  • DS1302 is introduced trickle charge the clock chip, containing a real-time clock / calendar and 31 bytes of static RAM, via a simple serial interface
  • to communicate with the microcontroller. Real-time clock / calendar circuit provides seconds, minutes, hours, days, weeks, months, years of
  • information, the number of days per month and leap year automatically adjust the number of days. Clock can be done by the AM / PM or 12
  • decided to use 24 hour format. Between the DS1302 and the microcontroller can simply use the synchronous serial communication mode, used
  • only three port lines: (1) RST Reset (2) I / O data lines (3) SCLK serial clock. Clock / RAM read / write data to a byte or up to 31 bytes of character
  • set way communication. DS1302 low-power work to maintain the data and clock information when power is less than 1mW
  • Real time clock with the year 2100 to calculate the seconds, minutes, hours, days, weeks, months, years, the ability, as well as the ability to leap
  • year adjustment
  • 1.31 8 temporary data storage RAM
  • 2.Serial I / O port pin makes the least number of ways
  • 3.Wide range of operating voltage 2.0 5.5V
  • 4.Current 2.0V, less than 300nA
  • 5.Read / write clock or RAM data transmission when there are two single-byte transmit and multi-byte character sets transfer mode
  • 6.8-pin DIP package or optional 8-pin SOIC package assembly according to the surface
  • 7.simple 3-wire interface
  • 8.Vcc = 5V and TTL-compatible
  • 9.Optional industrial temperature range -40 to +85
  • 10.Dual power tube for the main power and backup power supply

  • PCB a single panel, size: 42mm * 24mm * 12mm(max)
  • Color:green (as the picture shows)
  • with 4 holes, about 3.1mm in diameter
  • genuine spare battery for the celestial sphere CR2032, Voltage 3V, current is 260mAh, non-rechargeable batteries.
  • Crystal 32.768KHz, matching capacitance 6pF, size 2 * 6mm
  • DS1302 made large 8-pin DIP chip, chip, IC Block below for easy replacement and plug the chip
  • module operating voltage compatible 3.3V/5V, 5V and 3.3V microcontrollers can be connected with
  • Operating temperature: 0– 70
  • Wiring (to provide the program, for example, can take any IO port, the port defined in the program can be modified):
  • VCC → +5 V/3.3V
  • GND → GND
  • CLK → P02
  • DAT → P01
  • RST → P00
  • 1.VCC and GND must not be reversed, or it will burn the chip
  • 2.51 MCU P0 port requires a pull-up, if your single-chip pull-up resistor is not connected, you can port the data cable to the other
  • DS1307
  • This is the DS1307 Real Time Clock developed by one of our designer Waiman. The module comes fully assembled and pre-programmed with the current time (ok, so it ‘s our current time-MST). The DS1307 is accessed via the I2C protocol.
