CPLD MAX? 系列 600 門(mén) 32 宏電池 0.8um 技術(shù) 5V 28 引腳窗口 CDIP
CY7C344具有28引腳，300 mil DIP或加窗j引腳陶瓷芯片載體(HLCC)，代表了該尺寸中密度最大的EPLD。8個(gè)專(zhuān)用輸入和16個(gè)雙向I/O引腳通信到一個(gè)邏輯陣列塊。在CY7C344 LAB中有32個(gè)宏細(xì)胞和64個(gè)膨脹產(chǎn)物項(xiàng)。當(dāng)使用I/O宏單元格作為輸入時(shí)，使用兩個(gè)擴(kuò)展器來(lái)創(chuàng)建輸入路徑。即使所有的I/O引腳都由宏單元寄存器驅(qū)動(dòng)，仍然有16個(gè)“埋藏”寄存器可用。所有輸入、宏單元和I/O引腳在LAB內(nèi)相互連接。
CY7C344的速度和密度使其成為所有類(lèi)型應(yīng)用的自然選擇。僅使用這一個(gè)器件，設(shè)計(jì)人員就可以實(shí)現(xiàn)復(fù)雜的狀態(tài)機(jī)、注冊(cè)邏輯和組合“粘合”邏輯，而無(wú)需使用多個(gè)芯片。這種架構(gòu)靈活性允許CY7C344取代多芯片TTL解決方案，無(wú)論它們是同步的、異步的、組合的還是三者兼而有之。
