CAT25040VI-GT3A

Product Overview

CAT25040VI-GT3A is an onsemi EEPROM memory IC that provides 4Kbit of nonvolatile storage in an 8-SOIC surface-mount package. The device uses an SPI interface and is described for 20MHz operation, with a memory organization of 512 x 8. It operates from a 1.8V to 5.5V supply and is specified for an operating temperature range of -40°C to 85°C (TA). The listed write cycle time for word and page operations is 5ms, and .

Key Features

• 4Kbit EEPROM memory organized as 512 x 8
• Nonvolatile memory format retains data without power
• SPI memory interface described for 20MHz operation
• Word and page write cycle time listed as 5ms
• Supply voltage range of 1.8V to 5.5V
• Operating temperature range of -40°C to 85°C (TA)
• Surface-mount 8-SOIC package with 3.90mm body width

Applications

• Storing small configuration parameters that must remain available after power loss
• Retaining calibration coefficients in embedded systems
• Preserving serial-number or asset-tag data in nonvolatile memory

Design & Procurement Notes

Designers should confirm that the host controller supports SPI signaling and can tolerate a 5ms word or page write cycle when updating configuration data. The 1.8V to 5.5V supply range should be checked against the system rail, and the board layout should match the surface-mount 8-SOIC footprint and 3.90mm body width. The -40°C to 85°C TA range should be checked against the final environmental profile. The 512 x 8 organization and 4Kbit capacity should be matched to the required data size, and the supplied Active status should be recorded in design documentation.
