24LC08BH-I/P

Memory IC Overview

The Microchip Technology 24LC08BH-I/P is an 8 Kbit Electrically Erasable PROM organized as four blocks of 256 x 8-bit memory. It features a 2-wire serial interface compatible with I²C™, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. It includes hardware write-protect functionality for the upper half of the array (addresses 200h-3FFh) via the WP pin. The component supports page writes up to 16 bytes and offers data retention exceeding 200 years with over one million erase/write cycles endurance.

Memory IC Feature Summary

• Hardware write protection locks the upper half of the memory array when the WP pin is connected to VCC
• Schmitt trigger inputs and filter circuits suppress noise spikes on SDA and SCL lines
• Internal address pointer maintains the last accessed location for sequential read operations
• Acknowledge polling allows the master device to determine when internal write cycles are complete

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Battery-powered devices utilizing low-power CMOS technology
• Automotive electronics operating within extended temperature ranges
• Embedded systems needing secure configuration parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range of -40°C to +85°C. Confirm the '/P' designation indicates the 8-lead PDIP package type. Ensure the 'BH' variant is selected specifically for the half-array write-protect feature rather than standard 24LC08B models. Cross-reference the datasheet revision DS20002084B for accurate electrical characteristics.

Memory IC Selection Notes

Select this component when half-array write protection is required to safeguard critical data in the upper memory region. Choose the 24LC08BH over the 24AA08H if the minimum operating voltage requirement is strictly 2.5V or higher. Consider the PDIP package only for through-hole mounting applications where surface mount options are unsuitable.

Memory IC Part Context

This part belongs to the 24XX08H family of 8 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA08H but differs in minimum operating voltage specifications. The device utilizes a standard I²C protocol for communication, making it compatible with various microcontroller interfaces designed for two-wire bus architectures.
