    Question: How can I wire an SRAM to the FX2LP device for memory expansion. Please provide a pin to pin connection detail.

     

    Answer:

    Following is how the SRAM needs to be wired to the FX2LP device. Please use the pin assignments as shown below:

    SRAM to FX2
    ==========
    CE# to CS#
    OE# to OE#
    WE# to WR#
    D[7:0] to D[7:0]
    A[15:0] to A[15:0]
    GND to GND
    VCC to VCC

    The above is a very standard method of memory expansion on any 8051 microcontroller
