Details are subject to change without notice. 1/6 1 ST7HUB 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 includes all the necessary features for a gaming peripheral or a multimedia keyboard application. - 10-bit Analog-to-Digital converter (ADC) with 16 multiplexed analog inputs and external references. 4 of the channels have optimized layout so that external source can have up to 50k impedance - 8-bit Auto-Reload Timer with 2 input capture functions, 2 PWM outputs and external clock input - 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. 2/6 ST7HUB INTRODUCTION (Cont'd) Figure 1.
