Renesas ISLUSPLUS-UC2DEMO1Z

Overview

The ISLUSPLUS-UC2DEMO1Z from Renesas is a demonstration board designed to deliver a complete, pre-validated power supply reference solution for Xilinx Zynq UltraScale+ MPSoC devices operating in Use Case 2 configuration (always-on, power- and efficiency-optimized). It integrates eleven regulated output rails-including 0.85V/31A (VCCINT), 0.85V/4.35A (VCCINT_VCU/VCCBRAM), 1.8V/2.04A (VCCAUX), and 1.2V/10.6A (VMGTAVTT)-with PMBus interface support and hardware-based power-up/power-down sequencing.

For engineers reviewing the ISLUSPLUS-UC2DEMO1Z datasheet, ISLUSPLUS-UC2DEMO1Z pinout, ISLUSPLUS-UC2DEMO1Z application, or ISLUSPLUS-UC2DEMO1Z equivalent, this board serves as a production-ready evaluation platform for validating Zynq US+ power architecture, verifying rail consolidation strategies, and accelerating bring-up of high-density FPGA-based systems requiring strict sequencing, remote sensing, and digital voltage margining.

Technical Context

The ISLUSPLUS-UC2DEMO1Z implements a multi-rail, mixed-signal power architecture using Renesas' integrated power modules (ISL8271M, ZL9006M, ZL9010M, ISL8277M) and buck regulators (ISL85003, ISL85410, ISL85415), all coordinated by the ISL8702A quad sequencer. Each rail is independently adjustable via resistor dividers or PMBus commands, supporting fine-grained voltage margining across critical logic, I/O, and transceiver domains.

Input conditioning includes Kelvin remote sensing on select rails, synchronous rectification, and configurable soft-start timing. The board supports full-load operation across its 8V–13.2V input range with measured ripple under 20mV peak-to-peak on all outputs and load transient response within 100µs for step changes up to 12A on Rail 1.

FAQ

What is the primary purpose of the ISLUSPLUS-UC2DEMO1Z?

The ISLUSPLUS-UC2DEMO1Z is a Renesas demonstration board engineered to serve as a turnkey power reference design for Xilinx Zynq UltraScale+ MPSoC devices configured in Use Case 2 (always-on, optimized for power and efficiency). It validates the complete 11-rail power architecture-including sequencing, PMBus telemetry, and remote sensing-enabling faster system integration and reducing risk in FPGA-based industrial and embedded applications. The ISLUSPLUS-UC2DEMO1Z eliminates the need for custom power design iteration during early development phases.

Which Zynq UltraScale+ devices does the ISLUSPLUS-UC2DEMO1Z support?

The ISLUSPLUS-UC2DEMO1Z is explicitly validated for the Xilinx Zynq UltraScale+ ZU11EG, ZU15EG, ZU17EG, and ZU19EG MPSoC devices. Its rail voltages, current capabilities, and sequencing timing align with the power delivery requirements defined in Xilinx UG578 for Use Case 2 configurations. The ISLUSPLUS-UC2DEMO1Z provides terminal blocks and schematics mapped directly to Zynq US+ power domains such as VCCINT, VCCAUX_IO, VMGTAVTT, and VCCO_PSIO.

Does the ISLUSPLUS-UC2DEMO1Z support voltage adjustment, and how is it implemented?

Yes, the ISLUSPLUS-UC2DEMO1Z supports voltage adjustment on five output rails: Rail 1 (0.72V/0.85V), Rail 2 (0.85V/0.9V), Rail 5 (1.1–1.5V), Rail 9 (0.9V), and Rail 10 (1.2–3.3V). Adjustment is achieved either via external resistor dividers (e.g., RVSET1, R45, R56) or through PMBus commands using the ISL8271M and other compatible regulators. The ISLUSPLUS-UC2DEMO1Z User's Manual (UG154) provides exact resistor values and equations for each configurable rail.

What interfaces and connectivity options are available on the ISLUSPLUS-UC2DEMO1Z?

The ISLUSPLUS-UC2DEMO1Z features a 2×5 PMBus header (XS1) for SCL/SDA, EN, ALERT, and VDD signals; a 2-pin terminal block (J1) for enable control; an 8–13.2V input terminal block (J2); and eleven dedicated 2-pin terminal blocks (J3–J14) for individual rail access. All output rails include Kelvin remote sense connections where applicable. No USB, JTAG, or debug interfaces are present-the ISLUSPLUS-UC2DEMO1Z is strictly a power delivery evaluation platform.

Is the ISLUSPLUS-UC2DEMO1Z RoHS-compliant and suitable for industrial environments?

Yes, the ISLUSPLUS-UC2DEMO1Z is RoHS-compliant and built with industrial-grade components including Murata GRM capacitors, Wurth Elektronik power inductors, and Renesas ISL8271M/ZL9006M power modules rated for extended temperature operation. Its PCB layout follows thermal and EMI best practices for high-current switching regulators, and the board has been validated for continuous operation at full load across its specified input range. The ISLUSPLUS-UC2DEMO1Z meets requirements for deployment in industrial embedded, test equipment, and prototyping environments.
