    The following information is for users whose applications for the MVME162 may subject it to high temperatures. The MVME162 uses commercial grade devices. Therefore, it can operate in an environment with ambient air temperatures from 0° C to 70° C. Several factors influence the ambient temperature seen by components on the MVME162.

  • Page 19: Fcc Compliance

    The following are some steps that the user can take to help make elevated- temperature operation possible: Position the MVME162 board in the chassis for maximum airflow over the component side of the board. Avoid placing boards with high power dissipation adjacent to the MVME162.

  • Page 37 Related Documentation in Chapter 1 (the MVME162 Embedded Controller Programmer’s Reference Guide provides some connection diagrams). If you intend to use the MVME162 with Port B in an EIA-530 configuration, do not install the P2 or LCP2 Adapter Board and the MVME712 series transition module. They are in- compatible with the EIA-530 interface (refer to MVME162 Serial Port 2 in Chapter 4, Functional Description).

The battery backup function for the MVME162 SRAM is provided by a Dallas DS1210S device that supports primary and secondary power sources. In the event of a main board power failure, the DS1210S checks power sources and switches to the source with the higher voltage.

  • Page 81: About The Battery

    The lifetime of the battery is very dependent on the ambient temperature of the board and the power-on duty cycle. The lithium battery supplied on the MVME162 should provide at least two years of backup time with the board powered off and with an ambient temperature of 40° C. If the power-on duty cycle is 50% (the board is powered on half of the time), the battery lifetime is four years.

    Onboard DRAM The MVME162 offers a 1MB, a 4MB, and an 8MB DRAM option. The DRAM architecture is non-interleaved for 1MB and interleaved for 4MB and 8MB. Parity protection can be enabled with interrupts or bus exception when a parity error is detected.

    MVME162 Functional Description Battery Backed Up RAM and Clock An MK48T08 RAM and clock chip is used on the MVME162. This chip provides a time-of-day clock, oscillator, crystal, power fail detection, memory write protection, 8KB of RAM, and a battery in one 28-pin package. The clock provides seconds, minutes, hours, day, date, month, and year in BCD 24-hour format.
  • Page 84 Although both ports are connected to the same Z85230 Port A, there are several differences between them: On the MVME162 front panel, Port 1 can be connected to the TxC and RxC clock signals which may be present on the DB25 connector. These connections are made via header J11 on the MVME162 board (see Figures 2-3 and 2-4 in Chapter 2).
  • Page 85 Although both ports are connected to the same Z85230 Port B, there are several considerations to keep in mind: On the MVME162 front panel, Port 2 can be connected to the TxC and RxC clock signals which may be present on the DB25 connector. These connections are made via header J12 on the MVME162 board (see Figures 2-3, 2-4, and 2-5 in Chapter 2).

    The individual configuring the system must ensure that the SCSI bus is properly terminated at both ends. The MVME162 provides sockets for SCSI bus terminators on the P2 adapter board or the LCP2 adapter board. If the SCSI bus ends at the adapter board, then termination resistors must be installed on the adapter board.

    Programmer’s Reference Guide for detailed programming information. Local Bus Timeout The MVME162 provides timeout functions in the VMEchip2 and the MCchip for the local bus. When the timer is enabled and a local bus access times out, a Transfer Error Acknowledge (TEA) signal is sent to the local bus master. The timeout value is selectable by software for 8 µsec, 64 µsec, 256 µsec, or infinity.

  • Page 89: Local Bus To Dram Cycle Times

    The EPROM/Flash cycle time is programmable from 3 to 10 bus clocks/byte (4 bytes = 12 to 40). (The actual cycle time may vary depending on the device speed.) The data transfers are 32 bits wide. Refer to the MVME162 Embedded Controller Programmer’s Reference Guide.

    SCSI bus. LAN DMA Transfers The MVME162 includes a LAN interface with DMA controller. The LAN DMA controller uses a FIFO buffer to interface the serial LAN bus to the 32-bit local bus. The FIFO buffer allows the LAN DMA controller to efficiently transfer data to the local bus.

    Serial Interconnections Proper Grounding An important subject to consider is the use of ground pins. There are two pins labeled GND. Pin 7 is the signal ground and must be connected to the distant device to complete the circuit. Pin 1 is the chassis ground, but it must be used with care.
