Stork TPMC866-11 Circuit Board

STORK TPMC866-11 Circuit Board is an 8-channel PCI Mezzanine Card (PMC) module offering eight RS422 serial interfaces on a standard single-width 32‑bit PMC carrier. It provides front I/O via an HD50 SCSI‑2 type connector and back I/O through 64‑pin Mezzanine P14, with 64‑byte transmit and 64‑byte receive FIFOs per channel and a maximum data rate of 460.8 kbaud per channel. Each RS422 channel uses differential TxD+/TxD− and RxD+/RxD− signals with a 120 Ω termination between RxD+ and RxD− on each channel. The TPMC866 family is PCI target PMC hardware, delivering interrupts on a single PCI INTA line and a combined front/back I/O footprint. Power is drawn from the +5 V rail (typical 15–85 mA) and the +3.3 V rail (typical around 100 mA), and the module operates from 0 °C to +70 °C. This STORK-branded TPMC866-11 variant is listed as discontinued by the TPMC866 family documentation.
