Product details
Overview
W25Q256JVBIM TR from Winbond is a 256M-bit (32MB) serial NOR flash memory IC supporting standard, dual, and quad SPI interfaces with 4KB uniform sectors, 133MHz clock rate, and 66MB/s continuous read throughput. It operates from 2.7V to 3.6V, consumes <1µA in power-down mode, and is used for code execution-in-place (XIP), firmware storage, and parameter retention in embedded microcontrollers.
For engineers reviewing the W25Q256JVBIM TR datasheet, W25Q256JVBIM TR pinout, W25Q256JVBIM TR application, or W25Q256JVBIM TR equivalent, key selection criteria include 4-byte addressing support, Quad Enable (QE) bit configuration, /HOLD vs /RESET pin availability per package, sector protection granularity, and JEDEC SFDP register compliance for automatic configuration discovery.
Technical Context
The W25Q256JVBIM TR implements a SPI-compatible command set with three address modes (3-byte default, extended register-assisted, and native 4-byte via B7h/E9h), enabling full 256M-bit addressing without external address translation. Its status register architecture includes volatile/non-volatile BP bits, QE bit (SR-2), ADS/ADP bits, and DRV0/DRV1 output strength control - all configurable via standard SPI instructions.
It supports true XIP operation via Fast Read Quad I/O (EBh/ECh), with timing-critical dual/quad I/O functions dependent on QE=1 activation and pin remapping: /WP→IO2 and /HOLD→IO3. The device integrates three 256-byte one-time-programmable (OTP) security registers, 64-bit unique ID, and hardware write-protection using /WP and /RESET pins - the latter available only in SOIC-16 and TFBGA packages.

Pinout & Package
W25Q256JVBIM TR 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 or /RESET depending on configuration. All I/O pins support standard/dual/quad SPI protocols with dynamic role assignment controlled by Status Register-2 Quad Enable (QE) bit.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable; high-impedance DO/IOx when deasserted; required low-to-high transition before new instruction acceptance |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in standard SPI; bidirectional in dual/quad SPI; requires QE=1 for quad mode use as IO1 |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware write-protection for status register when active low; remapped to 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 in dual/quad SPI; required for instruction/address/data loading |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference for all SPI operations; supports Mode 0 and Mode 3 clock polarity/idle states |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transfer when asserted low; remapped to IO3 in quad mode when QE=1; no /RESET function in this package |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply; powers internal logic, charge pump, and I/O buffers; decoupling capacitor required |

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 | Same density (256Mb), 104MHz max clock, no native 4-byte addressing - requires extended address register workaround | Lacks QE bit and SFDP register; requires manual timing setup and address mode management in driver | Prefer W25Q256JVBIM TR when 4-byte addressing, XIP performance, or auto-discovery via SFDP is required |
| S25FL256SAGMFV010 | 256Mb, 133MHz, supports 4-byte addressing and SFDP, but uses different status register layout and security model | Requires Cypress/Infineon-specific driver stack; OTP lock mechanism differs from Winbond's LB bits | Choose W25Q256JVBIM TR for established Winbond ecosystem compatibility, JEDEC-standard SFDP, and unified security register structure |
Compared with MX25L25645GMI-10G and S25FL256SAGMFV010, the W25Q256JVBIM TR offers superior XIP readiness via native 4-byte mode and standardized SFDP, reduces driver development effort, and provides consistent OTP-based security across Winbond's Q-series portfolio.

FAQ
What is the package type and pin count of the W25Q256JVBIM TR?
The W25Q256JVBIM TR uses an 8-pad WSON (8×6 mm) package (Package Code E) with no dedicated /RESET pin. Pin 7 functions as /HOLD in standard/dual SPI mode and as IO3 in quad SPI mode when the Quad Enable (QE) bit is set. This matches the "BIM" suffix per Winbond's ordering nomenclature.
Does the W25Q256JVBIM TR support 4-byte addressing, and how is it enabled?
Yes, the W25Q256JVBIM TR supports native 4-byte addressing via the Enter 4-Byte Address Mode instruction (B7h). Once enabled, all subsequent read/write/erase commands use 32-bit addresses. The setting persists until Exit 4-Byte Address Mode (E9h) is issued or power is cycled - unlike extended address register methods requiring continuous register writes.
How does the Quad Enable (QE) bit affect pin functionality on the W25Q256JVBIM TR?
The QE bit (bit 1 of Status Register-2) must be set to '1' to activate quad SPI mode on the W25Q256JVBIM TR. When QE=1, /WP (Pin 3) becomes IO2 and /HOLD (Pin 7) becomes IO3. If QE=0, those pins retain their hardware protection functions. The QE bit is non-volatile and survives power cycles unless explicitly cleared.
What is the purpose of the /HOLD pin on the W25Q256JVBIM TR, and can it be used as /RESET?
On the W25Q256JVBIM TR, the /HOLD pin (Pin 7) serves only as a hold function - it cannot act as a hardware /RESET because the WSON-8 package lacks the dedicated /RESET pin found in SOIC-16 and TFBGA variants. Hardware reset is unavailable on this part; only software reset (66h + 99h) is supported.
Is the W25Q256JVBIM TR compatible with JEDEC JESD216 SFDP standard?
Yes, the W25Q256JVBIM TR includes a JEDEC JESD216-compliant Serial Flash Discoverable Parameters (SFDP) register accessible via instruction 5Ah. This allows host systems to automatically detect clock frequency limits, erase block sizes, timing parameters, and feature support - eliminating hardcoded driver assumptions and improving portability across flash vendors.
