Feature:

1. USB supply voltage: DC5V, USB 2.0 full speed compatible.

2. Built-in 3.3V / 1.8V LD0 regulator.

3. Extended operating temperature range: -40 ° C ~ 85 ° C

4. 20-pin SSOP and QFN packages (RoHS compliant).

5. Compatible with UHGI / 0HGI / EHCI host controller

6. Integrated power-on-reset circuit.

7. The data transfer rate is 1 megabyte per second.

8. Each chip has a pre-programmed unique USB serial number.

9. Supports bus-powered, self-powered and high-power bus-powered USB configurations.

10. Built-in + 3.3V level shifter for USB I/O.

11. Built-in + 3.3V level shifter for USB I/O.

12. True 3.3V CMOS driver output and TTL input. (Working voltage drops to 1V8 through external pull-up resistor)

13. I/O voltage levels range from 1.8V to 3.3V (withstand voltage to 5V). The drive current of the I/O pin can be configured.

14. The entire USB protocol is processed on this chip and does not require USB-specific firmware programming.

15. FT1248 serial parallel interface, using 1, 2, 4, or 8-bit horizontal, similar to the SPI slave 1-bit mode.

16. Integrated 2048-byte multiple-programmable (MTP) memory for storage device description and CBUS I/O configuration.

17. Integrated clock generator eliminates the need for an external crystal and has a clock output option for seamless connection to an external MCU or FPGA.

18. 512-byte receive buffer and 512-byte transmit buffer, using buffer technology to achieve é«?data throughput.

19. Battery charger detection. The mobile device can use it to detect the presence of a charger on the USB port for higher current/faster charging of the battery.

20. Low operating current of 8 mA (typ) and USB suspend current of 125 μA (typ). Low USB bandwidth consumption.

21. FTDI's Virtual COM Port (VCP) and Direct (D2XX) drivers are in most cases exempt from USB driver development requirements.

Typical application:

 

Single-chip USB to dual-channel UART (RS232, RS422 or RS485).

MCU USB to dual channel FIFO.

MCU USB to dual channel JTAG.

MCU USB to dual channel SPI

MCU USB to dual channel I2C

MCU USB to dual channel

Dual combination of single-chip USB to the above interface

Single-chip USB to dual channel interface.

Idle serial optical interface.

The target interface (such as memory) of the MCU USB to the CPU is independent of the two machines.
