CJMCU-2232 FT2232HL USB to UART/FIFO/SPI/I2C/JTAG/RS232 Module External Memory

CJMCU-2232 FT2232HL USB to UART/FIFO/SPI/I2C/JTAG/RS232 Module External Memory Beskrivelse

The CJMCU-2232HL FT2232H is FTDI's fifth-generation USB device chip. The FT2232H is a USB 2.0 High-Speed (480 Mbit/s) to UART/FIFO interface. It is capable of operating in a variety of industry-standard serial or parallel interface configurations. Building the innovative features of the FT2232, the FT2232H features two Multi-Protocol Synchronous Serial Engines (MPSSEs), allowing simultaneous communication using JTAG, I2C, and SPI channels.
A 512-byte receive buffer and a 512-byte transmit buffer utilize buffering techniques for high data throughput.
Battery charger detection allows mobile devices to detect the presence of a charger the USB port, enabling higher current/faster battery charging.
Low operating current of 8 mA (typical) and USB suspend current of 125 µA (typical). Low USB bandwidth consumption.
FTDI's royalty-free Virtual COM Port (VCP) and Direct (D2XX) drivers eliminate the need for USB driver development in most cases.

Module USB supply voltage: DC5V; USB 2.0 full-speed compatible.
Built-in 3.3V/1.8V LD0 regulator.
Extended operating temperature range: -40 to 85
20-pin SSOP and QFN packages (RoHS compliant).
Compatible with UHCI/OHCI/EHCI host controllers.
Integrated power--reset circuit.
Data transfer rate: 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.
True 3.3V CMOS driver outputs and TTL inputs (operates down to 1.8V with external pull- resistors).
I/O voltage levels from 1.8V to 3.3V (tolerant to 5V). Configurable I/O pin drive current.
The entire USB protocol is handled this chip, requiring no USB-specific firmware programming.
The FT1248 serial-to-parallel interface operates in 1-,
