Introduction: The Growing Challenge of Semiconductor Discontinuation
In today's industrial electronics landscape, manufacturers face a critical challenge: ensuring long-term availability of key semiconductor components. As major semiconductor companies discontinue older product lines or exit specific markets altogether, many industrial systems with decades-long lifecycles risk becoming unsupportable. This is particularly problematic for applications in industrial automation, measurement instrumentation, and control systems.
Epson's ASIC (Application-Specific Integrated Circuit) solutions directly address this challenge by providing custom-designed replacements for discontinued ICs and programmable logic devices. With over 40 years of experience in ASIC design and manufacturing since starting the business in 1982, Epson offers one of the most comprehensive solutions for companies seeking to secure their supply chains against semiconductor obsolescence.

Applications and Use Cases

Epson's ASIC solutions are primarily targeted at industrial applications where long lifecycle support is critical:
1. Reproduction of Discontinued ASICs
When semiconductor manufacturers discontinue specific IC products, Epson can create functional replicas that maintain complete pin and function compatibility. This allows manufacturers to continue production without system redesign, providing:
Power supply, pin assignment, and functional compatibility
Customized I/O characteristics matching original specifications
Support for 5V power supply systems common in industrial equipment
Options for enhancing functionality beyond the original design
2. Replacement for Programmable Logic Devices
As FPGA and CPLD products reach end-of-life or face supply constraints, Epson offers fixed-function ASIC alternatives with advantages in unit cost, power consumption, and long-term availability:
Direct replacements for Lattice, Intel (Altera), and AMD (Xilinx) programmable devices
Elimination of configuration ROM requirements
Reduced power consumption compared to FPGA equivalents
Integration of multiple CPLDs into a single chip
3. Industrial System Longevity
Epson ASICs are particularly valuable for industrial equipment with expected service lives of 10-20+ years:
PLC (Programmable Logic Controllers)
Industrial displays and HMI systems
Servo motor controllers and inverters
CNC (Computer Numerical Control) systems
Precision measurement instruments
Why Choose Epson ASIC Over FPGAs and CPLDs?
When comparing semiconductor solutions for long-lifecycle industrial applications, Epson ASICs offer several advantages over programmable logic alternatives:
Feature | ASIC | CPLD | FPGA |
Unit price | ✓ | ||
No NRE | ✓ | ✓ | |
Power consumption | ✓ | ✓ | |
Memory Size | ✓ | ||
"Instant on" functionality | ✓ | ||
Small outline packages | ✓ | ✓ | |
Long-term supply | ✓ |
While FPGAs offer advantages in development speed, gate capacity, and design flexibility, ASICs provide significant benefits in unit cost, power efficiency, and supply chain security. For mature products with stable designs, the one-time NRE (Non-Recurring Engineering) cost of ASIC development can be quickly offset by reduced per-unit pricing and power consumption.
Conclusion: Securing Your Supply Chain with Epson ASICs
As semiconductor obsolescence continues to challenge industrial manufacturers, Epson's ASIC solutions provide a reliable path to long-term supply chain security. With options ranging from simple gate arrays to complex embedded memory designs, Epson can address virtually any replacement need from discontinued ICs to end-of-life programmable logic devices.
For companies facing component discontinuation challenges, Epson offers a complete replacement service with simplified design requirements—customers typically need only provide RTL code and simulation results to initiate development. With manufacturing based in Japan and a 40+ year history in ASIC design, Epson delivers both the technology and reliability needed to support industrial systems for decades to come.
