Pin Description
Symbol
SCL
Pin Name
Shift clock input This pin is used to input shift clock pulses to synchronize data input/output to
and from the SDA pin with this clock. Up to 6V beyond VDD may be input.
Serial input
output
clock pulses from the SCL pin. Up to 6V beyond VDD may be input. This
pin functions as an Nch open drain output.
Description
SDA
This pin inputs and outputs written or read data in synchronization with shift
/INTR
Interrupt
output
This pin outputs periodic interrupt pulses and alarm interrupt (ALARM_A,
ALARM_B) to the CPU. This pin is off when power is activated from 0V.
This pin functions as an Nch open drain output.
This pin outputs 32.768kHz pulses (when 32.768kHz crystal is used),
It outputs 32.768kHz when power source is activated from 0V. This pin
functions as an CMOS push-pull output.
These pins configure an oscillator circuit by connecting a 32.768kHz or
32.000kHz crystal oscillator between the OSCIN–OSCOUT pins.
(Any other oscillator circuit components are built into the RS5C372B.)
