FT232RL Datasheet PDF – USB UART IC – FTDI Chip

Part Number : FT232RL

Function : USB to asynchronous serial data transfer interface, USB UART IC

Package : 28 Pin SSOP, QFN-32 Type

Manufacturers : Future Technology




The FT232RL is a USB to serial UART interface .


1. Single  chip  USB  to  asynchronous  serial  data transfer interface.
2. Entire  USB  protocol  handled  on  the  chip.  No USB specific firmware programming required.
3. Fully  integrated  1024  bit  EEPROM  storing device descriptors and CBUS I/O configuration.
4. Fully integrated USB termination resistors.
5. Fully  integrated  clock  generation  with  no external  crystal  required  plus  optional  clock output selection  enabling  a  glue-less  interface to external MCU or FPGA.
6. Data  transfer  rates  from 300  baud to 3  Mbaud(RS422, RS485, RS232 ) at TTL levels.
7. 128  byte  receive  buffer  and  256  byte  transmit buffer  utilising  buffer  smoothing  technology  to allow for high data throughput.

STN1170 Datasheet – Multiprotocol OBD to UART Interpreter – OBD

Part Number : STN1170

Function : OBD to UART interpreter IC

Package : 44 Pin TQFP ( STN1170-I/PT ) and 44 QFN ( STN1170-I/ML ) Type

Manufactures : OBD Solutions ( http://www.obdsol.com )


STN1170 Multiprotocol Interpreter

The STN1170 is an OBD to UART interpreter IC designed to provide bi-directional half-duplex communication with the vehicle’s On-Board Diagnostic system (OBD-II). It supports all legislated OBD-II protocols, as well as two proprietary networks: GM Single Wire CAN (GMLAN), and Ford Medium Speed CAN (MS CAN).
