DS1302 real time clock ule
DALLAS DS1302 is the company launched trickle charge the clock chip, which contains 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 operation by AM / PM indicator decided to use 24 or 12 hour format. DS1302 between the microcontroller can simply adopt the way synchronous serial communication port only used three lines: (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 set type communication. DS1302 work to maintain low power consumption data and clock information when power is less than 1mW
DS1302 key performance indicators:
Real-time clock with energy calculations before 2100 seconds, minutes, hours, day, week, month, year capacity, as well as the ability to leap year adjustment
serial I / O ports such a way that a minimum number of pins
Wide operating voltage range 2.0 5.5V
2.0V, operating current of less than 300nA
Read / write clock or RAM data transfer e, there are two single-byte and multi-byte transfer e transmission character set
8-pin DIP package or an optional 8-pin SOIC surface mount package under
Simple 3-wire interface
Vcc = 5V and TTL compatible
Optional industrial temperature range of -40 to +85
Dual power tubes used for the main power supply and backup power supply
DS1302 real time clock ule parameters are as follows:
