CAT25320VP2IGTKK

Product Overview

The CAT25320VP2IGTKK from onsemi is a 32 Kbit non-volatile EEPROM memory IC organized as 4K x 8. It communicates over a serial peripheral interface (SPI) with a 10 MHz clock frequency and operates from a 1.8 V to 5.5 V supply. The device uses an 8-TDFN (2x3) surface-mount package with an exposed pad, with an 8-WFDFN Exposed Pad case. Its specified operating temperature range is -40°C to 85°C (TA), and the word or page write cycle time is 5 ms.

Key Features

• 32 Kbit EEPROM memory with a 4K x 8 organization.

• SPI memory interface with a 10 MHz clock frequency.
• 1.8 V to 5.5 V supply voltage range.
• 5 ms word or page write cycle time.
• 8-TDFN (2x3) surface-mount package with exposed pad.
• Operating temperature range of -40°C to 85°C (TA).

Applications

• Embedded controller configuration data storage
• Sensor calibration data storage
• Device parameter storage in SPI-connected systems
• Serial peripheral interface-based memory expansion in controller designs

Design & Procurement Notes

When integrating the CAT25320VP2IGTKK, verify that the host controller supports SPI operation at the specified 10 MHz clock frequency and that the system supply remains within the 1.8 V to 5.5 V range. The 8-TDFN (2x3) exposed-pad package requires surface-mount assembly and appropriate pad, stencil, and reflow considerations for the exposed pad. Designers should account for the 5 ms word or page write cycle time in firmware timing and system initialization, and confirm that the -40°C to 85°C (TA) operating range is suitable for the intended environment.
