TS-8820-fpga

The TS-8820 is powered by a Lattice XP2 FPGA with 5000 LUTs. Many but not all of the features listed in chapter 5 are driven by FPGA logic. The hardware functionality described in this document is programmed in the FPGA at the factory by default. The TS-SOCKET System-on-Module (SoM) also has an FPGA, but when an FPGA is mentioned in this document it should be assumed that the TS-8820 FPGA is being discussed.

The SoM communicates with the TS-8820 FPGA using the MUXBUS, a simple address/data bus defined by embeddedTS and implemented in the SoM FPGA. TS-8820 application developers do not need to understand the full hardware stack that enables TS-8820 registers to be accessed in memory space. It is necessary to program the MUXBUS registers with values that work for the TS-8820. See ts8820ctl source code for an example.
