PT7C4363BQ Automotive Real-time Clock Features Description
• Drop-In Replacement for PT7C4363 The PT7C4363BQ serial real-time clock is an automotive low- • Supports High-ESR Crystals Up To 100kΩ power clock/calendar with a programmable square-wave • Supports alarm and timer output. • Supports I2C-Bus's high speed mode (400 kHz) • 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, • Low backup current: typ. 400nA at VDD=3.0V and minutes, hours, day, date, month, and year information. TA=25°C The date at the end of the month is automatical y adjusted for • Operating range: 1.3V to 5.5V months with fewer than 31 days, including corrections for leap • Extended Operating Temp: -40°C to 125°C year. The clock operates in the 24-hour format indicator. • AECQ-100 Compliant for Automotive Application • Totally Lead-Free & Ful y RoHS Compliant (Notes 1 & 2) Table 1 shows the basic functions of PT7C4363BQ. More • Halogen and Antimony Free. “Green” Device (Note 3) details are shown in section: overview of functions. • PPAP Capable (Note 4) • Packaging (Pb-free & Green): 8-Pins, SOIC (W)
