NV Electronically Programmable Capacitor

X90100

FEATURES

DESCRIPTION

• Non-volatile EEPROM storage of programmed

trim codes

• Power On Recall of capacitance setting

• High-Performance Electronically Trimmable

Capacitance

• Excellent Linearity: <0.5 LSB error

• Very Simple Digital Interface

• Fast Adjustments: 5µs max incremental change

• Eliminates the need for mechanical tuning

• Capacitance trimmable from 7.5 pF to 14.5 pF

(single-ended mode)

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 coefﬁcient. It has virtually no dielectric

absorbtion and has a very low temperature drift coefﬁ-

cient in differential mode (<50ppm/°C).

• Packages:

—MSOP (1.1mm x 3.0mm x 3.0mm)

—FCP (1.35mm x 1.32mm x 0.50mm)

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).

APPLICATIONS

• Post-trim of low-cost regenerative receivers

• Tunable RF stages

• Low-cost, Low temperature drift oscillators

• Garage door openers

• Keyless entry

• Industrial wireless control

• Capacitive sensor trimming

• RFID tags
