NXP Semiconductors
I
Generic processor interface, non-multiplexed and variable latency, with a configurable
32-bit or 16-bit external data bus; the processor interface can be defined as
variable-latency or SRAM type (memory mapping)
I
Slave DMA support to reduce the load of the host system CPU during the data transfer
to or from the memory
I
Integrated Phase-Locked Loop (PLL) with a 12 MHz crystal or an external clock input
I
Integrated multi-configuration FIFO
I
Optimized ‘msec-based’ or ‘multi-msec-based’ Philips Transfer Descriptor (PTD)
interrupt
I
Tolerant I/O for low voltage CPU interface (1.65 V to 3.6 V)
I
3.3 V-to-5.0 V external power supply input
I
Integrated 5.0 V-to-1.8 V or 3.3 V-to-1.8 V voltage regulator (internal 1.8 V for
low-power core)
I
Internal power-on reset and low-voltage reset
I
Supports suspend and remote wake-up
I
Target current consumption:
N
Normal operation; one port in high-speed active: I
N
Suspend mode: I
I
Built-in configurable overcurrent circuitry (digital or analog overcurrent protection)
I
Available in LQFP128 and TFBGA128 packages
3. Applications
The ISP1760 can be used to implement a Hi-Speed USB compliant host controller
connected to most of the CPUs present in the market today, having a generic processor
interface with de-multiplexed address and data bus. This is because of the efficient
slave-type interface of the ISP1760.
The internal architecture of the ISP1760 is such that it can be used in a large spectrum of
applications requiring a high-performance internal host controller.
3.1 Examples of a multitude of possible applications
I
Set-top box: for connecting external high-performance mass storage devices
I
Mobile phone: for connecting various USB devices
I
Personal Digital Assistant (PDA): for connecting a large variety of USB devices
I
Printer: for connecting external memory card readers, allowing direct printing
I
Digital Still Camera (DSC): for printing to an external USB printer, for direct printing
I
Mass storage: for connecting external memory card readers or other mass storage
devices, for direct back-up
The low power consumption and deep power management modes of the ISP1760
make it particularly suitable for use in portable devices.
