ABOUT PL2303GT

The new PL2303GT chip is one of the latest G-Series IC product added to the popular PL2303 USB to Serial

(UART) Bridge Controller family, replacing the PL2303RA USB to RS232 serial chip. It provides an advanced

full-featured single-chip bridge solution for connecting a full-duplex UART asynchronous serial interface

device to any Universal Serial Bus (USB) capable host. The PL2303GT provides highly compatible USB

drivers to simulate the traditional COM port (via virtual COM Port) on most operating systems allowing

existing serial UART applications based on legacy COM port to easily migrate and be made USB ready.

PL2303GT integrates a high baud rate RS-232 transceiver that meets the EIA/TIA-232F and CCITT V.28

communications interface specifications. The RS-232 transceiver is a 3-transmitters and 5-receivers device

with a high-efficient charge pump circuit embedded. This high-efficient charge pump circuit with 1uF external

capacitors provides the bipolar output to the transmitters, and makes the transmitters to deliver the RS-232

output voltage levels. Under normal operation, PL2303GT operates at very low power consumption with

guaranteed data rate up to 1000kbps. PL2303GT also has an active-low shutdown indicating pin that can

serve as a shutdown indicator for special application purposes.

The new PL2303GT is pin-to-pin compatible with the PL2303RA chip. It also integrates an RS-232

transceiver, an internal precise clock generator (no external crystal required), USB 1.1 transceiver, Serial

Interface Engine (SIE), LDO voltage regulator, power-on- reset (POR), FIFO data buffers, and OTPROM.

The PL2303GT added several new features and enhancements:

• Integrated termination resistors and pull-up resistor to reduce PCB external components.

• New USB drivers for different OS platforms with faster performance and advanced features.

• Precise baud rate generator (up to 1Mbps).

• OTPROM can be programmed directly through USB (no high voltage generator required).

• Larger TX/RX FIFO data buffers (1024-byte).

• Supports 3.3V VBUS voltage operation.

• Unique USB Serial Number for each IC.

• 4 GPIO pins (all input mode at power-up) with easy to use SDK. Can also be configured as TX/RX access LEDs, and I2C EEPROM (EE_SCL, EE_SDA) interface in OTPROM.

The PL2303GT is designed to support a wide-range of serial RS232 application including mobile,

embedded, industrial, consumer, healthcare, navigation, and wearable solutions in mind. It provides a

small footprint that could easily fit in to any connectors and handheld devices. With very small power

consumption in either operating or suspend mode, the PL2303GT is perfect for bus powered operation

with plenty of power left for the attached devices.
