FT2232C & FT2232L - Dual USB UART/FIFO ICs
产品详细信息
the ft2232c is the 3rd generation of ftdi"s popular usb uart/fifo ic family and the ft2232l is a lead free version of it.
this device features two multi-purpose uart/fifo controllers which can be configured individually in several different modes. as well as a uart interface, a fifo interface and the bit-bang io mode of the 2nd generation ft232bm and ft245bm devices, the ft2232c offers a variety of additional new modes of operation including a multi-protocol synchronous serial engine (mpsse) interface which is designed specifically for synchronous serial protocols such as i2c, jtag and spi bus.
key hardware features:
＊single chip usb <=> dual channel serial/parallel ports with a variety of configurations
＊entire usb protocol handled on the chip: no usb-specific firmware programming required
＊ft232bm-style uart interface option with full handshaking & modem interface signals
＊uart interface supports 7/8 data bits, 1/2 stop bits and odd/even/mark/space/no parity
＊data transfer rate of 300 baud => 1m baud (rs232)
＊data transfer rate of 300 baud => 3m baud (ttl and rs422/rs485)
＊auto transmit enable control for rs485 serial applications using txden pin
＊ft245bm-style fifo interface option with bi-directional data bus and simple 4-wire handshaking interface
＊data transfer rate up to 1m byte/second
＊enhanced bit-bang mode interface option
＊new synchronous bit-bang mode interface option
＊new multi-protocol synchronous serial engine (mpsse) interface option
＊new mcu host bus emulation mode option
＊new fast opto-isolated serial interface mode option
＊interface mode and usb desc-ription strings configurable in external eeprom
＊eeprom configurable on-board via usb
＊support for usb suspend and resume conditions via pwren# and si/wu pins
＊support for bus powered, self powered and high-power bus powered usb configurations
＊integrated power-on-reset circuit with optional reset input and reset output pins
＊5v and 3.3v logic io interfacing with independent level conversion on each channel
＊integrated 3.3v ldo regulator for usb io
＊integrated 6mhz - 48mhz clock multiplier pll
＊usb bulk or isochronous data transfer modes
＊4.35v to 5.25v single supply operating voltage range
＊uhci/ohci/ehci host controller compatible
＊usb 2.0 full speed (12m bits/second) compatible
＊compact 48-ld lqfp package
＊available as a lead-free device (ft2232l) compliant to eu directive 2002/95/eg rohs
application areas:
＊usb <=> dual port rs232 converters
＊usb <=> dual port rs422/rs485 converters
＊upgrading legacy peripheral designs to usb
＊usb instrumentation
＊usb i2c bus interfaces
＊usb jtag programming
＊usb spi bus interfaces
＊usb industrial control
＊field upgradeable usb products
＊galvanically isolated products with usb interface
