Functional Description
MVME51005E Single Board Computer Installation and Use (6806800A38D) 71
4.3.2 Processor
The MVME5100 incorporates a BGA foot print that supports both the MCP7410 and the
MCP75x processors. The maximum external processor bus speed is 100 MHz.
Note: The MCP7410 is configured to operate only with the PowerPC 60xbus interface.
4.3.3 System Memory Controller and PCI Host Bridge
The on-board Hawk ASIC provides the bridge function between the processor’s bus and the PCI
bus. It provides 32-bit addressing and 64-bit data; however, 64-bit addressing (dual address
cycle) is not supported. The ASIC also supports various processor external bus frequencies up
to100 MHz.
There are four programmable map decoders for each direction to provide flexible address
mappings between the processor and the PCI bus. The ASIC also provides an Multi-Processor
Interrupt Controller (MPIC) to handle various interrupt sources. They are: four MPIC timer
interrupts, interrupts from all PCI devices and two software interrupts.
4.3.4 Memory
The following subsections describe various memory capabilities on the MVME5100 including
Flash memory and ECC SDRAM memory.
4.3.4.1 Flash Memory
The MVME5100 contains two banks of Flash memory. Bank B consists of two 32-pin devices
which can be populated with 1MB of Flash memory (only 8-bit writes are supported for this
bank). Refer to the application note following for more write-protect information on this
product.
Bank A has 4 16-bit Smart Voltage FLASH SMT devices. With 32Mbit flash devices, the flash
memory size is 16MB. Note that only 32-bit writes are supported for this bank of flash memory.
Application Note: For Am29DL322C or Am29DL323C, 32Megabit (4M x 8-Bit/2M x 16-bit)
CMOS 3.0 Volt-only Flash Memory.
