Product Summary
The AT45DB041B-SU is an SPI compatible serial interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. Its 4,325,376 bits of memory are organized as 2048 pages of 264 bytes each. In addition to the main memory, the AT45DB041B-SU also contains two SRAM data buffers of 264 bytes each. To allow for simple in-system reprogrammability, the AT45DB041B-SU does not require high input voltages for programming. The device operates from a single power supply, 2.5V to 3.6V or 2.7V to 3.6V, for both the program and read operations. The AT45DB041B is enabled through the chip select pin (CS) and accessed via a threewire interface consisting of the Serial Input (SI), Serial Output (SO), and the Serial Clock (SCK).
