24FC128-I/SM

Memory IC Overview

The Microchip Technology 24FC128-I/SM is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates with a single supply voltage ranging from 1.7V to 5.5V and supports I2C compatible two-wire serial interfaces at clock frequencies up to 1 MHz. The device features a 64-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock frequencies reaching 1 MHz under specified voltage conditions.
• Includes a 64-byte page write buffer to facilitate efficient data storage operations.
• Provides hardware write protection via the WP pin to secure memory arrays against unauthorized modifications.
• Features Schmitt trigger inputs on SDA and SCL lines to enhance noise immunity.

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature grade. Confirm RoHS compliance status and ensure the component matches the exact datasheet revision required for your design specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when operation below 2.5V is required alongside high-speed 1 MHz I2C performance. Ensure the application environment remains within the specified -40°C to +85°C range. Verify that the system design accommodates the specific address bit limitations inherent to the MSOP package variant.

Memory IC Part Context

This part belongs to the 24XX128 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA128 and 24LC128 but offers distinct electrical characteristics, specifically lower minimum operating voltage and higher maximum clock frequency compared to other variants in the series.

Memory IC Replacement Considerations

Compatible substitutes include the 24AA128 and 24LC128, provided their respective voltage ranges and clock speed limitations align with the system requirements. Verify package compatibility and temperature ratings when substituting.
