Note that this series is now under EOL and is not recommended for new designs.
The FT51A series provides an 8051-compatible core with best in class performance and unique features including multiple ADCs, USB2.0 Full Speed Device, and USB hub function targeted at cascading multiple FT51 systems, or to connect an additional USB peripheral like a mouse or keyboard.
The FT51A acts as a USB hub supporting two downstream ports: the internal 8051 core and other peripherals (SPI, UART etc.), and an external downstream port (e.g. mouse, keyboard, mass storage device, etc.). The hub can optionally be disabled (under register control), resulting in the 8051 core appearing at the upstream port.

Bridgetek provides a developmenttoolchain based on SDCC ANSI-C compiler suite for the FT51A series. It is fully integrated with the open source Eclipse IDE with C/C++ Development Tooling (CDT). The FT51A Eclipse integrated toolset includes FT51A sample applications to enable the ability to start a new project design quickly.
FT51A Interface driver support
The FT51Atoolchainis 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 HUB or device solutions. All drivers will be provided as source code for easy adaptation and modification.
Firmware Download and Debug
With the plug-in developed by Bridgetek, 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.
