Product Description
FANUC A20B-3900-0163 System Host FROM Card
The FANUC A20B-3900-0163 is a genuine, plug-in combo memory module card designed for early FANUC i Series (Model B) CNC controllers and FANUC Robotics systems. It combines Flash ROM (FROM) and Static RAM (SRAM) onto a compact dual in-line memory module (DIMM) form factor to provide high-speed data processing and system initialization data storage on the CNC master board.

Functional Overview
- Flash ROM (FROM) Purpose: The 32MB FROM segment is dedicated non-volatile storage used to host CNC control software programs, system files, and complex ladder logic configurations.
- SRAM Purpose: The 1MB SRAM segment functions as battery-backed memory utilized for parameter tracking, program execution, and fast data swap files during production.
Troubleshooting Information
Common Failure Symptom: If this component degrades or experiences data integrity faults, the CNC controller will typically trigger a RAM parity alarm on the screen.
