E.1. About memory expansion

You can fit a static memory expansion board to the baseboard. There are four chip select signals available for use by the static expansion board. Each of these can select 64MB of SRAM.

The block diagrams for a typical memory board is shown in Figure E.1.


Different expansion boards might have different features. For example, the links selecting which chip select to use might be omitted. See the documentation provided with your memory board for details on signals and link options.

PISMO signal nCS4, nSTATICCS7, is tied permanently HIGH on the baseboard.
