24LC512-E/MS

Memory IC Overview

The Microchip Technology 24LC512-E/MS is a 512Kbit (64K x 8) CMOS Serial I²C EEPROM. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features a write cycle time of 5ms per word or page, with an access time of 900 ns. It is housed in an 8-MSOP package and functions across a temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed I²C communication with standard and fast mode compatibility.
• Provides non-volatile data retention for critical system parameters and logs.
• Enables multiple devices on a single bus via hardware address pins.

Memory IC Applications

• Industrial sensor data logging
• Embedded system configuration storage
• Calibration data preservation

Memory IC Procurement Notes

Verify the specific suffix 'MS' corresponds to the 8-pin MSOP package when sourcing. Confirm that the '-E' designation indicates compliance with extended industrial temperature specifications. Ensure the supplier provides official datasheets to validate electrical characteristics against the manufacturer's documentation before integration.

Memory IC Selection Notes

Select this component for applications requiring moderate storage density with low pin count. The I²C interface simplifies PCB routing compared to parallel memories. Consider the 5ms write cycle duration when designing software timing loops to ensure data integrity during write operations.

Memory IC Part Context

This part belongs to the 24LC512 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other variants like the 24LC512-E/SN but differs in physical packaging. The series is widely used in embedded systems where reliable, byte-level non-volatile storage is required.

Memory IC Replacement Considerations

Direct substitutes include other 24LC512 variants from Microchip, such as the 24LC512-E/SN or 24LC512T-E/SM, provided the package type matches the design constraints. Cross-manufacturer equivalents may require verification of I²C address bits and voltage tolerances.
