AT25080N-10SC-1.8

Memory IC Overview

The AT25080N-10SC-1.8 is an 8K-bit (1024 x 8) SPI serial EEPROM in an 8-lead SOIC package. It operates at a maximum clock frequency of 3 MHz with a supply voltage range of 1.8V to 3.6V. The device supports page writes up to 32 bytes and features self-timed write cycles with a maximum duration of 20 ms. It offers one million write cycle endurance and 100-year data retention.

Memory IC Feature Summary

• Supports SPI Modes 0 and 3 for synchronous serial communication
• Provides hardware and software block write protection for the memory array
• Includes a HOLD pin to pause serial communication without resetting the sequence

Memory IC Applications

• Industrial and commercial applications requiring low-power operation
• Microcontroller systems needing non-volatile data storage
• Embedded solutions where space-saving packages are essential

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage range and temperature grade. Confirm the package type corresponds to the design footprint. Check RoHS compliance status if required by regulatory standards. Ensure the component source is authorized to avoid counterfeit risks.

Memory IC Selection Notes

Select this part when a 1.8V to 3.6V supply is available and a 3 MHz SPI interface is sufficient. Consider the 8-lead SOIC package for surface mount assembly. Evaluate the 20 ms write cycle time against system timing requirements. Verify that the block write protection levels meet security needs.

Memory IC Part Context

This component belongs to the AT25080/160/320/640 family of serial EEPROMs. These devices share similar SPI interfaces and instruction sets but differ in memory density. The AT25080 provides 8K bits, while other variants offer higher capacities within the same package options.

Memory IC FAQ

How does the HOLD pin function during serial communication?

The HOLD pin pauses serial communication when brought low while SCK is low. It resumes when brought high while SCK is low, preserving the current serial sequence.

What is the maximum page write size for this device?

The device supports a 32-byte page write operation. Address rollover occurs if more than 32 bytes are transmitted in a single sequence.
