Product details
Overview
W25Q256JVBJQ from Winbond is a 256M-bit (32MB) serial NOR flash memory supporting Standard, Dual, and Quad SPI interfaces with 4KB uniform sectors, 133MHz clock rate, and industrial temperature range (–40°C to +85°C). It enables execute-in-place (XIP) code execution, data/parameter storage, and firmware updates in space-constrained embedded systems.
For engineers reviewing the W25Q256JVBJQ datasheet, W25Q256JVBJQ pinout, W25Q256JVBJQ application, or W25Q256JVBJQ equivalent, this page delivers verified package mapping (WSON 8x6-mm), confirmed Quad SPI timing (532MHz equivalent), JEDEC ID support, SFDP register compliance, and hardware /RESET availability per package variant.
Technical Context
The W25Q256JVBJQ implements a flexible SPI interface with configurable address modes (3- or 4-byte), non-volatile Quad Enable (QE) bit in Status Register-2 required for Quad I/O operation, and dual-mode /HOLD or /RESET functionality on Pin 7 (WSON/WFLGA) or dedicated /RESET pin (SOIC/TFBGA). Its architecture supports simultaneous erase/program suspend-resume and individual sector lock via security registers.
It integrates three 256-byte OTP-lockable security registers, 64-bit unique serial number, and SFDP (Serial Flash Discoverable Parameters) register for automatic configuration discovery. The device uses volatile/non-volatile status register bits (BP0–BP3, TB, CMP, SRP, DRV0/DRV1) to enable granular write protection and output driver strength control without external components.

Pinout & Package
W25Q256JVBJQ is packaged in an 8-pad WSON 8×6-mm (Package Code E), with exposed thermal pad. Pin 1 is /CS; Pin 2 is DO (IO1); Pin 3 is /WP (IO2); Pin 4 is GND; Pin 5 is DI (IO0); Pin 6 is CLK; Pin 7 is /HOLD or /RESET (IO3); Pin 8 is VCC. /HOLD function is disabled when Quad SPI is active (QE=1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high = high-Z outputs and standby current (<1 µA); low = active SPI communication |
| DO / IO1 (Pin 2) | Serial Data Output / Bidirectional I/O | Outputs data in Standard SPI; serves as IO1 in Dual/Quad modes; requires QE=1 for Quad use |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register; becomes IO2 only when QE=1; active-low protection |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable timing |
| DI / IO0 (Pin 5) | Serial Data Input / Bidirectional I/O | Accepts instructions/addresses in Standard SPI; serves as IO0 in Dual/Quad modes |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing source: rising edge for input, falling edge for output in all SPI modes |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing read/write when low; becomes IO3 only when QE=1; not available in Quad mode unless reconfigured |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required within 5 mm of pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with XIP support | Enables direct code execution from flash via Fast Read Quad I/O (EBh/ECh), eliminating RAM copy overhead |
| 4KB uniform sector architecture | Allows precise firmware partitioning: bootloader, app, config, and calibration data each in isolated, independently erasable sectors |
| JEDEC ID + SFDP register | Permits automatic driver initialization and runtime parameter discovery without hardcoded timing or configuration tables |
| Three 256-byte security registers | Store cryptographic keys or calibration data with OTP locking (LB1–LB3), preventing unauthorized readback or overwrite |
| Erase/Program suspend-resume | Interrupts long erase/program operations to service time-critical interrupts, then resumes from exact byte offset |
| Hardware /WP + software BP bits | Combines physical pin-level protection with configurable block locks (BP0–BP3, TB, CMP) for multi-layer firmware integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L25645GMI-10G | Same density (256Mb), 104MHz max clock, no dedicated /RESET pin in SOIC; lacks SFDP register and 64-bit UID | Lower throughput limits XIP performance; no auto-discovery capability increases driver development effort | Choose for cost-sensitive designs where Quad SPI speed and SFDP are non-critical |
| S25FL256SAGMFV010 | 256Mb, 80MHz clock, supports HyperBus interface; includes ECC and configurable latency modes | Higher pin count (16-pin SOIC), larger footprint; ECC adds reliability but increases complexity for simple storage | Prefer when system requires built-in error correction or migration path to HyperBus-based controllers |
Compared with MX25L25645GMI-10G and S25FL256SAGMFV010, W25Q256JVBJQ delivers higher bandwidth (133MHz vs. ≤104MHz), standardized SFDP discovery, and integrated security features - making it optimal for XIP-capable, firmware-updatable industrial and automotive platforms requiring minimal driver customization.

FAQ
What is the package type and pin count of W25Q256JVBJQ?
W25Q256JVBJQ uses an 8-pad WSON 8×6-mm package (Package Code E) with exposed thermal pad. It has eight terminals: /CS, DO (IO1), /WP (IO2), GND, DI (IO0), CLK, /HOLD or /RESET (IO3), and VCC. This compact footprint supports high-density PCB layouts while maintaining thermal performance in industrial environments.
Does W25Q256JVBJQ support hardware reset, and how is it implemented?
W25Q256JVBJQ does not include a dedicated /RESET pin in the WSON 8×6-mm package (E). Pin 7 functions as /HOLD in Standard/Dual SPI mode and as IO3 in Quad SPI mode. Hardware reset is only available on SOIC-16 (Package Code F) and TFBGA (Package Codes B/C) variants. For W25Q256JVBJQ, system-level reset must be handled via software commands (66h + 99h) or power-cycle sequencing.
How is Quad SPI mode enabled on W25Q256JVBJQ?
Quad SPI mode on W25Q256JVBJQ is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) using instruction 31h. Once QE=1, pins /WP (Pin 3) and /HOLD (Pin 7) become IO2 and IO3 respectively. The device then accepts Quad I/O instructions like EBh (Fast Read Quad I/O) and 34h (Quad Input Page Program). QE is non-volatile and persists across power cycles.
What security features does W25Q256JVBJQ provide beyond basic write protection?
W25Q256JVBJQ provides layered security: hardware /WP pin protection, non-volatile block protect bits (BP0–BP3), top/bottom/complement array locking, individual sector lock/unlock (36h/39h), global lock (7Eh), and three 256-byte OTP-locked security registers (LB1–LB3). It also includes a factory-programmed 64-bit unique ID and SFDP register for authenticated configuration discovery - all accessible via standard SPI commands.
Can W25Q256JVBJQ operate in both 3-byte and 4-byte address modes, and how is switching managed?
Yes, W25Q256JVBJQ supports both 3-byte and 4-byte address modes. Switching is controlled by instructions: B7h enters 4-byte mode; E9h exits it. The Power-Up Address Mode (ADP) bit in Status Register-3 determines default mode after reset. In 3-byte mode, Extended Address Register (C8h/C5h) extends addressing beyond 16MB. All standard, dual, and quad read/program instructions have 4-byte variants (e.g., 13h, 3Ch, 6Ch, 12h, 34h).
