The range of permitted Dual-Port RAM Megacell configurations is as follows:
Number of rows: 4, ...128
Number of cols: 2, ...128
Number of words: 8, ...16384
Bits per word: 1, ...64
Total size:
8, ...16384
Port A configuration: read/write, read-only
Port B configuration: read/write, write-only
The following table lists all DPR inputs and outputs and their pin capacitances. Pin
names are suffixed with the port nature A or B:

The following tables show the range of performances for particular Dual Port RAM con-
figurations, without BIST and without output load. Access time (tACC) and cycle time
(tCYC) refer to Max industrial conditions, whereas Dynamic Power dissipation refers to
typical conditions. All examples have the same configuration for both port A and port B,
with Read/Write capability.
