23. Power Monitor
23.1
4337K–USB–04/08
Description
The POR/PFD function monitors the internal power-supply of the CPU core memories and the
peripherals, and if needed, suspends their activity when the internal power supply falls below a
safety threshold. This is achieved by applying an internal reset to them.
By generating the Reset the Power Monitor insures a correct start up when AT89C5131 is pow-
ered up.
In order to startup and maintain the microcontroller in correct operating mode, V
bilized in the V
compatible with logic level VIH/VIL.
These parameters are controlled during the three phases: power-up, normal operation and
power going down. See Figure 23-1.
Figure 23-1. Power Monitor Block Diagram
Note:
The Voltage regulator generates a regulated internal supply for the CPU core the memories and
the peripherals. Spikes on the external Vcc are smoothed by the voltage regulator.
The Power fail detect monitor the supply generated by the voltage regulator and generate a
reset if this supply falls below a safety threshold as illustrated in the Figure 23-2 below.
