Add real-time clock and calendar functionality to the design using the RTC PROTO Board. This accessory board employs a PCF8583 real-time clock and calendar chip that allows user to keep record of the current time even when the microcontroller is turned off. It features an alarm function and can be used to generate an interrupt as well. The real-time clock is driven by a coin-cell battery which is included.
This board allows easy and quick access to the real time and date along with corrections for leap year. RTC PROTO Board allows easy connection to standard prototyping boards using five pin pads that have a standard 0.1

Product Description
Product Description
The RTC PROTO Board enables you to use a real-time-clock and calendar in your applications. It features an PCF8583 that keeps track of the current time even when the microcontroller is turned off. The real-time clock is driven by a special battery that is not connected to the normal power supply. It is easily connected to standard prototyping boards.
IC/Module: PCF8583 Clock and Calendar with 240 x 8-bit RAM
The PCF8583 is a real-time clock and calendar IC designed to keep track of the current time and date even when the microcontroller is turned off. Based on a 2048-bit static RAM, it is capable of generating interrupts as well as provide timer and alarm functions. As each data byte is written or read, the built-in word address register is automatically incremented. The chip comprises of a 256 by 8 bit RAM with an 8 bit auto-increment address register, an on-chip 32.768 kHz oscillator circuit, a frequency divider, a serial two-line bidirectional I2C-bus interface, and a Power-On Reset (POR) circuit.
