Chip Talk > Maximizing Flexibility with SiP Technology in FPGA Design
Published July 22, 2025
In the ever-evolving world of microelectronics, one of the prominent trends is the relentless drive to optimize system integration and minimize the physical footprint of components to meet the growing demands of industries like the Internet of Things (IoT) and Edge AI. A notable player in this arena, Efinix, is leveraging System-in-Package (SiP) technology to enhance the capabilities of Field-Programmable Gate Arrays (FPGAs). Efinix's blog provides insights into their latest advancements.
SiP packages integrate multiple semiconductor dies into a single package. This approach enables the stacking of different technology nodes within a small footprint, combining components like microprocessors, memory, and power management systems. The strategic integration not only reduces the size of the end device but also cuts down on power consumption and enhances signal integrity due to shorter electrical paths.
Moreover, SiP configurations significantly reduce design complexity and time-to-market by offering pre-integrated solutions compared to the costly and time-consuming development of custom Application-Specific Integrated Circuits (ASICs). FPGAs within these systems add a layer of configurability, offering a responsive solution to evolving market demands and standards.
Leveraging FPGAs in SiP offers several advantages, notably the flexibility to adapt to new standards and technologies without the extensive cost and resource implications of ASIC redesigns. As standards evolve, developers can update FPGA-based solutions to maintain technological relevancy, a key advantage for markets subjected to rapid technological advances.
The adaptable nature of FPGAs means they remain viable longer than ASICs, which risk obsolescence from fixed functionality that cannot be updated once manufactured. Thus, SiP solutions with FPGAs fit seamlessly into markets like edge computing where performance and adaptability are paramount.
Efinix, with its Trion and Titanium FPGA families, exemplifies how SiP technology can enhance electronic design. For instance, the small but powerful Ti60F100 package combines flash memory and HyperRAM in a compact form ideal for industrial sensor applications, while the Ti180 package integrates 2Gb LPDDR4 memory, alleviating the need for external memory buses and maintaining user I/O options.
These innovative packaging solutions solve traditional dilemmas of FPGA design, where choices must be made between memory interface integration versus available I/O options. The Ti180, for example, achieves a balance that maximizes I/O pins without compromising on embedded memory.
The ongoing research and development in SiP technology suggest a promising future with potential new offerings tailored to future FPGA families. Given their cost-efficiency, short time-to-market, and adaptability, SiP packages are poised to become stalwarts in electronic design, especially in fields requiring robust edge devices.
