PCF2123BS/1,518 Frequently Asked Questions (FAQ)
-
The recommended crystal oscillator frequency for PCF2123BS/1,518 is 32.768 kHz.
-
The PCF2123BS/1,518 can be configured for 12-hour or 24-hour clock mode by setting the appropriate bits in the Hour Register (HR). For 12-hour mode, set bit 6 (12/24) to 0, and for 24-hour mode, set it to 1.
-
The RST (Reset) pin on the PCF2123BS/1,518 is an active-low input that resets the device when pulled low. It is used to reset the device and clear all registers to their default values.
-
The PCF2123BS/1,518 uses an I2C interface for reading and writing data. The device has a 7-bit slave address, and data is transferred in bytes. The master device (e.g., a microcontroller) sends a start condition, followed by the slave address, register address, and data bytes.
-
The PCF2123BS/1,518 has a typical current consumption of 0.4 μA in standby mode and 1.5 μA in active mode, with a supply voltage range of 1.5 V to 5.5 V.
