USBN9603 Datasheet | National Semiconductor

Description The USBN9603 is an integrated, USB Node controller that features enhanced DMA support with many automatic data handling features . It is patible with USB specification versions 1.0 and 1.1, and is an advanced version of the currently available USBN9602. A single IC integrates the required USB transceiver with a 3.3V regulator, a Serial Interface Engine (SIE), USB endpoint (EP) FIFOs, a versatile 8-bit parallel interface, a clock generator and a MICROWIRE/PLUS™ interface. Seven endpoint pipes are supported: one for the mandatory control endpoint and six to support interrupt, bulk and isochronous endpoints. Each endpoint pipe has a dedicated FIFO, 8 bytes for the control endpoint and 64 bytes for the other endpoints. The 8-bit parallel interface supports multiplexed and non-multiplexed style CPU address/data buses. A programmable interrupt output scheme allows device configuration for different interrupt signaling requirements.
