CY62256 32K x 8 位 CMOS 静态 RAM 数据手册说明书

256K (32K x 8) Static RAMCY62256Features•High speed —55ns •Temperature Ranges —Commercial: 0°C to 70°C —Industrial: –40°C to 85°C —Automotive: –40°C to 125°C •Voltage range —4.5V – 5.5V•Low active power and standby power•Easy memory expansion with CE and OE features •TTL-compatible inputs and outputs •Automatic power-down when deselected •CMOS for optimum speed/power•Available in a Pb-free and non Pb-free standard 28-pin narrow SOIC, 28-pin TSOP-1, 28-pin Reverse TSOP-1 and 28-pin DIP packagesFunctional Description [1]The CY62256 is a high-performance CMOS static RAM organized as 32K words by 8 bits. Easy memory expansion is provided by an active LOW chip enable (CE) and active LOW output enable (OE) and Tri-state drivers. This device has an automatic power-down feature, reducing the power consumption by 99.9% when deselected.An active LOW write enable signal (WE) controls the writing/reading operation of the memory. When CE and WE inputs are both LOW, data on the eight data input/output pins (I/O 0 through I/O 7) is written into the memory location addressed by the address present on the address pins (A 0through A 14). Reading the device is accomplished by selecting the device and enabling the outputs, CE and OE active LOW,while WE remains inactive or HIGH. Under these conditions,the contents of the location addressed by the information on address pins are present on the eight data input/output pins.The input/output pins remain in a high-impedance state unless the chip is selected, outputs are enabled, and write enable (WE) is HIGH.Note:1.For best practice recommendations, please refer to the Cypress application note “System Design Guidelines” on .A 9A 8A 7A 6A 5A 4A 3A 2COLUMN DECODERR O W D E C O D E RS E N S E A M P SINPUTBUFFERPOWER DOWNWE OEI/O 0CE I/O 1I/O 2I/O 3I/O 7I/O 6I/O 5I/O 4A 10A 13A 11A 12A A 14A 1Logic Block Diagram32K × 8ARRAYPin ConfigurationsProduct PortfolioProductV CC Range (V)Speed (ns)Power DissipationOperating, I CC(mA)Standby, I SB2(µA)Min.Typ.[2]Max.Typ.[2]Max.Typ.[2]Max.CY62256L Com’l/Ind’l 4.55.05.555/702550250CY62256LL Commercial 7025500.15CY62256LL Industrial 55/7025500.110CY62256LLAutomotive5525500.11512345678910111415162019181721242322Top ViewNarrow SOIC 121325282726GNDA 6A 7A 8A 9A 10A 11A 12A 13WE V CC A 4A 3A 2A 1I/O 7I/O 6I/O 5I/O 4A 14A 5I/O 0I/O 1I/O 2CE OE A 0I/O 322232425262728125101115141312161918173420217689OEA 1A 2A 3A 4WE V CC A 5A 6A 7A 8A 9A 0CE I/O 7I/O 6I/O 5GND I/O 2I/O 1I/O 4I/O 0A 14A 10A 11A 13A 12I/O 3TSOP I Top View (not to scale)Reverse Pinout 22232425262728125101115141312161918173420217689OE A 1A 2A 3A 4WE V CC A 5A 6A 7A 8A 9A 0CE I/O 7I/O 6I/O 5GND I/O 2I/O 1I/O 4I/O 0A 14A 10A 11A 13A 12I/O 3TSOP I Top View (not to scale)12345678910111415162019181721242322Top ViewDIP 121325282726GNDA 6A 7A 8A 9A 10A 11A 12A 13WE V CC A 4A 3A 2A 1I/O 7I/O 6I/O 5I/O 4A 14A 5I/O 0I/O 1I/O 2CE OE A 0I/O 3Pin DefinitionsPin Number Type Description1–10, 21, 23–26Input A 0–A 14.

