New Arrival RTC DS1302 Real Time Clock Module

Description:

The DS1302 is a trickle charge clock chip from DALLAS that contains a real-time clock / calendar and 31 bytes of static RAM to communicate with the microcontroller through a simple serial interface. Real-time clock / calendar circuit provides seconds, minutes, hours, days, weeks, months, years of information, the number of days per month and leap year number of days can be adjusted automatically. The clock operation can be determined by the AM / PM indication in a 24 or 12 hour format. (1) RST reset (2) I / O data lines (3) SCLK serial clock. (1) RST reset (2) I / O data lines (3) SCLK serial clock. Clock / RAM read / write data in a byte or up to 31 bytes of character group communication. DS1302 power consumption is very low to maintain data and clock information when the power is less than 1mW

Features:

real-time clock with 2100 can be calculated before the seconds, minutes, hours, days, weeks, months, years of ability, as well as leap year adjustment 31 8-bit temporary data storage RAM Serial I / O port mode makes the pin count the least Wide operating voltage 2.0V working current 2.0V, less than 300nA Read / write clock or RAM data, there are two transfer methods Single byte transfer and multi-byte transmission character group mode 8-pin DIP package or optional 8-pin SOIC package according to surface mount simple 3-wire interface compatible with TTL Vcc = 5V Optional industrial temperature range -40 +85 dual power supply for the main power supply and backup power supply DS1302 real-time clock module parameters are as follows: 1.PCB for the single-panel, size: 44mm * 23mm * 1.6mm 2. With 4 positioning holes, diameter 3.1mm 3. Backup battery for the authentic celestial sphere CR2032, voltage 3V, current 260mAh, non-rechargeable battery. Theoretical data retention time greater than 10 years! 4. Crystal 32.768KHz, Japan imported crystal, matching capacitance of 6pF, size 2 * 6mm 5.DS1302 8-pin plug-in large chip made, the chip below IC Block, easy to replace and plug the chip 6. Module operating voltage is compatible with 3.3V / 5V, and 5V and 3.3V single-chip connection 7. Operating temperature: 0 ° — 70 °

Wiring method (to provide the program as an example, you can access any IO port, modify the port definition in the program can be):

VCC → + 5V / 3.3V GND → GND CLK → P02 DAT → P01 RST → P00 Precautions: 1.VCC and GND do not reverse, so as not to burn the chip 2.51 single-chip P0 port need to connect pull-up resistor, if your microcontroller is not connected to pull-up resistor, you can connect the data line to other ports Payment methods
