PCA8565BS/1,118 NXP

PCA8565 Real time clock/calendar Rev. 02 16 June 2009 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. AEC-Q100 compliant (PCA8565TS) for automotive applications. 2. Features n Provides year, month, day, weekday, hours, minutes and seconds based on a 32.768 kHz quartz crystal n Century ag n Clock operating voltage: 1.8 V to 5.5 V n Extended operating temperature range: - 40 C to +125 C n Low backup current; typical 0.65 A at V = 3.0 V and T =25 C DD amb 2 n 400 kHz two-wire I C-bus interface (at V = 1.8 V to 5.5 V) DD n Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz and 1 Hz) n Alarm and timer functions n Internal power-on reset 2 n I C-bus slave address: read A3h and write A2h n Open-drain interrupt pin n One integrated oscillator capacitor 3.
