The Catalyst Semiconductor CAT59C11KI is a non-volatile static RAM (NVSRAM) device with a built-in real-time clock (RTC). It combines high-speed SRAM with a non-volatile EEPROM backup, ensuring data retention even when power is lost. The integrated RTC provides accurate timekeeping functionality.

Applications

• Industrial Control Systems: Used for storing critical data and maintaining accurate time in industrial automation and control equipment.
• Point-of-Sale (POS) Terminals: Employs for secure storage of transaction data and time-stamping of sales records.
• Medical Devices: Utilized in medical instruments for storing patient data and tracking events with precise timestamps.
• Networking Equipment: Integrated into routers, switches, and other network devices for configuration storage and real-time logging.
• Data Loggers: Used in data logging applications for preserving collected data and maintaining accurate time records.

Features

• Non-Volatile SRAM: Combines SRAM for fast access with EEPROM for non-volatile data storage.
• Integrated Real-Time Clock (RTC): Provides accurate timekeeping with battery backup.
• Automatic Store on Power Down: Automatically stores SRAM data to EEPROM when power is lost.
• Software Control: Allows software control of store and recall operations.
• Low Power Consumption: Designed for efficient power usage, extending battery life.
