AT25XV041B-MAHV-T

AT25XV041B-MAHV-T is a SPI serial flash memory with dual-I/O support. It is a serial interface flash memory device for a wide variety of high-volume consumer and connected applications. It can be operated using modern lithium battery technologies over a wide input voltage range of 1.65V to 4.4V. It is designed for systems in which program code is shadowed from Flash memory into embedded or external RAM (code shadow) for execution, where code is updated over the air, where small amounts of data are stored locally in the flash memory. The erase block sizes of the AT25XV041B have been optimized to meet the needs of today's code and data storage applications. The device supports 256-byte page erase, as well as 4Kbyte, 32Kbyte, and 64Kbyte block erase operations. By optimizing the size of the erase blocks, the memory space can be used much more efficiently.
