DS1305E+T&R Frequently Asked Questions (FAQ)
-
The recommended crystal oscillator frequency for the DS1305E+T&R is 32.768 kHz.
-
To ensure correct startup, the VCC pin should be powered up before the XTAL pin, and the RST pin should be pulled high during power-up.
-
The RST pin is an active-low reset input that resets the device when pulled low. It can be used to reset the device during power-up or to reset the clock during normal operation.
-
The clock can be set by writing the desired time and date to the device's registers using the I2C interface. The device has a built-in oscillator that drives the clock circuitry.
-
The internal oscillator of the DS1305E+T&R has an accuracy of ±20 ppm over the operating temperature range of -40°C to +85°C.
