PL2303SA Bridge Controller

PL2303SA Introduction

A flexible USB-to-serial bridge controller called the PL2303SA offers a straightforward method of adding serial communication ports to a computer or other USB-enabled device. It is the perfect answer for various industrial and consumer applications since it is made to simplify communication between devices that use USB interfaces and RS232 serial protocols.

PL2303SA Description

The PL2303SA is an easy, small-factor solution for attaching a full-duplex, asynchronous serial device (TX-RX only) to any host that supports the USB standard. Prolific offers highly compatible drivers that can imitate the conventional COM port on most operating systems, making it simple to convert and make USB-capable to any existing COM port-based programs (using TX-RX only). Compared to conventional UART (Universal Asynchronous Receiver Transmitter) ports, the PL2303SA can achieve higher throughput via USB bulk transfer mode and huge data buffers.

By customizing the driver, the PL2303SA’s flexible baud rate generator could be programmed to produce any rate between 75 bps and 115 kbps. The PL2303SA has a very compact footprint and was specifically created with mobile and embedded solutions in mind. It can easily fit into any connectors and handheld devices. The PL2303SA is ideal for bus-powered operation with plenty of power left over for the associated devices because of its extremely low power consumption in both operating and suspend modes. The RS232-like serial port side of the PL2303SA has a flexible signal level requirement that enables direct connection to any 3.3V1.8V range devices.
