CAT93C57S-TE13

Memory IC Overview

The CAT93C57S-TE13 is a 2-kbit CMOS Serial EEPROM manufactured by onsemi. It features Microwire bus interface compatibility and offers selectable memory organization of either 128 registers of 16 bits or 256 registers of 8 bits, determined by the ORG pin state. The device supports high-speed operation with a maximum clock frequency of 2 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. It includes self-timed internal write cycles with auto-clear functionality and incorporates on-chip Power-On Reset circuitry to prevent erroneous states during power-up.

Memory IC Feature Summary

• Microwire serial interface supporting sequential read operations
• Self-timed internal write mechanism with automatic cycle termination
• Configurable memory width via hardware pin selection
• Integrated Power-On Reset logic for system reliability

Memory IC Applications

• Data storage in industrial control systems
• Configuration parameter retention in embedded controllers
• Calibration data storage for sensor interfaces
• Device identification and settings in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'S' against official onsemi documentation to confirm package type and temperature grade. Ensure the TE13 tape-and-reel designation matches manufacturing requirements. Confirm RoHS compliance status as historical records may vary. Cross-reference the exact part number with current datasheets to validate active status and availability constraints before procurement.

Memory IC Selection Notes

Select this component when a Microwire-compatible serial EEPROM is required for low-pin-count applications. The choice between x8 and x16 organization depends on the host controller's addressing capability. Verify that the operating voltage aligns with the 1.8 V to 5.5 V specification. Consider the 2 MHz clock speed for timing constraints in high-frequency serial communication environments.

Memory IC Part Context

This device belongs to the CAT93C56/57 family of 2-kbit serial EEPROMs. The CAT93C57 variant specifically provides 16-bit word width options alongside the standard 8-bit configuration. It utilizes CMOS technology for low power consumption and is available in multiple package formats including SOIC and TSSOP variants depending on the suffix code.

Memory IC Replacement Considerations

Direct substitutes include other CAT93C57 variants from onsemi with compatible pinouts and electrical characteristics. Verify interface protocol compatibility with existing Microwire controllers. Check voltage ranges and package dimensions to ensure mechanical fit.
