The SST26VF040A-80E/MF is a NOR Flash 4Mb, 2.3V to 3.6V, SPI,SDI,SQI, 80MHz, E temp, 8-DFN manufactured by Microchip. It is a non-volatile, read-only memory designed for use in embedded applications. It features a Serial Peripheral Interface (SPI) or Serial Quad I/O (SQI) interface, with an access time of 80 MHz. The memory device has an operating voltage range of 2.3V to 3.6V and allows the user to select from two power-saving modes. The SST26VF040A-80E/MF can be programmed in-system through the SPI, SDI, or SQI port, which decreases the programming time for applications that require frequent updates. The SST26VF040A-80E/MF is available in a 8-DFN package (4mm x 4mm) and is tested and guaranteed to meet standard extended-temperature (-40C to 85C) requirements.
