24CS512T-I/SN

Memory IC Overview

The Microchip Technology 24CS512T-I/SN is a 512 Kbit (64K x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) housed in an 8-pin SOIC package. It utilizes the I²C interface with support for high-speed mode operation up to 3.4 MHz and standard mode at 400 kHz. The device features a write access time of 900 ns and operates within a supply voltage range of 1.7 V to 5.5 V. It supports industrial temperature ranges from -40°C to +85°C and includes built-in Error Correction Code (ECC) capabilities.

Memory IC Feature Summary

• Integrated Error Correction Code (ECC) functionality for enhanced data integrity
• Supports high-speed I²C communication modes up to 3.4 MHz
• Wide operating voltage range compatible with various system power supplies

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage
• Consumer electronics utilizing I²C bus architectures
• Data logging applications needing error-corrected memory

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package configuration when sourcing. Confirm that the 'I' grade meets the required industrial temperature specifications for your application environment. Ensure compatibility with the host controller's I²C clock speed requirements, as this device supports high-speed modes distinct from standard EEPROM variants.

Memory IC Selection Notes

Select this component when ECC protection is mandatory for critical data storage. Compare against the 24LC512 series if lower cost is prioritized over error correction, noting the latter lacks ECC. Consider the 24AA512 series if higher speed or different voltage tolerances are needed. Verify pinout compatibility with existing PCB layouts designed for standard 8-pin SOIC packages.

Memory IC Part Context

This part belongs to the 24CSxx family of serial EEPROMs distinguished by their integrated ECC feature set. Unlike the standard 24LCxx or 24AAxx lines, the CS variant provides hardware-level error correction. It shares the same physical footprint and basic I²C protocol as other 512 Kbit devices but offers superior reliability for data-intensive applications.

Memory IC Replacement Considerations

Direct substitutes include other 24CS512 variants with different packages such as 24CS512T-I/MS (MSOP-8) or 24CS512T-I/Q4B (UDFN-8). Cross-family replacements like 24LC512 lack ECC and may not be suitable for error-sensitive designs.
