DS1302-RTC-CHIP

DS1302 is a tickle-charge timekeeping chip which contains a real-time clock/calendar and 31 bytes of static RAM. DS1302 uses serial communication to interact with microcontrollers. Also, it automatically adjust the date for the month with fewer days. Clock operates in 24hr or 12hr format with an AM/PM indicator. DS1302 chip is also commonly used as DS1302 RTC module which comes with a 32 kHz crystal and on-board battery backup all in a small SIP module that is compatible with a breadboard. DS1302 module are used by makers with Arduino, Raspberry Pi and other Micro-controllers.

DS1302-RTC-CHIP is a real-time clock capable of counting seconds, minutes, hours, date, month, day of the week and year up to 2100. The leap year compensation is made to incorporate internally. The static RAM DS1302 is of 31 Bytes. A simple serial SPI interface makes DS1302 communicate and interact with any microprocessor or microcontroller having an SPI communication interface. There are two forms of time indication i.e. 24 hours format or 12 hours with an indication of AM/PM. It operates on very low power. Retention of data and clock information can only take 1W at most. Synchronous serial communication is used for connecting this RTC chip with a microprocessor. RST (reset), I/O (data line) and SCLK (serial clock) are the three terminals required for communication with DS1302. Single byte or multiple byte mode are utilized for data transferring to or from clock or RAM.
