HT1382 I2C/3-Wire Real Time Clock Feature Applications • Real Time Clock/Calendar Functions –– Includes: Sec, Minutes, Hours, Day, Date, Month, and year in BCD format • Utility meters • Clock operating voltage: 2.0V~5.5V • Wireless equipment • Consumer electronics • Portable equipment • Supply voltage VDD=2.7V~5.5V • POS equipment • Automatic leap year correction, valid until year 2099 • Computer products • Other industrial/Medical/Automotive applications • Automatic supply switch over • Integrated oscillator load capacitors – CL=12.5pF General Description • Clock compensation The HT1382 is a low power real time clock device with two serial interface: I2C or 3-wire. The interface mode is selected by the chosen chip version. The device provides both clock and calendar information in BCD format and also includes alarm functions. The calendar is accurate until the year 2099 and includes automatic leap year correction. • Programmable alarm and interrupt function • 15 selectable frequency outputs • 4 Bytes EEPROM for user • Serial commutation via I2C or 3-wire interface • 8-pin SOP package for I2C interface • 10-pin MSOP package for 3-wire interface Rev. 1.70 An external 32768Hz crystal is used as the device oscillator for device timing for which is provided an integrated crystal load capacitance of 12.5pF. The device includes a crystal oscillator temperature compensation function and internal power control circuitry detects power failures and automatically switches to the battery supply when a power failure occurs. 1 August 01, 2019 PDF
