Bridgetek/FTDI's FT51A series provides an 8051-compatible core with best-in-class performance and unique features including multiple ADCs, a USB2.0 full speed device, and a 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, such as SPI and UART, and an external downstream port for applications such as a mouse, keyboard, or mass storage device). The hub can optionally be disabled (under register control), resulting in the 8051 core appearing at the upstream port.
