- 2.7V to 6.0V operation
- Low power CMOS technology
- 16-Byte page write buffer
- Built-in inadvertent write protection
- VCC lockout
- Write protect pin, WP
- Active high or low reset
- Precision power supply voltage monitor
- Compatible with 5V, 3.3V, and 3V systems
- Five threshold voltage options
- 1,000,000 Program/Erase cycles
- Manual reset
- 100 Year data retention
- 8-pin DIP or 8-pin SOIC
- Commercial and industrial temperature ranges

Application Scenarios

The CAT1163 is suitable for use in microcontroller-based systems that require memory and supervisory functions. It can be used in various applications, including but not limited to:

• - Industrial control systems
• - Automotive electronics
• - Consumer electronics
• - Medical devices

Comparison

- Integrated memory and supervisory solution
