24FC1025-I/SN

Memory IC Overview

The Microchip Technology 24FC1025-I/SN is a 1-Mbit (128K x 8) serial EEPROM utilizing an I²C-compatible interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz at voltages above 2.5V, with reduced speeds at lower voltages. The device features a 128-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead SOIC package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz operation across a wide voltage range
• Includes a 128-byte page write buffer for efficient data writing
• Features hardware write protection to secure memory content
• Provides cascading capability for up to four devices on a single bus

Memory IC Applications

• Personal communications systems requiring non-volatile storage
• Data acquisition applications needing reliable parameter retention
• Embedded systems utilizing I²C communication protocols

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage operating range requirements align with the 1.8V minimum specification for the FC series. Ensure the design accommodates the necessary pull-up resistors for the SDA and SCL lines to support the intended clock frequency.

Memory IC Selection Notes

Select this component when a 1-Mbit capacity is required alongside high-speed 1 MHz I²C performance. It is suitable for designs operating between 1.8V and 5.5V where low standby current is beneficial. Consider the 128-byte page buffer size for optimizing write throughput in application software.

Memory IC Part Context

This part belongs to the 24XX1025 family, which includes variants like the 24AA1025 and 24LC1025. The 'FC' designation specifically indicates support for 1 MHz clock speeds at higher voltages, distinguishing it from slower counterparts. All family members share identical pinouts and functional logic but differ in electrical specifications.

Memory IC Replacement Considerations

Direct replacements include other 24FC1025 variants with different packaging or temperature ratings, such as the automotive-grade 24FC1025-E/SN. Cross-family substitutes like the 24LC1025 are functionally compatible but limited to lower clock speeds.
