CAT25C16SE-26628

Memory IC Overview

The CAT25C16SE-26628 is a 16-kbit serial electrically erasable programmable read-only memory (EEPROM) manufactured by onsemi. It features an SPI interface with a maximum clock frequency of 10 MHz and a typical access time of 40 ns. The device offers a memory organization of 2K x 8 bits and operates within a supply voltage range of 2.5 V to 6 V, supporting standard 3.3 V and 5 V logic levels. It is housed in a 16-pin SOIC package and ensures data retention for up to 100 years. The component supports write cycle times of 5 ms and maintains low power consumption characteristics suitable for embedded storage applications.

Memory IC Feature Summary

• Supports high-speed SPI serial communication interface
• Provides non-volatile data storage with long-term retention
• Compatible with standard 3.3 V and 5 V operating voltages

Memory IC Applications

• Embedded system configuration storage
• Industrial control parameter logging
• Consumer electronics firmware backup

Memory IC Procurement Notes

Verify the specific suffix 26628 against official onsemi documentation to confirm pinout and electrical specifications match your design requirements. Confirm end-of-life status or obsolescence notices prior to finalizing procurement plans. Ensure compatibility with existing SPI controller drivers and voltage levels during integration testing.

Memory IC Selection Notes

Select this component when a 16-kbit capacity is sufficient for application needs. The 10 MHz SPI speed offers faster performance compared to lower-frequency variants. The 16-pin SOIC package requires adequate PCB space consideration. Verify that the 2.5 V to 6 V operating range aligns with the target system's power supply architecture.

Memory IC Part Context

This part belongs to the CAT25C16 series of serial EEPROMs from onsemi. It shares functional similarities with other members of the family but differs in package type and specific electrical parameters defined by the SE-26628 designation. The series is designed for general-purpose non-volatile memory applications requiring reliable data retention.

Memory IC Replacement Considerations

Direct substitutes may include other CAT25C16 variants with compatible packages. Verify pin-to-pin compatibility and electrical specifications before substitution. Consult onsemi documentation for approved alternative part numbers.
