USBN9604-28M/NOPB

The USBN9604-28M/NOPB from Texas Instruments is an integrated Universal Serial Bus (USB) full-speed node controller featuring enhanced Direct Memory Access (DMA) support. This device is designed to be compatible with USB specification versions 1.0 and 1.1, offering advanced data handling capabilities.

Key features include a 3.3V regulator, a Serial Interface Engine (SIE), USB endpoint FIFOs, an 8-bit parallel interface, and a clock generator. It supports seven endpoint pipes, including a mandatory control endpoint and six for interrupt, bulk, and isochronous endpoints. Each endpoint pipe has a dedicated FIFO, with 8 bytes for the control endpoint and 64 bytes for others. The 8-bit parallel interface accommodates multiplexed and non-multiplexed CPU address/data buses.

This controller operates within a voltage range of 3V to 5.5V and has an operating temperature range of 0°C to 70°C. It consumes approximately 30mA of current. The device is available in a 28-SOIC package, measuring 0.295 inches (7.50mm) in width, making it suitable for various design applications.

Outstanding features include low EMI, low standby current, and a 24 MHz oscillator. It also offers a fully static HALT mode with asynchronous wake-up for bus-powered operation and a programmable interrupt output scheme for flexible signaling requirements. Power-up reset and startup delay counters simplify system design.
