FT2232H -高速双 USB UART/FIFO
IC |
|
FT2232H是FTDI的第5代USB设备芯片。 FT2232H是一个USB2.0高速（480 MB/秒）至UART/FIFO 芯片。 具有在多种工业标准串行或并行接口配置的能力。
在FT2232的创新功能的基础上，FT2232H有两个多协议同步串行引擎（MPSSEs）允许使用JTAG，I2C和SPI两个通道同时进行通信。
FT2232H是无铅（符合RoHS）64引脚LQFP/ QFN和56引脚QFN封装。

Key Hardware Features |
|
- Single chip USB to dual serial /
parallel ports with a variety of configurations.
- Entire USB protocol handled on the
chip. No USB specific firmware programming required.
- USB 2.0 High Speed (480Mbits/second)
and Full Speed (12Mbits/second) compatible.
- Dual Multi-Protocol
Synchronous Serial Engine (MPSSE) to simplify synchronous serial
protocol (USB to JTAG, I2C, SPI or bit-bang) design.
- Dual independent UART or
FIFO ports configurable using MPSSEs.
- Independent
Baud rate generators.
-
RS232/RS422/RS485 UART Transfer Data Rate up to 12Mbaud. (RS232 Data Rate limited by external level shifter).
- USB to parallel
FIFO transfer data rate up to 10Mbyte/sec.
- Single channel synchronous FIFO mode
for transfers up to 40 Mbytes/sec.

interface mode simplifies CPU interface design.
- MCU host bus
emulation mode configuration option.
- Fast
Opto-Isolated serial interface option.
- FTDI’s
royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
- Adjustable receive buffer
timeout.
-
Option for transmit and receive LED drive signals on each channel.
- Enhanced bit-bang Mode interface
option with RD# and WR# strobes.
- FT245B-style FIFO interface option

+1.8V LDO regulator for VCORE, integrated POR function and on chip
clock multiplier PLL (12MHz – 480MHz).
- Asynchronous serial UART interface
option with full hardware handshaking and modem interface signals.
- Fully assisted hardware or X-On /
X-Off software handshaking.
- UART Interface supports 7/8 bit
data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.
- Auto-transmit enable control for
RS485 serial applications using TXDEN pin.
- Operational configuration mode and
USB Description strings configurable in external EEPROM over the USB
interface.
- Configurable I/O drive strength
(4,8,12 or 16mA) and slew rate.
- Low operating and USB suspend
current.
