CAT25010VI-GT3

Product Overview

The CAT25010VI-GT3 from onsemi is a serial EEPROM memory IC intended for embedded systems that need small non-volatile data storage. The device provides 1Kbit of memory organized as 128 x 8 bits and communicates through an SPI interface. It operates from a 1.8V to 5.5V supply and is supplied in an 8-SOIC surface-mount package. The specified operating temperature range is -40°C to 85°C, making it suitable for general electronic assemblies where board-level space is limited and configuration or calibration data must remain available after power removal.

Key Features

• 1Kbit EEPROM memory with a 128 x 8 organization for byte-oriented storage.
• SPI serial interface supports connection to microcontrollers and other digital host devices.
• Supply voltage range of 1.8V to 5.5V allows use with low-voltage and 5V logic systems.
• Specified word or page write cycle time of 5ms.
• 8-SOIC surface-mount package with 3.90mm width for PCB assembly.
• Operating temperature range from -40°C to 85°C.

Applications

• Configuration data storage in embedded controllers and general control boards.
• Calibration parameter retention for measurement instruments and sensor modules.
• Identification or serial-number storage in connected devices and access hardware.
• Small lookup tables or mode settings in battery-powered equipment.

Design & Procurement Notes

Designers should confirm that the host controller supports SPI-compatible signaling and that the selected supply voltage remains within 1.8V to 5.5V. The 128 x 8 organization and 5ms write cycle time are relevant when planning data layout and firmware write timing. The 8-SOIC surface-mount package and -40°C to 85°C operating range should be considered during PCB layout and thermal review. Because the device is a non-volatile EEPROM, it can retain stored bytes without power, but access still depends on correct SPI command sequencing.
