The 93CS46N is a 1K Microwire Serial EEPROM manufactured by Fairchild Semiconductor (now ON Semiconductor). It is a non-volatile memory device that can be electrically erased and reprogrammed. It communicates using the Microwire serial interface, making it suitable for applications where space and pin count are limited.

Applications:

• Storage of configuration data in embedded systems
• Parameter storage in industrial control equipment
• Calibration data storage in instrumentation
• Storage of serial numbers or identification codes
• Data logging applications

Features:

• 1K (128 x 8) bits of EEPROM memory
• Microwire serial interface
• Low voltage operation (typically 2.5V to 5.5V)
• Low power consumption
• Self-timed write cycle
• High endurance (typically 1 million erase/write cycles)
• Data retention (typically 100 years)
• 8-Pin PDIP, SOIC, and TSSOP packages

Benefits:

• Provides non-volatile storage for important data, even when power is removed.
• Simplifies communication with microcontrollers using a simple serial interface.
• Suitable for battery-powered and low-power applications.
• Reduces overall system power consumption.
• Eliminates the need for external timing components during write operations.
• Ensures reliable data storage over a long lifespan.
• Suitable for a wide range of operating conditions.
• Offers flexibility in terms of package options for different board layouts.

Technical Specifications:

While specific values can vary based on datasheet revisions and testing conditions, typical parameters include:

• Supply Voltage (VCC): Typically 2.5V to 5.5V
• Operating Temperature: -40°C to +85°C
• Write Cycle Time: Typically 5ms
• Standby Current: Typically less than 1µA
• Endurance: Typically 1,000,000 erase/write cycles per word
• Data Retention: Typically 100 years
