The AT25SF041B-SSHD-T from Renesas (formerly Adesto/Dialog) is a 4 Mbit SPI Serial Flash memory device supporting Single, Dual, and Quad I/O operations. Organized as 512K x 8 bits, it operates at clock frequencies up to 108 MHz for high-speed read operations in Quad I/O mode. The device provides multiple erase block sizes (4 KB, 32 KB, 64 KB) for flexible data management, 256-byte page programming, and comprehensive write protection mechanisms. It operates from 2.5 V to 3.6 V supply in the -40°C to +85°C temperature range.

The AT25SF041B uses standard SPI command protocols for all operations. Read operations support Standard SPI (single data line), Dual Output, Dual I/O, Quad Output, and Quad I/O modes for increasing throughput. Programming is performed on a 256-byte page basis, with the device internally handling program and erase timing. Erase operations support 4 KB sector, 32 KB block, 64 KB block, and full chip erase commands. Write protection is implemented through Status Register bits and hardware WP pin. Deep power-down mode reduces standby current to microamp levels.
