Description
The Digilent Pmod RTCC is a compact and versatile Real-Time Clock/Calendar module designed to easily add precise timekeeping capabilities to your embedded systems and IoT projects. This module features a built-in lithium coin cell backup, ensuring that your system keeps track of time even when the main power is disconnected. With its integrated EEPROM and SRAM, it provides not only time-tracking but also non-volatile and volatile storage space for configuration settings or critical data logging.
Engineered for rapid prototyping, the Pmod RTCC communicates via the industry-standard I²C interface and adheres to the Digilent Pmod Interface Specification, ensuring seamless compatibility with a wide range of development boards. Whether you are building a data logger, a time-triggered controller, or a connected home device, the Pmod RTCC provides a reliable, plug-and-play solution.
Key Features
- Reliable Timekeeping: Integrated real-time clock/calendar with lithium coin cell backup for continuous operation.
- Flexible Storage: Includes 128 bytes of non-volatile EEPROM and 64 bytes of SRAM for your data.
- Advanced Functionality: Features two independent alarms and a multi-function pin capable of generating a configurable square wave.
