HAC319AEV1 HIEE300771R1工控自动化卡件
用户可以采取一些步骤来帮助实现高温操作：1。将MVME162FX嵌入式控制器放置在机箱中，以使电路板组件侧的气流达到最大。2.避免将高功耗板放置在控制器附近。3.仅使用低功耗工业封装模块。IP模块的首选位置是位置a（J2和J3）和位置d（J18和J19）。1-8计算机组文献中心网站板级硬件说明1 EMC合规性MVME162FX控制器是板级产品，旨在用于标准VME应用程序。因此，系统集成商有责任满足与给定应用相关的监管指南。控制器已在具有代表性的底盘上进行了CE B级EMC认证测试。EMC合规性是在以下条件下实现的：1。所有外部I/O端口上的屏蔽电缆。2.通过与导电模块前面板结合的金属外壳连接器连接到接地的电缆屏蔽。3.导电底盘导轨接地。这提供了将屏蔽连接到接地的路径。4.前面板螺钉正确拧紧。对于最小射频发射，必须满足上述条件。否则，可能会影响包含模块的设备的EMC合规性。手册术语本手册使用数据和地址参数的特殊符号约定。该参数的前缀是一个字符，该字符标识数字格式如下：例如，“12”是十进制数字12，“$12”是十进制数18。除非另有规定，否则所有地址引用均采用十六进制表示法。$Dollar指定十六进制字符%Percent指定二进制数和安培数，并指定十进制数简介http://www.mcg.mot.com/literature1-9 1信号名称后的星号（*）表示信号为低电平时信号为“真”或“有效”。边缘有效信号的信号名称后面的星号（*）表示由该信号启动的动作发生在从高到低的转变上。在本手册中，术语断言和否定用于指定将信号强制到特定状态。特别地，“断言”和“断言”指的是活动的或真实的信号；“否定”和“否定”是指无效或错误的信号。这些术语的使用与它们所代表的电压电平（高或低）无关。数据和地址大小定义如下：❏ 一个字节是八位，编号为0到7，位0是最低有效位。❏ 两个字节是16位，编号为0到15，位0是最低有效位。对于MVME162FX和其他CISC模块，这被称为aword。❏ 四字节是32位，编号为0到31，位0是最低有效位。对于MVME162FX和其他CISC模块，这被称为alongword。本文档中广泛使用了术语控制位、状态位、真和假。术语控制位用于描述寄存器中可以在软件控制下设置和清除的位。术语true用于表示一个位处于启用其控制的功能的状态。术语false用于指示该位处于禁用其控制的功能的状态。在所有表中，术语0和1用于描述应写入位的实际值，或读取时产生的值。术语状态位用于描述寄存器中反映特定条件的位。软件可以读取状态位，以确定操作或异常条件。1-10计算机组文献中心网站板级硬件描述1框图图1-1是MVME162FX嵌入式控制器设计的一般框图。图1-1：。MVME162FX闪存Z85230 SCC串行IO MK48T08 BBRAM&CLOCK 53C710 SCSI DRAM 82596CA LAN ETHERNET MC2芯片VMEbus VMEchip2 1559 9412 IP2芯片SRAM PROM SOCKET MC68040或MC68LC040功能描述http://www.mcg.mot.com/literature 1-11 1
some steps that the user can take to help make elevated temperature operation possible: 1. Position the MVME162FX Embedded Controller in the chassis for maximum air flow over the component side of the board. 2. Avoid placing boards with high power dissipation adjacent to the controller. 3. Use low power Industry Pack modules only. The preferred locations for IP modules are position a (J2 and J3) and position d (J18 and J19). 1-8 Computer Group Literature Center Web Site Board Level Hardware Description 1 EMC Compliance The MVME162FX controller is a board-level product and is meant to be used in standard VME applications. As such, it is the responsibility of system integrators to meet the regulatory guidelines pertaining to a given application. The controller has been tested in a representative chassis for CE class B EMC certification. EMC compliance was achieved under the following conditions: 1. Shielded cables on all external I/O ports. 2. Cable shields connected to earth ground via metal shell connectors bonded to a conductive module front panel. 3. Conductive chassis rails connected to earth ground. This provides the path for connecting shields to earth ground. 4. Front panel screws properly tightened. For minimum RF emissions, it is essential that the conditions above be implemented. Failure to do so, could compromise the EMC compliance of the equipment containing the module. Manual Terminology This manual utilizes a special symbolic convention for data and address parameters. The parameter is prefixed with a character which identifies the numeric format as follows: For example, "12" is the decimal number twelve, and "$12" is the decimal number eighteen. Unless otherwise specified, all address references are in hexadecimal notation. $ Dollar Specifies a hexadecimal character % Percent Specifies a binary number & Ampersand Specifies a decimal number Introduction http://www.mcg.mot.com/literature 1-9 1 An asterisk (*) following the signal name for signals which are level significant denotes that the signal is “true” or “valid” when the signal is low. An asterisk (*) following the signal name for signals which are edge significant denotes that the actions initiated by that signal occur on a high to low transition. In this manual, the terms assertion and negation are used to specify forcing a signal to a particular state. In particular, “assertion” and “assert” refer to a signal that is active or true; “negation” and “negate” refer to a signal that is inactive or false. These terms are used independently of the voltage level (high or low) that they represent. Data and address sizes are defined as follows: ❏ A byte is eight bits, numbered 0 through 7, with bit 0 being the least significant. ❏ A two-byte is 16 bits, numbered 0 through 15, with bit 0 being the least significant. For the MVME162FX and other CISC modules, this is refered to as aword. ❏ A four-byte is 32 bits, numbered 0 through 31, with bit 0 being the least significant. For the MVME162FX and other CISC modules, this is refered to as alongword. The terms control bit, status bit, true, and false are used extensively in this document. The term control bit is used to describe a bit in a register that can be set and cleared under software control. The term true is used to indicate that a bit is in the state that enables the function it controls. The term false is used to indicate that the bit is in the state that disables the function it controls. In all tables, the terms 0 and 1 are used to describe the actual value that should be written to the bit, or the value that it yields when read. The term status bit is used to describe a bit in a register that reflects a specific condition. The status bit can be read by software to determine operational or exception conditions. 1-10 Computer Group Literature Center Web Site Board Level Hardware Description 1 Block Diagram Figure 1-1 is a general block diagram of the MVME162FX Embedded Controller’s design.
