Overview
The Trenz Electronic TE0835 is an extended-grade module based on Xilinx Zynq UltraScale+ RFSoC. The module is equipped with 4x 8Gb DDR4 SDRAM Memory, 2x 512Mb SPI Flash Memory, USB2.0, Ethernet Transceiver and 2x Samtec Razor Beam Borard to Board (B2B) Connectors. The system controller CPLD is provided by Lattice MachXO2.
The Zynq UltraScale+ RFSoC family integrates key subsystems for multiband, multi-mode cellular radios and cable infrastructure (DOCSIS) into an SoC platform that contains a feature-rich 64-bitquad-core Arm Cortex-A53 and dual-core Arm Cortex-R5 based processing system.

JTAG Interface
JTAG access to the Xilinx UltraScale+ MPSoC is through B2B connector JM1. JTAG signals routed directly through the CPLD to FPGA. Access between CPLD and FPGA can be multiplexed via JTAGEN (logical one for CPLD, logical zero for FPGA) on B2B. When the CPLD_JTAGEN is 0 or off, it provides FPGA access and when it is 1 or ON, it provides CPLD access.
