TTL-232R-3V3 cable is a series of USB to TTL serial UART converter cables that combine the FT232RL USB to serial UART interface chip device, which can handle all USB signals and protocols. This cable provides a quick and easy way to connect TTL-level serial port devices to USB. Each TTL-232R cable contains a small internal electronic circuit board, using the FT232R molded into one end of the cable's USB connector. The cable supports FTDIChip-ID, with a unique USB serial number, written into the FT232R. This feature can be used to create a security code or password to protect file transfers when using the cable. Connect directly to a microcontroller UART or I/O pins.UHCI / OHCI / EHCI host controller compatible.6 way outputs provide Tx,Rx, RTS#, CTS#, VCC and GND Data transfer rates from 300 baud to 3 Mbaud at TTL levels.Fully assisted hardware(RTS#/CTS#) or X-On / X-Off software handshakingInternal EEPROM with user writeable area.USB 2.0 Full Speed compatible.Support for FT232R FTDIChip-ID feature for improved security.TTL-232R Converter Cable provides a USB to TTL Serial interface with various end connectors.On board FT232RL provides single chip USB to asynchronous serial data transfer interface.Entire USB protocol handled by the electronics in the cable USB.Low USB bandwidth consumption.-40°C to +85°C operating temperature range.
