PIN CONFIGURATION
DESCRIPTION
The CAT140xx (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 both the standard
(100kHz) as well as fast (400kHz) I 2 C protocol.
The CAT140xx 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.
