描述

PC-E984-258

PIC單片機(jī)集成了多種混合信號(hào)外設(shè)，這些小型PIC單片機(jī)沿襲了傳統(tǒng)的模擬外設(shè)，包括帶有Flip-Flop觸發(fā)輸出模式的比較器，該比較器可設(shè)置成遲滯比較器，其功能與555定時(shí)器電路類似。片上具有模數(shù)轉(zhuǎn)換器（ADC）以及超低功耗喚醒功能，利用此功能可延長(zhǎng)外部電池的使用壽命。除此之外，也新增了一些混合信號(hào)的外設(shè)，例如帶有自動(dòng)關(guān)斷功能的數(shù)字脈寬調(diào)制器，這在某些開關(guān)電源中非常重要。當(dāng)特定的外部事件（如過壓或過流）發(fā)生時(shí)，PWM輸出將被禁止，從而起到有效保護(hù)的作用。而利用模擬PWM外設(shè)，用戶可以產(chǎn)生多相PWM信號(hào)，而使用電壓比較器還可以改變脈沖寬度。片上的并聯(lián)穩(wěn)壓器可以輸出5V恒定電壓，為單片機(jī)或其它負(fù)載供電。

晶體管體積和能耗的大幅下降，雖然使噪聲容限明顯減小，但也對(duì)極深亞微米芯片的可靠性帶來了影響。因此，為提高良率，改善運(yùn)行的可靠性，需采用ECC和冗余技術(shù)。
? ? 由于現(xiàn)在SoC的位元數(shù)已十分龐大，因此，嵌入式存儲(chǔ)器便成為了決定SoC良率的最重要因素。在提高存儲(chǔ)器良率方面，由于可減少批量生產(chǎn)時(shí)間，控制測(cè)試與修復(fù)成本，因此專有測(cè)試與修復(fù)資源具有重要作用。采用一次可編程存儲(chǔ)技術(shù)制造的存儲(chǔ)器IP，在芯片制造完成后，發(fā)生存儲(chǔ)信息失效時(shí)，其內(nèi)置自修復(fù)功能便可對(duì)存儲(chǔ)器陣列進(jìn)行修復(fù)。理想情況下，為在生產(chǎn)測(cè)試過程中，快速進(jìn)行修復(fù)編程，存儲(chǔ)器編譯器的修復(fù)功能需與硅片測(cè)試工具緊密集成。
? ? 對(duì)于設(shè)計(jì)師來說極其重要的是，可根據(jù)需要選擇由晶圓代工企業(yè)制造位單元，或者進(jìn)行自我設(shè)計(jì)。需進(jìn)行定制設(shè)計(jì)時(shí)，與理解定制設(shè)計(jì)且可為各流程節(jié)點(diǎn)提供硅片數(shù)據(jù)的嵌入式存儲(chǔ)器供應(yīng)商進(jìn)行合作，具有極大的幫助作用。有了先進(jìn)的設(shè)計(jì)技術(shù)，即使不需要額外的掩膜和流程修正，亦可最大限度地提高良率和可靠性。

選擇深圳長(zhǎng)欣，選擇放心，售后無憂大量現(xiàn)貨，當(dāng)天順豐發(fā)貨！
主營(yíng)：本特利，英維思，伍德沃德，?？怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂，ACSO，力士樂等各大品牌的DCS系統(tǒng)配件，機(jī)器人系統(tǒng)配件，大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”（不管能不能看懂，先了解個(gè)大概，以便學(xué)習(xí)編程時(shí)查找）；
2、由位控邏輯入手，逐漸增加定時(shí)、計(jì)數(shù)等條件，把或、與、非關(guān)系理順；
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換；
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解（最好是有個(gè)物理回路驗(yàn)證，比如變頻器+電機(jī)+測(cè)速傳感器）；
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制（盡量避免跳轉(zhuǎn)，非跳不可時(shí)也是跳的越近越好）；
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列，GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌，由于PLC的基本框架大同小異，學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡(jiǎn)單了。
