Motorola MVME6100-0173 Voltage and Current

Backplane input voltage: +5V ±5%, +12V, -12V, fed through VME64x backplane P1/P2 connectors.

On-board DC-DC regulators convert the incoming +5V supply into internal working voltages including +3.3V, +2.5V, +1.8V and processor core voltage.

+5V input current (PMC/IPMC modules not fitted): typical 8.4A, maximum 10.2A.

+5V input current with MVME761 extension module installed: typical 9.2A, maximum 11.2A.

+12V and -12V supply only low auxiliary current for peripheral circuitry.

Extra current will be consumed upon installation of PMC or IPMC expansion cards; IPMC modules draw up to 0.5A on +5V rail and up to 0.75A on +3.3V rail.

Typical overall power consumption stands between 42W and 51W for standard hardware configuration.

Motorola MVME6100-0173 Working Principle

This VME64x single-board computer adopts the MPC7457 PowerPC processor and functions as the primary control component for VME-based industrial and embedded control systems. Power is supplied through the VME backplane, while onboard DC-DC converters generate multiple internal core voltages to power the CPU, memory modules and peripheral integrated circuits.

The MPC7457 processor runs system firmware and user application software. Built-in L1/L2 cache plus external L3 cache optimize data access efficiency. The MV64360 system controller serves as the main host bridge, governing data traffic among the CPU, DDR-ECC main memory, flash memory and local PCI-X buses. DDR-ECC memory delivers real-time error detection and correction to support stable long-term continuous operation. Flash memory holds the MOTLoad boot firmware, system configuration parameters and application program images.

The Tsi148 interface chip implements VME64x bus communication. It supports high-speed 2eSST transmission rates up to 320 MB/s while retaining backward compatibility with legacy VME protocols. It maps local memory address ranges to the VME backplane address space for data communication with other VME slave modules, and processes VME interrupt distribution as well as bus arbitration tasks.

Two independent PCI-X channels extend system capability. One channel interfaces with the Tsi148 VME controller, and the second channel drives dual PMC-X mezzanine connectors for peripheral expansion cards. On-board peripherals such as dual gigabit Ethernet ports, UART serial interfaces, real-time clock and watchdog timer are connected to the PCI-X bus and managed by the system controller.

Upon power-up, the MOTLoad boot firmware performs hardware initialization, self-diagnostic checks and memory mapping setup. It loads the target operating system or user application from flash, network resources or PMC storage media. The integrated interrupt controller routes interrupt events originating from the VME bus, PMC modules, Ethernet and serial peripherals to the processor for event processing.

Configurable as a VME system controller, this board handles VME bus reset, bus arbitration and system timing management. The watchdog circuit supervises software execution and initiates a system reset in case of program runaway to improve overall system robustness. DIP status switches and LED indicators offer hardware configuration options and runtime diagnostic feedback for field maintenance work.
