Product details
Overview
W25Q256JVFJQ TR from Winbond is a 256M-bit (32MB) serial NOR flash memory IC supporting standard, dual, and quad SPI interfaces with 133 MHz clock rate, 4KB uniform sector architecture, and industrial-grade -40°C to +85°C operation. It delivers 66 MB/s continuous read throughput in Quad I/O mode and supports execute-in-place (XIP) for code storage in microcontroller boot applications.
For engineers reviewing the W25Q256JVFJQ TR datasheet, W25Q256JVFJQ TR pinout, W25Q256JVFJQ TR application, or W25Q256JVFJQ TR equivalent, this device is selected for embedded firmware storage, secure parameter retention, and high-speed code shadowing where space-constrained PCBs require SPI-compatible nonvolatile memory with JEDEC ID, SFDP, and 64-bit unique serial number support.
Technical Context
The W25Q256JVFJQ TR implements a 131,072-page (256-byte/page) memory array with flexible erase granularity: 4KB sectors, 32KB blocks, 64KB blocks, and full-chip erase. It uses volatile/non-volatile status registers (SR1–SR3) to control write protection, quad enable (QE), address mode (ADP/ADS), and output driver strength (DRV1/DRV0).
It supports both 3-byte and 4-byte addressing modes - the latter enabled via B7h instruction and stored in non-volatile ADP bit - and includes hardware /RESET on SOIC/TFBGA packages, while /HOLD shares pin functionality with IO3 in quad mode when QE=1.

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 |
|---|---|---|---|
| MX25L25645GMI-10G | 256Mb, 104 MHz max clock, no /RESET pin in 8-pin SOIC/WSON; lacks SFDP v1.6 and 64-bit UID | Suitable for cost-sensitive consumer designs where extended address mode and unique ID are not required | Select when legacy SPI compatibility and lower unit cost outweigh advanced configuration features |
| S25FL256SAGMFV001 | 256Mb, 80 MHz max clock, supports HyperBus interface; includes ECC and configurable dummy cycles | Better suited for high-reliability applications needing built-in error correction and deterministic latency | Prefer when system-level ECC or deterministic read timing is mandatory, despite lower bandwidth than W25Q256JVFJQ TR |
Compared with MX25L25645GMI-10G and S25FL256SAGMFV001, the W25Q256JVFJQ TR provides highest SPI bandwidth (133 MHz), integrated SFDP v1.6 for automatic configuration discovery, and 64-bit UID for secure provisioning - making it optimal for modern embedded systems requiring speed, configurability, and traceability.

FAQ
What is the maximum SPI clock frequency supported by the W25Q256JVFJQ TR?
The W25Q256JVFJQ TR supports up to 133 MHz for standard, dual, and quad SPI operations. At this frequency, quad I/O achieves an effective data rate of 532 MHz (133 MHz × 4), enabling 66 MB/s continuous read throughput using Fast Read Quad I/O (EBh) instructions. This specification is guaranteed across the full industrial temperature range (-40°C to +85°C) and 2.7–3.6 V supply.
Does the W25Q256JVFJQ TR include a hardware reset pin?
No, the W25Q256JVFJQ TR does not include a dedicated /RESET pin. The /RESET function is only available on SOIC-16 and TFBGA packages (e.g., W25Q256JVSFQ or W25Q256JVBYIQ). The W25Q256JVFJQ TR uses an 8-pin WSON package (Code E) with no /RESET pin; reset must be performed via software command sequence (66h + 99h) or power cycle.
How is 4-byte addressing enabled and retained on the W25Q256JVFJQ TR?
4-byte addressing is enabled by issuing the Enter 4-Byte Address Mode instruction (B7h). The ADP bit in Status Register-2 controls whether this mode persists across power cycles: when ADP = 1, the device powers up in 4-byte mode; when ADP = 0, it defaults to 3-byte mode. The ADP bit is non-volatile and writable via Write Status Register-2 (31h) instruction.
What package type is used for the W25Q256JVFJQ TR?
The W25Q256JVFJQ TR uses an 8-pin WSON (Very Thin Small Outline No-Lead) package measuring 8 mm × 6 mm with an exposed thermal pad (Package Code E). This surface-mount package supports reflow soldering, provides low inductance I/O paths, and is optimized for high-density PCB layouts in industrial and automotive applications.
Can the W25Q256JVFJQ TR be used for execute-in-place (XIP) applications?
Yes, the W25Q256JVFJQ TR supports true execute-in-place (XIP) operation via its Quad SPI interface. When configured with QE = 1 and using Fast Read Quad I/O (EBh), it delivers low-latency random access to code stored in flash - enabling ARM Cortex-M and RISC-V microcontrollers to execute firmware directly from the W25Q256JVFJQ TR without copying to RAM first.
