STC89C54RD+

STC89系列單片機(jī); ? 增強(qiáng)型8051單片機(jī)，6時鐘/機(jī)器周期和12時鐘/機(jī)器周期可任意選擇，指令代碼完全兼容傳統(tǒng)8051\r\n? 工作電壓：5.5V - 3.3V (5V單片機(jī)) / 3.8V - 2.0V (3V單片機(jī))\r\n? 工作頻率范圍：0～40MHz，相當(dāng)于普通8051的 0～80MHz，實際工作頻率可達(dá)48MHz.\r\n? 用戶應(yīng)用程序空間：4K / 8K / 13K / 16K / 32K / 64K字節(jié)\r\n? 片上集成1280字節(jié)或512字節(jié)RAM\r\n? 通用I/O口(35/39個)，復(fù)位后為：P1/P2/P3/P4是準(zhǔn)雙向口/弱上拉(普通8051傳統(tǒng)I/O口)；P0口是開漏輸出，作為總線擴(kuò)展用時，不用加上拉電阻，作為I/O口用時，需加上拉電阻。\r\n? ISP（在系統(tǒng)可編程）/ IAP（在應(yīng)用可編程），無需專用編程器，無需專用仿真器 可通過串口（RxD/P3.0, TxD/P3.1）直接下載用戶程序，數(shù)秒即可完成一片\r\n? 有EEPROM功能\r\n? 看門狗\r\n? 內(nèi)部集成MAX810專用復(fù)位電路(HD版本和90C版本才有),外部晶體20M以下時，可省外部復(fù)位電路。\r\n? 共3個16位定時器/計數(shù)器，其中定時器0還可以當(dāng)成2個8位定時器使用。\r\n? 外部中斷4路,下降沿中斷或低電平觸發(fā)中斷，PowerDown模式可由外部中斷低電平觸發(fā)中斷方式喚醒。\r\n? 通用異步串行口(UART)，還可用定時器軟件實現(xiàn)多個UART\r\n? 工作溫度范圍：-40 ~ +85℃(工業(yè)級) / 0 ~ 75℃(商業(yè)級)\r\n? 封裝：LQFP-44,PDIP-40,PLCC-44,PQFP-44.;
