FT312D-32L1C-R Integrated Circuits (ICs)

FT312D-32L1C-R, manufactured by FTDI Chip, is a type of interface controller. It is designed to bridge a mobile electronic device with a host controller. It supports the 2-wire serial peripheral Interface Bus (SPI) Interface and provides USB2.0 High Speed Full Speed USB Slave Interface or Enhanced Full Speed (bulk-only) USB interface. The FT312D-32L1C-R also includes a voltage regulator, which has an input voltage range of 3.3V to 5.5V. In addition, it is also equipped with an oscillator which consumes only 13mA of power.

The FT312D-32L1C-R application field can be found in various areas, including consumer electronics, automotive, and mobile phone applications. In consumer electronics, it is used in digital camera, digital TV, and data logger applications. In automotive, it can be found in automotive body and audio systems. In the area of mobile phones, it is used for audio and video capture, data transfer and handshake acknowledgement. This device also finds application in medical and industrial automation systems.

Concerning the FT312D’s working principle, it is designed to convert SPI signals from one protocol to another. The FT312D-32L1C-R interface controller is capable of communicating with both host and peripheral device. It acts as an SPI Slave, communicating with the SPI Master, and as a USB device, communicating with the USB host (computer).

When communicating with the SPI Master, the FT312D translates the bus protocol into USB data which is then forwarded to the USB host. When communicating with the USB host, the FT312D receives the USB data and converts it into an SPI bus protocol, then sending it to the SPI Master. The FT312D supports transfers up to 48MHz, allowing high speed data transfers.

In addition to acting as an embedded data converter, the FT312D interface controller also offers the ability to recycle USB signals. This feature is useful when multiple devices are connected to a single USB connection. When enabled, the FT312D sends back the signal to original device.

The FT312D-32L1C-R also provides a number of integrated power management functions, including voltage regulators, voltage supervisors, and oscillators. These integrated components keep the controller at an optimal temperature during device operations.

Overall, the FT312D-32L1C-R interface controller offers a power-efficient, cost-effective solution for bridging mobile electronic devices to a host controller. It provides fast data transfer, embedded data conversion, and convenient power management functions. This makes it an ideal choice for consumer electronics, automotive, and mobile phone applications.
