24LC01BH-I/P

Memory IC Overview

The Microchip Technology 24LC01BH-I/P 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 clock frequencies up to 400 kHz. The device includes hardware write protection for the upper half of the memory array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce. It is housed in an 8-lead PDIP package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Schmitt trigger inputs on SDA and SCL lines provide enhanced noise suppression for reliable data transmission.
• Output slope control circuitry minimizes ground bounce effects during high-speed switching operations.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial devices needing secure data retention with half-array write protection
• Low-power applications utilizing I²C communication protocols

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage specifications align with the system design, as this variant requires a minimum of 2.5V. Ensure compatibility with the host controller's I²C bus timing requirements before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM with dedicated hardware write protection for half the memory space is required. It is suitable for designs operating between 2.5V and 5.5V where industrial temperature stability is necessary. Consider alternative variants if lower voltage operation below 2.5V or different package styles are needed.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1 Kbit serial EEPROMs. It shares architectural similarities with other members of the series but is distinguished by its specific voltage range and package configuration. The 'I' suffix indicates the industrial temperature rating, while '/P' denotes the PDIP package style.

Memory IC Replacement Considerations

Direct replacements include other 24LC01B variants with identical pinouts and functionality, such as the 24LC01B-I/P. Verify that any substitute maintains the same voltage range and write protection features to ensure circuit compatibility.
