PL2303 (PL2303HX) USB To TTL Converter Adapter Module

The PL-2303 operates as a bridge between one USB port and one standard RS232 Serial port. The two large on-chip buffers accommodate data flow from two different buses. The USB bulk-type data is adopted for maximum data transfer. Automatic handshake is supported at the Serial port. With these, a much higher baud rate can be achieved compared to the legacy UART controller.

This device is also compliant with USB power management and remote wakeup scheme. Only minimum power is consumed from the host during Suspend. By integrating all the function in a SSOP-28 package, this chip is suitable for cable embedding. Users just simply hook the cable into PC or hub’s USB port, and then they can connect to any RS-232 devices.

Features:

• Integrated USB transceiver; no external resistors required
• Supports Baud rates from 75bps to 1.2Mbps
• 256 bytes receive buffer and 256 bytes transmit buffer
• Supports RS232 Serial interface
• Supports automatic handshake mode
• On-chip 3.3V voltage regulator
• Supports default ROM or external EEPROM for device configuration

Applications:

1. Upgrade of RS-232 legacy devices to USB
2. Cellular phone USB interface cable
3. USB interface cable
4. USB to RS-232 serial adapter

Country of origin : China

Note: Pins are presoldered to the module.
