Real Time Clock/Calendar with EEPROMDESCRIPTION\nThe X1226 device is a Real Time Clock with clock/calendar, two polled alarms with integrated 512x8 EEPROM, oscillator compensation, and battery backup switch. The oscillator uses an external, low-cost 32.768kHz crystal. All compensation and trim components are integrated on the chip. This eliminates several external discrete components and a trim capacitor, saving board area and component cost.FEATURES\n• Real Time Clock/Calendar\n   —Tracks time in Hours, Minutes, and Seconds\n   —Day of the Week, Day, Month, and Year\n• 2 Polled Alarms (Non-volatile)\n   —Settable on the Second, Minute, Hour, Day of the Week, Day, or Month\n   —Repeat Mode (periodic interrupts)\n• Oscillator Compensation On Chip\n   —Internal feedback resistor and compensation capacitors\n   —64 position Digitally Controlled Trim Capacitor\n   —6 digital frequency adjustment settings to ±30ppm\n• Battery Switch or Super Cap Input\n• 512 x 8 Bits of EEPROM\n   —64-Byte Page Write Mode\n   —8 modes of Block Lock™ Protection\n   —Single Byte Write Capability\n• High Reliability\n   —Data Retention: 100 years\n   —Endurance: 100,000 cycles per byte\n• 2-Wire™ Interface Interoperable With I2C\n   —400kHz data transfer rate\n• Frequency Output (SW Selectable: Off, 1Hz, 4096Hz or 32.768kHz)\n• Low Power CMOS\n   —1.25µA Operating Current (Typical)\n• Small Package Options\n   —8 Ld SOIC and 8 Ld TSSOP\n• Repetitive Alarms\n• Temperature Compensation\n• Pb-Free Plus Anneal Available (RoHS Compliant)APPLICATIONS\n• Utility Meters\n• HVAC Equipment\n• Audio / Video Components\n• Set Top Box / Television\n• Modems\n• Network Routers, Hubs, Switches, Bridges\n• Cellular Infrastructure Equipment\n• Fixed Broadband Wireless Equipment\n• Pagers / PDA\n• POS Equipment\n• Test Meters / Fixtures\n• Office Automation (Copiers, Fax)\n• Home Appliances\n• Computer Products\n• Other Industrial / Medical / Automotive
