NXP provides a range of high-accuracy, low-power real-time clocks (RTCs) for various applications. These RTCs have features that ensure precise timekeeping across diverse environments. such as integrated temperature-compensated crystal oscillators (TCXO) and low-power operation. The AEC-Q100-qualified RTCs are designed for reliability and energy efficiency, with an extended operating temperature range of up to 125°C and automotive-compliant certification.
RTC models that feature integrated TCXO offer enhanced timekeeping accuracy, including the PCA2131, PCF2131, PCF2127, and PCF2129. These models combine a CMOS RTC and calendar with a TCXO and a 32.768 kHz quartz crystal to deliver precise timekeeping with low power consumption. NXP's RTCs with I²C-bus integration provide reliable and efficient timekeeping solutions, featuring automatic battery switching. Other variants, such as the PCF8593 and PCF8564A, are designed for energy efficiency and reliability.
As a global distributor of electronics and industrial components, element14 offers RTCs with I²C or SPI interfaces. RTCs with SPI interfaces offer efficient timekeeping for various applications, with models like the PCF2127 and PCF2129 integrating a TCXO for accuracy. These SPI-based RTCs cater to automotive, industrial, and consumer electronics use cases with low power consumption. Automotive RTCs are purpose designed for precision and reliability in automotive environments. Models such as the PCA2131F, feature a quartz crystal for nano-power operation, while the PCA85073A and PCA8565 are optimized for low power consumption. The same goes for the PCA2129, which incorporates a temperature-compensated crystal oscillator for enhanced accuracy, are notable examples.
