EGP 20
See other suppliers →Description
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. Features Real-time clock counts minutes, seconds, date, hours, month day of the week, year and leap-year compensation upto 2100. Single and Multiple (Burst mode) data transfer for Read and Write of Clock or RAM data 31*8 battery-backed general purpose RAM Simple interface using 3-wire TTL-compatible 2V to 5.5V full operation Compact size Available Package: 8-pin DIP, 8-pin SO Technical Specifications Supply voltage (typically): 3.3V Voltage range on any pin (with respect to ground): -0.5V to 7.0°C Operating Temperature (Commercial): 0°C to +70°C Operating Temperature (Industrial): -40°C to +85°C Storage Temperature range: -55°C to +125°C Soldering Temperature: 260°C
