PCF2127

Accurate RTC with integrated quartz crystal for industrial

applications

Rev. 8 — 19 December 2014

Product data sheet

1. General description

The PCF2127 is a CMOS¹Real 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 very low power consumption. The PCF2127

has 512 bytes of general-purpose static RAM, a selectable I²C-bus or SPI-bus, a backup

battery switch-over circuit, a programmable watchdog function, a timestamp function, and

many other features.

For a selection of NXP Real-Time Clocks, see Table 94 on page 89

2. Features and benefits

 UL Recognized Component

 Operating temperature range from 40 C to +85 C

 Temperature Compensated Crystal Oscillator (TCXO) with integrated capacitors

 Typical accuracy:

 PCF2127AT: 3 ppm from 15 C to +60 C

 PCF2127T: 3 ppm from 30 C to +80 C

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

 Provides year, month, day, weekday, hours, minutes, seconds, and leap year

correction

 512 bytes of general-purpose static RAM

 Timestamp function

 with interrupt capability

 detection of two different events on one multilevel input pin (for example, for tamper

detection)

 Two line bidirectional 400 kHz Fast-mode I²C-bus interface

 3 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

 Extra power fail detection function with input and output pins

 Power-On Reset Override (PORO)

 Oscillator stop detection function

 Interrupt output (open-drain)
