ISP116X - Embedded Host Controller Series
ISP1160 / 01 embedded host controller
ISP1160 / 01 is a Universal Serial Bus (USB) host controller, which is an ISP1160 new generation chip, which is fully compliant with USB2.0, which supports full speed (12Mbit / s) and low speed (1.5Mbit / s) transmission specifications. In addition, it also provides two lower-pass ports that are ideal for inbidden systems that require USB hosts and portable devices.
Inclusive systems integrated with ISP1160 / 01 such as PDA, intelligent calls, digital cameras, etc., can play a USB host, which is not necessary to interpose via a computer. In other words, systems with ISP1160 / 01 can be directly connected to a device with USB upload ports such as a USB printer, a USB camera, a USB keyboard, or a USB mouse.
ISP1161A1 single-chip host and device controller
The ISP1161 is the first generation of ISP1161A1, which is also the industry's first product that integrates the USB host end and the USB device end function within a single chip. Point-to-point connection. It can act as a stand-alone host or device through software control, and even simultaneously with the functionality of the host and device. It has a 16-bit parallel output (PIO) and DMA interface, which can be connected to most RISC instruction set processors, digital signal processors (DSP) and microconresers. It is fully compliant with USB 2.0 specifications, fairly suitable for embedded or conference systems, such as applying personal digital assistants (PDAs), set-top boxes (STBs), digital cameras (DSC), mobile phones, and other embedded systems that require USB hosts and device functions system.
The general interface bus of ISP1161A1 makes it easy and flexibly integrated into all embedded systems, which also makes this USB master function as a value-added function of all portable devices.
Since ISP1161A1 can act as a host and device controller simultaneously, a personal computer and an embedded system, or even a point-to-point connection between two embedded systems.
In the chip, the buffer double buffer memory can provide a rate of rate conversion between the ISP1161A1 and the system processor, so that the system processor can read the USB data packet in the original speed, and ISP1161A1 low-suspend power consumption and low clock output, etc. Features conform to ACPI, ONNOW and USB power management requirements, making it easily applied to the device.
ISP1161 successfully successfully launched the world's first prototype products that Philips successfully launched the world's first real-in-USB2.0 USBON-THE-Go (OTG) supplementary specification, USBON-The-Go (OTG) is defined in 2001. New specifications, specifically for portable devices that use the same connection port as host and peripheral function. This prototype demonstrates the feasibility of USBOTG additional specifications, and the portable device can automatically be automatically based on the external connector defined in this specification. Switch between host mode and peripheral mode. Philips performs very active in members of the USB-IFON-THE-GO Working Group to help develop this new and highly groundbreaking standards. At present, Philips and industry leader cooperate with mobile equipment manufacturers with ON-THE-GO. Functional products, this prototype will be displayed in future exhibitions, please refer to our OTG page for USBOTG product details.
