PCF85363A

Tiny Real-Time Clock/calendar with 64 byte RAM, alarm

function, battery switch-over time stamp input, and I2C-bus

Rev. 3.1 — 18 June 2021

Product data sheet

1 General description

The PCF85363A is a CMOS1 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

clock output and two independent interrupt signals, two alarms, I2C 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 999 999 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 μA at VDD = 3.0 V and Tamb = 25 °C

• 400 kHz two-line I2C-bus interface (at VDD = 1.8 V to 5.5 V)

• 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: CL = 6 pF, CL = 7 pF, and

CL = 12.5 pF

3 Applications
