ISP1132  
Universal Serial Bus compound hub with one-time  
programmable 80C51 microcontroller  
Rev. 02 — 27 June 2001  
Objective data  
1. General description  
The ISP1132 is a general purpose member of the ISP113x family of Universal Serial  
Bus (USB) hubs. It contains an 80C51 microcontroller with one-time programmable  
(OTP) code memory and a parallel I/O interface. The ISP1132 complies with the  
Universal Serial Bus Specification Rev. 1.1. The hub has 2 downstream ports and 3  
non-removable embedded functions. The hub controller is fully implemented in  
hardware, ensuring a fast response to host requests.  
The integrated 5 V to 3.3 V regulator allows direct connection to the USB power  
supply VBUS. The downstream ports are bus-powered and can interface low-power  
USB devices such as a joystick or a mouse. The ISP1132 uses SoftConnect™  
technology to connect to the USB host upon detection of VBUS. The low power  
consumption in ‘suspend’ mode allows easy design of equipment that is compliant  
with the ACPI™, OnNow™ and USB power management requirements.  
The integrated 80C51 microcontroller has 24 kbytes of OTP ROM and 768 bytes of  
data RAM. The code memory is protected against reading by an external device. A  
built-in watchdog timer resets the device in case of a microcontroller hang-up. To  
reduce power consumption, the microcontroller can be put in sleep mode or  
power-down mode.

A serial I2C-bus interface is provided for optional access to an external EEPROM.  
This allows the user to program the vendor ID, product ID or other user-defined  
parameters.  
The ISP1132 has built-in overcurrent sense inputs, supporting individual overcurrent  
protection for downstream ports. All ports (including the hub) have GoodLink™  
indicator outputs for easy visual monitoring of USB traffic. The ISP1132 has a  
reduced frequency (6 MHz) crystal oscillator to minimize Electro Magnetic  
Interference (EMI). These features allow significant cost savings in system design  
and easy implementation of advanced USB functionality into PC peripherals.  
2. Features  
■ Compound USB hub device with integrated hub repeater, hub controller, Serial  
Interface Engine (SIE), data transceivers and 5 V to 3.3 V voltage regulator  
■ Complies with Universal Serial Bus Specification Rev. 1.1  
■ Complies with ACPI, OnNow and USB power management requirements  
■ 2 downstream ports with automatic speed detection
