CAT25256VE-GT3

Memory IC Overview

The CAT25256VE-GT3 is a 256-Kb (32K x 8) Serial EEPROM from onsemi, utilizing SPI interface protocols. It operates within a supply voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 20 MHz at 5 V. The device features a 64-byte page write buffer, hardware/software write protection, and an additional identification page with permanent write protection capability. It includes On-Chip ECC for high reliability applications.

Memory IC Feature Summary

• Supports SPI modes (0,0) and (1,1) with clock speeds up to 20 MHz
• Includes 64-byte page write buffer and self-timed write cycles
• Features hardware and software block write protection for quarter, half, or full array
• Incorporates On-Chip Error Correction Code (ECC) logic

Memory IC Applications

• High reliability data storage systems requiring error correction
• Industrial control devices operating in extended temperature ranges
• Embedded systems needing persistent configuration storage
• Automotive electronics compliant with AEC-Q100 standards

Memory IC Procurement Notes

Verify the specific suffix 'V' corresponds to the SOIC-8 package type as defined in the ordering information table. Confirm the revision level (Rev E) if ECC functionality is required, as mature products lack this feature. Ensure compatibility with the NiPdAu lead finish specified for this part number.

Memory IC Selection Notes

Select this component when SPI compatibility and high-speed operation up to 20 MHz are required. The SOIC-8 package is suitable for surface mount assembly. Consider the Rev E designation for applications necessitating On-Chip ECC support and the dedicated Identification Page feature.

Memory IC Part Context

This device belongs to the CAT25256 family of serial EEPROMs manufactured by onsemi. It is designed for non-volatile data storage in CMOS technology. The family offers various package options including SOIC, TSSOP, and UDFN, catering to different space and thermal requirements.

Memory IC FAQ

What is the function of the HOLD input pin?

The HOLD input pauses serial communication without retransmitting the sequence. It must be taken low while SCK is low to pause and high to resume.

How does the Identification Page work?

The new product revision includes a 64-byte Identification Page accessible via the IPL bit in the Status Register. It can be permanently write-protected using the LIP bit.
