24LC1025-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC1025-E/SN16KVAO is a 128K x 8 (1024K bit) Serial Electrically Erasable PROM. It operates within a voltage range of 2.5V to 5.5V and supports I2C™ compatible interfaces with clock frequencies up to 400 kHz. The device features a 128-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead SOIC package and qualified for automotive applications with an operating temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial interface with I2C™ compatibility
• Includes hardware write-protect functionality controlled by the WP pin
• Features output slope control to eliminate ground bounce
• Provides cascading capability for up to four devices on the same bus

Memory IC Applications

• Personal communications systems
• Data acquisition modules
• Automotive electronic subsystems
• Industrial sensor data logging

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and packaging format. Confirm the presence of the 'E' designation indicates automotive qualification (-40°C to +125°C). Ensure the 'SN' suffix corresponds to the 8-lead SOIC package type. Cross-reference the RoHS compliance status with current manufacturer documentation before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires I2C connectivity and robust automotive-grade reliability. The 1Mbit capacity suits applications needing moderate storage density without complex parallel interfaces. Consider the 128-byte page write buffer for efficient data throughput. Verify system voltage levels align with the 2.5V minimum requirement for proper operation.

Memory IC Part Context

This part belongs to the 24XX1025 family, which includes variants like the 24AA1025 and 24FC1025. These devices share similar architectural features but differ in supply voltage ranges and maximum clock speeds. The 24LC1025 specifically targets industrial and automotive environments requiring wider voltage tolerance compared to lower-voltage CMOS alternatives.

Memory IC Replacement Considerations

Direct substitutes include other 24LC1025 variants from Microchip Technology with different temperature grades or packages. Cross-referencing with the 24AA1025 or 24FC1025 may be possible if voltage and speed requirements allow, though electrical characteristics must be carefully matched.
