• 4 Non-volatile data registers for each
   potentiometer
• Non-volatile storage of multiple wiper positions
• Standby current < 5µA max
• VCC: 2.7V to 5.5V Operation
• 50KΩ, 100KΩ versions of total resistance
• 100 yr. data retention
• Single supply version of X9250
• Endurance: 100,000 data changes per bit per
   register
• 24-lead SOIC, 24-lead TSSOP, 24-lead CSP
   (Chip Scale Package)
• Low power CMOS
