The XVME-601 is a single-high (3U) VMEbus-compatible Processor Module originally manufactured by Xycom (later associated with Acromag and Xembedded). It is primarily designed as a robust computing platform for industrial control systems (ICS) and human-machine interfaces (HMI).Core

Technical Specifications

1. Processor: Uses an internal 10 MHz Motorola 68000 or 68010 CPU.
2. Form Factor: 3U single-high VME board (sometimes outfitted with a 6U front panel kit for specific chassis fitments).
3. On-board Memory:
4. 512 KB of local DRAM.
5. Two byte-wide memory sockets supporting up to 128 KB of local EPROM.
6. The CPU accesses both DRAM and EPROM directly with zero wait states.
7. I/O and Connectivity:
8. Two RS-232C serial ports.
9. A 16-bit programmable timer managed via an on-board 68681 Dual Asynchronous Receiver/Transmitter (DUART).
10. System Diagnostics: Features three front-panel LEDs to visually convey CPU HALT status and diagnostic PASS/FAIL status (integrated with the 601 firmware monitor).
11. VMEbus Utilities: Provides system management utilities including SYSCLK, SYSRESET, a single-level arbiter, a Bus Timer, and an IACK Daisy Chain Driver.
