8 3.0 Intrductin The PL2303EA prvides a cnvenient slutin fr cnnecting an RS232-like full-duplex asynchrnus serial device t any Universal Serial Bus (USB) capable hst. By prviding a virtual COM prt thru USB, the PL2303EA cmpatible drivers culd simulate the traditinal serial COM prt n mst perating systems allwing the existing serial prt applicatins t easily migrate and be made USB ready. Additinally, the PL2303EA prvides USB prt system-level ESD (electrstatic discharge) prtectin that eliminates the need fr external ESD prtectin cmpnents t minimize PCB size and save BOM csts. The PL2303EA ffers ESD prtectin n the USB prt pins up t ± 15k Human Bdy Mdel (HBM) and is accrding t the IEC ESD specificatin. By taking advantage f USB bulk transfer mde, large data buffers, and autmatic flw cntrl, the PL2303EA is capable f achieving higher thrughput cmpared t traditinal UART (Universal Asynchrnus Receiver Transmitter) prts. When real RS232 signaling is nt required, baud rate higher than bps culd be used fr even higher perfrmance. The flexible baud rate generatr f the PL2303EA culd be prgrammed t generate any rate between 75 bps t 12M bps. The PL2303EA is exclusively designed fr mbile and embedded slutins in mind, prviding a small ftprint that culd easily fit in t any cnnectrs and handheld devices. With very small pwer cnsumptin in either perating r suspend mde, the PL2303EA is perfect fr bus pwered peratin with plenty f pwer left fr the attached devices. Flexible signal level requirement n the RS232-like serial prt side als allws the PL2303EA t cnnect directly t any 3.3~1.8 range devices. PL2303EA Prduct Datasheet Dcument ersin 1.1.0
