Product Summary

The FT232RL is a USB to serial UART interface device which simplifies USB to serial designs and reduces external component count by fully integrating an external EEPROM, USB termination resistors and an integrated clock circuit which requires no external crystal, into the FT232RL. It has been designed to operate efficiently with a USB host controller by using as little as possible of the total USB bandwidth available.

Parametrics

FT232RL absolute maximum ratings: (1)Storage Temperature: -65℃ to 150℃; (2)Floor Life (Out of Bag) At Factory Ambient (30℃ / 60% Relative Humidity): 168 Hours; (3)Ambient Temperature (Power Applied): -40℃ to 85℃; (4)MTTF FT232RL: 11162037 hours; (5)MTTF FT232RQ: 4464815 hours; (6)VCC Supply Voltage: -0.5 to +6.00V; (7)DC Input Voltage - USBDP and USBDM: -0.5 to +3.8V; (8)DC Input Voltage - High Impedance Bidirectionals: -0.5 to + (VCC +0.5)V; (9)DC Input Voltage - All Other Inputs: -0.5 to + (VCC+0.5)V; (10)DC Output Current - Outputs: 24mA; (11)DC Output Current - Low Impedance Bidirectionals: 24mA; (12)Power Dissipation (VCC = 5.25V): 500mW.

Features

FT232RL features: (1)Single chip USB to asynchronous serial data transfer interface; (2)Entire USB protocol handled on the chip; (3)No USB specific firmware programming required; (4)Fully integrated 1024 bit EEPROM storing device descriptors and CBUS I/O configuration; (5)Fully integrated USB termination resistors; (6)Fully integrated clock generation with no external crystal required plus optional clock output selection enabling a glue-less interface to external MCU or FPGA; (7)Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232 ) at TTL levels; (8)128 byte receive buffer and 256 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput; (9)FTDIs royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases; (10)Unique USB FTDIChip-ID feature; (11)Configurable CBUS I/O pins; (12)Transmit and receive LED drive signals.
