The FT2232D-REEL is a USB-to-serial/FIFO IC developed for flexible use FTDI Chip, a market leader in USB connectivity products, makes it. The FT2232D-primary REEL’s characteristics consist of its dual-channel USB-to-serial/FIFO interfaces, integrated clock circuitry, and programmable data bus interface.
If you’re a programmer looking for a flexible and reliable USB-to-serial converter that’s simple to integrate into your project, look no further than the FT2232D-REEL. Data capture, hardware debugging, and firmware development are just some of the uses it has. The FT2232D-REEL is a robust and adaptable tool that can help developers get their projects up and running quickly and easily thanks to its fast data transfer rates and versatile interface options.
The second-generation FT232BM and FT245BM chips from FTDI are combined into the FT2232D, a USB to serial UART interface device. Without the need for an extra USB hub, a single downstream USB port can be turned into two IO channels, each of which can be set up as either an FT232BM-style UART interface or an FT245BM-style FIFO interface. As a bonus, a new high drive level option lets multiple devices share the bus by making the UART/FIFO IO pins on each device drive out at about three times the normal power level.
Each of the FT2232D’s two IO channels (A and B) can be set up separately as a UART interface (like the FT232BM) or a FIFO interface (like the FT245BM). There are also a number of different IO modes that can be used with these channels.
The POR feature is already built into the device. There is a RESET# pin that can be connected to Vcc to reset the device from outside logic, but most of the time it can be safely connected to Vcc. A RSTOUT# pin has been added to the new POR circuit so that it can reliably reset MCUs and other devices on the outside.
This is done to confirm that the oscillator and clock multiplier PLL frequencies are steady prior to USB enumeration.
Each of the FT2232D’s channels has a VCCIO pin that can get power from a source with a voltage between 3V and 5V. This makes it possible to individually set the output voltage drive level for each channel. This indicates that you can connect a device to, say, 3.3 V logic without using an external level converter. I.C.
The PWREN# pin will become active again the next time the device is enumerated by USB after being turned off during USB suspend. This can be used to directly drive a transistor or P-channel MOSFET when the power of external circuitry needs to be switched. The function to pull down the BM is still available (it is set in the external EEPROM). When the power is off (PWREN# is high), the FIFO/UART IO lines will be slightly pulled down. This mode sends any remaining voltage on external circuitry controlled by PWREN# to GND before power is turned off. This is done to make sure that the external circuitry will reset correctly when power is restored.
There is a Send Immediate or Wake Up (SI/WU) signal pin on each chip channel. They share a single pin that serves two purposes. Strobe low on this pin while the USB bus is in suspend mode to resume from sleep (WakeUp) (and remote wakeup is enabled in the EEPROM). Most of the time, this can be used to wake up the Host PC. If this pin is strobed low during normal operation, any data in the device’s RX buffer will be sent over USB on the next Bulk-IN request from the drivers, no matter how big the packet is. In some situations, this can be used to get the most out of the fast speeds of USB.
The FT2232D’s USB suspension mode suspend current is often less than 100 A. (without the 1.5K pull-up resistor on USBDP). This offers peripherals more room to reach the USB Suspend current limit of 500uA.
The TX buffer timeout can be changed via USB from 1ms to 255ms in 1ms steps. This makes the device better for protocols that need quick responses from small data packets.
The FT2232D device has the same kind of improved Vcc decoupling that BM devices have.
The FT2232D can read and write to EEPROMs with model numbers 93C46 (64 bytes), 93C56 (128 bytes), and 93C66 (256 x 16 bits). The thing doesn’t use the extra space. While the FT2232D is in reset, an external MCU or logic can use it. When a 93C56 or 93C66 is used, there are an extra 64 words (128 bytes) in the user area.
In summary, the FT2232D-REEL is a flexible USB-to-serial/FIFO IC with many possible uses. Its primary characteristics include of a dual-channel USB-to-serial/FIFO interface, an integrated clock circuitry, and a highly adaptable data bus interface. If you’re a programmer looking for a flexible and reliable USB-to-serial converter that’s simple to integrate into your project, go no further than the FT2232D-REEL.Its powerful data transfer speeds and adaptable interface optilooks make it useful in a variety of contexts.It can be used in a wide range of situations because it can send and receive data quickly and has a flexible interface.
In conclusion, the FT2232D-REEL is a great choice for developers who need a reliable and flexible USB-to-serial converter for their project. Because of its powerful capabilities and flexible interface options, it performs well for a variety of applications. Any project that requires USB connectivity, such as data collection, hardware debugging, firmware programming, and other duties, can be completed with the help of the FT2232D-REEL.
