USB controllers with 8-bit parallel bus and SPI interfaces

December 11, 2012 // By Julien Happich
Alpha Micro Components is now stocking the FTDI FT12 series of high performance USB controller ICs designed to facilitate mass data transfer from embedded systems applications to peripheral devices fitted with old style serial connectors.

Featuring native drivers present in the operating system, they are also ideal for isochronous support for video applications in security, industrial control and quality inspections. Operating at 12 Mbits/s and designed to the USB 2.0 specification, the FTDI FT12 series support direct memory access (DMA) operation, while providing system interfaces for 8-bit parallel bus and SPI (Serial Peripheral Interface) Slave. The FT12 series is configurable as a standard device class and as such there is no need to add USB drivers.

They have been designed specifically so that engineers can quickly understand the device functionality and architecture, as well as take advantage of application software and standard class drivers currently available and installed within the market. The FT120 and FT122 are both supplied in TSSOP-28 and QFN-28 packages, while the FT121 is offered in TSSOP-16 and QFN-16 package options. All of these advanced USB controller ICs have an operating temperature range of -40 to 85°C.
