25AA080D-I/SN

Memory IC Overview

The Microchip Technology 25AA080D-I/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization and a 32-byte page size. It operates via a SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 1.8V to 5.5V and functions within an industrial temperature range of -40°C to +85°C. It is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports block write protection for none, 1/4, 1/2, or all array segments
• Includes built-in power-on/off data protection circuitry
• Features a hold pin to pause serial communication without resetting the sequence

Memory IC Applications

• Microcontroller system data storage
• Industrial control parameter logging
• Configuration memory for embedded devices

Memory IC Procurement Notes

Verify the specific suffix 'I/SN' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 8-lead SOIC package type. Confirm that the 'D' designation indicates the required 32-byte page size for your application architecture. Ensure compatibility with the 1.8V minimum operating voltage if using low-power logic levels.

Memory IC Selection Notes

Select this component when a 32-byte page buffer is preferred over the 16-byte alternative found in the 'C' version devices. The 'AA' prefix indicates support for 1.8V operation, making it suitable for low-voltage systems where the 'LC' series would not function. Verify that the host microcontroller supports the standard SPI Mode 0,0 or Mode 1,1 timing requirements.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8K SPI EEPROMs. The 'D' variant specifically provides a 32-byte page size, distinguishing it from the 16-byte 'C' version. The 'SN' suffix denotes the 8-lead Small Outline Integrated Circuit (SOIC) physical package format used for surface-mount assembly.
