24LC01BT-E/MNY

Memory IC Overview

The Microchip Technology 24LC01BT-E/MNY is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-Wire I2C compatible serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, ensuring an active read current of up to 3 mA and standby current of up to 5 µA at extended temperatures. It offers hardware write protection via the WP pin, an 8-byte page write buffer, and data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with Schmitt trigger inputs for noise suppression
• Includes hardware write-protect capability to inhibit memory writes when the WP pin is tied high
• Features an 8-byte page write buffer to optimize data transfer efficiency
• Provides robust ESD protection exceeding 4,000V on all pins

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in consumer electronics
• Asset tracking identification modules

Memory IC Procurement Notes

Verify that the ordering suffix correctly identifies the MNY package variant and Extended temperature grade. Confirm RoHS compliance status as required by specific project regulations. Ensure the procurement channel provides valid traceability documentation. Cross-reference the manufacturer part number against official distributor catalogs to prevent substitution errors during sourcing.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage I2C applications. The Extended temperature rating makes it suitable for harsh environments where standard Industrial grades are insufficient. Consider the 8-byte page buffer for write-heavy workloads to reduce internal programming time overhead compared to byte-write operations.

Memory IC Part Context

This EEPROM belongs to the 24LC01B family, designed for general-purpose non-volatile data storage. It shares architectural similarities with the 24AA01 and 24FC01 devices but is distinguished by its specific 2.5V minimum operating voltage requirement. The MNY suffix denotes the 8-lead TDFN package format, providing a small footprint for space-constrained PCB designs.

Memory IC Replacement Considerations

Direct substitutes include other 24LC01B variants in different packages such as SOIC or TSSOP. For lower voltage requirements, the 24AA01 series may be considered if the system voltage drops below 2.5V. Higher speed options like the 24FC01 are available for 1 MHz operation.
