DS1302 real time clock module



DALLAS DS1302 is the company launched a trickle charge the clock chip , which contains a real-time clock / calendar and 31 bytes of static RAM, communicate via a simple serial interface 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 days can be automatically adjusted for leap year . Clock operation may indicate decided to use 24 or 12-hour format by AM / PM. Between the DS1302 can simply use synchronous serial microcontroller way to communicate , just use three port lines : (1) RST Reset (2) I / O data lines (3) SCLK Serial Clock . Clock / RAM read / write data up to a 31 -byte or byte character set mode of communication . DS1302 low power consumption while working to keep the data and clock information power of less than 1mW



DS1302 key performance indicators:

Real-time clock with before 2100 can be calculated in seconds, minutes , hours, days, weeks, months , years of capacity , as well as the ability to leap year adjustment

31 8 temporary data storage RAM

Serial I / O ports such a way that a minimum number of pins

Wide range of operating voltage 2.0 5.5V

When operating current 2.0V, less than 300nA

Read / There are two ways to send single-byte and multi-byte transfer mode transmission character set data write clock or RAM

8-pin DIP or optional 8- pin SOIC surface mount package according to

Simple 3-wire interface

Compatible with TTL Vcc = 5V

Optional industrial temperature range of -40 to +85

Dual power tube for the main power supply and backup power supply
