PCF2129T規(guī)格書詳情
General description
The PCF2129T is a CMOS1 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 very low power consumption. The PCF2129T has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a programmable watchdog function, a timestamp function, and many other features.
Features and benefits
■ Temperature Compensated Crystal Oscillator (TCXO) with integrated capacitors
■ Typical accuracy: ±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
■ 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)
■ Programmable 1 second or 1 minute interrupt
■ Programmable watchdog timer with interrupt
■ Programmable alarm function with interrupt capability
■ Programmable square output
■ Clock operating voltage: 1.8 V to 4.2 V
■ Low supply current: typical 0.70 μA at VDD = 3.3 V
Applications
■ Electronic metering for electricity, water, and gas
■ Precision timekeeping
■ Access to accurate time of the day
■ GPS equipment to reduce time to first fix
■ Applications that require an accurate process timing
■ Products with long automated unattended operation time
