Document No.: FT 000060 FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC Datasheet Version 2.08 Clearance No.: FTDI 78 Future Technology Devices International Ltd FT4232H Quad High Speed USB to Multipurpose UART/MPSSE IC Highly integrated design includes +1.8V LDO th The FT4232H is FTDIs 5 generation of regulator for VCORE, integrated POR function USB devices. The FT4232H is a USB 2.0 and on chip clock multiplier PLL (12MHz 480MHz). High Speed (480Mb/s) to UART/MPSSE FTDI FT232B style, asynchronous serial UART ICs. The device features 4 UARTs. Two of interface option with full hardware handshaking these have an option to independently and modem interface signals. configure an MPSSE engine. This allows Fully assisted hardware or X-On / X-Off software handshaking. the FT4232H to operate as two UART/Bit- UART Interface supports 7/8 bit data, 1/2 stop Bang ports plus two MPSSE engines used 2 bits, and Odd/Even/Mark/Space/No Parity. to emulate JTAG, SPI, I C, Bit-bang or Auto-transmit enable control for RS485 serial other synchronous serial modes. The applications using TXDEN pin. FT4232H has the following advanced Operational configuration mode and USB Description strings configurable in external features: EEPROM over the USB interface. Single chip USB to quad serial ports with a Low operating and USB suspend current. variety of configurations. Configurable I/O drive strength (4,8,12 or Entire USB protocol handled on the chip. No 16mA) and slew rate. USB specific firmware programming required. Supports bus powered, self powered and high- USB 2.0 High Speed (480Mbits/Second) and power bus powered USB configurations. Full Speed (12Mbits/Second) compatible. UHCI/OHCI/EHCI host controller compatible. Two Multi-Protocol Synchronous Serial Engine USB Bulk data transfer mode (512 byte packets (MPSSE) on channel A and channel B, to in High Speed mode). simplify synchronous serial protocol (USB to Dedicated Windows DLLs available for USB to 2 2 JTAG, I C, SPI or bit-bang) design. JTAG, USB to SPI, and USB to I C applications. Independent Baud rate generators. +1.8V (chip core) and +3.3V I/O interfacing RS232/RS422/RS485 UART Transfer Data Rate (+5V Tolerant). up to 12Mbaud. (RS232 Data Rate limited by Extended -40C to 85C industrial operating external level shifter). temperature range. FTDIs royalty-free Virtual Com Port (VCP) and Compact 64-LD Lead Free LQFP or QFN Direct (D2XX) drivers eliminate the package requirement for USB driver development in +3.3V single supply operating voltage range. most cases. ESD protection for FT4232H IOs: Optional traffic TX/RX indicators can be added Human Body Model (HBM) 2kV, with LEDs and an external 74HC595 shift Machine Mode (MM) 200V, register. Charge Device Model (CDM) 500V, Adjustable receive buffer timeout. Latch-up free. Support for USB suspend and resume conditions via PWREN , SUSPEND and RI pins.
