CAT25320VI-GT3

Product Overview

The onsemi CAT25320VI-GT3 is a 32Kbit nonvolatile EEPROM memory IC organized as 4K x 8 and accessed through an SPI interface with a 10 MHz clock frequency. It operates from a 1.8V to 5.5V supply. The device uses an 8-SOIC surface-mount package with a 3.90mm body width, for embedded designs that require serial configuration data retention.

Key Features

• 32Kbit nonvolatile EEPROM memory with 4K x 8 organization.
• SPI serial interface with a 10 MHz clock frequency.
• 1.8V to 5.5V supply voltage range.
• 5 ms word or page write cycle time.
• Operating temperature range from -40°C to 85°C.
• Surface-mount 8-SOIC package with 0.154 inch, 3.90 mm width.

Applications

• Nonvolatile storage of configuration parameters in embedded controller systems.
• Retention of calibration values or operating settings in measurement and control equipment.
• Serial data storage for user-set options in electronic assemblies.

Design & Procurement Notes

When selecting this EEPROM for a board, verify SPI timing compatibility with the 10 MHz clock frequency and confirm that the supply rail remains within 1.8V to 5.5V. The 5 ms word or page write cycle time should be considered when scheduling updates, especially in systems that write frequently or require deterministic response times. The 8-SOIC footprint and surface-mount termination define the board layout, while the -40°C to 85°C operating range helps set thermal margins for the target environment. Designers should map the 4K x 8 memory organization to their data layout and reserve appropriate address space for configuration, calibration, or identification fields.
