CAT25640VI-GT3

Product Overview

The CAT25640VI-GT3 from onsemi is a non-volatile EEPROM memory IC with a 64 Kbit capacity organized as 8K x 8. It uses a serial SPI interface and supports a clock frequency of 20 MHz. The device operates from a 1.8 V to 5.5 V supply and is specified for an ambient temperature range of -40°C to 85°C. The 8K x 8 organization provides 8-bit memory words. The package is a surface-mount 8-SOIC with a 0.154 in, 3.90 mm body width.

Key Features

• Non-volatile EEPROM memory format.
• 64 Kbit EEPROM memory with an 8K x 8 organization.
• Serial SPI memory interface with a 20 MHz clock frequency.
• 5 ms write cycle time for word or page operations.
• 1.8 V to 5.5 V supply voltage range.
• Operating temperature range of -40°C to 85°C.
• Surface-mount 8-SOIC package, 0.154 in, 3.90 mm width.

Applications

• Non-volatile parameter storage in embedded controller assemblies.
• Serial SPI configuration data retention for microcontroller-based designs.
• Small calibration or lookup data storage in sensor modules.
• EEPROM expansion on SPI buses in compact circuit boards.

Design & Procurement Notes

Design teams should verify that the host SPI bus timing is compatible with the 20 MHz clock and that firmware allows for the 5 ms word or page write cycle. The 1.8 V to 5.5 V supply range supports mixed-voltage board planning, while the -40°C to 85°C ambient range defines the operating envelope. The 64 Kbit capacity and 8K x 8 organization guide address and data buffer sizing in firmware. For layout and ordering, use the exact CAT25640VI-GT3 part number and the 8-SOIC, 0.154 in, 3.90 mm surface-mount footprint to maintain package compatibility.
