Functional Description
MVME8100 / MVME8110 Installation and Use (6806800P25G) 78
4.8 MRAM
The MVME8100 / MVME8110 includes one MR2A16AVYS35 512 KB MRAM device to provide a non-volatile
memory, that has virtually unlimited writes (100 trillion), fast access and ten years data retention without
power. The MRAM is organized as 256Kx16 and accessible through the P5020 / P5010 local bus.
4.9 eMMC
The MVME8100 / MVME8110 contains a soldered down 8GB eMMC device connected to the P5020 / P5010
eSDHC interface. The eSDHC interface operates in four bit MMC mode and supports up to 200Mbps data
transfer for MMC card using four parallel data lines.
4.10 Processor Console Port
The MVME8100 / MVME8110 utilizes P5020 / P5010 UART1 port for the processor console interface. This
console interface can be routed to the front panel or the P2 connector using configuration switches. The
front panel port can be configured for RS-232 or RS-422/RS-485 modes. RS-232 mode supports RX, TX, RTS
and CTS signals. Only four wire full duplex RX/TX is supported in RS422/485 mode. The signaling mode is
selected through on board configuration switches. The default baud rate on the front panel serial is 9600
baud.
The physical front panel console connector is a male micro-min DB-9. A male- to -male micro-mini DB9 to
DB9 adapter cable is available under Artesyn Embedded Technologies Part Number SERIAL MINI-D (30-
W2400E01A).
4.11 Rear UART Ports
The MVME8100 / MVME8110 provides four asynchronous serial UART interfaces to the P2 RTM connector
by utilizing Exar's ST16C554 quad UART. The QUART features 16 bytes of transmit and receive FIFO's, it has
a selectable receive FIFO trigger levels and data rates of up to 1.5Mbps. Each UART has a set of registers that
provide the user with operating status and control. The QUART is a 8 bit device connected to the P5020 /
P5010 through the local bus controller. QUART port A is multiplexed with the P5020 / P5010 UART1 console
port, so that the console port can be routed to the RTM COM1 port. The mux is controlled using
configuration switches on S2.
