CAT140xx
Voltage Supervisor with I 2 C
Serial CMOS EEPROM
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 (100 kHz) as well as fast (400 kHz) 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 5 V, 3.3 V, 3 V and 2.5 V
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
240 ms after the supply voltage exceeds the reset threshold level.
