The OTG Controller provides all the control, monitoring and switching functions required
in OTG operations.
The advanced NXP Slave Host Controller is designed for highly optimized USB host
functionality. Many advanced features are integrated to fully utilize the USB bandwidth. A
number of tasks are performed at the hardware level. This reduces the requirement on the
microprocessor and thus speeds up the system.
The NXP Peripheral Controller is a high performance USB device with up to 14
programmable endpoints. These endpoints can be configured as double-buffered
endpoints to further enhance the throughput.
A 12 MHz-to-48 MHz clock multiplier PLL is integrated on-chip. This allows the use of a
low-cost 12 MHz crystal that also minimizes ElectroMagnetic Interference (EMI) because
of low frequency. No external components are required for the operation of PLL.
The integrated transceivers (for typical downstream port) directly interface to the USB
connectors (type A) and cables through some termination resistors. The transceiver is
compliant with
The ISP1362 has a built-in overcurrent protection circuitry. This feature monitors the
current drawn on the downstream V
the current threshold. The built-in overcurrent protection feature can be used when the
port acts as a host port.
The bus interface connects the microprocessor to the USB host and the USB device,
allowing fast and easy access to both.
4096 bytes (host) and 2462 bytes (device) of built-in memory provide sufficient space for
the buffering of USB traffic. Memory in the Host Controller is addressable by using the fast
and versatile direct addressing method.
