OVERVIEW
WinSystems' PCM-SDIO combines both four serial and 48 digital I/O lines onto a single PC/104 module. This can eliminate one board in a stack without sacrificing any features or benefits. The digital portion is further enhanced since its I/O can interface wtih up to 30 volt signals.
The controller is based upon a FPGA wtih both 16C554 UART and WS16C48-compatible cores. It supports various programmable input/output and interrupt configurations.
