■ Built-in inadvertent write protection

— V_CClock out

■ 100 Year data retention

■ 8-pin DIP or 8-pin SOIC

■ Commercial and industrial temperature ranges

— Write protect pin, WP

DESCRIPTION

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 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

protectionandawatchdogtimerareintegratedtogether

inlowpowerCMOStechnology. Memoryinterfaceisvia

an I²C bus.

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_CCsense circuit that prevents writes to

memory whenever V_CCfalls below the reset threshold or

until V_CCreaches the reset threshold during power up.

The 1.6-second watchdog circuit returns a system to a

known good state if a software or hardware glitch halts

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

Available packages include an 8-pin DIP and a surface

mount, 8-pin SO package.
