1 / 60 page  © National Semiconductor Corporation, 2003 - May 1998 www.national.com June 2003 Revision 1.3 USBN9603/USBN9604 Universal Serial Bus Full Speed Node Controller with Enhanced DMA Support General Description The USBN9603/4 are integrated, USB Node controllers. Other than the reset mechanism for the clock generation cir- cuit, these two devices are identical. All references to “the device” in this document refer to both devices, unless other- wise noted. The device provides enhanced DMA support with many au- tomatic data handling features. It is compatible with USB specification versions 1.0 and 1.1, and is an advanced ver- sion of the USBN9602. The device integrates the required USB transceiver with a 3.3V regulator, a Serial Interface Engine (SIE), USB end- point (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 con- trol endpoint and six to support interrupt, bulk and isochro- nous 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 pro- grammable interrupt output scheme allows device configu- ration for different interrupt signaling requirements. Outstanding Features q Low EMI, low standby current, 24 MHz oscillator q Advanced DMA mechanism q Fully static HALT mode with asynchronous wake-up for bus powered operation q 5V or 3.3V operation q Improved input range 3.3V signal voltage regulator q All unidirectional FIFOs are 64 bytes q Power-up reset and startup delay counter simplify sys- tem design q Simple programming model controlled by external controller q Available in two packages — USBN9603/4SLB: small footprint for new designs and portable applications — USBN9603/4-28M: standard package, pin-to-pin compatible with USBN9602-28M Block Diagram Physical Layer Interface (PHY) Media Access Controller (MAC) Transceiver 24 MHz Oscillator Clock Generator XIN XOUT CLKOUT Microcontroller Interface D+ D- Upstream Port INTR V3.3 A0/ALE D7-0/AD7-0 Endpoint/Control FIFOs VReg AGND RESET VCC GND MODE1-0 Serial Interface Engine (SIE) USB Event Detect Clock Recovery CS RD WR National Semiconductor is a registered trademark of National Semiconductor Corporation.
