24FC1026-I/P

Memory IC Overview

The Microchip Technology 24FC1026-I/P is a 128K x 8 (1024 Kbit) serial electrically erasable PROM. It operates within a voltage range of 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz at VCC ≥ 2.5V, with 400 kHz operation at lower voltages. The device utilizes an I²C compatible 2-wire interface and features a 128-byte page write buffer. It is housed in an 8-lead PDIP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for efficient data transfer
• Includes hardware write-protect functionality via the WP pin
• Features Schmitt trigger inputs for enhanced noise suppression
• Capable of cascading up to four devices on a single bus

Memory IC Applications

• Personal communications systems
• Data acquisition modules
• Low-power embedded memory storage
• Industrial control interfaces

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage operating range aligns with system requirements, as the FC variant supports 1.7V minimum. Ensure compatibility with the host controller's I2C speed capabilities before finalizing procurement.

Memory IC Selection Notes

Select this component when high-speed 1 MHz communication is required alongside low-voltage operation. The Industrial temperature grade suits general-purpose applications. Consider the PDIP package only if through-hole mounting is necessary for mechanical stability or prototyping constraints.

Memory IC Part Context

This part belongs to the 24XX1026 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA1026 and 24LC1026 but distinguishes itself by supporting higher clock frequencies. The 'I' designation indicates the industrial temperature rating, while 'P' specifies the plastic dual in-line package.

Memory IC Replacement Considerations

The 24AA1026-I/P and 24LC1026-I/P are functionally similar within the same datasheet family. Note that these alternatives operate at a maximum of 400 kHz, which is slower than the 1 MHz capability of the 24FC1026.
