Winbond W25X40CLUXIG TR NOR Flash Memory

The W25X40CLUXIG Serial Flash memories provides a storage solution for systems with limited space, pins and power. The 25X series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.3V to 3.6V power supply with current consumption as low as 1mA active and 1μA for power-down. All devices are offered in space-saving packages.

The W25X40CLUXIG arrays are organized into 2048 programmable pages of 256-bytes each. Up to 256bytes can be programmed at a time.

The W25X40CLUXIG have 128 erasable sectors, 16 erasable 32KB blocks and 8 erasable 64KB blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. Single and Dual Serial Peripheral Interface.

The W25X40CLU support the standard Serial Peripheral Interface (SPI), and a high performance dual output as well as Dual I/O SPI: Serial Clock, Chip Select, Serial Data DI (I/O0), DO (I/O1). SPI clock frequencies up to 104MHz are supported allowing equivalent clock rates of 208MHz when using the Fast Read Dual Output instruction. These transfer rates are comparable to those of 8 and 16-bit Parallel Flash memories. The Continuous Read Mode allows for efficient memory access with as few
as 16-clocks of instruction-overhead to read a 24-bit address, allowing true XIP (execute in place) operation.
