X1226S8I Product details

DESCRIPTION

The 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

• Real Time Clock/Calendar

   —Tracks time in Hours, Minutes, and Seconds

   —Day of the Week, Day, Month, and Year

• 2 Polled Alarms (Non-volatile)

   —Settable on the Second, Minute, Hour, Day of the Week, Day, or Month

   —Repeat Mode (periodic interrupts)

• Oscillator Compensation on chip

   —Internal feedback resistor and compensation capacitors

   —64 position Digitally Controlled Trim Capacitor

   —6 digital frequency adjustment settings to ±30ppm

• Battery Switch or Super Cap Input

• 512 x 8 Bits of EEPROM

   —64-Byte Page Write Mode

   —8 modes of Block Lock™ Protection

   —Single Byte Write Capability

• High Reliability

   —Data Retention: 100 years

   —Endurance: 100,000 cycles per byte

• 2-Wire™ Interface interoperable with I2C*

   —400kHz data transfer rate

• Frequency Output (SW Selectable: Off, 1Hz,

4096Hz or 32.768kHz)

• Low Power CMOS

   —1.25µA Operating Current (Typical)

• Small Package Options

   —8-Lead SOIC and 8-Lead TSSOP
