24LC01BHT-E/OT

Memory IC Overview

The Microchip Technology 24LC01BHT-E/OT 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 clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, offering a maximum active read current of 1 mA and standby current of 1 μA. It includes hardware write-protect functionality for half the array and provides ESD protection exceeding 4,000V. The component is housed in a 5-lead SOT-23 package and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability allows locking the upper half of the memory array via the WP pin.
• Schmitt trigger inputs on SDA and SCL lines provide noise suppression and spike filtering.
• Output slope control circuitry minimizes ground bounce during switching operations.
• Supports page write operations allowing up to eight bytes of data transfer before an internal write cycle.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control devices needing reliable data retention under varying temperatures
• Consumer electronics utilizing low-voltage power supplies

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the presence of the 'E' designation indicates automotive-grade reliability specifications if operating at elevated temperatures. Ensure the 'T' suffix corresponds to the tape and reel packaging format intended for automated assembly processes.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small capacity data logging. The 5-lead SOT-23 package offers space efficiency compared to standard 8-pin variants. Consider the 400 kHz speed limit for high-throughput applications and ensure the system voltage remains above 2.5V for optimal performance.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1 Kbit serial EEPROMs. It shares architectural similarities with other members like the 24LC01BT but differs in physical footprint and thermal rating. The 'BH' designation typically refers to the broader family including TDFN and MSOP packages, while this specific model targets the SOT-23 form factor.
