The Substrate is a 66-pin ceramic pin grid array. The module is configured with four separate chip enable and write enable inputs and 32 separate I/Os. This, along with the small footprint, provides the end user with a large degree of flexibility in board layout and memory configuration. In addition, with the large number of pins and the growth path being implemented, the module will be able to grow to 16 megabits.
