Universal Serial Bus compound hub with integrated keyboard

controller

Rev. 01 — 23 March 2000

Objective speciﬁcation

1. General description

The ISP1130 integrates a Universal Serial Bus (USB) hub with a keyboard controller

into a single chip, which complies with Universal Serial Bus Speciﬁcation Rev. 1.1 and

the USB Device Class Deﬁnition for Human Interface Devices (HID). The hub has

1 to 2 downstream ports and 1 to 3 non-removable embedded functions, one of

which is dedicated to the keyboard operation. 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 V_BUS. The downstream ports are either bus-powered or hybrid-powered and

can interface low-power USB devices such as a joystick or a mouse. ISP1130 uses

SoftConnect™ technology to connect to the USB host upon detection of V_BUS. 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 keyboard controller is based on the 80C51 family and has 8 kbytes of

mask ROM and 256 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 activate the built-in

keyboard matrix.

The ISP1130 has built-in overcurrent sense inputs, supporting individual and global

overcurrent protection for downstream ports. All ports (including the hub) have

GoodLink™ indicator outputs for easy visual monitoring of USB trafﬁc. The ISP1130

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.