1980命名法螺环化合物命名

1980命名法螺环化合物命名

1980命名法螺环化合物命名1980年命名法是一种有机化学中常用的命名方式,适用于螺环化合物的命名。

螺环化合物是由两个或多个环嵌套而成的化合物,通常具有复杂的结构和特殊的性质。

在1980年命名法中,首先从化合物的最长链开始命名,然后按照以下步骤进行命名。

第一步,确定最长链最长链是指螺环化合物中,由所有碳原子组成的链状结构的部分。

在确定最长链时,通常需要优先考虑含有双键、三键或官能团的碳原子。

最长链的碳原子数即为命名中的前缀。

第二步,标记官能团和侧链在最长链的命名中,官能团和侧链需要通过指定位置的方式标记出来。

如果存在多个相同类型的官能团或侧链,可以使用多个相同的位置号进行标记。

第三步,命名前缀根据最长链的碳原子数,选择合适的前缀进行命名。

常用的前缀有"nor"、"sec"、"t"等。

在选择前缀时,应优先考虑碳原子数更多的情况。

第四步,标识螺环系统如果螺环系统是化合物中的一个主要部分,需要在命名中标识出来。

螺环系统的命名一般以"spiro"结构为前缀,并在后面跟随一个数字,表示螺环系统的大小。

第五步,确定立体化学信息如果螺环化合物中含有立体中心或立体异构体,需要在命名中指定其立体化学信息。

常用的表示方式有"D-"、"L-"、"R-"、"S-"等。

综上所述,1980年命名法螺环化合物的命名步骤为:确定最长链、标记官能团和侧链、命名前缀、标识螺环系统、确定立体化学信息。

下面以一个具体的例子来说明该命名法的应用。

假设有一个螺环化合物,结构如下:HH3CCH3 H3CC\CH2C-CH2/H3CC CH3CH2H首先确定最长链,从左下方的碳开始,包括左上方的官能团和右下方的碳原子,最长链有8个碳原子。

然后标记官能团和侧链,左上角的官能团是甲基(CH3),右下角的官能团是甲基(CH3)。

六氯苯分解温度

六氯苯分解温度

六氯苯分解温度
六氯苯是一种有机物,是一种具有毒性的污染物。

为了安全处理
处理六氯苯,需要知道它的分解温度,本文将围绕六氯苯分解温度为
大家进行详细的介绍。

第一步,了解六氯苯的性质
六氯苯是一种带有六个氯原子的有机物,化学式为C6HCl6,常温下为
无色晶体,不易溶于水。

高温下,六氯苯可以分解成为一些比较稳定
的单质或其它开放环状化合物。

第二步,分析六氯苯分解的原因
六氯苯分解的过程中,化合物与热源或高温环境接触,使得化学键断裂,从而导致分子的解离。

在分解过程中,热量大部分被消耗用于打
破化学键。

第三步,测定六氯苯的分解温度
测定六氯苯的分解温度需要使用实验室设备,不同的设备对结果的影
响也不同。

通常情况下,通过使用热重分析法可以获得六氯苯的分解
温度。

在热重分析实验中,一个固体样品在恒定的热环境下加热,并
且需要不断测量样品重量的变化。

当六氯苯开始经历分解反应时,样
品的重量会出现明显的下降,这时就可以得到六氯苯的分解温度了。

总的来说,六氯苯分解温度是一个很重要的物理参数,它有助于
我们合理处理六氯苯及其废物,避免对环境和人体的污染,促进环保
事业的发展。

当需要进行处理六氯苯的工作时,务必要严格控制温度,以避免对环境产生危害。

摘要:An optimization process for optimizing inputs data relating to a function of a plurality of input-signals for which it is desired to find output values which give an optimum value of the function. Such output values are found by performing a plurality of cycles to reach a convergence, each of which cycles includes: (a) providing an old current value of each input signal, (b) selecting a test value of one or more input signals; (c) generating the function from the selected test values; and (d) selecting a new current value in dependence upon the relationship between the value of the function for the test value and the value of the function for the old current value. The test values include values close to old current values so as to move the input signal towards a local convergence for the output values. The finding of output values is adapted to perform the cycles such that in some but not all of the cycles, the test value of one or more input signals is selected to lie remotely within the range of the input signal to the old current value, so as to move the input signal towards a global convergence prior to completion of the local convergence.

