CAT1320, CAT1321
Supervisory Circuits with
I 2 C Serial 32K CMOS
EEPROM
Description
The CAT1320 and CAT1321 are complete memory and supervisory
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 2 C bus.
The CAT1320 provides a precision V CC sense circuit and drives an
open drain output, RESET low whenever V CC falls below the reset
threshold voltage.
The CAT1321 provides a precision VCC sense circuit that drives an
open drain output, RESET high whenever V CC falls below the reset
threshold voltage.
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 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.
The CAT1320/21 memory features a 64 ? byte page. In addition,
hardware data protection is provided by a V CC sense circuit that
prevents writes to memory whenever V CC falls below the reset
threshold or until V CC reaches the reset threshold during power up.
Available packages include an 8 ? pin DIP, SOIC, TSSOP and
4.9 x 3 mm TDFN.
