PCA2131TF/Q900Y

PCA2131 Nano-Power CMOS Real Time Clock (RTC)

NXP Semiconductors PCA2131 Nano-Power CMOS Real Time Clock (RTC) is an RTC and calendar with an on-chip Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768kHz quartz crystal integrated into the same package. The AEC-Q100-compliant PCA2131 is optimized for very high accuracy and ultra-low power consumption. Address and data are transferred by a selectable 400kHz fast-mode I²C Bus or a 4-line SPI Bus (6.5Mbit/s maximum speed) with separate data input and output.
