Features
1. An RTC-DS1302 module that uses a DS1302 serial real-time clock (RTC) chip.
2. The RTC counts seconds, minutes, hours, date of the month, day of the week, month, and year leap-year compensation valid up to the year 2100.
3. It operates in either the 24-hour or 12-hour format (with an AM/PM indicator).
4. High performance, low power consumption; with 31 bytes of static RAM.
5. Working voltage: 2.5V ~ 5.5V; PCB size: 2.5 x 2.5 cm.
Introduction
1. Adopt the universal 32.768kHz crystal oscillator.
2. With a button cell holder for LIR2032 rechargeable Li-ion battery.
3. Use three lines (CE, I/O, SCLK) to synchronously communicate with CPU, or have a 3-wire interface; support clock signals or RAM data under a multi-byte mode (burst).
4. 5-Pin anti-reverse cable included.
5. Operating temperature: 0°C ~ +70°C.
6. Power: < 1mW (data and clock information stored).
Application
* Hand-hold devices
* Electronic watch
* Electronic alarm
