X25128P-2.7中文资料XICOR数据手册PDF规格书

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.
