24C65T/SM

Memory IC Overview

The Microchip Technology 24C65T-I/SM is a 64Kbit (8K x 8) serial EEPROM utilizing an I2C interface. It operates within a supply voltage range of 4.5V to 6V and supports clock frequencies up to 400 kHz with a typical access time of 900 ns. The device features a self-timed write cycle of approximately 5 ms and is housed in an 8-SOIJ surface-mount package. It is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication protocols with noise suppression via Schmitt trigger inputs
• Provides non-volatile data retention ensuring long-term storage reliability
• Includes power-on reset circuitry to prevent invalid memory writes during power transitions

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules operating within standard temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'I' for industrial temperature rating and 'SM' for the SOIJ package when sourcing. Confirm RoHS compliance status as per current manufacturer declarations. Ensure the selected variant matches the required voltage range, as some family members support lower voltages. Check datasheet revisions for any packaging or plating changes documented in Product Change Notices.

Memory IC Selection Notes

Select this component for designs requiring 64Kbit capacity with I2C connectivity. Compare against 24LC65 variants if lower voltage operation below 4.5V is necessary. Consider the 24FC series if higher clock speeds exceeding 400 kHz are required. Verify that the 8-SOIJ footprint fits the PCB layout constraints compared to standard SOIC packages.

Memory IC Part Context

This part belongs to the Microchip 24xx65 family of serial EEPROMs. These devices are designed for applications requiring reliable data storage with simple two-wire interface control. The family offers various voltage and speed options while maintaining compatibility with standard I2C bus protocols across different industrial and commercial environments.

Memory IC Replacement Considerations

Direct substitutes include other 24C65 variants from Microchip such as 24C65/P or 24C65T-I/SN, provided pinouts and electrical characteristics match. Cross-brand replacements require careful verification of voltage levels and timing parameters.
