Typical Applications
5CSXFC4C6U23C8N is suitable for 7 applications: Industrial Motor Control, Programmable Logic Controller (PLC), Industrial Ethernet Gateway, Machine Vision Pre-Processor, Video Surveillance DVR/NVR, Software-Defined Radio Baseband, Medical Diagnostic Imaging.
Industrial Motor Control
The 5CSXFC4C6U23C8N is ideal for industrial motor control systems where its dual ARM Cortex-A9 HPS runs EtherCAT, PROFINET, or CANopen communication stacks while the FPGA fabric executes deterministic torque and speed control loops with sub-microsecond latency. Its 40K logic elements and variable-precision DSP blocks accelerate Park/Clarke transforms, SVPWM modulation, and encoder interface logic without taxing the CPU. The integrated transceivers support industrial Ethernet at multi-Mbaud rates, and the industrial temperature grade (per C8N suffix) ensures reliable operation in factory-floor enclosures with ambient temperatures from -40C to +85C.
Recommended
Programmable Logic Controller (PLC)
In PLC architectures, the 5CSXFC4C6U23C8N replaces traditional MCU + CPLD combinations by consolidating scan logic, communication, and I/O handling on a single SoC. The HPS executes the IEC 61131-3 runtime (CODESYS or OpenPLC) while the FPGA fabric implements deterministic I/O scan with cycle times under 100 microseconds. The 224 user I/Os accommodate digital input/output banks, and the SD/MMC peripheral logs process data to industrial memory cards. The exposed-pad package and 28 nm process keep SoC power under 2W typical, eliminating active cooling in DIN-rail mounted PLC chassis.
Recommended
Industrial Ethernet Gateway
The 5CSXFC4C6U23C8N serves as a multi-protocol industrial Ethernet gateway, with the HPS running protocol stacks (EtherCAT master, PROFINET device, Modbus TCP) and the FPGA implementing hardware-accelerated frame processing. The integrated transceivers support 100 Mbit and gigabit Ethernet PHY interfaces directly, while the 40K logic elements accommodate wire-speed packet inspection, QoS queuing, and network diagnostics. Dual ARM Cortex-A9 cores enable parallel handling of multiple industrial protocols with isolated memory domains, and the on-chip memory provides low-latency buffer space for time-sensitive networking (TSN) applications.
Recommended
Machine Vision Pre-Processor
For machine vision pre-processing, the 5CSXFC4C6U23C8N combines a camera interface (MIPI CSI-2, parallel CMOS, or GigE Vision via transceiver) with hardware-accelerated image processing pipelines in the FPGA fabric. The variable-precision DSP blocks execute Sobel filters, convolutions, and morphological operations at line rate, while the HPS runs object detection algorithms using OpenCV or vendor SDKs. The 224 user I/Os handle illumination control, trigger synchronization, and reject signal routing. Industrial temperature operation and the 672-UBGA package's robust thermal envelope suit factory vision systems with continuous duty cycles.
Recommended
Video Surveillance DVR/NVR
In video surveillance DVR/NVR applications, the 5CSXFC4C6U23C8N handles multi-channel H.264/H.265 transcoding offload in the FPGA fabric while the HPS runs the storage management, network video recorder (NVR) software, and web interface. The 40K logic elements accommodate multiple encoder cores operating at D1/720p/1080p resolutions simultaneously, and the integrated transceivers support SATA III for direct HDD attachment or 10 GbE uplink for NVR clustering. The dual Cortex-A9 cores enable Linux-based ONVIF/RTSP streaming servers with hardware-accelerated encryption for secure remote viewing.
Recommended
Software-Defined Radio Baseband
For SDR baseband designs, the 5CSXFC4C6U23C8N delivers hardware-accelerated FFT, channelization, and modulation/demodulation in the FPGA fabric while the HPS runs protocol stacks (LTE, Wi-Fi, custom waveforms) under Linux. The variable-precision DSP blocks support fixed- and floating-point signal processing essential for adaptive modulation, and the integrated transceivers handle ADC/DAC interfacing at RF frequencies. The 224 user I/Os accommodate GPIO for RF front-end control (attenuators, switches, PLLs), and the industrial temperature range suits outdoor base station deployments.
Recommended
Medical Diagnostic Imaging
In medical diagnostic imaging systems (ultrasound, endoscopy, patient monitoring), the 5CSXFC4C6U23C8N provides a deterministic FPGA fabric for real-time beamforming and signal conditioning alongside the HPS running patient interface software, DICOM network stacks, and display rendering. The 40K logic elements accommodate ultrasound beamformer pipelines for 32-64 channel probes, and the variable-precision DSP blocks execute finite impulse response (FIR) filters and envelope detection. The industrial temperature grade meets IEC 60601-1 reliability expectations when paired with appropriate isolation, and the 672-UBGA package supports compact handheld designs.

Key Differentiators
- Pin-compatible logic density scaling within the same 672-UBGA footprint (vs 5CSXFC2C6U23C8N (25K LE) and 5CSXFC6C6U23C8N (~110K LE))
- Speed grade flexibility within the same 40K LE design (vs 5CSXFC4C6U23C7N (C7) and 5CSXFC4C6U23C6N (C6))
- Automotive-grade upgrade path with same 672-UBGA package (vs 5CSXFC4C6U23A7N (A7 automotive))
Design Notes
The 672-UBGA package requires a minimum 4-layer PCB stack-up with dedicated ground and power planes beneath the device. Estimate: at least 1 oz copper on outer layers with 0.5 oz inner planes, plus a 6x6 via array thermal relief pattern under the exposed pad. Maintain controlled-impedance (90 ohm differential) routing for transceiver channels with maximum 4-inch length matching to within 5 mils. Reference the Cyclone V SX board design guidelines for break-out routing and BGA fanout recommendations.
Estimated: at typical SoC power of 1.5W (HPS at 600 MHz + moderate FPGA utilization), the 672-UBGA package theta_JA of approximately 15 C/W produces a 22.5C junction temperature rise above ambient. At 85C industrial ambient, junction reaches 107.5C, well within the 100C (industrial) limit. For designs with >70% FPGA fabric utilization or HPS at maximum 600 MHz with both cores active, attach a heatsink or design substantial copper pour (at least 2 sq inches) to maintain thermal margin.
Critical: do not power the HPS before the FPGA configuration completes, unless the design intentionally supports early HPS boot. The HPS reset and clock sequence must follow the Cyclone V SX hardware design guidelines to avoid latch-up. Common mistake: omitting the external reset IC for the HPS cold-boot sequence - without it, the HPS may enter undefined states on power-up. Always include the recommended power sequencing circuit and verify with oscilloscope measurements on prototype boards.
Transceiver channels on the 5CSXFC4C6U23C8N require AC-coupling capacitors (typically 100 nF) on each serial data line, placed close to the device pin. Maintain 90 ohm differential impedance with matched trace lengths (within 150 mil for lanes in the same group). For multi-gigabit rates (3+ Gbps), use 5 mil trace width with 8 mil trace spacing on a 4-layer stack-up. Always validate transceiver channel loss budgets using the Cyclone V SX transceiver toolkit in Quartus Prime.
Separate analog and digital ground planes if your design mixes sensitive analog inputs with FPGA digital switching. The HPS analog reference pins (VCC_AUX, VCC_PLL) require their own filtered supply rails, ideally using ferrite beads and 10 uF + 100 nF decoupling. Place all decoupling capacitors as close to the BGA balls as the breakout routing allows, with vias placed within 1 mm of each cap pad. Reference the Quartus Prime board design files for example decoupling assignments.
