Description:
PL-2303HX (Chip Rev D) or PL-2303HXD provides a convenient solution for connecting an RS232-like full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. PL-2303HXD highly compatible drivers could simulate the traditional COM port on most operating systems allowing the existing applications based on COM port to easily migrate and be made USB ready.
Application:
USB to serial dongle
POS device
printer
etc
Feature:
-Single-chip USB to Serial (RS232/RS422/RS485) asynchronous serial data transfer interface
-Fully Compliant with USB Specification v2.0 (Full-Speed)
-USB-IF Logo Compliant with TID 40000100
-UHCI/OHCI (USB1.1), EHCI (USB 2.0), xHCI (USB 3.0) Host Controller Compatible
-Integrated USB 1.1 Transceiver and 5V to 3.3V Regulator
-Integrated 96MHz clock generator (No external crystal required)
-Integrated OTPROM (One-Time Programming ROM) – no external EEPROM required.
o For writing and storing customer USB VID/PID, Serial Number, Product String, and other device startup configurations. (uses default settings if OTPROM is empty)
- Supports USB to RS232 Serial UART Interface
o Full-duplex transmitter and receiver (TXD and RXD)
o Six MODEM control pins (RTS, CTS, DTR, DSR, DCD, and RI)
o 5, 6, 7 or 8 data bits
o Odd, Even, Mark, Space, or None parity mode
o One, one and a half, or two stop bits
o Parity error, frame error, and serial break detection
o Programmable baud rate from 75 bps to 12M bps
o External RS232 driver power down control
o Independent power source for serial interface
- Supports RS-422/RS-485 like serial interface (TXD, DTR_N, and RTS_N pins should be externally pulled-up to 5V)
- Extensive Flow Control Mechanism
o Adjustable high/low watermark level

o 128-byte outbound buffer and 384-byte inbound buffer
- Supports Remote Wake-up from RS232 input pin signals (RI, RXD, DSR, DCD, CTS)
- Four (4) General Purpose I/O (GP0, GP1, GP2, & GP3) pins and Four (4) Auxiliary General Purpose I/O (RI_N, DSR_N, DCD_N, & CTS_N) pins.
- Supports Windows Selective Suspend by OTPROM configuration (Enable Remote Wakeup)
o Suspends power of chip when idle (COM port is closed)
-Provides royalty-free USB to Virtual COM Port drivers for Windows, Mac, Linux, Android
- -40 C to 85 C Operating Temperature
-Small footprint 28-pin SSOP or 32-pin QFN IC packages (RoHS compliant and Pb-free Green Compound
