Product details
Overview
W25Q257FVFIQ TR from Winbond is a 256M-bit (32MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104 MHz clock frequency with 50 MB/s continuous read throughput. It features uniform 4KB sectors (8,192 total), 64KB blocks (512 total), and supports execute-in-place (XIP) operation for code storage in embedded microcontrollers and SoCs.
For engineers reviewing the W25Q257FVFIQ TR datasheet, W25Q257FVFIQ TR pinout, W25Q257FVFIQ TR application, or W25Q257FVFIQ TR equivalent, key selection considerations include 4-byte addressing support, Quad Enable (QE) bit configuration, /HOLD or /RESET pin multiplexing in WSON-8, and JEDEC SFDP register compatibility for automated configuration.
Technical Context
The W25Q257FVFIQ TR implements a flexible SPI command architecture with three address modes (3-byte default, software-enabled 4-byte, and power-up configurable ADP bit), enabling seamless migration from legacy 16MB designs to 32MB capacity without bus width changes. Its dual-mode /HOLD or /RESET pin (controlled by HOLD/RST bit in Status Register-3) allows functional reconfiguration without hardware modification in WSON-8 packages.
It integrates volatile and non-volatile status register bits including Quad Enable (QE), Block Protect (BP0–BP3), Top/Bottom protect (TB), Complement protect (CMP), and Output Driver Strength (DRV0/DRV1), permitting fine-grained hardware write protection down to individual 4KB sectors and OTP-locked security registers (3 × 256 bytes).

Pinout & Package
W25Q257FVFIQ TR is packaged in an 8-pad WSON 8×6 mm (Package Code E), RoHS-compliant, moisture-sensitive level 3 device. Pin 1 is /CS; pins 2–3–5–7 are bidirectional I/Os (IO1, IO2, IO0, IO3); pin 4 is GND; pin 6 is CLK; pin 8 is VCC. The /WP and /HOLD functions are active-low and disabled when Quad Enable (QE) is set.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high = device deselected, DO in high-Z; must transition high→low before new instruction accepted |
| DO / IO1 (Pin 2) | Serial Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI; used for read data and status |
| /WP / IO2 (Pin 3) | Write Protect Input / Quad I/O 2 | Hardware write lock for status register; repurposed as IO2 when QE=1 - disables /WP function |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB connection |
| DI / IO0 (Pin 5) | Serial Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI; carries instructions, addresses, and write data |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI operations; supports Mode 0 and Mode 3 clock polarity/idle states |
| /HOLD or /RESET / IO3 (Pin 7) | Hold or Reset Input / Quad I/O 3 | Multiplexed function: /HOLD pauses ongoing transfers; /RESET forces internal reset - controlled by HOLD/RST bit in SR3; disabled when QE=1 |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply; requires local 100 nF ceramic decoupling capacitor placed near pin |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read with Wrap | Supports 8/16/32/64-byte wrap bursts - reduces instruction overhead to ≤8 clocks per 24-bit address, enabling true XIP execution |
| Quad Peripheral Interface (QPI) | 2-clock instruction cycle mode - eliminates opcode byte overhead, increasing effective bandwidth over standard SPI |
| JEDEC SFDP Register | Standardized 64-byte parameter table - enables automatic driver configuration without hard-coded timing or command tables |
| 64-bit Unique ID | Factory-programmed read-only serial number - supports secure boot, device authentication, and field inventory tracking |
| Security Registers | Three 256-byte OTP-lockable regions - stores cryptographic keys, calibration data, or license tokens with hardware-enforced write protection |
| Erase/Program Suspend & Resume | Allows background interrupt handling during long erase cycles - critical for real-time OS environments requiring deterministic latency |

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 |
|---|---|---|---|
| Winbond W25Q256JWEIQ | Same 256M-bit density, but uses newer 1.8 V / 3.3 V dual-voltage design; includes octal word read (E3h) and enhanced SFDP v1.6 | Requires voltage translation in pure 3.3 V systems; supports faster burst reads but lacks /RESET pin in WSON-8 | Select for new designs targeting lower power and future-proof SFDP-based initialization |
| Macronix MX25L25645G | 256M-bit, 3.3 V only; supports Dual/Quad SPI but no QPI mode; max clock 80 MHz; no 4-byte address ADP bit | Lacks QPI and configurable 4-byte addressing - limits scalability beyond 16 MB without software address remapping | Select when QPI complexity is unnecessary and cost sensitivity outweighs bandwidth needs |
Compared with W25Q257FVFIQ TR, W25Q256JWEIQ offers higher efficiency and modern SFDP compliance but requires voltage-aware design, while MX25L25645G provides simpler implementation at lower bandwidth and fixed 3-byte addressing - making W25Q257FVFIQ TR optimal for balanced performance, legacy compatibility, and industrial temperature robustness.

FAQ
What is the difference between W25Q257FVFIQ TR and W25Q256FVIQ?
The W25Q257FVFIQ TR is the correct, fully specified part number per Winbond's official ordering matrix; "W25Q256FVIQ" is not a valid Winbond part. The "257" designation reflects the actual 268,435,456-bit (32MB) capacity, consistent with JEDEC naming conventions for 256M-bit flash devices. W25Q257FVFIQ TR uses the FV silicon revision and FIQ package marking, confirming its qualification for industrial temperature and tape-and-reel delivery.
Does W25Q257FVFIQ TR support 4-byte addressing by default?
No, W25Q257FVFIQ TR defaults to 3-byte addressing after power-up. The 4-byte mode must be explicitly enabled using the Enter 4-Byte Address Mode instruction (B7h). However, the ADP bit in Status Register-3 can be programmed non-volatilely to auto-enable 4-byte mode on subsequent power-ups - a key feature distinguishing it from earlier W25Q256 variants.
Can the /HOLD and /RESET functions coexist on the W25Q257FVFIQ TR WSON-8 package?
No - on the W25Q257FVFIQ TR in WSON-8 (Package Code E), pin 7 serves as either /HOLD or /RESET depending on the HOLD/RST bit setting in Status Register-3, but never both simultaneously. When QE=1 (Quad SPI enabled), this pin becomes IO3 and neither /HOLD nor /RESET is available. For independent /RESET functionality, the SOIC-16 variant (Package Code F) must be used.
What does the "TR" suffix mean in W25Q257FVFIQ TR?
The "TR" suffix in W25Q257FVFIQ TR indicates tape-and-reel packaging per EIA-481 standard, with 2,000 units per reel. It denotes the standard shipping format for surface-mount assembly and confirms the part meets Winbond's industrial-grade moisture sensitivity level (MSL) 3 handling requirements - distinct from tray ("Q") or tube ("T") packaging options.
Is Quad Enable (QE) bit volatile or non-volatile in W25Q257FVFIQ TR?
In W25Q257FVFIQ TR, the Quad Enable (QE) bit (bit 1 of Status Register-2) is non-volatile and retains its state across power cycles. It is programmed using Write Status Register-2 (31h) with appropriate write enable sequence. Once set, QE remains active until explicitly cleared - ensuring persistent Quad SPI operation without reconfiguration at boot.
