CAT28LV64GI-25T

Memory IC Overview

The CAT28LV64GI-25T is a 64-kbit CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by onsemi. It features an 8k x 8 organization with parallel interface access. The device operates within a supply voltage range of 3 V to 3.6 V, typically at 3.3 V. Key electrical parameters include a maximum access time of 250 ns and an output enable access time of 100 ns. Active read current is specified at a maximum of 8 mA. The component supports data retention for up to 100 years and functions across an industrial temperature range from -40 °C to +85 °C. It is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package.

Memory IC Feature Summary

• Supports byte-level or page-mode programming operations via standard serial commands.
• Features hardware write protection to prevent accidental modification of stored data.
• Provides high endurance with guaranteed erase/program cycles for long-term reliability.

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Consumer electronics needing configuration data retention
• Embedded systems storing calibration constants

Memory IC Procurement Notes

Verify the specific suffix 'GI' against official datasheets to confirm the PLCC-32 package and industrial temperature grade. Confirm RoHS compliance status as manufacturing processes evolve. Check for End-of-Life notices or Last-Time-Buy dates, as this component family may be discontinued. Ensure pin compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this part when a 64-kbit capacity with parallel interface is required in a surface-mount PLCC package. Compare access times and voltage ranges against alternatives if system timing constraints are tight. Verify that the operating temperature range meets the environmental requirements of the target application. Consider pinout compatibility with legacy designs using similar EEPROM architectures.

Memory IC Part Context

This component belongs to the CAT28LV64 series of low-voltage EEPROMs. It shares architectural similarities with other variants like the CAT28LV64LI and CAT28LV64H13, differing primarily in package type and temperature rating. The series is designed for applications requiring reliable non-volatile memory in compact form factors.

Memory IC Replacement Considerations

CAT28LV64GI-25TE13 is a verified equivalent variant with identical electrical specifications and PLCC-32 packaging, differing only in tape-and-reel shipping format.
