PCF85363A Tiny Real-Time Clock/calendar with 64 byte RAM, alarm 2 function, battery switch-over time stamp input, and I C-bus Rev. 3.2 22 September 2021 Product data sheet 1 General description 1 The PCF85363A is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss. The RTC can also be configured as a stop-watch (elapsed time counter). Three time log registers triggered from battery switch-over as well as input driven events. Featuring 2 clock output and two independent interrupt signals, two alarms, I C interface and quartz crystal calibration, 64 byte battery backed-up RAM. For a selection of NXP Real-Time Clocks, see Table 71. 2 Features and benefits UL Recognized Component (PCF85363ATL) Provides year, month, day, weekday, hours, minutes, seconds and 100th seconds based on a 32.768 kHz quartz crystal Stop-watch mode for elapsed time counting. From 100th seconds to 999999 hours Two independent alarms Battery back-up circuit WatchDog timer Three timestamp registers Two independent interrupt generators plus predefined interrupts at every second, minute, or hour 64 byte battery backed-up RAM Frequency adjustment via programmable offset register Clock operating voltage: 0.9 V to 5.5 V Low current typical 0.28 A at V = 3.0 V and T = 25 C DD amb 2 400 kHz two-line I C-bus interface (at V = 1.8 V to 5.5 V) DD Programmable clock output for peripheral devices (32.768 kHz, 16.384 kHz, 8.192 kHz, 4.096 kHz, 2.048 kHz, 1.024 kHz, and 1 Hz) Configurable oscillator circuit for a wide variety of quartzes: C = 6 pF, C = 7 pF, and L L C = 12.5 pF L 3 Applications Elapsed time counter Network powered devices Printers and copiers Battery backed up systems Digital voice recorders 1 The definition of the abbreviations and acronyms used in this data sheet can be found in Section 23.NXP Semiconductors PCF85363A Tiny Real-Time Clock/calendar with 64 byte RAM, alarm function, battery switch-over time stamp input, 2 and I C-bus Data loggers Mobile equipment White goods Digital cameras Accurate high duration timer 4 Ordering information Table 1.Ordering information Topside Package Type number marking Name Description Version PCF85363ATL/A 363A DFN2626-10 plastic thermal enhanced extremely thin small outline SOT1197-1 package no leads 10 terminals body 2.6 x 2.6 x 0.5 mm with 0.5 mm pitch.
