CAT25010HU4I-GT3

Product Overview

The onsemi CAT25010HU4I-GT3 is a 1 Kbit EEPROM memory IC intended for non-volatile data storage in embedded systems. It uses an SPI interface specified at 10 MHz. The device is supplied in an 8-UDFN-EP (2x3) surface-mount package with an exposed pad. It operates from a 1.8 V to 5.5 V supply and is specified for an ambient temperature range of -40°C to 85°C. The memory is organized as 128 x 8 bits, and the word/page write cycle time is 5 ms.

Key Features

• 1 Kbit non-volatile EEPROM memory organized as 128 x 8 bits.
• SPI serial memory interface specified at 10 MHz.
• Supply voltage range of 1.8 V to 5.5 V.
• Word/page write cycle time of 5 ms.
• Surface-mount 8-UFDFN exposed-pad package with a 2x3 form factor.
• Operating temperature range of -40°C to 85°C TA.

Applications

• Embedded controllers that retain small configuration settings after power removal.
• Sensor modules that store calibration coefficients or identification data.
• Equipment boards that require compact non-volatile storage for serial numbers or asset tags.
• Control assemblies using an SPI host interface to update limited parameter sets.

Design & Procurement Notes

For board design, account for the 8-UDFN-EP (2x3) surface-mount package and exposed pad when defining the footprint and assembly process. The 1.8 V to 5.5 V supply range supports integration into low-voltage or 5 V SPI systems, but host interface levels and timing should be checked against the selected controller. The 1 Kbit capacity and 128 x 8 organization are suited to small parameter sets rather than large data sets. The 5 ms word/page write cycle time should be considered in firmware to avoid excessive write attempts or to schedule updates during low-activity periods. The -40°C to 85°C TA range guides thermal placement and operating margin.
