PHILIPS單片機(jī)選型指南
★ 80C51體系結(jié)構(gòu)：如果您用過8051內(nèi)核的單片機(jī)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(cè)等；★ 內(nèi)置高精度RC振蕩器：標(biāo)稱頻率7.3728MHz，精度可達(dá)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(jí)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(chǔ)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(jí)產(chǎn)品，抗干擾能力強(qiáng)，操作電壓2.4～3.6V，管腳數(shù)8～44，I/O可兼容5V邏輯。

SL811開發(fā)資料_包含源程序_電路圖_芯片資料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.
