24LC01BT-E/MS

Memory IC Overview

The Microchip Technology 24LC01BT-E/MS 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 2.5 V to 5.5 V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, ensuring an active read current of 1 mA maximum and standby current of 5 µA maximum at extended temperatures. It offers hardware write protection via the WP pin, page write capability for up to 8 bytes, and data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication protocol with Schmitt trigger inputs for noise suppression
• Includes hardware write-protect functionality that inhibits all memory writes when the WP pin is tied high
• Features an internal address pointer enabling sequential reads and random access operations
• Provides acknowledge polling capability to maximize bus throughput during self-timed write cycles

Memory IC Applications

• Data logging in industrial control systems requiring non-volatile storage
• Configuration parameter storage in consumer electronics operating on single supplies
• Calibration data retention in automotive applications meeting AEC-Q100 standards
• Small data buffer implementation in embedded microcontroller systems

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'MS' denotes the MSOP-8 package. Confirm RoHS compliance status matches project requirements. Ensure the ordering code aligns with the required tape and reel or cut tape packaging format specified by the distributor. Cross-reference the datasheet revision date to ensure compatibility with latest electrical characteristics.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application needs. Choose the Extended temperature grade if operation exceeds standard industrial limits. The MSOP-8 package is suitable for space-constrained surface mount designs. Verify that the system voltage remains above 2.5 V to ensure proper operation, as lower voltages are not supported by this specific variant compared to the 24AA01 series.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA01 and 24FC01 devices but differs in minimum operating voltage and maximum clock frequency specifications. The family utilizes a common pinout and command set, facilitating design flexibility across different voltage and speed requirements within the same product line.

Memory IC Replacement Considerations

The 24LC01B-I/MS serves as the industrial temperature grade equivalent. Other packages such as SOIC-8 (SN), TSSOP-8 (ST), and SC-70-5 (LT) offer physical form factor alternatives with identical electrical performance. Direct substitutes must maintain the 2.5 V minimum supply voltage constraint.
