The CAT93C46KI-TE13 is a 1K-bit Microwire Serial EEPROM from Catalyst Semiconductor (now part of ON Semiconductor). This device is a small, low-power, non-volatile memory that can be electrically erased and reprogrammed. It uses a simple Microwire serial interface for communication, making it easy to interface with microcontrollers and other digital systems. This EEPROM is suitable for storing configuration data, serial numbers, calibration constants, and other small amounts of persistent data.

Applications

• Storage of Configuration Data.
• Storage of Calibration Constants.
• Storage of Serial Numbers and Identification Codes.
• Data Logging.
• Storage of User Preferences.

Features

• 1K-bit (128 x 8 or 64 x 16) Serial EEPROM.
• Microwire Serial Interface (CS, SK, DI, DO).
• Low Voltage Operation (typically 2.5V to 5.5V).
• Low Power Consumption.
• Self-Timed Erase/Write Cycles.
• High Reliability (typically 1,000,000 Erase/Write Cycles).
• Data Retention: 100 years.
• Small SOIC or TSSOP package.

Benefits

• Non-volatile storage of data even when power is removed.
• Easy to interface with microcontrollers using the Microwire serial interface.
• Low power consumption for battery-powered applications.
• High reliability ensures data integrity.
• Small size allows for compact designs.

Additional Details

The CAT93C46KI-TE13 is organized as either 128 bytes of 8 bits each or 64 words of 16 bits each, selectable via an external pin. The Microwire serial interface consists of four signals: Chip Select (CS), Serial Clock (SK), Data In (DI), and Data Out (DO). The device supports standard Microwire read and write operations. The self-timed erase/write cycles simplify the programming process. The EEPROM has a high endurance, typically 1,000,000 erase/write cycles, and a data retention of 100 years, ensuring long-term data storage. It is available in small SOIC and TSSOP packages. The TE13 suffix indicates a specific package and tape & reel option. Due to its end-of-life status, designers should consider alternative EEPROM devices for new projects. However, it may still be necessary for maintaining existing systems.
