Preliminary
;
The Eclipse-II Product Family includes up to 24 dual-port 2,304-bit RAM modules for
implementing RAM, ROM, and FIFO functions. Each module is user-configurable into four
different block organizations and can be cascaded horizontally to increase their effective width, or
vertically to increase their effective depth as shown in
;
.
!""#
The number of RAM modules varies from 4 to 24 blocks for a total of 9.2 K to 55.3 K bits of
RAM. Using two "mode" pins, designers can configure each module into 128 x 18 (Mode 0), 256
x 9 (Mode 1), 512 x 4 (Mode 2), or 1024 x 2 blocks (Mode 3). The blocks are also easily
cascadable to increase their effective width and/or depth (see
;
).
