CAT25320HU3IGT3C

Product Overview

The CAT25320HU3IGT3C from onsemi is a non-volatile EEPROM memory IC with a 32Kbit capacity organized as 4K x 8. It communicates over an SPI interface and supports a clock frequency of 10 MHz. The device operates from a 1.8V to 5.5V supply and is specified for an ambient temperature range of -40°C to 85°C. It is supplied in an 8-UDFN (2x3) surface-mount package, listed as an 8-UFDFN exposed-pad case. The lifecycle status is Active.

Key Features

• 32Kbit non-volatile EEPROM memory organized as 4K x 8.
• SPI serial interface with a 10 MHz clock frequency.
• 1.8V to 5.5V supply voltage range.
• 5ms write cycle time for word and page writes.
• -40°C to 85°C operating temperature range.
• Surface-mount 8-UDFN (2x3) package with 8-UFDFN exposed pad.

Applications

• Storing non-volatile configuration settings in embedded controllers that use SPI peripherals.
• Retaining calibration constants or user parameters in measurement and instrumentation equipment.
• Recording small serial-number or asset-identity data in embedded devices.
• Preserving operational parameters in instruments where memory retention during power-off is required.

Design & Procurement Notes

Designers selecting the CAT25320HU3IGT3C from onsemi should verify that their host controller provides SPI timing compatible with a 10 MHz clock and that the system supply remains within 1.8V to 5.5V across operating conditions. The 5ms word/page write cycle time should be accounted for in firmware that performs frequent updates, and the -40°C to 85°C ambient range should be checked against the final product environment. The 8-UDFN (2x3) surface-mount package with exposed pad requires footprint and soldering compatibility with the chosen assembly process. Because the supplied lifecycle status is Active, it can be considered for current designs, while procurement should confirm the exact package variant and lifecycle status before finalizing the design.
