24LCS52-I/ST

Memory IC Overview

The Microchip Technology 24LCS52-I/ST is a 2 Kbit (256 x 8) Electrically Erasable PROM featuring an I²C compatible 2-wire serial interface. It operates within a supply voltage range of 2.2 V to 5.5 V and supports a maximum clock frequency of 400 kHz. The device provides software write protection for the lower 128 bytes and hardware write protection for the entire array via the WP pin. It includes Schmitt trigger inputs, output slope control, and ESD protection exceeding 4,000V. The component is housed in an 8-lead TSSOP package and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer using a standard 2-wire serial bus protocol with up to eight devices on one bus.
• Features self-timed write cycles with a page write buffer capable of storing up to 16 bytes.
• Includes dedicated hardware write protection via the WP pin and permanent software write protection for the lower half of the memory array.

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Consumer electronics utilizing low-power memory
• Smart metering applications

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm that the device meets all applicable RoHS and environmental compliance standards for your region. Ensure that the design accounts for the necessary pull-up resistors on the SDA and SCL lines to maintain signal integrity during operation.

Memory IC Selection Notes

Select this component when a small capacity EEPROM with I²C connectivity is needed. It is suitable for designs requiring robust noise immunity through Schmitt triggers. Consider the hardware write protection capabilities if system security against accidental writes is a priority. Verify that the operating voltage range aligns with the system power supply rails.

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 speeds. The 'I' designation indicates the Industrial temperature rating, while '/ST' specifies the surface-mount TSSOP package configuration.

Memory IC Replacement Considerations

The 24AA52 serves as a functional substitute within the same family, offering similar memory organization and interface protocols. Differences exist primarily in the minimum operating voltage and maximum clock frequency specifications. Verify compatibility regarding voltage thresholds and timing requirements before substitution.
