Overview

Description
The CAT1161/2 is a comprehensive memory and supervisory solution for microcontroller-based systems. It integrates a 16K serial EEPROM memory with hardware write protection, a system power supervisor with brownout protection, and a watchdog timer (CAT1161 only) into a low-power CMOS technology. The memory interface is via an I²C bus.

Features
Watchdog monitors SDA signal (CAT1161)
400 kHz I²C bus compatible
2.7 V to 6 V operation
Low power CMOS technology
16-byte page write buffer
Built-in inadvertent write protection
Vcc lock out
Write protection pin (WP)
Active high or low reset
Precision power supply voltage monitor (5 V, 3.3 V, and 3 V systems)
Five threshold voltage options
1,000,000 program/erase cycles
Manual reset
100-year data retention
8-pin DIP or 8-pin SOIC package
Commercial and industrial temperature ranges
Pb-free, halogen-free/BFR-free, and RoHS compliant

Applications
Microcontroller-based systems
Memory and supervisory solutions
Power supply monitoring
Reset control
Watchdog timers
