Product Introduction
Motorola MVME215-1 delivers MC68020 processing at 12.5 MHz on the VMEbus with 512 KB–4 MB local DRAM and dual serial ports for embedded control applications. It acts as A24/D16 master/slave on the VME backplane while handling local I/O through EIA-232 ports, Centronics parallel, and optional Ethernet for network connectivity.
Target uses include RTU masters, telecom node controllers, and test equipment where VME64 compatibility meets legacy 68000-family code requirements. Four ROM sockets hold boot/debug firmware; zero-wait-state RAM supports real-time tasks at full CPU speed.
Frequently Asked Questions
Q: Does the MVME215-1 support hot-swapping in a VME chassis?
A: VMEbus does not support live module changes; power down the crate completely before installing or removing the MVME215-1. At 3.5 A @ 5 VDC maximum draw, it affects crate power budget significantly—measure +5 V/+12 V/−12 V rails post-install and confirm no bus arbitration conflicts before booting the system.
Q: Is the MVME215-1 obsolete, and what are the replacement paths?
A: Long obsolete from Motorola (now NXP); equivalent-era boards include MVME260/270 series with 68040 upgrades or PowerPC successors like MVME5100. Code porting required from 68020 to PPC ISA; VME64 SBCs from concurrent vendors (Force, Radstone) offer drop-in pinouts but different firmware environments. Stock spares only for legacy systems.
Q: Will I lose my VME application code or configuration when replacing the board?
A: Application runs from ROM/DRAM or VME shared memory; board swap does not erase code unless DRAM lacks battery backup. Most common mistake is forgetting ROM contents—back up all four EPROMs with a programmer, document jumper settings (wait states, bus timing), and verify DRAM size before swapping to avoid addressing faults.
Q: Are these MVME215-1 boards factory-new or refurbished when sold as surplus?
A: Available stock represents New Surplus from decommissioned military/industrial VME crates, not active Motorola production. Expect clean P1/P2 gold fingers, original Motorola labeling, and intact ROM sockets for “New Original” claims; socket wear or pencil-marked jumpers indicate field use—require 24-hour burn-in test at full load.
