PC104P is in stack-PC form factor and complies with PCIe104 TYPE2 peripheral board specification. It offers a rapid development platform for applications intending to use MPF500T-1FCG1152 (or MPF300T) Polar Fire FPGA from Microchip. The card includes 8GB of 32bits wide DDR4, HPC FMC compatible with Vita 77.1 standard, SFP+, Display Port, SATA, USB JTAG, and user and power GOOD LEDs. PC104P also includes one End Point (EP) PCIe x4 GEN2 on StackPC bottom connector for interface to a host card.
This PCIe104 TYPE2 peripheral board comes with stack up and stack down connectors. However, the board can be only used as End-Point in stack-up configurations for connection to StackPC host; and stack-down connector is used for connection to an adjacent peripheral module.
PC104P uses the powerful, low-power, and high-security PolarFire FPGA from Microsemi. It is based on the MPF500T-1FCG1152E (or MPF300T-1FCG1152E) FPGA with an industry-standard footprint, low power, high security, ample processing resources, and many hardcore IPs like JESD204B, RISC V, etc. With its relatively low cost, it can be suitable for applications where cost and low-power and security are important. The module is compatible with some SoMs from Trenz
Due to the absence of PCIe x4 link shifting in this board, any other peripheral module with PCIe connection should be under it or if no PCIe link is needed then it can be stacked down above it as shown in the diagram below.
The board comes with an IO card that connects to the board Via an LSHM connector. It provides interfaces for Display port, SATA, and USB.
A High Pin Count (HPC) FMC site is also provided on this board.
The SFP+ connector is not fully placed on the PCB but in our enclosure, that connector is fully supported mechanically by the enclosure. Applications that do not need SFP+ can have that not populated or removed.
If PCIe104 TYPE1 card is required then PC104P can be adopted with some rework.
The stack PC from 7STARLAKE, OXY5741A Scalable PCIe/104 CPU Module, is a suitable development platform for this card.
