See also ACCONEER’S LOW-POWER XM132/XE132 ENTRY RADAR MODULE WITH A SOLDERABLE DESIGN FEATURES PC is capable of serial transmission at up to 115,200 bps (step size of 8.68 microseconds!). Without which it could not be adopted to transfer data between a computer and a printer.Ī single integrated circuit called as UART known as universal asynchronous receiver/transmitter is used in conjunction with RS232. That are essential features when data transfer takes place between a computer and a printer. Full Duplex mode: SenderReceiver (T&R), two way simultaneously (as, telephone).Half Duplex mode: SenderReceiver(T/R), once at a time (as, radio-system).RS-232 Receiver(T) one-way (as, sensor data) Bus-based Communication (I^2C,SPI,PCI,PCI-EXPRESS, USB, SATA).? 28-Pin SSOP package Step 2: Serial Communication Using RS-232Ĭommunication between/among systems physically or remotely. ? USB-IF Logo Compliant with TID 10240590 ? Designed for Windows XP/2000 Certified Logo Drivers ? Supports Windows 98/SE, ME, 2000, XP, Windows CE3.0, CE. ? On-chip crystal oscillator running at 12MHz ? Supports default ROM or external EEPROM for device configuration ? 256-bytes buffer each for upstream and downstream data flow ? Supports Remote wake-up and power management PL2303 – FATURES Fully compliant with USB Specification v1.1 and USB CDC v1.1 Users just simply hook the cable into PC or hub’s USB port, and then they can connect to any RS-232 devices. By integrating all the function in a SSOP-28 package, this chip is suitable for cable embedding. Only minimum power is consumed from the host during Suspend. This device is also compliant with USB power management and remote wakeup scheme. With these, a much higher baud rate can be achieved compared to the legacy UART controller. Automatic handshake is supported at the Serial port. The USB bulk-type data is adopted for maximum data transfer. The two large on-chip buffers accommodate data flow from two different buses. The PL-2303 operates as a bridge between one USB port and one standard RS232 Serial port.
