Product details
Overview
W25Q256JVBIM from Winbond is a 256M-bit (32MB) serial NOR flash memory with Dual/Quad SPI interface, organized into 131,072 × 256-byte pages and supporting 4KB/32KB/64KB erase granularity. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock rate (532MHz equivalent Quad I/O), and features hardware /WP and /HOLD pins plus dedicated /RESET in select packages - used for code storage, XIP execution, and firmware update in embedded microcontrollers.
For engineers reviewing the W25Q256JVBIM datasheet, W25Q256JVBIM pinout, W25Q256JVBIM application, or W25Q256JVBIM equivalent, key selection criteria include 4-byte addressing support, Quad Enable (QE) bit configuration, JEDEC SFDP register compliance, 100K program-erase cycles per sector, and package-specific /RESET availability in TFBGA/SOIC variants.
Technical Context
The W25Q256JVBIM implements a standard SPI bus with Mode 0 and Mode 3 compatibility, supports 3-byte and 4-byte address modes via ADP bit and Extended Address Register, and requires non-volatile QE bit setting in Status Register-2 to enable Quad I/O operation. Its architecture enables true execute-in-place (XIP) with Fast Read Quad I/O (EBh/ECh) achieving up to 66MB/s continuous transfer.
It integrates volatile/non-volatile status register bits for block protection (BP0–BP3, TB, CMP), security registers (3×256-byte OTP-locked), 64-bit unique ID, and hardware write-protection via active-low /WP and /HOLD pins - with /HOLD repurposed as IO3 in Quad mode and /RESET available only on SOIC-16 and TFBGA packages.

Pinout & Package
W25Q256JVBIM uses the 8-pad WSON 8×6-mm package (Package Code E), with no dedicated /RESET pin - /HOLD (Pin 7) serves dual function as hold input or reset input only in Standard/Dual SPI mode; Quad SPI repurposes it as IO3. All signals are SPI-compliant and support 3-/4-byte addressing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high = device deselected (high-Z DO, standby current); low = active communication |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional I/O1 in Dual/Quad SPI after QE=1 |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register; becomes IO2 in Quad mode when QE=1 |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance connection |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional I/O0 in Dual/Quad SPI after QE=1 |
| 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 SPI transaction when low; becomes IO3 in Quad mode (QE=1); no /RESET function in WSON |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI XIP Support | Enables direct code execution from flash via Fast Read Quad I/O (EBh/ECh), eliminating RAM copy overhead |

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 | 256Mb, 104MHz max clock, no dedicated /HOLD pin in 8-pin SOIC; supports only 3-byte addressing by default | Lacks 4-byte addressing and Quad I/O suspend/resume; lower bandwidth limits XIP performance | Choose for cost-sensitive designs where 4-byte addressing and suspend/resume are not required |
| S25FL256SAGMFIR10 | 256Mb, 133MHz, includes built-in ECC and sector lockdown; supports both /RESET and /HOLD in same package | Higher reliability features suit safety-critical systems but increase BOM cost and footprint | Prefer when system-level functional safety (IEC 61508) or field-programmable sector lockdown is mandated |

FAQ
What package type does W25Q256JVBIM use, and does it include a hardware /RESET pin?
W25Q256JVBIM uses the 8-pad WSON 8×6-mm package (Package Code E). It does not include a dedicated hardware /RESET pin - the /HOLD pin (Pin 7) functions as hold input only and cannot serve as /RESET in this variant. Dedicated /RESET is available only on SOIC-16 and TFBGA packages of the W25Q256JV family.
Does W25Q256JVBIM support 4-byte addressing, and how is it enabled?
Yes, W25Q256JVBIM fully supports 4-byte addressing to access its full 256M-bit capacity. It is enabled via the Enter 4-Byte Address Mode instruction (B7h), and the Power-Up Address Mode (ADP) bit in Status Register-1 determines whether 4-byte mode persists after reset. The ADP bit is non-volatile and writable.
How many program-erase cycles does W25Q256JVBIM guarantee per sector, and what is its data retention?
W25Q256JVBIM guarantees a minimum of 100,000 program-erase cycles per sector and provides greater than 20 years of data retention at +25°C ambient temperature. These values are specified under industrial-grade operating conditions (–40°C to +85°C) and apply uniformly across all 4KB sectors.
What is the role of the Quad Enable (QE) bit in W25Q256JVBIM, and where is it located?
The Quad Enable (QE) bit is a non-volatile bit located in Status Register-2 (SR2) of the W25Q256JVBIM. When QE=1, the /WP and /HOLD pins are remapped to IO2 and IO3 respectively, enabling full Quad SPI operation. QE must be set before issuing Quad I/O instructions such as EBh (Fast Read Quad I/O).
Can W25Q256JVBIM be used for execute-in-place (XIP) applications, and what interface mode is recommended?
Yes, W25Q256JVBIM supports true execute-in-place (XIP) operation using Fast Read Quad I/O instructions (EBh/ECh). Quad SPI mode is recommended for XIP due to its 532MHz equivalent bandwidth and low-latency random access - delivering up to 66MB/s continuous read throughput while minimizing CPU wait states.
