DESCRIPTION
The CAT130xx (see table below) are memory and
supervisory solutions for microcontroller based
systems. A CMOS serial EEPROM memory and a
system power supervisor with brown-out protection
are integrated together. Memory interface is via
Microwire serial protocol.
The CAT130xx provides a precision V
CC
sense circuit
with two reset output options: CMOS active low output
or CMOS active high. The RESET output is active
whenever V
CC
is below the reset threshold or falls
below the reset threshold voltage.
The power supply monitor and reset circuit protect
system controllers during power up/down and against
brownout conditions. Seven reset threshold voltages
support 5V, 3.3V, 3V and 2.5V systems. If power
supply voltages are out of tolerance reset signals
become active, preventing the system microcontroller,
ASIC or peripherals from operating. Reset signals
become inactive typically 240ms after the supply
voltage exceeds the reset threshold level.

Note:
When the ORG pin is connected to V
CC
, the x16 organization is
selected. When it is connected to ground, the x8 pin is selected. If
the ORG pin is left unconnected, then an internal pullup device will
select the x16 organization.
