FPGAs play a vital role in today's most complex embedded system designs. With the significant drop in FPGA prices and the flexibility they offer, it’s no surprise that they are increasingly used in competitive global markets. FPGAs help businesses gain market strength, understand customer needs, build loyalty, enhance brand value, and achieve high profitability. But how can you bring your next innovative idea to market first? How do you control costs while maintaining profitability? And how do you protect your revenue and brand when launching mass-produced products? One key strategy is **pre-emptive market entry**. While companies focus on management, development, and marketing, the design phase often overlooks simplification. Many designers assume that choosing an FPGA with the lowest unit cost will lead to the lowest overall system cost and fastest time-to-market. However, this approach may require excessive design complexity and time-consuming support infrastructure. In the low-cost FPGA market, different technologies are available, and the choice of FPGA technology significantly impacts the complexity and completion time of the system. The **fundamental difference** between FPGAs lies in whether they use **non-volatile Flash technology** or **volatile SRAM technology**. Flash-based FPGAs offer single-chip operation and power-up capability, greatly simplifying system design and product integration. Unlike SRAM-based FPGAs, Flash FPGAs don’t need configuration upon power-up or undervoltage detection. They don’t require an MCU to load the device, eliminating the need for additional power management circuits, signal sources, layout, debugging, and testing. Their built-in power-up PLL instantly generates clock signals, allowing core logic and I/O to operate immediately. This predictable startup process lets designers focus on verification rather than integration challenges. When it comes to **controlling costs**, reducing the total system cost is a top priority for many companies. Designers shouldn't just focus on the unit price of an FPGA but also consider hidden costs. For example, non-volatile FPGAs reduce the need for extra components like CPLDs, clock generators, and reset controllers. Using fewer components lowers material costs, reduces board space, improves reliability, and decreases power consumption—leading to lower cooling and supply costs. While not all systems benefit from these reductions, using non-volatile FPGAs in future designs could be a wise decision. Beyond material costs, there are intangible expenses related to validating and verifying additional components. These can delay schedules and increase engineering costs, affecting productivity. During the design phase, considering product characteristics and manufacturing processes helps improve efficiency. Non-volatile FPGAs simplify testing, increase yield, reduce risk, and minimize EMI, suppliers, and inventory—leading to lower operational costs. Another critical concern is **protecting your investment**. The choice of FPGA technology affects design confidentiality, product reputation, and liability. With the rise of reverse engineering, pirated products can appear quickly, threatening intellectual property (IP). Once an FPGA replaces an ASIC, the system becomes vulnerable. Patents and litigation are often ineffective and costly, with uncertain outcomes. Even if a lawsuit is won, the company may lose valuable market time. Flash-based FPGAs offer a strong solution. Since their bitstream is stored internally, it cannot be intercepted. These devices are highly secure, and even if opened, only the structure is visible, not the actual content. Modern Flash FPGAs also include AES decryption cores for secure reprogramming and protection. In conclusion, the total cost of ownership depends on the choices made by embedded system designers, especially in selecting FPGA technology. Care must be taken to account for material costs, design efficiency, and hidden risks like IP theft and product liability. Non-volatile Flash-based FPGAs provide a unique alternative to SRAM FPGAs and may be the best choice for your next embedded system design.
