PT7C4563BQ Automotive Grade Real-time Clock Features Description
• Drop-in Replacement for PT7C4563 The PT7C4563BQ serial real-time clock is an automotive- • Supports High-ESR Crystals up to 100kΩ grade low-power clock/calendar with a programmable square- • Uses External 32.768kHz Quartz Crystal wave output. It supports up to 125°C operating temperature. • Supports I2C Bus' High-Speed Mode (400kHz) • Includes Time (Hour/Minute/Second) and Calendar Address and data are transferred serially via a 2-wire (Year/Month/Date/Day) Counter Functions (BCD Code) bidirectional bus. The clock/calendar provides seconds, • Programmable Square Wave Output Signal minutes, hours, day, date, month, and year information. • Oscillator Stop Flag • Low Backup Current: Typ. 400nA at VDD=3.0V and The date at the end of the month is automatical y adjusted for TA=25°C months with fewer than 31 days—including corrections for • Operating Range: 1.3V to 5.5V leap year. The clock operates in the 24-hour format indicator. • Extended Operating Temp: -40°C to 125°C • AECQ-100 Compliant for Automotive Application Table 1 shows the basic functions of PT7C4563BQ. More • Totally Lead-Free & Ful y RoHS Compliant (Notes 1 & 2) details are shown in the Overview of Functions section. • Halogen and Antimony Free. “Green” Device (Note 3)
• PPAP Capable (Note 4)
• Packaging (Pb-free & Green): 8-Pins, SOIC (W)
