FAE Expert Insights
"The PGL50H is my go-to recommendation for industrial customers needing FPGA capabilities without the cost of high-end devices. I've deployed this in numerous PLC systems, motor controllers, and communications gateways. The 50K logic elements handle most industrial control algorithms comfortably, and the 120 DSP blocks are sufficient for multi-axis motor control. The high-speed I/O supports Gigabit Ethernet and industrial protocols like EtherCAT. Power consumption is reasonable - typically 2-3W in active operation. The price point is very competitive compared to similar capacity devices from Xilinx and Intel. For customers transitioning from international suppliers, the PGL50H offers a smooth migration path."

Frequently Asked Questions
What is the typical power consumption of PGL50H?
PGL50H power consumption varies with utilization: Static power: 150-250mW. Typical dynamic power: 1-2W for moderate designs. Maximum power: 3-4W for fully utilized devices. Power scales linearly with logic utilization and clock frequency. The device supports multiple power-down modes for power-sensitive applications. No heatsink is needed for most applications. Thermal analysis recommended for designs >2.5W.
Estimate power using PDS tool. No heatsink is needed for typical industrial applications.
Does PGL50H support Gigabit Ethernet?
PGL50H supports Gigabit Ethernet through soft IP cores and external PHY: GMII/RGMII interface to external Gigabit PHY. Soft Ethernet MAC IP available from Unisplendour. TCP/IP stack runs in embedded processor or soft core. Typical throughput: 800-900 Mbps with soft MAC. For higher performance, consider Titan series with hard MAC. Multiple Ethernet ports possible depending on I/O availability.
Use external PHY with RGMII interface. Evaluate throughput requirements for soft vs hard MAC.
What industrial protocols can PGL50H implement?
PGL50H can implement various industrial communication protocols: EtherCAT slave controller (soft IP). PROFINET IO device. Modbus TCP/RTU master and slave. CAN bus controller with external transceiver. Ethernet/IP adapter. CC-Link IE Field. These protocols are implemented using soft cores in the programmable fabric. Reference designs and IP cores available from Unisplendour and third parties. I/O count and speed requirements determine number of concurrent protocols.
Check IP core availability for specific protocols. Contact FAE for reference designs.
How many motor control axes can PGL50H support?
PGL50H can support multiple motor control axes depending on complexity: Simple stepper control: 8-16 axes. Vector control (FOC) for PMSM/BLDC: 4-6 axes. Servo control with advanced algorithms: 2-4 axes. Each axis typically requires: 2-4K logic elements, 2-4 DSP blocks for PID and transforms, encoder interface logic. Reference designs available for 3-phase motor control. External gate drivers and power stage required.
Evaluate based on control algorithm complexity. Contact FAE for motor control reference designs.
What configuration options does PGL50H support?
PGL50H supports multiple configuration modes: Active Serial (AS) from SPI flash - most common. Passive Serial (PS) from external processor. JTAG for debugging and programming. Configuration time: 50-200ms from SPI flash depending on bitstream size. Supports configuration decompression to reduce flash size. Multiple configuration images possible for fail-safe boot. Remote update capability through embedded processor.
Use SPI flash for standalone operation. Use JTAG for development. Implement dual-image for critical applications.
Is PGL50H suitable for functional safety applications?
PGL50H can be used in functional safety applications with appropriate design: Implement dual-channel architecture in fabric. Use external safety monitor circuits. Diagnostic coverage through built-in self-test. Temperature and voltage monitoring. Note: PGL50H is not certified for specific SIL levels. Safety certification requires system-level design and validation. Contact Unisplendour for safety manual and failure mode analysis.
