Product details
Overview
W25N01JWZEIT 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 up to 166MHz STR and 80MHz DTR, delivers 80MB/s continuous read throughput, and integrates on-chip 1-bit ECC and Bad Block Management for embedded storage applications requiring high reliability in space-constrained designs.
For engineers reviewing the W25N01JWZEIT datasheet, W25N01JWZEIT pinout, W25N01JWZEIT application, or W25N01JWZEIT equivalent, key selection considerations include its 8-pad WSON 8×6-mm (ZE) package, BUF-mode default behavior (BUF=1 at power-up), DTR timing compliance, internal ECC configuration register control, and support for both Continuous Read and Buffer Read operational modes.
Technical Context
The W25N01JWZEIT implements a standard SPI-compatible interface extended to Dual/Quad I/O and DTR protocols, enabling address/data transfers on both clock edges. Its architecture includes a 2,048-byte page buffer, configurable BUF mode (via Status Register-2 bit 5), and dedicated registers for ECC enable (SR2[4]), Quad Enable (SR2[6]), and DLP activation (SR4[1]).
It uses a 128KB uniform block erase granularity and supports JEDEC-standard device ID (9Fh), Unique ID access, and ten 2KB OTP pages. Write protection is implemented via /WP pin, software lock bits (BP0–BP3, SRP0/SRP1), and OTP-lockable protection registers - all operating within 1.70–1.95V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Type | SLC NAND Flash - single-level cell architecture ensures higher endurance (100k cycles) and data retention (10 years) vs. MLC/TLC. |
| Capacity | 1G-bit / 128M-byte - organized as 65,536 pages × 2,048 bytes, supporting efficient firmware/image storage in resource-limited systems. |
| Interface Speed | 166MHz STR / 80MHz DTR - enables 664MB/s theoretical quad-I/O bandwidth and 80MB/s sustained continuous read transfer rate. |
| Supply Voltage | 1.70V–1.95V - low-voltage operation reduces system power consumption and simplifies PMIC design for battery-powered devices. |
| ECC Support | On-chip 1-bit ECC - corrects single-bit errors per 528-byte sector; status bits (ECC-1/ECC-0 in SR3) report correction events without host intervention. |
| Operating Temp | −40°C to +85°C - qualified for industrial temperature range, suitable for automotive infotainment, industrial HMIs, and networking equipment. |
| Endurance | 100,000 program/erase cycles - validated with on-chip ECC enabled, ensuring long-term reliability in frequent update scenarios like OTA firmware storage. |
Pinout & Package
W25N01JWZEIT is housed in an 8-pad WSON 8×6-mm package (JEDEC MO-252 compliant, package code ZE), with exposed thermal pad (non-electrical). Pin assignments follow standard SPI+I/O layout optimized for minimal PCB footprint and signal integrity in high-speed dual/quad configurations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select | Active-low enable for SPI command/address/data transactions; must be deasserted between commands to avoid bus contention. |
| CLK | Serial Clock | Master-generated clock driving all SPI/Dual/Quad/DTR operations; supports up to 166MHz STR or 80MHz DTR frequency. |
| IO0 | Serial Data I/O (DI/DO) | Primary bidirectional data line for standard SPI; functions as DI in write, DO in read, and IO0 in Dual/Quad modes. |
| IO1 | Serial Data I/O (DO) | Secondary bidirectional line; serves as DO in standard SPI, and IO1 in Dual/Quad; supports DTR edge-triggered sampling. |
| IO2 | Write Protect Input (/WP) | Hardware write-protection input; when low, disables write/erase instructions unless SRP0/SRP1 are cleared and WP-E is disabled. |
| IO3 | Hold Input (/HOLD) | Pauses ongoing serial communication without deselecting device; allows host to service interrupts while preserving transaction state. |
| /RESET | Hardware Reset | Asynchronous active-low reset that clears internal state, resets status registers, and returns device to power-on default configuration. |
| VSS | Ground | Reference ground for all I/O and core logic; requires low-impedance connection to minimize noise coupling in high-speed reads. |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode (BUF=0) | Enables linear sequential access across full memory array with single Read instruction - eliminates need for repeated Page Data Read commands in boot code shadowing. |
| DTR Command Support | Transfers addresses and read data on both rising and falling clock edges at up to 80MHz, doubling effective throughput versus STR-only modes. |
| Configurable ECC Engine | 1-bit error correction per 528-byte sector is enabled/disabled via SR2[4]; status reported in SR3[1:0] for real-time host monitoring of bit-flip events. |
| Bad Block Management (BBM) | Hardware-accelerated BBM with LUT access (A5h) and automatic invalid block replacement - reduces host driver complexity and improves field reliability. |
| OTP Memory Space | Ten 2KB one-time-programmable pages store calibration data, security keys, or device-specific parameters - immune to accidental overwrite after programming. |

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, SOIC-16 package only; supports STR up to 133MHz but no DTR mode or Continuous Read Mode. | Lacks DTR timing and BUF-mode flexibility; requires host-side ECC implementation instead of integrated engine. | Select when legacy SOIC layout compatibility is required and DTR/Continuous Read features are not needed. |
| Micron MT29F1G08ABAEAWP-AIT | 1G-bit SLC NAND, 3.3V supply, TSOP-48 package; supports ONFI 2.3 interface, not SPI; requires external controller and ECC management. | Requires dedicated NAND controller and complex driver stack; incompatible with SPI-based microcontrollers. | Choose only for systems already designed around parallel NAND architecture with dedicated controller hardware. |
Compared with MX35LF1GE4AB and MT29F1G08ABAEAWP-AIT, the W25N01JWZEIT offers SPI-native integration, DTR-enabled bandwidth scaling, on-chip ECC, and dual read modes - reducing host processing load and PCB area while supporting industrial temperature and low-voltage operation.

FAQ
What is the default read mode for W25N01JWZEIT at power-up?
The W25N01JWZEIT powers up in Buffer Read Mode (BUF=1) as indicated by its part number suffix 'G'. This means the device expects Page Data Read (13h) commands before each data fetch. To use Continuous Read Mode (BUF=0), the host must write SR2[5]=0 via Write Status Register (1Fh) instruction after initialization.
Does W25N01JWZEIT require external ECC hardware?
No. The W25N01JWZEIT includes an on-chip 1-bit ECC engine that automatically corrects single-bit errors per 528-byte sector. ECC status is reported in Status Register-3 (SR3[1:0]), and the engine is enabled by setting SR2[4]=1. No external ECC circuitry is needed for basic error correction.
How does the /WP pin function on W25N01JWZEIT?
The /WP pin on W25N01JWZEIT provides hardware-level write protection. When held low, it disables all write, erase, and status register modification instructions - unless overridden by volatile or OTP-configured protection bits (WP-E, BPx, SRP0/SRP1) in the protection register. It operates independently of software locks.
What package type does W25N01JWZEIT use?
W25N01JWZEIT uses an 8-pad WSON 8×6-mm package (JEDEC MO-252), identified by package code 'ZE'. It features a thermally enhanced exposed pad (non-electrical) and is optimized for high-density PCB layouts with minimal trace length requirements for 166MHz SPI signaling.
Can W25N01JWZEIT be used in automotive applications?
Yes. The W25N01JWZEIT is rated for −40°C to +85°C operation and supports 10-year data retention and 100,000 program/erase cycles - meeting key requirements for automotive infotainment and telematics modules. Its 1.8V supply and SPI interface simplify integration with automotive-grade MCUs.
