W25N01GVZEIG ORIGINAL

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
W25N01GV.
