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

C protocol.

The CAT140xx provides a precision V

sense circuit

with two reset output options: CMOS active low output

or CMOS active high. The RESET output is active

whenever V

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.
