PCM-DOC-D48-C 48MB PC/104 Flash module PCM-DOC-D72-C 72MB PC/104 Flash module PCM-DOC Profile - The module measures 3.6" x 3.8" PCM-DOC-D144-C 144MB PC/104 Flash module ® (90mm x 96mm). If a DIP DiskOnChip2000 of 48MB PCM-DOC-D288-C 288MB PC/104 Flash module or larger is ordered, its socketed height exceeds the 0.435" primary side dimension. This requires that the DiskOnChip® TSOP-II mounted on PCM-DOC device be soldered directly into the board or that the PCM-DOC-T8-C 8MB PC/104 Flash module PCM-DOC be mounted on the top of the PC/104 stack.
