AT25FF081A-UUN-T

Memory IC Overview

The AT25FF081A-UUN-T is an 8 Mbit SPI NOR flash memory component manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.65V to 3.6V and supports Single, Dual, and Quad SPI interfaces with clock frequencies up to 104 MHz. The device is housed in an 8-lead Ultra Small Thin Plastic Package (USON) and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports Single, Dual, and Quad SPI interface modes for flexible data transfer speeds
• Ultra-low energy consumption architecture designed for extended battery life
• Wide operating voltage range accommodating diverse system power requirements

Memory IC Applications

• Low-power wearable devices requiring minimal footprint
• IoT sensor nodes and remote monitoring systems
• Portable consumer electronics with strict size constraints

Memory IC Procurement Notes

Verify the specific package suffix 'UUN' corresponds to the required 8-lead USON form factor during procurement. Confirm that the manufacturer designation matches Renesas Electronics Corporation or Dialog Semiconductor to ensure authenticity. Check for RoHS compliance documentation as standard for this series. Ensure the ordering part number includes the '-T' suffix if tape and reel packaging is required for automated assembly processes.

Memory IC Selection Notes

Select this component when a small physical footprint is critical alongside low power consumption. The wide voltage range allows compatibility with various logic levels without additional level shifters. Consider the 104 MHz maximum clock speed for applications requiring moderate read performance. Verify that the 8 Mbit capacity aligns with the specific code and data storage needs of the target design.

Memory IC Part Context

This part belongs to the AT25FF081A family of SPI NOR flash memories. It shares architectural similarities with other members like the AT25EU0081A but differs in package type and specific electrical characteristics. The USON package distinguishes it from SOIC variants, offering a thinner profile suitable for compact modern electronic designs.

Memory IC Replacement Considerations

The AT25SF081-MAHD-T is listed as obsolete. Potential replacements include the AT25FF081A-MAHN-T or AT25SF081B-MAHB-T, though these utilize different packages. Verify pinout compatibility and package dimensions before substituting.
