The AT93C46-10TC is a 1Kbit (128 x 8 or 64 x 16) Serial EEPROM from Microchip Technology (formerly Atmel). It's designed for low-voltage, low-power applications, providing a reliable non-volatile memory solution. The device utilizes a 3-wire serial interface for communication, making it easy to integrate into various microcontrollers and embedded systems.

Applications

• Storing configuration data in electronic devices.
• Storing serial numbers or identification codes.
• Storing calibration data.
• Storing user preferences.
• Data logging.

Features

• 1Kbit (128 x 8 or 64 x 16) EEPROM.
• Low-voltage operation (2.7V to 5.5V).
• 3-wire serial interface.
• Self-timed write cycle.
• High reliability with 1,000,000 erase/write cycles.
• Data retention of 100 years.
• Available in various packages, including TSSOP and SOIC.

Benefits

• Non-volatile memory ensures data is retained even when power is removed.
• Low-voltage operation makes it suitable for battery-powered devices.
• Simple 3-wire interface simplifies integration with microcontrollers.

• Small package sizes allow for use in space-constrained applications.
• Cost-effective solution for storing small amounts of data.

Additional Details

The AT93C46-10TC supports both ORG mode (x8 or x16 organization) which is selectable via an external pin. The device features a self-timed write cycle, eliminating the need for external timing circuits. It also has built-in protection against accidental writes during power-up. The operating temperature range is typically -40°C to +85°C. As an End-of-Life product, it's recommended to consider newer memory solutions for new designs; however, it may still be required for maintaining older systems or products that have not been redesigned.
