24AA1026-I/SN

Memory IC Overview

The Microchip Technology 24AA1026-I/SN 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 400 kHz. The device utilizes an I2C compatible 2-wire interface and features a 128-byte page write buffer. It is housed in an 8-lead SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports both byte and page write operations with up to 128 bytes of data buffering
• Features hardware write protection via the WP pin to inhibit array writes
• Includes Schmitt trigger inputs for enhanced noise suppression
• Capable of cascading up to four devices on the same data bus

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Advanced low-power electronic designs

Memory IC Procurement Notes

Verify that the ordering suffix matches the required specifications, specifically confirming the 'I' designation for the industrial temperature range and 'SN' for the SOIC package type. Ensure the component meets RoHS compliance requirements for your specific manufacturing process. Cross-reference the manufacturer part number against official datasheets to confirm electrical characteristics before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 1 Mbit non-volatile memory solution is required with a broad operating voltage range starting at 1.7V. It is suitable for designs needing I2C compatibility and hardware-level write protection. Consider the 128-byte page write capability for efficient data handling. Verify that the 400 kHz clock speed aligns with system timing constraints and that the SOIC package fits the board layout.

Memory IC Part Context

This device belongs to the 24XX1026 family of serial EEPROMs from Microchip Technology. The family includes variants like the 24LC1026 and 24FC1026, which share similar architectures but differ in voltage ranges and clock speeds. The 24AA1026 variant is specifically optimized for operation down to 1.7V, distinguishing it from other family members.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC1026 and 24FC1026. Note that these alternatives may have different minimum voltage requirements or maximum clock frequencies compared to the 24AA1026. Verify electrical specifications carefully before substitution.
