Our USB to serial bridge cables provide seamless communication between serial devices and Windows, Mac, Android and Linux platforms over their USB ports. Built round the Prolific PL2303HXD chipset, these cables support all the features of that chipset.
Prolific USB to Serial Adapters
The PL2303 is a family of USB to serial bridge controllers which can connect a variety of serial devices to a USB host, allowing full RS232/422/485 or TTL communications. By simulating COM ports, these chips make serial devices and applications USB-ready.
By taking advantage of USB bulk transfer mode, large data buffers, and automatic flow control, the PL2303 achieves higher throughput than traditional UART's. The flexible baud rate generator can be programmed to generate any rate between 75 bps to 12M bps.
With a small footprint and low power consumption in either operating or suspend mode, the PL-2303 is perfect for bus powered operation with power left for attached devices. Flexible signal level requirement on the RS232-like serial port side also allows the PL2303 to connect directly to any 3.3V~1.8V range devices.
Prolific Storage Device Controllers
Prolific Storage Device Controllers offer both USB 2.0 and SuperSpeed USB 3.0 controllers. The line is made up of low-power, single-chip USB-to-SATA compliant bridge controllers that are designed to perform seamless protocol transfer between USB Host and SATA interface storage devices like Hard Disk Drives, Optical Disk Drives, and Solid-State Drives. All are implemented according to the USB Bulk-Only Mass Storage Class Specification. Additionally, all are backward compatible and interoperable with lower USB protocol devices, hosts and hubs.
A high performance 8-bit microcontroller, which can be used to support versatile system applications such as one button backup, power control, and other USB port features, is integrated into each controller.
Prolific USB Host to Host & General Purpose Controllers
Host to Host
The Prolific host to host bridge controllers are single chip solutions designed for file transfer, networking and resource sharing over USB host ports. They can be used with Windows Easy Transfer cables and Microsoft Windows Easy Transfer program or Prolific’s ULinq software. Computers can be connected in a peer-to-peer network in various configurations, without the overhead and complicated configurations of Ethernet networks.
The PL2551 is a single chip Hi-Speed USB 2.0 General-Purpose Microcontroller (MCU). It provides customers a cost-effective and time-to-market USB device controller solution. With a diversity of IO ports and peripherals, it can easily interface with various external devices and applications such as motion sensors, modems, CMOS sensors, medical/healthcare, industrial, fingerprint, security, and others. Flexible endpoint configuration, including its buffer partition, allows users to easily establish control of isochronous in/out (ISO), bulk-in/out or interrupt in/out (INT) pipes to communicate with the USB host
