FUNCTIONAL DESCRIPTION
PROCESSOR RESET
The CAT705, CAT706 & CAT813 detect supply
voltage (VCC) conditions that are below the specified
voltage trip value (VRST) and provide a reset output to
maintain correct system operation. On power-up,
RESET
(or RESET for the CAT813) are kept active for
a minimum delay tRP of 140ms after the supply voltage
(VCC) rises above VRST to allow the power supply and
processor to stabilize. When VCC drops below the
voltage trip value (VRST), the reset output signals
RESET
(or RESET) are pulled active. RESET
(or
RESET) is specifically designed to provide the reset
input signals for processors. This provides reliable
and consistent operation as power is turned on, off or
during brownout conditions by maintaining the
processor operation in known conditions.
MANUAL RESET
The CAT705, CAT706 & CAT813 each have a Manual
Reset (MR
) input to allow for alternative control of the
reset outputs. The MR
input is designed for direct
connection to a pushbutton (see Figure 1). The MR
input is internally pulled up by 52k resistor and must
be pulled low to cause the reset outputs to go active.
Internally, this input is debounced and timed such that
RESET
(or RESET) signals of at least 140ms
minimum will be generated. The min 140ms tRP delay
commences as the Manual Reset input is released
from the low level. (see Figure 2)
