☆型号：XVME-113   双高VMEbus兼容板   采用机载电池备用电路

【产品详情】

XVME-113 RAM/ROM内存模块是双高VMEbus兼容板。它可以容纳调节到12 MB的RAM, 24 MB的EPROM, 12MB的EEPROM或12mb的FLASH。

XVME-113有24个32针JEDEC袜子，逻辑上排列为两个银行。银行包含16个存储站点，第二库包含8个记忆的网站。每个银行都被设计为使用内存相同类型和速度的设备。每家银行也可以独立配置

•VMEbus地址(在标准或扩展地址空间)

•地址修饰语

•内存设备的速度和类型

XVME-113设计采用机载电池备用电路，在电源故障时为CMOS RAM器件提供电源。这个模块也提供掉电记忆保护电路时，阻止数据写入内存电压降到4.65伏以下。XVME-113也是包含一个电池支持的实时时钟和配置定量寄存器，以便读取内存类型和大小

【英文介绍】

summarize

The XVME-113 RAM/ROM memory module is a dual-height, VMEbus compatible board. It can accommodate  adjusted to 12MB of RAM, 24 MB of EPROM, 12MB of EEPROM or 12MB of FLASH.

XVME-113 has 24 32-pin JEDEC socks , logically arranged as two banks. The bank contains 16 storage sites and the second repository contains 8 memory sites. Each bank is designed to use devices of the same type and speed of memory. Each bank can also be configured independently

•VMEbus address (in standard or extended address space)

• Address modifier

• Speed and type of memory device

The XVME-113 is designed with an onboard battery backup circuit to provide power to CMOS RAM devices  in the event of a power failure. This module also provides a memory protection circuit that prevents data from being written to memory when the voltage drops below 4.65 volts. XVME-113 also contains a battery-supported real time clock and is configured with  quantitative registers for reading memory type and size

Features

●Twenty-four 32-pin memory sockets

●Full 32-bit VMEbus slave interface

●Two independently configurable memory banks

●Real Time Clock

●Read back configuration

●Battery backup for CMOS RAM devices and

Real Time Clock

●Power-down memory protection circuitry

●Completely user-configurable to allow a variety  of 32-pin memory device speeds and types to be  used
