Prolific USB1.1 to Serial Bridge Controllers with Advanced Features now available in USA.
Pittsford, NY: Prolific’s USB ICs – widely used overseas - are now available from their USA distributor Saelig Company Inc. (NY). Prolific Technology Inc., a leading Taiwan IC design house whose USB ICs are in volume use in Far East-manufactured USB-connected consumer products, have released PL-2303HX a new, low-cost, high-performance USB-to-Serial Bridge Controller, previously only available to Far East manufacturers but now available in the USA. PL-2303HX provides a convenient and versatile solution for connecting serial devices to any USB host. Due to its ubiquitous use in mass-produced devices, PL-2303HX’s tried-and-tested, widely-compatible, royalty-free drivers offer rugged stability in simulating a traditional COM port on most operating systems (XP, Vista, Mac OS X 10.5 Leopard, Linux, etc.), thus allowing existing or new COM-port-based applications to easily migrate and be instantly USB-ready where no true COMports exist. Additionally, the flexible signal level requirements on the RS-232 serial port side allow PL-2303HX to connect directly to 3.3V to 1.8V devices – a feature not available on competing ICs. PL-2303HX integrates the on-chip clock generator and OTP ROM, eliminating external components, board area and cost.
By taking advantage of USB bulk transfer mode, large data buffers, and automatic flow control, PL-2303HX is capable of achieving faster throughput compared to traditional UART solutions. PL-2303HX’s flexible baud rate generator can be programmed to generate any rate between 75 bps to 12M bps, with versatile data formats such as 1/1.5/2 stop bits, none/odd/even/mark/space parity and 5/6/7/8 data bits.
PL-2303HX
has been specifically designed
with mobile
and
embedded
solutions in mind,
and is available in a tiny 5mm
square footprint that can easily fit
inside connectors or handheld
devices.
With very low power consumption
in either operating or
suspend
mode,
PL-2303HX
is perfect
for bus-powered
operation,
leaving plenty of power available
for attached
USB devices.
Unlike similar ICs, PL-2303HX
supports full handshaking for RS232 and
RS422/RS485 2-wire interfaces.
PL-2303HX’s
on-chip OTP ROM stores startup device configurations such as product and serial
number ID.
PL-2303HX, fully USB2.0(High-Speed)-compliant, offers extensive flow control features: adjustable high/low watermark level, automatic hardware or software flow control, inbound data buffer overflow detection, etc. and configurable 256-byte inbound/outbound buffers. Additionally, PL-2303HX supports remote wake-up from modem input signals (there are six modem control pins - RTS, CTS, DTR, DSR, DCD, and RI) and has 8 useful GPIO pins.
Drivers supplied for PL-2303HX are Windows and Vista-certified and the IC is USB-IF Logo Compliant with TID 40000100.
Supplied in a small footprint 28-pin SSOP or 32-pin QFN IC package, PL-2303HX is now available from their USA distributor Saelig Company. Other Prolific products are also available from Saelig.
