KOKUSAI KOMS-A2 CXP-544A CPU Board – Central Processing Unit | KOMS-A2 Series Platform
Engineering Background
KOKUSAI Electric (formerly Hitachi Kokusai Electric) is a globally recognized manufacturer of semiconductor diffusion furnaces and thermal processing equipment. The KOMS-A2 platform represents the company’s mature generation of process control architecture, widely deployed in 200mm and 300mm wafer fabrication facilities across Asia, Europe, and North America. The CXP-544A is the central CPU board within this control system, responsible for real-time process sequencing, recipe management, and inter-module communication.
Product Positioning
The CXP-544A CPU Board is a mission-critical spare part for facilities operating KOKUSAI KOMS-A2 controlled diffusion furnaces, oxidation systems, and LPCVD equipment. Procurement engineers and maintenance teams rely on this module to minimize unplanned downtime and maintain process continuity. Konmask.com supplies verified, tested units sourced from decommissioned systems and authorized surplus channels, with full traceability documentation available upon request.

Engineering Advantages
- Drop-in Replacement: Direct form-fit-function replacement for failed or degraded CXP-544A units in KOMS-A2 systems — no firmware modification required in most configurations.
- Verified Functionality: Each unit undergoes bench-level power-on and communication verification prior to shipment.
- Traceability: Serial number and revision level documented; traceability records available upon request for ISO-compliant facilities.
- Reduced Lead Time: In-stock availability eliminates the 12–26 week OEM lead time typical for legacy KOKUSAI spare parts.
- Global Logistics: Ships worldwide with DHL Express, FedEx, or freight forwarding; export documentation and commercial invoice included.
System Architecture & Signal Flow
Within the KOMS-A2 control architecture, the CXP-544A CPU Board serves as the master controller on the system backplane. It interfaces with I/O expansion boards, temperature control modules, and the host computer via the KOMS-A2 proprietary communication bus. The CPU board executes process recipes stored in non-volatile memory, manages alarm logic, and coordinates real-time feedback from thermocouples and mass flow controllers. Replacement of this board restores full system control authority without requiring replacement of peripheral I/O or sensor modules.

Technical FAQ
Q: Is the CXP-544A compatible with all KOMS-A2 system revisions?
A: The CXP-544A is compatible with the majority of KOMS-A2 platform configurations. Please provide your system model and software revision for compatibility confirmation before ordering.
Q: Does the board require re-initialization or recipe reload after replacement?
A: In most cases, process recipes are stored on the host computer or a separate memory module. The replacement CPU board will require system initialization per the KOMS-A2 maintenance manual. We can provide guidance on this procedure.
Q: Can you supply multiple units for a planned maintenance program?
A: Yes. We maintain stock of multiple units and can fulfill blanket orders. Contact us for volume pricing and consignment options.
Q: What is the typical shipping time to Taiwan, South Korea, or the USA?
A: DHL Express typically delivers within 3–5 business days to major semiconductor hubs in Asia and North America. Freight forwarding options are available for larger orders.
Q: Is an export license required?
A: This product is a commercial spare part and does not fall under ITAR or EAR controlled categories in most jurisdictions. However, buyers are responsible for compliance with their local import regulations.
