Data Sheet
PT7C43390
2-Wire Real-time Clock Module
Function Block
Function Description
Overview of Functions
Clock function
CPU can read or write data including the year (last two digits), month, date, day, hour, minute, and second. Any (two-digit) year
that is a multiple of 4 is treated as a leap year and calculated automatically as such until the year 2099.
Alarm function
This device has two alarm system (Alarm 1 and Alarm 2) that outputs interrupt signals from INT1 or INT2 to CPU when the date,
day of the week, hour, minute or second correspond to the setting. Each of them may output interrupt signal separately at a
specified time. The alarm is be selectable between on and off for matching alarm or repeating alarm.
Programmable square wave output
Square wave output at pin 1 or pin 5. Six frequencies are selectable: 1, 2, 4, 8, 16, 32.768kHz.
Interface with CPU
For PT7C43390:
2-wire I2C interface.
Calibration function
With the calibration bits properly set, the accuracy can be improved to better than ±2 ppm at 25°C.
