FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
SMARTMOS ANALOG CONTROL IC
INTERNAL REGULATORS & SAFETY:
VOLTAGE REGULATION
The voltage regulator circuitry provides the regulated
voltage for the Analog IC, as well as the VDD/VSS rails for
the core IC. The on-chip regulator consists of two elements,
the main regulator, and the low voltage reset circuit. The VDD
regulator accepts an unregulated input supply and provides a
regulated VDD supply to all digital sections of the device. The
output of the regulator is also connected to the VDD pin to
provide the 5.0 V to the microcontroller.
SWITCHED VDD
This function provides a switchable +5.0 V VDD rail for an
external load.
WATCHDOG TIMER
The watchdog timer module generates a reset, in case of
a watchdog timeout or wrong watchdog timer reset. A
watchdog reset event will reset all registers in the SPI,
excluding the RSR.
RESET, IRQ & WAKE-UP
There are several functions on the Analog IC that can
generate a reset or wake-up signal to the core IC. There is a
pin that is used to detect an external wake-up event. The
Reset signal has many possible sources in the Analog IC
circuitry. The IRQ function on the Analog IC will notify the
core IC of pending system critical conditions.
