PHILIPS單片機選型指南
★ 80C51體系結(jié)構(gòu)：如果您用過8051內(nèi)核的單片機就很容易入門；★ 超高速CPU內(nèi)核：18MHz的LPC900相當(dāng)于108MHz的傳統(tǒng)80C51；2 ★ 豐富的片內(nèi)外圍資源：WDT,UART,I C,SPI, D/A,2 E PROM, RTC,A/D,比較器,CCU,掉電檢測等；★ 內(nèi)置高精度RC振蕩器：標(biāo)稱頻率7.3728MHz，精度可達1%；★ 超小型TSSOP封裝（另有DIP、PLCC封裝），能最大限度節(jié)省電路板面積；★ 超低功耗：支持低速晶振，3級省電模式，典型掉電電流僅1μA；★ 在線ICP編程，僅需引出5根線(VCC, GND, RST,P0.4, P0.5)；★ Flash存儲器：容量1～16KB，具有ISP、IAP功能，2 可以當(dāng)作E PROM使用；★ 工業(yè)級產(chǎn)品，抗干擾能力強，操作電壓2.4～3.6V，管腳數(shù)8～44，I/O可兼容5V邏輯。
