USB4640/USB4640i

- Memory Stick Pro-HG Duo Format 1.01

- Memory Stick, MS Duo, MS-HS, MS Pro-HG, MS Pro

- Memory Stick Duo 1.10

- xD-Picture Card 1.2

• 8051 8-bit microprocessor

- 60 MHz - single-cycle execution

- 64 KB ROM | 9 KB RAM

• Integrated regulator for 1.8 V core operation

1.2

Software Features

• Hub and flash media reader/writer configuration from a single source: External I²C ROM or external SPI ROM,

where the following features are then available:

- Customizable vendor ID, product ID, and device ID

- 12-hex digits maximum for the serial number string

- 28-character manufacturer ID and product strings for the flash media reader/writer

1.3

OEM Selectable Hub Features

The USB4640/USB4640i provides a default configuration that may be sufficient for most applications following a reset.

The USB4640/USB4640i can instead be configured by an external I²C EEPROM or SPI ROM.

• Compound device support on a port-by-port basis

- a port is permanently hardwired to a downstream USB peripheral device

• Select over-current sensing and port power control on an individual or ganged (all ports together) basis to match

the OEM’s choice of circuit board component selection

• Port power control and over-current detection/delay features

• Configure the delay time for filtering the over-current sense inputs

• Configure the delay time for turning on downstream port power

• Bus-powered or self-powered selection

• Hub port disable or non-removable configurations

• Flexible port mapping and disable sequencing supports multiple platform designs

• Programmable USB differential-pair pin location eases PCB layout by aligning USB signal lines directly to connec-

tors

• Programmable USB signal drive strength recovers USB signal integrity using 4 levels of signal drive strength

• Indicate the maximum current that the 2-port hub consumes

• Indicate the maximum current required for the hub controller
