Renesas enters FPGA market with sub-5000 gate devices for consumer & IoT

New Renesas ForgeFPGA family targets high-volume applications needing less than 5,000 logic gates, with initial device sizes costing less than $0.50 in volume and with standby power of less than 20 microamps.

Renesas Electronics Corporation has entered the field-programmable gate array (FPGA) market with a new line of what it said are very low-cost, very low-power devices. The ForgeFPGA family will address the underserved market need for relatively small amounts of programmable logic that can be quickly and efficiently designed into cost-sensitive applications.

The ForgeFPGA devices will provide dramatic cost savings versus other alternatives, including non-FPGA designs. By providing a high level of integration, they reduce overall board and system costs. Their projected price in volume of well under US$ 0.50 opens up applications that previously couldn’t use FPGAs due to cost constraints, including high-volume consumer and IoT applications.

The new FPGAs will address applications requiring less than 5,000 gates of logic, with initial device sizes of 1K and 2K look up tables (LUTs). Standby power of less than 20 microamps is projected for the first devices, about half the power of competing devices. Users will be able to download the development software at no cost and with no license fees. The software offers two development modes to accommodate both new and experienced FPGA developers: a “macrocell mode” that uses a schematic capture-based development flow, and an “HDL” mode that provides a familiar Verilog environment for FPGA veterans.

The ForgeFPGA family development team is the same group that introduced the GreenPAK programmable mixed-signal devices at Silego Technology, which came into the Renesas portfolio as part of the recently completed Dialog Semiconductor acquisition. The new FPGAs will use the same business model and infrastructure as the GreenPAK line: free, easy-to-use software with no license fees, and available worldwide applications support. This model has proved successful, with billions of GreenPAK devices already shipped amid continued growth.

“It’s exciting to see an established semiconductor vendor like Renesas tackling a long-ignored portion of the FPGA market: small, low-cost FPGAs that sip microwatts in standby mode,” said Steve Leibson, principal analyst, TIRIAS Research. “Having scooped up programmable device maker Silego with its acquisition of Dialog earlier this year, Renesas seems determined to repeat Silego’s previous success with its ultra-low-end GreenPAK line of programmable mixed-signal devices and super-simple design tools, this time in a low-end FPGA line that will appeal to many companies who just need a bit of programmable logic – a thousand gates or so – to get the job done in myriad products including billions of embedded sensors and IoT devices.”

Another analyst, Joe Hoffman, a contributing analyst at SAR Insight & Consulting, said via LinkedIn, “This is one of the most exciting announcements I’ve seen in a long time. 5K gate applications at less than $0.50 in volume and 20 µA. Best of all, I’m tempted to get the no-cost software and development kit.”

Speaking for Renesas, Davin Lee, vice president of the mixed-signal division in the company’s IoT and infrastructure business unit, said, “We are eager to extend our leadership in the small, low-cost, programmable market into FPGAs. We know from experience and from direct conversations that these devices will appeal to companies large and small in numerous markets around the world.”

Flex Logix said it supplied the eFPGA and software for the new ForgeFPGA family.

Key features of the new ForgeFPGA family are:

  • Very low power as low as 20 microamps standby.
  • Very low price in volume of well under US$ 0.50.
  • Free, downloadable software with no license fees that includes both schematic capture and HDL modes.
  • Proven ability to deliver very high volumes

Renesas is preparing to offer multiple of what it calls “Winning Combinations” featuring the new ForgeFPGA devices with complementary MCU, analog, power and timing devices. Its winning combinations solutions provide an easy-to-use architecture, simplifying the design process and significantly reducing design risk for customers in a wide variety of applications.

Engineering samples are available now, along with beta design software and a prototype development kit. The first ForgeFPGA device, the 1K LUT offering, is expected to be available in production quantities in Q2 2022.
