Alliance Memory, Seriell NOR 128 MB Seriellt flash-minne, 8 Ben, SOP

The Alliance Memory serial interface Flash memory device designed for operating on a single power supply from 2.7 to 3.6V with current consumption as low as 0.2μA at deep power-down in which program code is shadowed from Flash memory into embedded or external RAM for execution. The flexible erase architecture of the device with its page erase granularity is ideal for data storage as well, eliminating the need for additional data storage devices. There are 65,536 programmable pages 256 Bytes each configured in the device and up to 256 Bytes can be programmed at a time. The groups of 16 4KB sector erase, groups of 128 32KB block erase, groups of 256 64KB block erase or the entire chip (chip erase) allow Pages to be erased. The device has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors afford greater flexibility for applications requiring data and parameter to be stored.
