PCA2131

Nano-power highly accurate RTC with integrated quartz

crystal for automotive applications

Rev. 1.0 — 26 July 2021

Product data sheet

1 General description

The PCA2131 is a CMOS Real Time Clock (RTC) and calendar with an integrated

Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz

crystal optimized for very high accuracy and ultra low power consumption. The

PCA2131 has a selectable I²C-bus or SPI-bus, a backup battery switch-over circuit, a

programmable watchdog function, four timestamps function, and many other features.

For a selection of NXP Real-Time Clocks, see Section 15.1.

2 Features and benefits

• AEC-Q100 compliant version: PCA2131TF/Q900 for automotive applications

• Operating temperature range from -40 °C to +105 °C

• Temperature Compensated Crystal Oscillator (TCXO) with trimmed integrated

capacitors

• Clock operational up to 125 °C

• Ultra low supply current: typical 106 nA at V_DD= 3.3 V

• Temperature compensated RTC, typical accuracy ±3 ppm from -40 °C to +85 °C;

±8 ppm from +85 °C to +105 °C

• Integration of a 32.768 kHz quartz crystal and oscillator in the same package

• Provides year, month, day, weekday, hours, minutes, seconds and 1/100 seconds

• Provides leap year correction

• Timestamp function

– with interrupt capability

– detection of four different events on four input pins (for example, for tamper detection)

• 2-line bidirectional 400 kHz Fast-mode I²C-bus interface

• 4-line SPI-bus with separate data input and output (maximum speed 6.5 Mbit/s)

• Battery backup input pin and switch-over circuitry

• Battery backed output voltage

• Battery low detection function

• Power-On Reset (POR)

• Power-On Reset Override (PORO) function

• Software reset function

• Two interrupt outputs (open-drain)

• Programmable 1 second or 1 minute interrupt

• Programmable watchdog timer with interrupt

• Programmable alarm function with interrupt capability

• Programmable square output

• Clock operating voltage: 1.2 V to 5.5 V
