x📌 FANUC A20B-3300-0292 — 486 CPU Module with 32 MB DRAM
Description:
The A20B‑3300‑0240 family includes various FANUC control PCBs, and one of the key modules is the A20B-3300-0292, which is a CPU processor board used in FANUC CNC control systems.
Function & Role:
-
🧠 CPU Module: The A20B-3300-0292 is a 486-class central processor board equipped with 32 MB of DRAM memory. It serves as a main control processor within compatible FANUC CNC controller architectures, managing program execution, motion control logic, memory access, and communication with other system modules such as display, I/O, and servo interfaces.
-
🔌 Memory Onboard: The 32 MB of DRAM provides working memory for the CNC’s control software and real-time processing tasks, enabling smoother data handling and enhanced performance compared to lower-memory CPU boards.
-
⚙️ Modular Architecture: This board is part of the A20B-3300 series, which includes modular plug-in boards for CPU, display, axis control, and more in FANUC controllers.
Typical Application:
-
Used in FANUC modular CNC controllers such as early i-Series Model B / Series 16i / 18i / 21i control systems where a 486 processor-based CPU module is required.
-
Installed on a backplane within the controller cabinet alongside other system boards; it communicates with memory, I/O, motion control, and operator interface modules.
-
Serves as the processing core for interpreting CNC programs (G-code), controlling motion axes, handling I/O logic, and coordinating system tasks in machines equipped with this generation of FANUC hardware.
Important Notes:
-
This is an older generation CPU card, and while robust for its era, it is typically found in legacy control systems rather than modern FANUC versions.
-
Availability, repair options, and core exchange policies vary by supplier; some may sell refurbished units with limited support.
