The FANUC A20B-2000-0170 is a 32-bit main motherboard/master control printed circuit board (PCB) manufactured in Japan. It serves as the primary processing hub for several popular legacy FANUC Series 0-C and 0-F digital CNC systems. Technical Specifications

1. Architecture: 32-bit processing engine featuring a "split architecture".
2. Data Management: Utilizes shared memory processing across a backplane to distribute workloads efficiently between its peripheral boards.
3. Standard Framework: At its base level, it connects directly with memory, axis, and I/O modules utilizing a PC cassette configuration. Large scale deployments can expand to connect with a dedicated graphics processor or a PMC-M module.
