FT230XS-R

FTDI · USB Converters · SSOP-16-150mil

FT230XS-R from FTDI, in a SSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TXD output Transmit Asynchronous Data Output. TTL-level UART TX; 3.3V CMOS drive, tolerant of 5V input. Configurable output drive strength 4 mA (min) to 16 mA (max).
2 RTS# output Request To Send control output / handshake signal. Active low. Used for UART hardware flow control.
3 VCCIO power_in 1.8V - 3.3V supply for the I/O cells. Sets the logic level for UART and CBUS pins independently of the core VCC.
4 RXD input Receiving Asynchronous Data Input. TTL-level UART RX input, tolerant to 5V. Operates down to 1V with external pull-ups.
5 GND power_in 0V ground input. Tie to system ground along with pin 13.
6 CTS# input Clear To Send control input / handshake signal. Active low. Used for UART hardware flow control.
7 CBUS2 bidirectional Configurable CBUS I/O pin. Default configuration is TXLED#. Function is configured in the device MTP memory (see CBUS Signal Options, Table 3.7). Pulled to VCCIO via internal ~75kΩ resistor when in input mode.
8 USBDP bidirectional USB Data Signal Plus. USB 2.0 full-speed differential D+ line. Integrated 1.5k pull-up.
9 USBDM bidirectional USB Data Signal Minus. USB 2.0 full-speed differential D- line.
10 3V3OUT power_out 3.3V output at 50mA from the internal LDO regulator. May be used to power VCCIO. When VCC is 3.3V, pin 10 becomes an input pin and should be connected to pin 12 (VCC).
11 RESET# input Reset input, active low. Tie high (to 3V3OUT) for normal operation; pull low to reset the device.
12 VCC power_in 5V (or 3.3V) supply to the IC core. Powers the internal LDO regulators and USB transceiver. If VCC is 3.3V then 3V3OUT (pin 10) must also be driven with 3.3V input.
13 GND power_in 0V ground input. Tie to system ground along with pin 5.
14 CBUS1 bidirectional Configurable CBUS I/O pin. Default configuration is RXLED#. Function is configured in the device MTP memory (see CBUS Signal Options, Table 3.7). Pulled to VCCIO via internal ~75kΩ resistor when in input mode.
15 CBUS0 bidirectional Configurable CBUS I/O pin. Default configuration is TXDEN. Function is configured in the device MTP memory (see CBUS Signal Options, Table 3.7). Pulled to VCCIO via internal ~75kΩ resistor when in input mode.
16 CBUS3 bidirectional Configurable CBUS I/O pin. Default configuration is SLEEP#. Function is configured in the device MTP memory (see CBUS Signal Options, Table 3.7). Pulled to VCCIO via internal ~75kΩ resistor when in input mode.
