The real-time clock / calendar circuit provides seconds, minutes, hours, day, week, month, year, and can automatically adjust the monthly number of days and the number of days of the leap year. Clock operation by the AM / PM indication, the decision to adopt a 24 or 12-hour format. Between the DS1302 and the microcontroller can simply synchronous serial communication only used three lines of: (1) RST Reset (2) I / O data line (3) SCLK Serial Clock. Clock / RAM read / write data to a byte or character groups of up to 31 bytes of communication. DS1302 working when the power consumption is very low to maintain data and clock information when the power is less than 1mW DS1302 main performance indicators: ? real-time clock can be calculated before 2100 seconds, minute, hour, day, week, month, year capacity, as well as leap year adjustment capacity ? 31 8-bit temporary data storage RAM ? serial I / O port, making the least number of pins ? wide range of operating voltage 2.0 5.5V ? Operating Current 2.0V, less than 300nA ? read / write clock or RAM data when there are two kinds of transmission mode in a single byte transfer and multi-byte the transmitted character group way ? 8-pin DIP package or an optional 8-pin SOIC package surface mount ? simple 3-wire interface ? Vcc = 5V TTL compatible ? Optional industrial temperature range of -40 to +85 ? dual supply pipe for the main power and backup power supply Notice: There is no battery in the package.
