CAT25040VE-GT3

Product Overview

The CAT25040VE-GT3 from onsemi is a non-volatile EEPROM memory integrated circuit with a 4Kbit capacity organized as 512 x 8. It communicates through a serial peripheral interface (SPI) and is supplied in an 8-SOIC surface-mount package. The device operates from a 1.8 V to 5.5 V supply and is specified for an ambient temperature range of -40°C to 125°C. With a 5 ms write cycle time for word or page writes, it supports firmware parameters, calibration values, configuration data, and other small data sets that must remain stored when power is removed.

Key Features

• Non-volatile 4Kbit EEPROM memory with 512 x 8 organization.
• SPI serial interface for embedded controller connections.
• 20 MHz SPI operation.
• 1.8 V to 5.5 V supply range supports low-voltage and 5 V systems.
• 8-SOIC surface-mount package with 3.90 mm body width.
• 5 ms word or page write cycle time.
• -40°C to 125°C ambient operating temperature range.

Applications

• Embedded system parameter storage
• Control-system configuration memory
• Consumer electronics calibration data retention
• Networking equipment identity or settings memory
• Metering and instrumentation small data logging

Design & Procurement Notes

Designers should verify SPI timing and voltage compatibility with the host controller, particularly when operating near the 1.8 V or 5.5 V limits. The 5 ms write cycle affects how frequently parameter updates can be committed and should be considered in firmware update routines. The 512 x 8 organization limits the usable array, so data structures should fit within the available capacity. The 8-SOIC footprint supports surface-mount assembly, and the -40°C to 125°C range should be checked against the final product's ambient environment. For procurement, specify the exact part number CAT25040VE-GT3 to avoid package or interface mismatches.
