DS1302 main performance indicators:
★ The real-time clock has the ability to calculate seconds, minutes, hours, days, weeks, months, and years before 2100 years, as well as the ability to adjust for the following year.
★ 31 8-bit temporary data storage RAM
★ Serial I/O port method minimizes the number of pins
★ Wide working voltage 2.0 5.5V
★ Less than 300nA when working current is 2.0V
★ There are two ways of transferring single-byte transfer and multi-byte transfer character groups when reading/writing clock or RAM data.
★ 8-pin DIP package or optional 8-pin SOIC package based on surface mount
★ Simple 3-wire interface
★ Compatible with TTL Vcc=5V
★ Optional industrial temperature range -40 85
★ Dual power supply tube for mains and backup power supply
The parameters of the DS1302 real-time clock module are as follows:
1.PCB is a single panel, size: 44mm*23mm*1.6mm
2. With 4 positioning holes, diameter 3.1mm
3. The backup battery is genuine celestial CR2032, voltage 3V, current 260mAh, non-rechargeable battery. Theoretical data retention time is greater than 10 years!
4. Crystal oscillator 32.768KHz, Japan imported crystal oscillator, matching capacitor is 6pF, size 2*6mm
5.DS1302 is a 8-pin in-line large-scale domestic chip. There is an IC holder under the chip, which is convenient for replacement and plugging and unloading of chips.
6. Module working voltage is compatible with 3.3V/5V, can be connected with 5V and 3.3V MCU
7. Working temperature: 0°---70°
Wiring method (taking the provided program as an example, you can connect any IO port and modify the port definition in the program):
VCC→ 5V/3.3V
GND→GND
CLK→P02
DAT→P01
RST→P00
Precautions:
1. Do not reverse the VCC and GND to avoid burning the chip.
The 2.51 MCU P0 port needs to be connected with a pull-up resistor. If your MCU does not have a pull-up resistor, you can connect the data cable to other ports.
