24LC04B/P

Memory IC Overview

The Microchip Technology 24LC04B/P is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and features a Two-Wire Serial Interface compatible with the I²C protocol, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device has a random access time of 900 ns and supports page write operations with a 16-byte buffer. It is housed in an 8-Lead PDIP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional Two-Wire Serial Interface compatible with I²C protocol
• Includes hardware write-protect capability via the WP pin
• Features Schmitt Trigger inputs for noise suppression on SCL and SDA lines
• Provides self-timed erase/write cycles with internal address pointer

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating within specified temperature ranges
• Low-power consumer electronics utilizing I²C communication
• Devices needing hardware-level write protection for critical data

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the 8-Lead PDIP package type. Confirm the industrial temperature grade (-40°C to +85°C) matches the application requirements. Ensure the supply voltage meets the minimum 2.5V threshold for proper operation. Check for RoHS compliance status if required by manufacturing standards.

Memory IC Selection Notes

Select this component when a 4-Kbit EEPROM capacity is required with I²C interface compatibility. Choose the PDIP package for through-hole mounting needs. Consider the 2.5V minimum operating voltage constraint compared to lower-voltage alternatives. Evaluate the 16-byte page write buffer efficiency against byte-write requirements.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA04 and 24FC04 models but differs in minimum operating voltage and maximum clock frequency specifications. The 24LC04B specifically targets applications requiring a 2.5V minimum supply voltage.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04B variants with different packages such as SOIC or MSOP. Cross-reference with 24AA04 or 24FC04 only if voltage and speed requirements align with their respective datasheets.
