24LCS52-I/P

Memory IC Overview

The Microchip Technology 24LCS52-I/P is a 2 Kbit (256 x 8) serial Electrically Erasable PROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.2 V to 5.5 V with a maximum clock frequency of 400 kHz. The device supports industrial temperature ranges (-40°C to +85°C) and includes hardware write protection via the WP pin. It offers 1,000,000 erase/write cycles, data retention exceeding 200 years, and low power consumption with typical standby current of 1 µA.

Memory IC Feature Summary

• Hardware write protection for the entire memory array via the dedicated WP pin
• I²C-compatible bidirectional 2-wire serial interface supporting up to 400 kHz clock speeds
• Low-power CMOS technology enabling operation down to 2.2 V with minimal active and standby currents

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Power management circuits needing configuration parameter retention
• Communication and network equipment utilizing serial bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'I/P' corresponds to the Industrial temperature range and PDIP-8 package. Confirm that the operating voltage requirements align with the 2.2 V minimum specification for the 24LCS52 variant. Ensure system design accounts for the hardware write protect pin functionality if permanent data locking is required.

Memory IC Selection Notes

Select this component when a robust, low-pin-count EEPROM with hardware-level write protection is necessary. The 24LCS52 differs from the 24AA52 by supporting higher clock frequencies at voltages above 2.2 V. Consider the PDIP-8 package constraints for through-hole mounting requirements in the target application design.

Memory IC Part Context

This part belongs to the 24XXX52 family of 2 Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features but varies in voltage ranges and clock speed capabilities. The 24LCS52 specifically targets applications requiring reliable data retention and noise immunity in industrial environments.

Memory IC Replacement Considerations

The 24AA52 serves as a functional substitute within the same package, though it has different voltage-dependent clock speed specifications. Verify compatibility regarding the minimum operating voltage and maximum clock frequency before substitution.
