Product Overview
The Motorola MVME51105E‑2161 is a high‑performance 6U VME64x single‑board computer belonging to the MVME5100 PowerPlus‑II family, built upon PowerPC architecture (MPC7410 / 750FX CPU)mvme.net. Equipped with on‑board ECC SDRAM, flash memory, dual Ethernet, serial debug ports and dual PMC mezzanine expansion slots, it serves as main system controller for real‑time embedded racks. It features 32KB/32KB L1 cache, up to 2MB L2/L3 cache, soldered flash for boot firmware, battery‑backed NVRAM and real‑time clock, plus independent hardware watchdog for system fault recovery. It addresses typical pain‑points of legacy VME control racks: limited CPU throughput, insufficient local I/O and expansion options, lack of reliable watchdog reset for unattended critical systems. Automation system engineers, defence & industrial integrators and maintenance technicians benefit from its robust real‑time performance, PMC flexible expansion, wide OS compatibility and drop‑in spare replacement capability for existing MVME5100‑series VME chassis.
Application Scenarios
- Industrial Real‑Time VME Control Systems: Installed inside 6U VME card cages, acts as main CPU for high‑speed machinery control, semiconductor equipment and large test‑stand automation. Dual PMC slots add custom field‑bus or analog I/O mezzanine boards without consuming extra VME slots.
- Defence & Transportation Embedded Racks: Deployed for railway signalling, vehicle‑borne and rugged test‑equipment racks. Extended‑temperature capable variants sustain stable real‑time operation under fluctuating cabinet ambient conditions.
- Legacy VME System Retrofit & Spare Replacement: Direct drop‑in upgrade / spare for older MVME VME CPU racks. Reuses existing VME chassis, backplane and cabling, reducing retrofit project scope and plant downtime.
