CAT25010YI-G

Product Overview

The CAT25010YI-G from onsemi is a 1Kbit nonvolatile EEPROM memory IC with an SPI interface in an 8-TSSOP surface-mount package. The device is organized as 128 x 8 and operates from a 1.8V to 5.5V supply over a temperature range of -40°C to 85°C. Its small memory capacity and serial interface make it suitable for storing limited configuration data, calibration values, or identifiers in compact embedded designs.

Key Features

• 1Kbit EEPROM memory with a 128 x 8 organization.
• Nonvolatile memory format retains stored data when power is removed.
• SPI serial interface for connection to a host controller.
• 5ms write cycle time for word or page writes.
• 1.8V to 5.5V supply voltage range.
• Operating temperature range of -40°C to 85°C.
• 8-TSSOP surface-mount package, 0.173 inch / 4.40mm width.

Applications

• Embedded systems that need to preserve small configuration parameters after power removal.
• Sensor and measurement modules that retain calibration constants or short data tables.
• Embedded products that store serial numbers, asset identifiers, or other small nonvolatile records.

Design & Procurement Notes

Design considerations include the 1Kbit capacity, which is organized as 128 x 8, so data structures should be planned around that organization. The SPI interface requires connection to a host controller, while the 5ms word or page write cycle time affects write scheduling. The 1.8V to 5.5V supply range and -40°C to 85°C operating temperature support a range of embedded board environments. Layout should account for the 8-TSSOP surface-mount package, including the 4.40mm body width.
