Specification

Description

DS1302 RTC Module is containing a real-time clock/calendar and 31 bytes of static RAM, communicating through serial interface simple and single-chip microcomputer. It is made of high-quality material. Clock /RAM read/write data to a byte character set or as many as 31-byte communication. DS1302 work power consumption is very low to keep the data and clock information when power is less than 1mW

The real-time clock/calendar circuit provides seconds, hours, days, weeks, months, years of information, a number of days in the month, and a leap year can automatically adjust. The clock operation instructions through the AM/PM decided to use 24 or 12-hour format.

Between DS1302 and single-chip microcomputer can simply use synchronous serial communication method, only three lines:
(1) RST
(2) I/O reset the data line
(3) SCLK serial clock.

Wiring method (to provide procedures, for example, can pick up any IO port, in the procedure to modify the port definitions :
VCC:+5V/3.3V
GND: GND
CLK: P02
DAT: P01
RST: P00

Feature

  • The real-time clock counts minutes, seconds, date, hours, month day of the week, year, and leap-year compensation up to 2100.
  • 318 temporary data storage RAM
  • Working current of 2.0V, less than 300nA
  • Read / Write clock or RAM data with two kinds of mode of single-byte transfer mode and multi-byte character set
  • 8 pin DIP package or optional 8 pin SOIC package based on the surface assembly
  • Simple 3 wire interface
  • Compatible with TTL Vcc=5V
  • Double power supply pipe for main power and backup power supply.

Note:
1. VCC and GND do not reverse, so as not to burn the chip
2.51 SCM P0 port to receive a pull-up resistor, if your computer is not connected pull-up resistor, the data can be the string to the other port.

Technical Details

  • Input Supply Voltage (VDC) : 3.3
  • Operating Voltage (VDC) : 2V ~ 5.5
  • Operating Temperature (°C) : -40 to 85
  • Storage condition (℃) : -55 to 125

Very handy module

This is a module that does not use SMD components and also no unwanted EERPOM which comes with other versions in market. Since regular components are used very easy for troubleshooting by DIY people.
