FT93x series – 32 bit MCU

The FT93x series includes the FT930, FT931, FT932 and FT933 which are complete System-On-Chip 32-bit RISC microcontrollers for USB to multi-interface bridging and embedded applications featuring a high level of integration and low power consumption. With a D2XX hardware engine built-in, it is compatible with D2XX drivers.

Using the industry standard GCC compiler, together with the Eclipse IDE, the FT9xx Toolchain (V.2.3.1)  will allow the FT93x to utilise a wide variety of third-party and open source software.

    Design Development Support

    FT93x Series Firmware Development

    FT9xx tool chain v2.3.1 is based on GNU C/C++ and assembly compiler for the FT9xx series. It is fully integrated with the open source Eclipse IDE with C/C++ Development Tooling (CDT). The FT9xx Eclipse integrated toolset includes FT9xx sample applications to enable the ability to start a new project design quickly. An open source real time OS FreeRTOS is ported to the FT9xx and comes together with the tool chain.

    FT93x Interface driver support

    The upcoming FT9xx tool chain v2.3.1 is supported with a suite of free libraries to control each function block in addition to a collection of USB libraries to enable a range of USB host or device solutions. All drivers will be provided as source code for easy adaptation and modification.

    Firmware Download and Debug

    With the plug-in we have developed, the functionality of Eclipse is extended to support loading of compiled firmware into the target device via a dedicated 1-wire debug pin on the ICs. Running and debugging the firmware is also supported via the debugger pin with up to 3 breakpoints supported to assist debug. A dedicated debugger/programmer module is available to support these devices and interface with the Eclipse IDE. There is also an additional USB DFU feature available which allows the IC to be updated via USB direct meaning that the debugger/programmer module is not required.
