Description
solutions for microcontroller−based systems. A 32 kbit serial
EEPROM memory and a system power supervisor with brown−out
protection are integrated together in low power CMOS technology.
Memory interface is via a 400 kHz I

system controllers during power up/down and against brownout
conditions. Five reset threshold voltages support 5 V, 3.3 V and 3 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
200 ms after the supply voltage exceeds the reset threshold level. With
both active high and low reset options, interface to microcontrollers
and other ICs is simple. In addition, the RESET (CAT1320) pin can be
used as an input for push−button manual reset capability.
