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 to104MHz 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.

DUAL/QUAD SPI For Industrial & Industrial Plus Grade The W25Q256JV supports standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to read data or status from the device on the falling edge of CLK.
