AT25EU0011A-MAHN-T

Product Overview

The AT25EU0011A-MAHN-T from Renesas Electronics Corporation is a non-volatile NOR flash memory IC with a 1Mbit capacity organized as 128K x 8. The device uses an SPI - Quad I/O, QPI interface and operates at a clock frequency of 85 MHz. It is specified for a supply voltage range of 1.65 V to 3.6 V. It can be used in low-voltage embedded designs that require flash-based program or data storage. The part uses a surface-mount 8-UFDFN exposed-pad package with an 8-UDFN (2x3) package outline.

Key Features

• 1Mbit non-volatile NOR flash memory with a 128K x 8 organization.
• SPI - Quad I/O, QPI memory interface.
• 85 MHz clock frequency.
• 8 ms write cycle time for word or page operations.
• 1.65 V to 3.6 V supply voltage range.
• Surface-mount 8-UFDFN exposed-pad package, 8-UDFN (2x3).

Applications

• Firmware or program storage in embedded controllers.
• Non-volatile configuration data storage in low-voltage devices.
• Compact code or data storage in surface-mount embedded assemblies.

Design & Procurement Notes

Design considerations should account for the 1.65 V to 3.6 V supply range and the SPI - Quad I/O, QPI interface, including host controller support for the selected interface and the 85 MHz clock. The 8 ms word or page write cycle should be included in system write timing budgets. Layout planning should accommodate the surface-mount 8-UFDFN exposed-pad package and the 8-UDFN (2x3) package outline. The 128K x 8 organization defines the addressable data structure for the 1Mbit memory, which should be reflected in firmware memory maps and buffer allocation.
