25AA080C-I/MS

Memory IC Overview

The Microchip Technology 25AA080C-I/MS is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus interface with a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges from -40°C to +85°C. It incorporates a 16-byte page write buffer, self-timed erase/write cycles, and block write protection capabilities.

Memory IC Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz for efficient data transfer.
• Includes hardware write-protect functionality via the WP pin and software-based block protection for array security.
• Features low-power CMOS technology with standby current as low as 1 µA at maximum voltage.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded microcontroller applications needing configuration parameter retention
• Automotive electronics operating in harsh thermal environments

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'MS' denotes the MSOP package. Confirm the 'C' variant indicates the 16-byte page size rather than the 32-byte 'D' version. Ensure compatibility with the target system's SPI voltage levels and check for any recent Product Change Notifications affecting the manufacturing process or materials.

Memory IC Selection Notes

Select this component when a low-voltage operation down to 1.8 V is required, distinguishing it from the 2.5 V minimum 25LC080 series. Choose the MSOP package for space-constrained surface-mount designs. Consider the 16-byte page size limitation for write operations compared to larger page alternatives if frequent small writes are anticipated.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8 Kbit Serial EEPROMs. It shares architectural similarities with the 25LC080C but differs in its lower minimum operating voltage of 1.8 V. The device is designed for direct interfacing with popular microcontroller families via the SPI protocol.

Memory IC Replacement Considerations

The 25AA080C-I/SN serves as a pin-compatible replacement offering the same electrical characteristics in a SOIC-8 package. For through-hole requirements, the 25AA080C-I/P provides identical functionality in a PDIP-8 package.
