AT25EU0041A-SSHN-T

Product Overview

The AT25EU0041A-SSHN-T from Renesas Electronics Corporation is a non-volatile flash memory IC organized as 512K x 8 for a total memory size of 4Mbit. It uses NOR technology and communicates through an SPI interface with Quad I/O support at 85 MHz. The device operates from a 1.65V to 3.6V supply and uses an 8-SOIC surface mount package with a 0.154 inch, 3.90 mm body width. Its ambient operating temperature range is -40°C to 85°C, for designs that need serial flash storage in compact board layouts.

Design & Procurement Notes

Designers should confirm that the host controller supports SPI with Quad I/O and can operate with a 1.65V to 3.6V memory supply. At 85 MHz, attention to trace length and signal integrity is important for reliable serial communication. The 8-SOIC package requires a surface mount land pattern compatible with the 0.154 inch, 3.90 mm body width. The 512K x 8 organization and 4Mbit capacity should be matched to the firmware, configuration, or data retention needs of the system. The -40°C to 85°C ambient temperature range should be checked against the expected operating environment.
