FAE Expert Insights
"The UN5F100 is an excellent entry-level FPGA for embedded applications. I have used this in numerous industrial control and communication projects. The 10K LUTs capacity handles most embedded designs comfortably. The low power consumption is genuine - I measured significantly lower static power than competing devices. The embedded RAM and DSP blocks are valuable for signal processing applications. The UniLogic tool is intuitive and the IP library covers most common needs. For cost-sensitive designs, this FPGA offers excellent value. I recommend the TQFP package for prototyping and BGA for production."

Frequently Asked Questions
How much logic can fit in 10K LUTs?
10K LUTs can implement: 1) 32-bit soft processor with peripherals. 2) Multiple UART/SPI/I2C controllers. 3) Simple video processing. 4) Digital signal processing algorithms. 5) Custom state machines and control logic. As a reference: 1 LUT ~ 1 gate equivalent. 10K LUTs ~ 100K-200K gates. A complete 32-bit RISC processor requires ~3K-5K LUTs. Complex designs may require the larger UN5F200 with 20K LUTs.
Estimate your logic requirements or contact us for FPGA sizing assistance.
What is the configuration time?
Configuration time depends on bitstream size and interface: Bitstream size for 10K LUTs: ~2-3 Mbits. SPI Flash at 50MHz: ~40-60ms. Parallel Flash: ~10-20ms. JTAG: varies with cable speed. For fast power-up requirements, use parallel configuration or compressed bitstream. The FPGA supports configuration decompression to reduce storage requirements and speed up configuration.
Use parallel configuration for fastest power-up, SPI Flash for simplest design.
Can I use this FPGA for video processing?
The UN5F100 can handle basic video processing: Simple format conversion, color space conversion, basic filtering. For HD video or complex processing, consider larger devices. The embedded DSP blocks help with video algorithms. Memory bandwidth is the limiting factor for high-resolution video. For VGA/SD video processing, this FPGA is adequate. For HD/4K video, use UN5F200 or larger devices.
Suitable for SD/VGA video. Contact us for HD video processing recommendations.
What clock speeds can the PLL generate?
The UN5F100 includes 4 PLLs with flexible clock generation: Input clock: 10MHz to 200MHz. Output clock: 1MHz to 400MHz. Clock multiplication and division supported. Jitter: typically <100ps. The PLLs can generate multiple clock phases and frequencies from a single input. This is useful for designs requiring multiple clock domains. Clock switching is glitchless for dynamic frequency changes.
Use PLLs for clock multiplication and multiple clock domains.
How do I estimate power consumption?
Power estimation steps: 1) Use UniLogic power estimator tool. 2) Enter logic utilization percentage. 3) Enter clock frequency and toggle rate. 4) Enter I/O count and switching activity. 5) Add static power from datasheet. Typical power: Static: 20-50mW. Dynamic: depends on design, 50-200mW typical. Total: 70-250mW for typical designs. For accurate estimation, synthesize your design and use the power analyzer.
Use power estimator early, then verify with actual design synthesis.
