24LC512T-I/SMG

Memory IC Overview

The Microchip Technology 24LC512T-I/SMG is a 512 Kbit (64K x 8) serial electrically erasable PROM. It operates on a 2-wire I2C interface with a maximum clock frequency of 400 kHz and an access time of 900 ns. The device supports a supply voltage range of 1.7 V to 5.5 V. It is housed in an 8-SOIC package (150 mil wide). The industrial temperature grade covers -40°C to +85°C. Data retention is specified at 200 years.

Memory IC Feature Summary

• Supports high-speed I2C communication up to 400 kHz
• Operates across a broad voltage range from 1.7V to 5.5V
• Provides long-term data retention capabilities

Memory IC Applications

• Industrial control systems requiring non-volatile storage
• Consumer electronics with low power constraints
• Automotive applications within industrial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'SMG' against the official Microchip datasheet to confirm the exact package dimensions and tape-and-reel specifications. Ensure the operating voltage requirements align with the 1.7V to 5.5V range. Confirm that the industrial temperature rating meets the environmental conditions of the target application.

Memory IC Selection Notes

Select this component for designs requiring a compact surface-mount EEPROM with I2C compatibility. The wide voltage range allows flexibility in power supply design. Consider the 8-SOIC package size for PCB layout constraints. Verify that the 400 kHz bus speed is sufficient for the system's data throughput requirements.

Memory IC Part Context

This part belongs to the 24LC512 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other variants like the 24LC512-I/PG and 24LC512T-I/ST, differing primarily in packaging and reel specifications. The family is designed for general-purpose non-volatile memory applications.

Memory IC Replacement Considerations

Check for direct substitutes such as 24LC512T-I/ST or 24LC512T-E/SM if pinout and electrical characteristics match. Verify that any replacement maintains the same I2C interface and voltage range.
