24LC1026-I/P

Memory IC Overview

The Microchip Technology 24LC1026-I/P is a 128K x 8 (1024 Kbit) serial electrically erasable PROM. It operates within a voltage range of 2.5V to 5.5V and supports I2C compatible 2-wire serial interfaces with maximum clock frequencies of 100 kHz or 400 kHz depending on supply voltage. The device features a 128-byte page write buffer, hardware write protection, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead PDIP package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports byte and page write operations with up to 128 bytes of data buffering
• Includes hardware write-protect functionality via the WP pin
• Features Schmitt trigger inputs for enhanced noise suppression
• Allows cascading of up to four devices on the same data bus

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Low-power embedded memory storage

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 'I' suffix denotes industrial specifications. Ensure compatibility with the host controller's I2C interface timing constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a 1 Mbit non-volatile memory solution is required for industrial environments. It is suitable for designs needing hardware write protection and low standby current. Consider the PDIP package for through-hole mounting needs. Verify that the system voltage remains above 2.5V to ensure full 400 kHz clock speed operation.

Memory IC Part Context

This part belongs to the 24XX1026 family, which includes variants like the 24AA1026 and 24FC1026. These devices share identical functional architectures but differ in voltage ranges and clock speeds. The 24LC1026 specifically targets the 2.5V to 5.5V operational window, distinguishing it from lower voltage counterparts.

Memory IC Replacement Considerations

The 24AA1026 serves as a direct functional substitute with a wider voltage range starting at 1.7V. Other family members include the 24FC1026, which offers higher clock speeds. Ensure any replacement maintains the 8-pin PDIP package and industrial temperature rating.
