The W25N01GV (1G-bit) Serial SLC NAND Flash Memory provides a storage solution for systems with
limited space, pins and power. The W25N SpiFlash family incorporates the popular SPI interface and the
traditional large NAND non-volatile memory space. They are ideal for code shadowing to RAM, executing
code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single
2.7V to 3.6V power supply with current consumption as low as 25mA active and 10µA for standby. All W25N
SpiFlash family devices are offered in space-saving packages which were impossible to use in the past for
the typical NAND flash memory.
The W25N01GV 1G-bit memory array is organized into 65,536 programmable pages of 2,048-bytes each.
The entire page can be programmed at one time using the data from the 2,048-Byte internal buffer. Pages
can be erased in groups of 64 (128KB block erase). The W25N01GV has 1,024 erasable blocks.
The W25N01GV supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI: Serial Clock,
Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to
104MHz are supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 416MHz
(104MHz x 4) for Quad I/O when using the Fast Read Dual/Quad I/O instructions.
The W25N01GV provides a new Continuous Read Mode that allows for efficient access to the entire
memory array with a single Read command. This feature is ideal for code shadowing applications.
A Hold pin, Write Protect pin and programmable write protection, provide further control flexibility.
Additionally, the device supports JEDEC standard manufacturer and device ID, one 2,048-Byte Unique ID
page, one 2,048-Byte parameter page and ten 2,048-Byte OTP pages. To provide better NAND flash
memory manageability, user configurable internal ECC, bad block management are also available in

Only the Read command structures are different between
the “Continuous Read Mode (BUF=0)” and the “Buffer
Read Mode (BUF=1)”, all other commands are identical.
W25N01GVxxIG: Default BUF=1 after power up
W25N01GVxxIT: Default BUF=0 after power up
LUT stands for Look-Up Table.
OTP pages can only be programmed.
