X25128中文资料SPI Serial E²PROM with Block Lock™ Protection数据手册ICmic规格书

描述 Description

DESCRIPTION
The X25128 is a CMOS 131,072-bit serial E2PROM, internally organized as 16K x 8. The X25128 features a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple three-wire bus. The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input, allowing any number of devices to share the same bus.FEATURES
