Each device has a chip select (CS), input-output clock (I/O CLK), data input (DATA IN) and serial data output (DATA OUT) that provide a direct 4-wire synchronous serial peripheral interface (SPI™, QSPI™) port of a host microprocessor.
When interfacing with a TMS320 DSP, an additional frame sync signal (FS) indicates the start of a serial data frame.
The devices allow high-speed data transfers from the host.
The INV CLK input provides further timing flexibility for the serial interface.
