24AA02-I/P

Memory IC Overview

The Microchip Technology 24AA02-I/P is a 2-Kbit (256 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device supports an 8-byte page write buffer and includes hardware write protection via the WP pin. It offers over one million erase/write cycles, data retention exceeding 200 years, and operates within an industrial temperature range of -40°C to +85°C.

• Configuration parameter storage in consumer electronics
• Device identification and calibration data logging
• Industrial control system non-volatile memory backup

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status as specified in the datasheet. Ensure the specific part number corresponds to the intended voltage and speed requirements for the target application design.

Memory IC Selection Notes

Select this component when a 2-Kbit EEPROM with I²C interface is required. The 'I' suffix indicates the industrial temperature range (-40°C to +85°C). The '/P' suffix specifies the 8-Lead PDIP package. Verify compatibility with the system's operating voltage range of 1.7V to 5.5V.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants like 24LC02B and 24FC02, which differ primarily in minimum operating voltage and maximum clock frequency specifications while sharing similar interface and memory organization characteristics.

Memory IC Replacement Considerations

Compatible substitutes include other 24AA02 variants with different packages or temperature grades, such as 24AA02-I/ST or 24AA02-I/SN. Cross-family replacements like 24LC02B are possible but require verification of the minimum operating voltage requirement.
