Description
Serial
Clock Line
The SCL pin is used to input clock pulses synchronizing the input and output
of data to and from the SDA pin. Allows a maximum input voltage of 5.5
volts regardless of supply voltage.
The SDA pin is used to input or output data intended for writing or reading in
synchronization with the SCL pin. Up to 5.5v beyond VDD may be input.
This pin functions as an Nch open drain output.
The /INTRA pin is used to output periodic interrupt signals to the CPU and
alarm interrupt (Alarm_D) signals. Disabled at power-on from 0 volts. Nch.
open drain output.
The /INTRB pin is used to output alarm interrupt (Alarrm_W) signals to the
CPU. Disabled at power-on from 0 volts. Nch. open drain output.
The 32KOUT pin is used to output 32.768-kHz clock pulses. Enabled at
power-on from 0 volts. CMOS output. The output is disabled if the CLKC pin
is set to Low or open.
The CLKC pin is used to control output of the 32KOUT pin. The clock output
is disabled and held low when the pin is set to low or open. Incorporates a
pull-down resistor.
The OSCIN and OSCOUT pins are used to connect the 32.768-kHz crystal
oscillator (with all other oscillation circuit components built into the
RV5C386A).
The VDD pin is connected to the power supply.