BASIC Stamp图1:BASIC Stamp 2说起控制器,首先想到的就是BASIC Stamp,也是最早期的控制器了。

BASIC Stamp(有时也称BASIC Stamp Module)是由美国Parallax公司自1992年起推出的一种微控制器,此种微控制器与其他微控制器不同的地方在于:微控制器(BASIC Stamp)中的ROM内存内建了一套小型、特有的BASIC(培基)编程语言直译器(Interpreter)——PBASIC。

有了PBASIC后,想开发、撰写微控器应用的设计者,只要学会、具备BASIC编程语言的撰写能力,就能够用其开发出嵌入式系统所用的控制程序,大幅降低了嵌入式设计的技能学习门槛,也因此BASIC Stamp在电子电机的玩家群中相当受欢迎。

当我们应用BASIC Stamp控制器时该如何选择呢?我相信下面的这个对比图片一定会给你提供帮助。

它适用于爱好者、艺术家、设计师和对于"互动"有兴趣的朋友们。

它是一个基于开放原始码的软硬件平台,构建于开放原始码simple I/O介面版,并且具有使用类似Java、C语言的Processing/Wiring开发环境。

高考作文跑题的6大陷阱,80%的考生都被带跑了
作文,是语文科目中重要的组成部分,也是学生最需要灵活掌握、发挥的一部分内容。

同学们在写作中容易犯的错误之一就是作文跑题,这也会成为通篇文章的最大硬伤,那么我们在写作时该如何避免跑题呢?
作文跑题的类型
1.写作文前不审题,对作文要求理解不够深刻
有的学生只看一眼作文题目,不看具体要求就开始写作文,结果因不符合要求而跑题。

比如:半命题作文题目为:我的XXX,要求以写人为主,但很多学生没有看清要求,写的是有关动物的作文,那么文章无论写多好都没有用。

再比如:有篇作文要求写一个传统节日,传统节日即具有民族特色的节日,也就是中华民族的传统节日,可有的同学却写六一儿童节、三八妇女节、植树节。

不是这些同学没有审题,而是因为他们审题不够细致从而导致作文跑题。

建议:
审清文体。

就是要明白写作文是写人,还是记事;是写景,还是状物;是日记,还是书信;是实用文,还是想像文……
写人,是写一个人,还是写两个人或是写一群人;叙事,是叙述一件事,还是叙两件或叙几件事,审题时都要弄清楚。

文体如果弄不清楚,作文就会跑题,也就必然导致全文失败。

2.题目与文章主题不符,没审清重点
例如,有一篇命题作文,它的题目是“我和好朋友”,在作文中我们应该强调的就是我们之间的故事,强调的是我们之间曾经发生什么,我们的
关系如何等等。

但如果文章着重强调我的好朋友他是什么样的人,他有什么故事等等,这样就不符合文章标题了,导致整篇文章立意不明。

建议:
为了避免这个问题,我们在拿到作文题目的时候要先审清题意(包括审清文章标题和审清作文的提示语),先弄清题目让我们写什么,再进行下一步。

关于审清重点,也就是“题眼”,是命题中关系到主题的关键词语,它是题目的核心,把握住了“题眼”,也就把握住了作文的重点。

同是叙述一件事,《一件难忘的事》和《一件童年趣事》这两个文题的写作重点是不同的:《一件难忘的事》的写作重点是突出这件事的“难忘”所在,或高兴、或悲伤、或悔恨、或激动,要把难忘之处描绘出来,能激起读者同悲同喜的情感,就抓住了主题;而《一件童年趣事》的写作重点,则是所叙的趣事必须发生在童年,要把趣之所在描绘出来,这样写出来的文章才更符合主题。

