DS1302+ More Information

DS1302 Trickle-Charge Timekeeping Chip: Maxim Integrated DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar (RTC) and 31 bytes of static RAM. The DS1302 trickle-charge timekeeping chip communicates with a microprocessor via a simple serial interface. The RTC on this Maxim Integrated IC trickle-charge timekeeping chip provides seconds, minutes, hours, day, date, month, and year information. The end of month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial communication. Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1µW. This Maxim Integrated IC timekeeping chip also features dual power pins for primary and backup power supplies, programmable trickle charger for Vcc1, and seven additional bytes of scratchpad memory.

Maxim Real Time Clocks (RTC): Maxim Integrated Real-time Clocks (RTCs) are offered in a wide range of low power, highly accurate, small packages, and MEMs-based ICs. RTC ICs measure time, even when the power of the main device is off, so an auxiliary battery or supercapacitor are required. Power consumption is a key factor in most RTC designs, but accuracy and small package size are also important. The latest RTC ICs reduce package pin count by supporting a serial interface.Learn More
