The X25138 is a CMOS 128K-bit serial E2PROM, internally organized as 16K x 8. The X25138 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) inp.
DESCRIPTION The X25138 is a CMOS 128K-bit serial E2PROM, internally organized as 16K x 8. The X25138 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. The X25138 also features two additional inputs that provide the end user with added flexibility. By asserting the HOLD input, the X25138 will ignore transitions on its inp.
