Advantages of Using Gate Arrays for Mass Production
Customizing mass-production sets to use Gate Arrays can result in several advantages.
| Low Cost | Stabilization of component procurement | Security |
Low Cost
Gate Arrays can be purchased for less than a dollar per unit. And for a given process, they can be packaged smaller than FPGAs, thereby reducing the circuit area and contributing to a reduction of total cost.
Stabilization of component procurement
Gate Array is a custom product, and can hence be delivered in stable quantities based on your demand forecast information. NEC Electronics has the flexibility to cope with increased demands and long product life.
Security
When using FPGA, the customer's proprietary circuit data is stored on a ROM, and FPGA is a general-purpose product. Hence, the circuit data can be intercepted and duplicated by monitoring the bit stream between the ROM and the FPGA during start-up. With Gate Arrays, the customer’s proprietary circuit design is hard-wired onto the semi-custom ICs, making it impossible to duplicate
