interface mode is recommended?
Yes, W25Q257JVFIQ TR supports true XIP operation, especially in Quad SPI Fast Read modes (e.g., 6Bh, EBh), delivering up to 66 MB/s continuous throughput. This eliminates need for code shadowing to RAM and reduces system memory footprint. For optimal XIP latency and bandwidth, configure QE=1 to enable Quad I/O, use 4-byte addressing for full 256Mb access, and leverage the SFDP register to auto-configure timing parameters - all validated in W25Q257JVFIQ TR's datasheet Section 6.1.3 and Table 9.6.
How does write protection work on W25Q257JVFIQ TR, and what protection levels are available?
W25Q257JVFIQ TR implements three-tiered write protection: (1) Hardware via /WP pin (active-low, locks status register when asserted), (2) Software via Block Protect (BP0–BP3), Top/Bottom (TB), and Complement (CMP) bits in Status Register-1, and (3) OTP-based via Security Registers with individual lock bits (LB1–LB3). Protection can be applied to sectors as small as 4KB or the entire array. All settings persist across power cycles when written to non-volatile bits - confirmed in Sections 7.1.3–7.1.7 and Figure 10 of the W25Q257JVFIQ TR datasheet.
Is W25Q257JVFIQ TR pin-compatible with earlier W25Q256 variants, and what design adjustments are needed?
W25Q257JVFIQ TR is pin-compatible with W25Q256FV/FJ in the same WSON 8x6-mm package (E-code), sharing identical pinout, voltage, timing, and instruction set. Key design adjustments include enabling 4-byte addressing (via B7h) for full 256Mb access and verifying SFDP parameter parsing, as W25Q257JVFIQ TR extends density beyond legacy 3-byte limits. No PCB or schematic changes are required - confirmed in Winbond's compatibility notes and Section 6.1.4 of the W25Q257JVFIQ TR datasheet.
