This custom designed module for the DS1302 Real Time Clock. Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial communication. Only three wires are required to communicate with the clock / RAM: RST, I / O (data line), and SCLK (serial clock).

Features of Real-Time Clock Module DS1302:

• 31 x 8 Battery - Backed General - Purpose RAM.
• Serial I / O for Minimum Pin Count.
• 2.0 V to 5.5 V Full Operation.
• Uses Less than 300 nA at 2.0 V.
• Single - Byte or Multiple-Byte (Burst Mode) Data Transfer for Read or Write of Clock or RAM Data.
• Simple 3 - Wire Interface.
• TTL - Compatible ( VCC = 5 V ).
• Optional Industrial Temperature Range: -40 °C to +85 °C.
• DS1202 Compatible.

Applications of Real-Time Clock Module DS1302:

• It is used in different applications for remote controlled purposes.
