FT230X
(USB to BASIC UART IC)
The FT230X is a USB to serial UART
interface with optimised pin count for
smaller PCB designs and the following
advanced features:
Single chip USB to asynchronous serial data
transfer interface.
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.
Data transfer rates from 300 baud to 3 Mbaud
(RS422, RS485, and RS232) at TTL levels.
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.
Configurable CBUS I/O pins.
Transmit and receive LED drive signals.
UART interface support for 7 or 8 data bits, 1 or 2
stop bits and odd / even / mark / space / no parity
Synchronous and asynchronous bit bang interface
options with RD# and WR# strobes.
USB Battery Charger Detection. Allows for USB
peripheral devices to detect the presence of a
higher power source to enable improved
charging.
Device supplied pre-programmed with unique
USB serial number.
USB Power Configurations; supports bus- powered,
self-powered and bus-powered with power switching
Integrated +3.3V level converter for USB I/O.
True 3.3V CMOS drive output and TTL input;
operates down to 1V8 with external pull ups.
Tolerant of 5V input
Configurable I/O pin output drive strength;
4 mA (min) and 16 mA (max).
Integrated power-on-reset circuit.
Fully integrated AVCC supply filtering - no
external filtering required.
UART signal inversion option.
+ 5V Single Supply Operation.
Internal 3V3/1V8 LDO regulators
Low operating and USB suspend current;
8mA (active-typ) and 125uA (suspend-typ).
UHCI/OHCI/EHCI host controller compatible.
USB 2.0 Full Speed compatible.
Extended operating temperature range; -40 to
85⁰C.
Available in compact Pb-free 16 pin SSOP and 16
pin QFN packages (both RoHS compliant).

3.3 CBUS Signal Options
FT230X USB TO BASIC UART IC
Version 1.4
Document No.: FT_000566 Clearance No.: FTDI# 260
The following options can be configured on the CBUS I/O pins. CBUS signal options are common to both
package versions of the FT230X. These options can be configured in the internal MTP memory using the
software utility FT_PROG or MPROG, which can be downloaded from the FTDI Utilities
(www.ftdichip.com). The default configuration is described in Section 8.

IO Pad is tri-stated
Output a constant 1
Output a constant 0
Enable transmit data for RS485
Output is low after the device has been configured by
USB, then high during USB suspend mode. This output
can be used to control power to external logic P-Channel
logic level MOSFET switch. Enable the interface pull-down
option when using the PWREN# in this way.
Transmit data LED drive – pulses low when transmitting
data via USB. See Section 7.5 for more details.
Receive data LED drive – pulses low when receiving data
via USB. See Section 7.5 for more details.
LED drive – pulses low when transmitting or receiving
data via USB. See Section 7.5 for more details.
Goes low during USB suspend mode. Typically used to
power down an external TTL to RS232 level converter IC
in USB to RS232 converter designs.
24 MHz Clock output.*
12 MHz Clock output.*
6 MHz Clock output.*
CBUS bit bang mode option. Allows up to 4 of the CBUS
pins to be used as general purpose I/O. Configured
individually for CBUS0, CBUS1, CBUS2 and CBUS3 in the
internal MTP memory. A separate application note,
AN232R-01, available from FTDI website
(www.ftdichip.com) describes in more detail how to use
CBUS bit bang mode.
Battery charge Detect, indicates when the device is
connected to a dedicated battery charger host. Active
high output.
Inverse of BCD Charger
Synchronous and asynchronous bit bang mode WR#
strobe output.
Synchronous and asynchronous bit bang mode RD#
strobe output.
