24LC08B-E/P

Memory IC Overview

The Microchip Technology 24LC08B-E/P is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols, supporting a maximum clock frequency of 400 kHz at supply voltages between 2.5V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and is housed in an 8-lead PDIP package.

Memory IC Feature Summary

• Supports hardware write protection via the WP pin to inhibit write operations when tied to VCC
• Includes Schmitt trigger inputs and filter circuits on SDA and SCL pins for noise suppression
• Features a 16-byte page write buffer to optimize data transfer efficiency
• Provides output slope control to eliminate ground bounce during switching

Memory IC Applications

• Industrial control systems requiring extended temperature operation
• Battery-powered devices utilizing low standby current modes
• Automotive electronics certified under AEC-Q100 standards
• Data logging applications needing high endurance cycles

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'P' denotes the 8-lead PDIP package. Confirm the voltage range specification matches the 2.5V minimum requirement for the 24LC08B series, distinct from lower-voltage variants like the 24AA08. Ensure compatibility with I²C bus pull-up resistor values appropriate for the 400 kHz operating speed.

Memory IC Selection Notes

Select this component when application environments demand operation up to +125°C ambient temperature. The 24LC08B requires a minimum supply voltage of 2.5V, which differs from the 1.7V capability of the 24AA08. Choose the PDIP package for through-hole mounting requirements or prototyping breadboards where surface-mount packages are unsuitable.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes the 24AA08 and 24FC08, which share similar interfaces but differ in voltage ranges and clock speeds. The 24LC08B specifically targets industrial and automotive sectors requiring robust thermal performance and standard I²C compatibility.

Memory IC Replacement Considerations

The 24LC08B-I/P serves as a direct functional substitute if the industrial temperature range (-40°C to +85°C) suffices for the application. Other 24LC08B variants with different packaging suffixes may replace this unit provided the physical footprint allows.
