24FC02-I/P

Memory IC Overview

The Microchip Technology 24FC02-I/P is a 2-Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible two-wire interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz across the full voltage range. The device features a maximum access time of 450 ns and a page write buffer for 8 bytes, with a typical write cycle time of 5 ms. It is housed in an 8-lead PDIP package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication at voltages down to 1.7V
• Includes hardware write protection via the WP pin to inhibit memory writes
• Features Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial sensor networks
• Configuration storage for embedded microcontrollers
• Calibration data retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP package type. Ensure the specific revision matches the required datasheet version DS20001709N for accurate electrical timing parameters.

Memory IC Selection Notes

Select this component when a 1 MHz I²C bus speed is required at low supply voltages starting from 1.7V. It is suitable for applications needing hardware write protection and robust noise immunity through Schmitt triggers. Compare against the 24LC02B if only 400 kHz speed is needed or if the minimum voltage must be higher.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs. It shares the same physical footprint and basic protocol as the 24AA02 and 24LC02B but offers superior clock frequency performance. The family provides non-volatile storage with high endurance and long data retention capabilities.

Memory IC Replacement Considerations

The 24AA02 and 24LC02B are functionally compatible regarding pinout and protocol. However, they are limited to 400 kHz operation, whereas the 24FC02 supports 1 MHz. Verify voltage compatibility, as the 24LC02B requires a minimum of 2.5V.
