W25P40-VSNIG
数据手册.pdf1M-BIT, 2M-BIT AND 4M-BIT SERIAL FLASH MEMORY WITH 40MHz SPI
GENERAL DESCRIPTION
The W25P10 1M-bit, W25P20 2M-bit and W25P40 4M-bit Serial Flash memories provide a storage solution for systems with limited space, pins and power. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1µA for power-down. All devices are offered in space-saving 8-pin SOIC type packagesas shown below. Contact Winbond for availability of alternate packages. As part of a family ofSerial Flash products, Winbond also provides a compatible migration path to8M/16M/32M-bit densities.
