24LC01BHT-E/LT

Memory IC Overview

The Microchip Technology 24LC01BHT-E/LT is a 1 Kbit (128 x 8) serial Electrically Erasable PROM featuring an I2C-compatible 2-wire 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 automotive-grade components with an extended temperature range from -40°C to +125°C. Key electrical parameters include a typical write cycle time of 3 ms, a maximum active read current of 1 mA, and standby current of 1 μA. It offers over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Schmitt trigger inputs on SDA and SCL pins to suppress noise spikes
• Output slope control designed to eliminate ground bounce during switching
• Page write functionality allowing up to eight bytes of data transfer in a single operation

Memory IC Applications

• Automotive electronic systems requiring high-temperature reliability
• Industrial controllers needing non-volatile storage for configuration data
• Consumer devices utilizing low-power EEPROM for parameter retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the design accounts for the specific voltage requirements associated with the 'E' automotive grade designation. Cross-reference the datasheet revision date to validate all electrical characteristics before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when an I2C interface is required alongside automotive-grade temperature stability. The 'E' suffix indicates suitability for environments operating up to 125°C. Consider the SC-70 package size if board space is limited. Verify that the system voltage remains above 2.5V to ensure proper operation of the 24LC01BH series variants.

Memory IC Part Context

This part belongs to the 24LC01BH family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA01H but differs in minimum operating voltage. The family supports multiple package options including TSSOP, SOIC, and SC-70. It is designed for applications requiring reliable data storage with hardware write protection features.
