... A Chip Select pin allows several devices to share a common serial interface. Communication back to the host controller is via a single serial data line thanks to the CAT522 Tri- Stated Data Output pin. A RDY/BSY in concert with an internal low voltage detector signals proper operation of the non-volatile NVRAM memory Erase/Write cycle. The CAT522 is available in the 0° ...

... For all CLOCK The CAT522’s clock controls both data flow in and out of the IC and non-volatile memory cell programming. Serial data is shifted into the DI pin and out of the DO pin on the clock’s rising edge. While it is not neces– ...

... DATA OUTPUT Data is output serially by the CAT522, LSB first, via the Data Out (DO) pin following the reception of a start bit and two address bits by the Data Input (DI). DO becomes active whenever CS goes high and resumes its high impedance Tri-State mode when CS returns low ...

... When it is desired to save a new setting acquired using this feature, the new value must be reloaded into the programming. This is because the CAT522’s internal control circuitry discards from the programming register the new data two clock cycles after receiving PROG signal is received. ...
