24LC08BH-E/MS

Memory IC Overview

The Microchip Technology 24LC08BH-E/MS 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 within a supply voltage range of 2.5V to 5.5V and supports industrial temperature grades from -40°C to +125°C. Key electrical characteristics include a standby current of up to 1 µA, active read current of 1 mA, and write cycle time of 5 ms.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array (addresses 200h-3FFh) via the WP pin
• 16-byte page write buffer allowing efficient sequential data storage
• Schmitt trigger inputs on SCL and SDA lines for enhanced noise suppression
• Output slope control mechanism designed to eliminate ground bounce during switching

Memory IC Applications

• Industrial control systems requiring non-volatile data retention
• Automotive electronics operating in high-temperature environments
• Consumer devices needing low-power configuration storage
• Embedded systems utilizing I2C bus communication protocols

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended automotive temperature range (-40°C to +125°C) rather than standard industrial limits. Confirm the '/MS' designation corresponds to the MSOP package type. Ensure compatibility with system voltage levels, noting the minimum operational threshold is 2.5V. Check for RoHS compliance status if required by manufacturing standards.

Memory IC Selection Notes

Select this component when an 8 Kbit capacity is required with hardware-level write protection for critical data segments. The MSOP package is suitable for space-constrained surface-mount designs. Consider the 400 kHz speed limit at higher voltages versus the 100 kHz limit below 2.5V. Verify that the application does not require the lower 1.7V operation available in the 24AA08H variant.

Memory IC Part Context

This part belongs to the 24XX08H family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08H but differs in minimum operating voltage specifications. The device utilizes a standard 8-pin MSOP footprint and integrates internal address pointers for random and sequential access operations across its four memory blocks.
