24C65-I/SM

Memory IC Overview

The Microchip Technology 24C65-I/SM is a 64 Kbit (8K x 8) serial EEPROM utilizing an I2C interface. It operates within a voltage range of 4.5V to 6V and supports clock frequencies up to 400 kHz. The device features a write cycle time of 900 ns and is housed in an 8-SOIJ package with a width of 5.30 mm. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication protocols with standard and fast mode capabilities.
• Provides non-volatile data storage with robust endurance characteristics for frequent write operations.
• Includes hardware write protection mechanisms to prevent accidental data modification.

Memory IC Applications

• Industrial control systems requiring reliable parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules operating under strict environmental conditions

Memory IC Procurement Notes

Verify the specific suffix against official datasheets to confirm package dimensions and lead-free status. Ensure the supply voltage matches the 4.5V to 6V requirement, as this variant differs from lower-voltage counterparts. Confirm compatibility with existing I2C bus addressing schemes before integration into production designs.

Memory IC Selection Notes

Select this component when a 6V operating voltage is required rather than the 1.7V or 2.5V variants found in the 24LC or 24FC series. The 8-SOIJ package offers a compact footprint suitable for space-constrained printed circuit board layouts. Verify that the system's I2C pull-up resistors are correctly sized for the 400 kHz maximum clock frequency specification.

Memory IC Part Context

This part belongs to the Microchip 24xx65 family of serial EEPROMs, which provides 64 Kbit of memory organized as 8K words by 8 bits. The family shares common interface protocols but varies in operating voltage and package options. The 'I' designation indicates the industrial temperature grade, ensuring performance stability in demanding environments compared to commercial grades.

Memory IC Replacement Considerations

The 24C65T-I/SM is a verified substitute offering identical electrical specifications and pinout compatibility. Users should verify that the tape-and-reel packaging of the T-variant aligns with their automated assembly requirements without affecting functional performance.
