DESCRIPTION
The CAT1163 is a complete memory and supervisory
solution for microcontroller-based systems. A serial
EEPROM memory (16K) with hardware memory write
protection, a system power supervisor with brown out
protection and a watchdog timer are integrated together
in low power CMOS technology. Memory interface is via
an I
2
C bus.
The 1.6-second watchdog circuit returns a system to a
known good state if a software or hardware glitch halts
or “hangs” the system. The CAT1163 watchdog monitors
the WDI input pin.
The power supply monitor and reset circuit protects
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 signals,
interface to microcontrollers and other ICs is simple. In
addition, a reset pin can be used as debounced input for
push-button manual reset capability.
The CAT1163 memory features a 16-byte page. In addition,
hardware data protection is provided by a write protect pin
WP and 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 and a surface
mount, 8-pin SO package.
