1 INTRODUCTION

The ST7HUB is a USB microcontroller based on

ST7 core, which is an enhanced industry-standard

architecture. The USB module of the ST7HUB is a

compound device, consisting of a 3-port HUB and

an attached embedded function. To the USB host,

the embedded function appears as an attached

port of the HUB with its own device address and

endpoints.

In addition to the peripherals for USB full speed

data transfer and to the HUB, the ST7HUB in-

cludes all the necessary features for a gaming pe-

ripheral or a multimedia keyboard application.

– 10-bit Analog-to-Digital converter (ADC) with 16

multiplexed analog inputs and external referenc-

es. 4 of the channels have optimized layout so

that external source can have up to 50k

ance

– 8-bit Auto-Reload Timer with 2 input capture

functions, 2 PWM outputs and external clock in-

put

– Serial Peripheral Interface

– Low voltage reset ensuring proper power-on or

power-off of the device (selectable by option)

– Digital Watchdog

The ST72FHUB devices are the Flash versions of

the ST7HUB in a TQFP64 10x10 package.

The ST7HUB devices are the ROM versions in a

TQFP64 10x10 package.

The device is also available in TQFP44 and SO34

packages without HUB function.
