... SDA STOP LOGIC SLAVE ADDRESS REGISTER (6) SCL +COMPARATOR ( ( ( © Xicor, 1991 Patents Pending 3848-1 X24022 2 Serial E PROM DESCRIPTION The X24022 is a CMOS 2048 bit serial E nally organized 256 x 8. The X24022 features a serial interface and software protocol allowing operation on a simple two wire bus. Three address inputs allow up to eight devices to share a common two wire bus ...
