Product details
Overview
W25N01GVZEIT from Winbond is a 1G-bit (128MB) Serial SLC NAND Flash memory with Dual/Quad SPI interface, organized as 65,536 × 2,048-byte pages and 1,024 × 128KB erasable blocks. It supports 104MHz SPI clocking, delivers up to 50MB/s continuous read throughput in Continuous Read Mode, and operates from 2.7V–3.6V across –40°C to +85°C. It is used for code shadowing, XIP execution, and embedded firmware/data storage in space-constrained industrial and IoT devices.
For engineers reviewing the W25N01GVZEIT datasheet, W25N01GVZEIT pinout, W25N01GVZEIT application, or W25N01GVZEIT equivalent, key selection considerations include its default Buffer Read Mode (BUF=1), on-chip 1-bit ECC, hardware/software write protection via /WP and SRP bits, and support for Fast Read Quad I/O (6Bh/6Ch) and 4-byte addressing.
Technical Context
The W25N01GVZEIT implements a true SLC NAND architecture with internal page buffer management, enabling full-page program operations and 128KB uniform block erase. Its command set includes dedicated instructions for Bad Block Management (A1h), BBM Look-Up Table access (A5h), and Last ECC Failure Page Address retrieval (A9h).
It features three volatile/OTP-configurable status registers: SR-1 (protection & WP-E control), SR-2 (ECC-E, BUF mode, OTP-L), and SR-3 (ECC-1/0, P-FAIL/E-FAIL, BUSY). The device supports both Standard SPI (DI/DO) and multiplexed Dual/Quad I/O modes using IO0–IO3, with /WP and /HOLD repurposed as IO2/IO3 in Quad mode when WP-E=0.

Pinout & Package
W25N01GVZEIT uses the 8-pad WSON 8×6-mm package (JEDEC MO-252, package code ZE), optimized for high-density PCB layouts with exposed thermal pad. Pin 4 is GND and Pin 8 is VCC; all I/O pins are 3.3V-tolerant with internal pull-downs on /CS, /WP, and /HOLD.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (/CS) | Chip Select Input | Active-low enable; must transition high→low after power-up before accepting commands |
| 2 (DO / IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI; high-Z when /CS high |
| 3 (/WP / IO2) | Write Protect Input / I/O2 | Hardware lock for SR-1 when WP-E=1; functions as IO2 in Quad mode when WP-E=0 |
| 4 (GND) | Ground Reference | Primary signal and power return; connects to thermal pad for thermal dissipation |
| 5 (DI / IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI; used for all command/address loading |
| 6 (CLK) | Serial Clock Input | Edge-triggered master clock; rising edge for input, falling edge for output in all SPI modes |
| 7 (/HOLD / IO3) | Hold Input / I/O3 | Pauses ongoing read/write while /CS low; functions as IO3 in Quad mode when WP-E=0 |
| 8 (VCC) | Power Supply | 2.7–3.6 V core supply; requires local 1 µF ceramic decoupling adjacent to pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NAND flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Macronix MX35LF1GE4AB | Same 1G-bit SLC NAND density, 104MHz max clock, but lacks Continuous Read Mode and uses different BBM register mapping (0x90h vs A5h) | Requires host-side BBM table parsing; no native 50MB/s continuous streaming mode | Prefer W25N01GVZEIT when Continuous Read Mode or standardized A5h BBM access is required |
| Micron MT29F1G08ABA | Parallel NAND interface (not SPI); requires NAND controller; higher pin count and PCB footprint | Not pin-compatible or protocol-compatible; mandates external ECC engine and complex driver stack | Choose W25N01GVZEIT for SPI-native designs avoiding NAND controller complexity and layout overhead |
Compared with MX35LF1GE4AB, W25N01GVZEIT provides faster sequential access via Continuous Read Mode and standardized BBM access, while versus MT29F1G08ABA it eliminates NAND controller dependency and reduces design cycle time by 6+ weeks.

FAQ
What is the default read mode for W25N01GVZEIT at power-up?
W25N01GVZEIT powers up in Buffer Read Mode (BUF=1), meaning the Read Data (03h) instruction loads data into the internal 2,048-byte buffer before serial output. To use Continuous Read Mode (BUF=0), the Configuration Register (SR-2) must be written with BUF=0 using instruction 1Fh. This setting persists only until next power cycle unless locked in OTP.
Does W25N01GVZEIT support Quad SPI commands with 4-byte addressing?
Yes, W25N01GVZEIT supports Fast Read Quad I/O with 4-byte addressing (instruction ECh) and Quad Load Program Data with 4-byte addressing (34h). These commands are valid in both BUF=0 and BUF=1 modes and require the 4-byte address mode to be enabled via the Extended Address Register (EAR) using instruction C8h before execution.
How does hardware write protection work on W25N01GVZEIT?
Hardware write protection on W25N01GVZEIT is activated when the WP-E bit in Status Register-1 is set to 1. In this state, tying /WP to GND disables all program, erase, and status register write operations-including OTP programming-and renders the entire device read-only. Quad SPI read commands are also disabled, enforcing strict hardware-level lockdown.
What is the purpose of the BBM Look-Up Table (LUT) in W25N01GVZEIT?
The BBM Look-Up Table (LUT) in W25N01GVZEIT is a dedicated on-die table storing physical addresses of factory-marked and field-detected invalid blocks. It is accessed via instruction A5h and enables host firmware to skip defective blocks during logical-to-physical address translation, simplifying wear leveling and improving system-level reliability without external block management logic.
Can W25N01GVZEIT be used for Execute-in-Place (XIP) applications?
Yes, W25N01GVZEIT supports XIP via Fast Read Dual/Quad I/O instructions (3Bh/6Bh and variants), delivering up to 416 MHz equivalent bandwidth. Its Continuous Read Mode further enhances XIP performance by removing page-boundary delays, making it suitable for direct code execution in microcontrollers with SPI memory-mapped interfaces.
