Product details
Overview
W25Q256JWPIQ TR from Winbond is a 1.8V, 256M-bit (32MB) serial NOR flash memory supporting Dual/Quad SPI interfaces with up to 133MHz clock frequency and 4KB uniform sector architecture. It delivers 532MB/s equivalent Quad I/O throughput, supports 4-byte addressing, and features hardware /RESET, /WP, and /HOLD pins for industrial-grade system control in embedded boot code storage and firmware update applications.
For engineers reviewing the W25Q256JWPIQ TR datasheet, W25Q256JWPIQ TR pinout, W25Q256JWPIQ TR application, or W25Q256JWPIQ TR equivalent, key selection criteria include 1.7–1.95V single-supply operation, JEDEC SFDP register support, 100K program-erase cycles, -40°C to +105°C extended temperature grade, and configurable Quad Enable (QE) bit for IO2/IO3 remapping.
Technical Context
The W25Q256JWPIQ TR implements a flexible SPI command set with standard, dual, and quad I/O modes - requiring QE bit (Status Register-2) to be set for Quad SPI operation, which repurposes /WP as IO2 and /HOLD as IO3. Its block diagram integrates a 256-byte page buffer, column/row decode logic, high-voltage generators, and three 256-byte security registers with OTP locks.
It supports both 3-byte and 4-byte address modes via dedicated instructions (B7h/E9h), with ADP bit determining power-up default mode. Erase granularity includes 4KB sectors (8,192 total), 32KB blocks (2,048), and 64KB blocks (512), enabling fine-grained firmware partitioning and parameter storage without full-chip erase overhead.

Pinout & Package
W25Q256JWPIQ TR uses an 8-pad WSON 6×5-mm package (Package Code P), with exposed pad for thermal dissipation. Pin functions are defined per JEDEC-standard SPI interface with dual/quad I/O capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; places DO/IO pins in high-Z when deasserted to reduce bus contention |
| DI (IO0) | Serial Data Input / Quad I/O 0 | Primary input for standard/dual SPI; becomes bidirectional IO0 in Quad mode when QE=1 |
| DO (IO1) | Serial Data Output / Quad I/O 1 | Primary output for standard/dual SPI; becomes bidirectional IO1 in Quad mode when QE=1 |
| /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for status register; remapped to IO2 in Quad mode when QE=1 |
| GND | Ground Reference | Common return path for all I/O and core logic; requires low-impedance PCB connection |
| VCC | Power Supply | 1.7–1.95V supply for core and I/O; decoupling capacitor required per datasheet layout guidelines |
| /HOLD or /RESET (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing SPI transaction; remapped to IO3 in Quad mode when QE=1; not available on WSON package for reset function |
| CLK | Serial Clock Input | Edge-triggered timing reference for all SPI operations; max 133MHz for Quad I/O |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI Interface | Enables 2× or 4× data rate vs standard SPI; reduces instruction latency and improves boot time in XIP systems |
| 4KB Uniform Sector Architecture | Allows independent erasure of smallest 4KB units - critical for storing calibration data, NV parameters, or OTA update staging areas |
| Erase/Program Suspend & Resume | Permits background read access during long erase/program cycles - maintains system responsiveness in real-time applications |
| JEDEC SFDP Register | Provides standardized, software-readable memory topology and timing parameters - eliminates hardcoded driver assumptions |
| Three 256-byte Security Registers | OTP-lockable storage for keys, certificates, or device-specific secrets - prevents unauthorized firmware cloning or tampering |

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 | 3V supply (2.7–3.6V); no /RESET pin in 8-pin SOIC; 104MHz max Quad SPI clock | Lacks hardware reset and extended temperature grade; lower throughput limits XIP performance | Select only if system uses 3V domain and does not require -40°C to +105°C operation or hardware reset signaling |
| S25FL256SAGMFI000 | 1.8V supply; 133MHz Quad SPI; includes HyperBus interface option; no /HOLD pin in 8-pin WSON | Supports dual-interface (SPI/HyperBus); higher pin count variants offer dedicated /RESET but WSON variant omits it | Prefer when HyperBus compatibility or enhanced error correction (ECC) is required; verify /HOLD functionality is unused in target design |
Compared with MX25L25645GMI-10G and S25FL256SAGMFI000, the W25Q256JWPIQ TR uniquely combines 1.8V operation, integrated /RESET in SOIC/TFBGA variants, 4-byte addressing by default, and full 4KB sector protection - making it optimal for space-constrained industrial controllers needing robust firmware resilience.

FAQ
What is the supply voltage range for the W25Q256JWPIQ TR?
The W25Q256JWPIQ TR operates from 1.7V to 1.95V. This narrow 1.8V nominal range ensures compatibility with modern low-power microcontrollers and eliminates the need for level-shifting circuitry in 1.8V system designs. The W25Q256JWPIQ TR maintains full specification compliance across this range, including timing, endurance, and data retention metrics.
Does the W25Q256JWPIQ TR support Quad SPI mode out of the box?
No - Quad SPI mode requires the Quad Enable (QE) bit in Status Register-2 to be set first. Until configured, the W25Q256JWPIQ TR defaults to Standard SPI operation. Setting QE remaps /WP to IO2 and /HOLD to IO3; this configuration is volatile unless written to non-volatile bits, and must be verified after power-up in production firmware.
What package type does the W25Q256JWPIQ TR use?
The W25Q256JWPIQ TR uses an 8-pad WSON 6×5-mm package (Package Code P) with exposed thermal pad. This compact, lead-free RoHS-compliant package supports reflow soldering and provides thermal performance suitable for industrial ambient conditions up to +105°C.
Can the W25Q256JWPIQ TR be used for Execute-in-Place (XIP) applications?
Yes - the W25Q256JWPIQ TR supports XIP via Dual/Quad SPI Fast Read instructions (e.g., 6Bh/6Ch), delivering up to 532MB/s effective bandwidth. Its 4KB uniform sector architecture and erase-suspend capability allow seamless code execution while background updates occur, making it suitable for real-time embedded systems requiring zero-copy firmware execution.
How many program-erase cycles does the W25Q256JWPIQ TR guarantee?
The W25Q256JWPIQ TR guarantees a minimum of 100,000 program-erase cycles per sector. This endurance rating applies to all 8,192 sectors and is validated across the full -40°C to +105°C operating range, ensuring reliable field firmware updates throughout the product lifecycle without premature wear-out.
