The PCA21125 is a CMOS1 real-time clock (RTC) and calendar ideal for low power applications with operating temperatures up to 125 °C.
The NVT4556 device is used to connect the SIM card to a low-voltage host-side interface.
The PCA8565 is a CMOS1 real-time clock and calendar suitable for low power applications. Programmable clock output, interrupt output, and undervoltage detector are also provided.
The dI2C demonstration board OM13523 is used to demonstrate that a differential I2C bus operates better than a standard I2C bus in a noisy and ground excursion environment.
