24FC1026T-I/SN

Memory IC Overview

The Microchip Technology 24FC1026T-I/SN is a 128K x 8 (1024 Kbit) serial electrically erasable PROM. It operates across a voltage range of 1.7V to 5.5V with a maximum clock frequency of 1 MHz at VCC ≥ 2.5V. The device features a 128-byte page write buffer, Schmitt trigger inputs for noise suppression, and hardware write protection via the WP pin. It supports I²C compatible 2-wire serial interfaces and includes ESD protection exceeding 4000V.

Memory IC Feature Summary

• Low-power CMOS technology with standby current of 5 µA maximum
• Hardware write-protect capability controlled by the WP pin
• Schmitt trigger inputs provide improved noise spike suppression
• Output slope control designed to eliminate ground bounce

Memory IC Applications

• Personal communications systems requiring low power consumption
• Data acquisition applications needing non-volatile storage
• Embedded systems utilizing I²C bus architectures
• Devices requiring hardware-level data protection

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape and reel packaging as specified in the datasheet. Confirm the 'I' suffix indicates the industrial temperature range of -40°C to +85°C. Ensure the 'SN' designation matches the 8-lead SOIC package dimensions. Cross-reference the specific revision level against the manufacturer's latest documentation to confirm compatibility.

Memory IC Selection Notes

Select this component when high-speed 1 MHz operation is required within the 2.5V to 5.5V supply range. It serves as a direct functional alternative to the 24LC1026 but offers faster clock speeds at higher voltages. Consider the 128-byte page write buffer for efficient bulk data transfers. Verify that the system design accommodates the specific electrical characteristics defined for the FC series devices.

Memory IC Part Context

This part belongs to the 24XX1026 family, which includes the 24AA1026, 24LC1026, and 24FC1026 variants. These devices share identical memory architecture and pinouts but differ in operating voltage ranges and maximum clock frequencies. The 24FC1026 variant specifically enables 1 MHz operation at VCC levels above 2.5V, distinguishing it from the standard 400 kHz counterparts.

Memory IC Replacement Considerations

The 24LC1026T-I/SN is a verified substitute offering identical functionality with a 400 kHz maximum clock speed. The 24AA1026T-I/SN provides equivalent performance with a wider 1.7V minimum voltage support.
