FT2232 듀얼채널 USB-Serial 모듈 -UART, SPI, I2C, JTAG
(FT2232 Dual Channel USB-Serial Breakout -UART, FIFO, SPI, I2C, JTAG)
개요
- 본 제품은 FT2232 듀얼채널 USB-Serial 모듈 -UART, SPI, I2C, JTAG입니다.
- USB를 멀티포트 JTAG, SPI, I2C 인터페이스로 변환하여 주는 제품입니다.
- FTDI사의 FT2232H 5세대 칩을 장착하였으며, USB 2.0 Hi-Speed (480Mb/s)를 지원합니다.
- 다양한 산업 표준 시리얼이나 병렬 인터페이스로 설정이 가능합니다.
특징
- Module USB supply voltage: DC5V;
- USB 2.0 full speed compatible.
- Built-in 3.3V / 1.8V LDO regulator.
- Extended operating temperature range: -40°C to 85°C
- 20-pin SSOP and QFN packages (RoHS compliant).
- Compatible with UHCI / OHCI / EHCI host controllers.
- Integrated power-on-reset circuit.
- The data transfer rate is 1 megabyte per second.
- Each chip has a pre-programmed unique USB serial number.
- Supports bus-powered, self-powered and high-power bus-powered USB configurations.
- Built-in + 3.3V level shifter for USB I/O.
- Built-in + 3.3V level shifter for USB I/O.
- True 3.3V CMOS driver output and TTL input. (The operating voltage drops to 1V8 through an external pull-up resistor)
- The I/O voltage level is from 1.8V to 3.3V (withstand voltage to 5V). The drive current of the I/O pin can be configured.
- The entire USB protocol is processed on this chip and does not require USB-specific firmware programming.
- FT1248 serial parallel interface in 1, 2, 4, or 8-bit mode. Similar to the SPI slave 1-bit mode.
- Integrated 2048-byte multiple-programmable (MTP) memory for storage device descriptions and CBUS I/O configuration.
- An 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.
- A 512-byte receive buffer and a 512-byte transmit buffer enable high data throughput with buffering.
- Battery charger detection. Mobile devices can use it to detect the presence of a charger on the USB port for higher current/faster\
- Charge the battery quickly.
- 8 mA (typ) of low operating current and 125 μA (typ) of USB suspend current. Low USB bandwidth consumption.
- FTDI royalty-free virtual COM port (VCP) and direct (D2XX) drivers are exempt from USB drivers in most cases
- Development requirements.
