CategorieMemory => Flash => 8 Mb
Description8Mbit 1.8V SPI Serial Flash
The SST25WF080 is a member of the Serial Flash 25 Series family and features a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. SST25WF080 SPI serial flash memory is manufactured with SST proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.

    The is a member of the Serial Flash 25 Series family and features a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. SST25WF080 SPI serial flash memory is manufactured with SST proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The SST25WF080 significantly improves performance and reliability, while lowering power consumption. The device writes (Program or Erase) with a single power supply of 1.65-1.95V for SST25WF080. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies. The SST25WF080 is offered 8-lead, 150 mils SOIC package. See Figure 2 for the pin assignment.

    Note: In AAI mode, the SO pin functions as an RY/BY# pin when configured as a ready/busy status pin. See "End-of-Write Detection" on page 12 for more information.

    Symbol SCK Pin Name Serial Clock Functions To provide the timing of the serial interface. Commands, addresses, or input data are latched on the rising edge of the clock input, while output data is shifted out on the falling edge of the clock input. To transfer commands, addresses, or data serially into the device. Inputs are latched on the rising edge of the serial clock. To transfer data serially out of the device. Data is shifted out on the falling edge of the serial clock. Flash busy status pin in AAI mode SO is configured as a hardware RY/BY# pin. See "End-of-Write Detection" on page 12 for more information. The device is enabled by a high to low transition on CE#. CE# must remain low for the duration of any command sequence. The Write Protect (WP#) pin is used to enable/disable BPL bit in the status register. To reset the operation of the device and the internal logic. The device powers on with RST# pin functionality as default. To temporarily stop serial communication with SPI Flash memory while device is selected. This is selected by an instruction sequence which is detailed in "Reset/Hold Mode" on page 5. To provide power supply voltage: 1.65-1.95V for SST25WF080
