24C01C/P

Memory IC Overview

The Microchip Technology 24C01C-I/P is a 1K-bit (128 x 8) serial Electrically Erasable PROM featuring an I2C-compatible 2-wire interface. It operates on a single supply voltage ranging from 4.5V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing a maximum read current of 1 mA and standby current of 5 µA. It includes a 16-byte page write buffer and supports up to eight devices on the same bus. The component is housed in an 8-lead PDIP package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard two-wire serial bus protocol compatible with I2C standards.
• Features Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce.
• Includes hardware address selection allowing cascading of up to eight devices for contiguous memory expansion.
• Provides self-timed erase/write cycles with internal timing control upon receipt of a stop condition.

Memory IC Applications

• Data storage for system configuration parameters in embedded controllers
• Logging operational history or calibration constants in industrial instrumentation
• Storing unique identification codes or security keys in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status if lead-free materials are mandatory for the assembly process. Ensure the specific revision level aligns with existing design documentation to avoid potential pinout or electrical characteristic discrepancies during integration.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires simple serial connectivity without complex parallel interfaces. It is suitable for applications needing moderate data retention and endurance within a standard 5V logic environment. Consider alternative packages like SOIC or TSSOP if surface mount technology is preferred over through-hole mounting constraints.

Memory IC Part Context

This part belongs to the 24C01C family of 1K-bit serial EEPROMs manufactured by Microchip Technology. The family shares common electrical characteristics and interface protocols but varies in physical packaging options such as SOIC, TSSOP, DFN, and SOT-23. The 'I' designation indicates the industrial temperature range variant, distinguishing it from commercial or automotive grades within the same product line.

Memory IC Replacement Considerations

Direct replacements include other 24C01C variants with different package suffixes such as 24C01C/SN (SOIC) or 24C01C/ST (TSSOP). Cross-manufacturer equivalents may require verification of voltage tolerances and I2C timing specifications to ensure compatibility with the existing bus architecture.
