24LC08BH-E/P

Memory IC Overview

The Microchip Technology 24LC08BH-E/P is an 8 Kbit Electrically Erasable PROM organized as four blocks of 256 x 8-bit memory. It features a 2-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz for VCC between 2.5V and 5.5V. The device operates on a single supply voltage ranging from 2.5V to 5.5V, with a maximum active current of 1 mA and standby current of 1 µA. It supports page writes of up to 16 bytes and includes hardware write protection for the upper half of the array (addresses 200h-3FFh). The component is rated for an industrial temperature range of -40°C to +125°C and is housed in an 8-pin PDIP package.

Memory IC Feature Summary

• Hardware write protection locks the upper half of the memory array when the WP pin is tied high.
• Schmitt trigger inputs and filter circuits suppress noise spikes on the SCL and SDA lines.
• Output slope control minimizes ground bounce during switching operations.
• Self-timed erase/write cycles allow immediate bus release upon completion.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics operating under extended temperature conditions
• Embedded devices needing secure configuration parameter retention

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C) rather than the Industrial grade. Confirm the 'P' suffix indicates the 8-lead PDIP package type. Ensure the specific revision matches the required datasheet version DS20002084B. Cross-reference the manufacturer part number against official Microchip databases to validate authenticity before procurement.

Memory IC Selection Notes

Select this component when an I2C EEPROM requires operation within the automotive temperature range while maintaining compatibility with standard 2.5V to 5.5V logic levels. The 8Kbit capacity suits applications storing moderate amounts of system configuration or calibration data. The PDIP package facilitates prototyping and through-hole assembly processes where surface-mount options are unsuitable.

Memory IC Part Context

This device belongs to the 24AA08H/24LC08BH family of 8Kbit serial EEPROMs. The 'LC' designation indicates a minimum operating voltage of 2.5V, distinguishing it from the 'AA' variant which supports lower voltages down to 1.7V. The 'BH' suffix denotes the inclusion of half-array write protection capabilities not present in earlier generations.

Memory IC Replacement Considerations

The 24LC08B-I/P serves as a functional substitute if the industrial temperature range (-40°C to +85°C) suffices for the application. Verify that the replacement part maintains the same PDIP package dimensions and pinout configuration to ensure mechanical compatibility.
