PCA8565 Real time clock/calendar Rev. 4 5 December 2014 Product data sheet 1. General description 1 The PCA8565 is a CMOS real time clock and calendar optimized for low power consumption. A programmable clock output, interrupt output and voltage-low detector are also provided. All address and data are transferred serially via a two-line bidirectional 2 I C-bus. Maximum bus speed is 400 kbit/s. The built-in word address register is incremented automatically after each written or read data byte. For a selection of NXP Real-Time Clocks, see Table 36 on page 40 2. Features and benefits AEC-Q100 compliant (PCA8565TS) for automotive applications Provides year, month, day, weekday, hours, minutes and seconds based on a 32.768 kHz quartz crystal Clock operating voltage: 0.9 V to 5.5 V at room temperature Extended operating temperature range: 40 C to +125 C Low current typical 0.65 Aat V = 3.0 V and T =25 C DD amb 2 400 kHz two-wire I C-bus interface (at V = 1.8 V to 5.5 V) DD Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz and 1Hz) Alarm and timer functions Internal power-on reset 2 I C-bus slave address: read A3h and write A2h Open-drain interrupt pin One integrated oscillator capacitor 3.
