CAT25010VI-G

Memory IC Overview

The CAT25010VI-G is a 1-Kb (128 x 8) Serial CMOS EEPROM manufactured by onsemi. It supports the SPI protocol with clock frequencies up to 20 MHz at 5 V and operates within a supply voltage range of 1.8 V to 5.5 V. The device features a 16-byte page write buffer, self-timed write cycles, and hardware/software protection including block write protection. It offers 1,000,000 program/erase cycles and 100-year data retention. Packaged in an SOIC-8 (V suffix), it supports industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature ranges.

Memory IC Feature Summary

• Supports SPI modes (0,0) and (1,1) with clock frequencies up to 20 MHz
• Features hardware and software write protection with partial or full array blocking
• Includes a 16-byte page write buffer for efficient data programming
• Provides HOLD input capability to pause serial communication without retransmission

Memory IC Applications

• Data storage in embedded systems requiring non-volatile memory
• Configuration parameter storage in industrial control devices
• Calibration data retention in sensor interfaces
• Device identification and security code storage in consumer electronics

Memory IC Procurement Notes

Verify the specific ordering suffix 'VI' corresponds to the SOIC-8 package and the required temperature range. Confirm that the 'G' suffix indicates lead-free and RoHS compliance as specified in the datasheet. Ensure the procurement quantity matches the tape and reel shipping configuration if applicable. Cross-reference the manufacturer part number with official onsemi documentation to confirm current production status and availability.

Memory IC Selection Notes

Select this component when a 1-Kb capacity is sufficient for application requirements. Choose the VI suffix specifically for the SOIC-8 package format. Verify that the operating environment falls within the supported temperature range of -40°C to +125°C for the extended grade. Ensure the system design accommodates the 1.8 V to 5.5 V supply voltage range and utilizes the SPI interface correctly.

Memory IC Part Context

This device belongs to the CAT25010/20/40 family of Serial CMOS EEPROMs from onsemi. The family shares common architectural features such as SPI compatibility, write protection mechanisms, and low power consumption. Variations within the family primarily differ in memory density (1-Kb, 2-Kb, 4-Kb) and available package options. The CAT25010 represents the entry-level density option in this series.

Memory IC Replacement Considerations

Direct replacements include other members of the CAT25010/20/40 family with compatible pinouts and electrical characteristics. Verify that any substitute part maintains the same SPI mode support and voltage range. Check for equivalent package dimensions if physical replacement is required.
