DESCRIPTION
X90100
The Xicor X90100 is a non-volatile electronically pro-
grammable capacitor. The device is programmed
through a simple digital interface. After programming,
the chosen setting for the device is retained by inter-
nal EEPROM storage whether or not DC power is
maintained. There are 32 programmable capacitance
values selectable, ranging from 7.5 pF to 14.5 pF in
0.23 pF increments, in single-ended mode. The dielec-
tric is highly stable, and the capacitance exhibits a very
low voltage coef鏗乧ient. It has virtually no dielectric
absorbtion and has a very low temperature drift coef鏗?
cient in differential mode (<50ppm/擄C).
The X90100 is programmed through three digital inter-
face pins, which have Schmitt triggers and pullup
resistors to secure code retention. The three pins,
INC, U/D, and CS, are identical in operation to other
Xicor chips with up/down interface, such as the x9315
5-bit Digitally Controlled Potentiometer (DCP).
