FT230XS-R

FT230XS-R Description

The FT230X is a small USB to basic serial UART interface device that simplifies USB implementations in a small optimized package with minimal UART signals and reduces external component count by fully integrating an MTP memory and an integrated clock circuit that does not require an external crystal. It is intended to work efficiently with USB host controllers by consuming as little bandwidth as feasible in comparison to the overall USB bandwidth available.

FT230XS-R Features

The FT230X is a USB to serial UART interface with optimised pin count for smaller PCB designs and the following advanced features:

• Configurable CBUS I/O pins.
• Transmit and receive LED drive signals.
• UART signal inversion option.
• + 5V Single Supply Operation.
• Internal 3V3/1V8 LDO regulators
• USB 2.0 Full Speed compatible.
• Single chip USB to asynchronous serial data transfer interface.
• UHCI/OHCI/EHCI host controller compatible.
• Integrated power-on-reset circuit.
• Extended operating temperature range; -40 to 85⁰C.
• Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, and RS232) at TTL levels.
• Fully integrated AVCC supply filtering - no external filtering required.
• Synchronous and asynchronous bit bang interface options with RD# and WR# strobes.
• Configurable I/O pin output drive strength; 4 mA (min) and 16 mA (max).
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
• Low operating and USB suspend current; 8mA (active-typ) and 70uA (suspend-typ).
• 512 byte receive buffer and 512 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
• FTDI’s royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
• Available in compact Pb-free 16 pin SSOP and 16 pin QFN packages (both RoHS compliant).
• Entire USB protocol handled on the chip. No USB specific firmware programming required.
• Fully integrated 2048 byte multi-time programmable (MTP) memory, storing device descriptors and CBUS I/O configuration.
• Fully integrated clock generation with no external crystal required plus optional clock output selection enabling a glue-less interface to external MCU or FPGA.
