Supervisory Circuits with I
32K CMOS EEPROM
DESCRIPTION
The CAT1320 and CAT1321 are complete memory and
supervisory solutions for microcontroller-based systems.
A 32kbit 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 400kHz I
The CAT1320 provides a precision V
and drives an open drain output, RESET low whenever
V
The CAT1321 provides a precision VCC sense circuit
that drives an open drain output, RESET high whenever
V
The power supply monitor and reset circuit protect
memory and system controllers during power up/down
and against brownout conditions. Five reset threshold
voltages support 5V, 3.3V and 3V 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.
The CAT1320/21 memory features a 64-byte page. In
addition, hardware data protection is provided by a V
sense circuit that prevents writes to memory whenever V
falls below the reset threshold or until V
threshold during power up.
Available packages include an 8-pin DIP, SOIC, TSSOP
and 4.9 x 3mm TDFN.
