DESCRIPTION
The Xicor X90100 is a non-volatile electronically programmable capacitor. The device is programmed through a simple digital interface. After programming, the chosen setting for the device is retained by internal EEPROM storage whether or not DC power is maintained.

FEATURES
• 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)
• Packages:
    —MSOP (1.1mm x 3.0mm x 3.0mm)
    —FCP (1.35mm x 1.32mm x 0.50mm)

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
