FANUC A20B-3300-0085 16 MB DRAM module, a compact plug-in memory daughter card that seats on the main CPU printed circuit board inside a FANUC i-series CNC or FANUC robot control rack. It supplies the processor’s volatile working DRAM. Memory Capacity: 16 MB DRAM. Edition Suffix: /03B. Unit Quantity: 1 Pc.
A20B — FANUC prefix for printed circuit boards and plug-in board assemblies.
3300 — the board family this memory card belongs to, the i-series / robot CPU board group.
0085 — the specific card, the 16 MB DRAM capacity variant. The siblings -0084 and -0086 are the same physical card at other DRAM capacities.
/03B — edition or revision suffix stamped on the board.
Brand: FANUC. Manufacturer: FANUC. Part Number: A20B-3300-0085. Base Number: A20B-3300. Series: FANUC A20B-3300 CPU board group (i-series CNC / robot control).
