CAT28C16AN-20 – CATALYST SEMICONDUCTOR INC

Overview

The CAT28C16AN-20, a 16Kb EEPROM from CATALYST SEMICONDUCTOR INC, excels in providing non-volatile data storage with a parallel interface. Its critical operational characteristic lies in its ability to retain data indefinitely without power, crucial for configuration settings and calibration parameters. A key design consideration for engineers is the trade-off between its 200ns access time and the potential for write-cycle endurance limitations, necessitating careful firmware design to manage data updates and prevent premature wear in high-frequency write applications.

Key Features

• 16Kb (2K x 8-bit) EEPROM Memory
• 200ns Maximum Access Time
• Single 5V Operating Voltage
• Parallel Interface (28-pin PLCC32 package)
• Industrial Temperature Range: 0°C to 70°C
• High Endurance (typically 100,000 write cycles per byte)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Storing device configuration and calibration data in embedded systems
• Non-volatile parameter storage for industrial control modules
• Maintaining user settings in consumer electronics requiring persistent memory
• Holding firmware checksums and bootloader parameters in microcontrollers
