Product details
Overview
W25N01JWSFIG from Winbond is a 1.8V serial SLC NAND flash memory IC with 1G-bit (128MB) capacity, organized as 65,536 × 2,048-byte pages and 1,024 × 128KB erasable blocks. It supports Dual/Quad SPI interfaces up to 166MHz STR and 80MHz DTR, delivers 80MB/s continuous read throughput, and features on-chip 1-bit ECC, Bad Block Management, and configurable Buffer/Continuous Read modes. It is used in embedded boot storage, firmware code shadowing, and space-constrained industrial controllers.
For engineers reviewing the W25N01JWSFIG datasheet, W25N01JWSFIG pinout, W25N01JWSFIG application, or W25N01JWSFIG equivalent, key selection criteria include its 1.7–1.95V supply range, dual-mode read architecture (BUF=1 default), 100,000 program/erase cycles, -40°C to +85°C operation, and support for DTR Fast Read Quad I/O instructions with 4-byte addressing.
Technical Context
The W25N01JWSFIG implements a true NAND flash architecture with page-based programming (2,048B/page), uniform 128KB block erase, and integrated Bad Block Management via a Look-Up Table (LUT). Its command set includes standard SPI, Dual/Quad I/O, and DTR variants - all sharing identical instruction opcodes but differing in data transfer timing and edge usage.
It uses volatile and OTP-configurable status registers (SR-1 to SR-4) to control ECC enable (ECC-E), buffer mode (BUF), quad enable (QE), DLP (Data Learning Pattern), and output driver strength (ODS). The device supports both hardware (/WP, /HOLD) and software write protection, with SRP bits enabling OTP lock of protection settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Type | SLC NAND Flash - single-level cell architecture enabling 100K P/E cycles and deterministic latency vs. TLC/QLC. |
| Capacity | 1 G-bit (128 MB) - organized as 65,536 pages × 2,048 bytes, supporting efficient firmware image storage. |
| Interface Speed | 166 MHz STR / 80 MHz DTR - enables 664 MB/s theoretical Quad I/O bandwidth and 80 MB/s sustained continuous read. |
| Read Mode | Buffer Read (default at power-up) and Continuous Read - eliminates need for repeated Page Data Read commands during linear access. |
| ECC | On-chip 1-bit ECC per 528-byte sector - corrects single-bit errors and reports cumulative status via ECC-1/ECC-0 bits. |
| Endurance & Retention | 100,000 program/erase cycles and 10-year data retention - validated under JEDEC JESD22-A117 conditions. |
| Operating Voltage | 1.70 V to 1.95 V - compatible with low-voltage SoC I/O domains and reduces system power budget. |
| Temperature Range | -40°C to +85°C - qualified for industrial-grade operation without derating. |
Pinout & Package
W25N01JWSFIG is packaged in an 8-pad WSON 8×6-mm (package code ZE), with exposed thermal pad. Pin functions are fully SPI-compatible and support Dual/Quad I/O operation using shared IO pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select | Active-low enable for SPI command/data transactions; must be deasserted between commands. |
| CLK | Serial Clock | Master-generated clock driving all STR/DTR transfers; supports up to 166 MHz frequency. |
| IO0 | Serial Data I/O (DI/DO) | Primary bidirectional data line for standard SPI; also serves as DI in Dual/Quad modes. |
| IO1 | Serial Data I/O (DO) | Second bidirectional line used for DO in Dual SPI and I/O1 in Quad SPI; doubles data rate vs. standard SPI. |
| IO2 | Serial Data I/O (/WP) | Third bidirectional line; functions as /WP when not in Quad mode; enables hardware write protection. |
| IO3 | Serial Data I/O (/HOLD) | Fourth bidirectional line; functions as /HOLD when not in Quad mode; suspends ongoing reads without CS deassertion. |
| /RESET | Hardware Reset | Asynchronous active-low reset that clears internal state and reinitializes register defaults. |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode (BUF=0) | Enables direct sequential access across full memory array with one Read command - eliminates inter-page command overhead for code shadowing. |
| DTR Fast Read Quad I/O | Transfers address and data on both clock edges at up to 80 MHz - achieves higher effective bandwidth than STR while maintaining signal integrity. |
| Configurable ECC Enable (ECC-E) | Volatile bit controlling on-chip 1-bit error correction per 528-byte sector - improves reliability without external ECC logic. |
| Bad Block Management (BBM) | Hardware-accelerated LUT-based replacement mapping - transparently redirects accesses from factory-invalid or worn-out blocks. |
| OTP Protection Registers | One-time programmable lock bits (SRP0/SRP1, OTP-L) secure write protection, configuration, and status register settings against accidental overwrite. |
| Data Learning Pattern (DLP) | Dynamic pattern adaptation during DTR reads - enhances timing margin and signal integrity in high-speed, noise-sensitive layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NAND flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Macronix MX35LF1GE4AB | 1G-bit SLC NAND, 1.8V, 133MHz STR, no DTR support, 64KB block size, no on-chip ECC. | Lacks DTR and integrated ECC; requires external ECC engine and different block management firmware. | Select when DTR is unnecessary and external ECC logic already exists in design. |
| Micron MT29F1G01ABAFDWB | 1G-bit SLC NAND, 3.3V supply, 104MHz STR, 128KB blocks, supports ONFI 2.3 but not SPI. | Parallel interface only; incompatible pinout and protocol; requires dedicated NAND controller. | Choose only for legacy systems with existing ONFI NAND infrastructure and 3.3V I/O rails. |
Compared with MX35LF1GE4AB and MT29F1G01ABAFDWB, W25N01JWSFIG uniquely combines SPI compatibility, DTR timing, on-chip ECC, and 1.8V operation - reducing BOM count, layout complexity, and firmware development effort for new embedded designs.

FAQ
What is the default read mode for W25N01JWSFIG at power-up?
W25N01JWSFIG powers up in Buffer Read mode (BUF=1) by default, as indicated by the "G" suffix in its part number. This mode requires explicit Page Data Read commands before each data access. To use Continuous Read mode, the BUF bit in Status Register-2 must be cleared via Write Status Register instruction (1Fh).
Does W25N01JWSFIG support 4-byte addressing, and how is it enabled?
Yes, W25N01JWSFIG supports 4-byte addressing for full 1G-bit access and is enabled automatically when issuing instructions with "with 4-Byte Address" in their name (e.g., 0Ch, 3Ch, 6Ch). No separate address-width configuration is required - the device detects and processes 32-bit addresses natively in all supported read and program commands.
How does the on-chip ECC in W25N01JWSFIG operate, and where are status flags reported?
W25N01JWSFIG performs 1-bit error correction per 528-byte sector using on-chip logic. ECC status is reported in Status Register-3 (Cxh) via ECC-1 and ECC-0 bits, indicating no error, single-bit correction, or uncorrectable multi-bit failure. ECC-E bit in Status Register-2 must be set to enable correction during read operations.
Can W25N01JWSFIG's /WP and /HOLD pins be used as general-purpose I/Os?
No - /WP and /HOLD are dedicated function pins with fixed roles defined in the datasheet. In standard SPI mode, IO2 functions as /WP and IO3 as /HOLD; in Quad SPI mode, both serve as bidirectional data lines (IO2/IO3). Their behavior is controlled by instruction context and QE bit, not user-configurable as GPIOs.
What package type does W25N01JWSFIG use, and what is its package code?
W25N01JWSFIG uses the 8-pad WSON 8×6-mm package with exposed thermal pad, identified by package code ZE. This compact, surface-mount package supports automated assembly and provides thermal performance suitable for industrial ambient temperatures up to +85°C.
