MVME162-212

The MVME162LX 200/300 Series is based on the MC68040 or MC68LC040 microprocessor. The -LC040, a subset of the -040 line for low cost embedded controller applications, is the -040 without a built-in math coprocessor (FPU). The MVME162LX 200/300 Series is available in various versions with the features listed in Table 1-1 on page 1-5.

The I/O on the MVME162LX 200/300 Series is routed through front panel connectors, and the board uses no transition boards. These characteristics also apply to the other models of the 162LX board, those in the 700/800 Series.

The I/O connection for the serial ports on the MVME162LX is provided by four RJ45 front panel I/O connectors. (For more information on the Serial Communications Interface see the Hardware Description chapter of the MVME162LX Embedded Controller Installation and Use manual, the 200/300 Series version.)

Various versions of the MVME162LX 200/300 Series have either 1 or 4MB of parity-protected DRAM, or 4, 8, 16, or 32MB of ECC-protected DRAM on a mezzanine board. (Note the CAUTION on a Parity DRAM- related issue in the Features Summary; see Table 1-1 on page 1-5; note also that, in the 700/800 Series, parity protection for DRAM is unsupported). The boards also come with either 128 KB of SRAM (with battery backup) or 2 MB SRAM on a mezzanine board (with battery backup). The MVME162LX 200/300 Series also comes with a time of day clock (with battery backup), an optional LAN Ethernet transceiver interface, four serial connections with EIA-232-D interface, six tick timers with watchdog timer(s), four EPROM sockets, 1 MB Flash memory (one Flash device), two IndustryPack (IP) interfaces, optional SCSI bus interface with DMA, and optional VMEbus interface (local bus to VMEbus/VMEbus to local bus, with A16/A24/A32, D8/D16/D32 bus widths and a VMEbus system controller). Note that currently one model comes with no VMEbus to provide an additional option.
