Carrier Frequency Generator
One 8-bit counter with auto-reload function and
one-shot or repeat control (Counter A)
Basic Timer and Timer/Counters
One programmable 8-bit basic timer (BT) for
oscillation stabilization control or watchdog timer
(software reset) function
One 8-bit timer/counter (Timer 0) with three
operating modes: Interval mode, Capture and
PWM mode.
One 16-bit timer/counter (Timer1) with two
operating modes: Interval and Capture mode.
One 16-bit timer/counter (Timer2) with two
operating modes: Interval and Capture mode.
Back-up Mode
When V
DD
is lower than V
LVD
, the chip enters
Back-up mode to block oscillation and reduce the
current consumption.
In S3F80JB, this function is disabled when
operating state is “STOP mode”.
When reset pin is lower than Input Low Voltage
(V
IL
), the chip enters Back-up mode to block
oscillation and reduce the current consumption.
Analog Voltage Comparator
4-bit resolution: 16-step variable reference
voltage, 150mV Input Voltage Accuracy (worst
case)
4-channel mode: CIN0-3, Internal reference
voltage generator
3-channel mode: CIN0-2, External reference
voltage source (CIN3) supply
