USBN9603

- May 1998 USBN9603 Universal Serial Bus Full Speed Function Controller with Enhanced DMA Support PRELIMINARY March 2000 USBN9603 Universal Serial Bus Full Speed Function Controller with Enhanced DMA Support General Description The USBN9603 is an integrated, USB Node controller that features enhanced DMA support with many automatic data handling features. It is compatible 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.