因此说,找准了文题所要写的重点,也就把握住了文章所要表达的中心,选材也就有了范围,组织材料也就有了目标。

3.文中的议论、抒情句与所叙述的事件不符
这是很多同学在写作中会犯的错误。

在文章的开头和结尾,同学们会有意识地加入抒情和议论,但是这些抒情和议论与所叙述的事件传递出的中心思想并不相符。

使文章显得首尾不搭,主题跑偏。

造成这种问题的原因主要是同学们为了叙事而叙事。

可能是由于同学们手头素材较少,想不出符合文章主题的事件,也有可能是同学们刻意抒情、议论而没有考虑文章的主题统一。

建议:
为了解决这种问题,同学们就需要在开始动笔写作文之前列提纲。

先明确作文的主题是什么,然后根据主题选择合适的素材和事件。

只有这两点确定了,再进行议论和抒情,才能让整篇文章的主题统一明确。

4.叙事篇幅过大,没有点明主题的句子
这也是很多写作程度比较好的同学常犯的错误,非常遗憾。

同学们可能用了很长的篇幅去叙事,进行细节描写、人物描写等等,让叙事非常生动细致,但遗憾的是,叙事部分没有突出表现文章的主题,导致整篇文章主题不明确、不突出。

建议:
建议大家在叙事过程中有意识地扣题、点题。

一方面提醒自己不要跑题,另一方面在叙事过程中不断扣题,能够突出文章的主题,使文章主题鲜明。

如何在叙事中扣题呢?我们可以采用夹叙夹议的办法,在叙事中夹杂议论和抒情,这样就能很好地体现文章中心。

5.详略不得当,不能体现作文主题
同学们在写作中有时候会写跑题了,却不自知,这是为什么呢?
因为同学们叙事详略不当。

比如在让同学们写读后感的时候,800字的作文,很多同学用了400字去介绍这本书的作者、这本书的内容、这本书是怎么来的等等。

这就几乎注定了同学们的作文一定会跑题,因为首先在篇幅上设置的就不合理。

建议:
这里也是建议大家先写作文提纲,确定好文章的每个部分大约要占多少字,先对篇幅有个整体的把控,至少整篇文章看起来是能很好地体现主题的。

6.积累的素材少,写作文时头脑不够灵活
在写作文时写着写着就没内容可写了,就乱凑字数,这很明显是作文素材积累不够。

也有的学生不会写作文,提起笔来就觉得没什么可写的,
往往是老师教过的作文他就背下来,老师没教的作文就不会写。

建议:
这样的同学除了多读书多积累词汇,平时多观察以外,还要灵活运用以往写过的作文。

写作建议
1.在审题过程中,要特别注意有一类题目范围比较广,可写的内容比
较多,各有侧重点,同学们既要认真推敲题意,又要打开思路,展开联想,把文章写活。

比如《校园的早晨》,可以描写早晨校园里师生锻炼身体的火热场面,也可以写同学们刻苦学习的动人情景,还可以摄取若干小镜头、小片段,表现同学们新的道德风尚,或者是热情歌颂园丁为培育新苗不辞辛苦……
总之,审题的时候,既要准确地理解题意,紧扣题目来写,又不要把思路限制得很死,避免千篇一律。

2.在审清题目之后,写作文之前最好列一个提纲,不必太详细只要有
大体思路即可。

有了思路之后,再将自己所能想到的跟主题有关的例子、名言之类的东西列一下,最后开始写就一般就没问题了。

所以,在写文章之前一定要审好题,认真分析写作要求,按要求去写作文,灵活运用平时积累的字、词、句、段、篇,不要生搬硬套。

这样在写作中就能“随心所欲不逾矩,下笔千言不走题。


3.多阅读时事新闻、报刊杂志、书籍,注意观察生活,多思考,多表
达,平时注意积累一些对事物的感想,这样对锻炼思维、答题、写作都有好处。

建立素材库,把收集的素材分门别类归纳起来,对应不同的主题,熟悉所积累的素材,这样写作时才能信手拈来,运用自如。
