X9312 Summary of contents
Page 1
... The Xicor X9312 is a solid state nonvolatile potentiom- eter and is ideal for digitally controlled resistance trim- ming. The X9312 is a resistor array composed of 99 resistive elements. Between each element and at either end are tap points accessible to the wiper element. The position of the wiper element is controlled by the CS, U/D, and INC inputs ...

... The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete the X9312 will be placed in the low power standby mode until the device is selected once again. ...

... The adjustments might be based on user preference, system parameter changes due to temperature drift, etc... The state of U/D may be changed while CS remains LOW. This allows the host system to enable the X9312 and then move the wiper up and down until the proper trim is attained ...
