ST92163 - GENERAL DESCRIPTION

1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST9216x family brings the enhanced ST9 reg-

ister-based architecture to a new range of high-

performance

microcontrollers

specifically

de-

signed for USB (Universal Serial Bus) applica-

tions. Their performance derives from the use of a

flexible 256-register programming model for ultra-

fast context switching and real-time event re-

sponse. The intelligent on-chip peripherals offload

the ST9 core from I/O and data management

processing tasks allowing critical application tasks

to get the maximum use of core resources. The

ST9 MCU devices support low power consumption

and low voltage operation for power-efficient and

low-cost embedded systems. In the ST92163 fam-

ily, four different types of device are available:

Normal Voltage Devices with LVD function

They operate in Normal Voltage Mode only (4.0-

5.5V @ 24MHz) and include the Low Voltage De-

tector (LVD) function.

Normal Voltage Devices without LVD function

They operate in Normal Voltage Mode only (4.0-

5.5V @ 24MHz) and do not include the Low Volt-

age Detector (LVD) function.

8-MHz Low Voltage Devices

They do not include the Low Voltage Detector

(LVD) function and they support two operating

voltage modes:

– Normal Voltage mode (4.0-5.5V @ 24MHz) with

full functionality including USB.

– 8-MHz Low Voltage mode (3.0-4.0V @ 8MHz)

without the USB interface.

16-MHz Low Voltage Devices

They do not include the Low Voltage Detector

(LVD) function and they support three operating

voltage modes:

– Normal Voltage mode (4.0-5.5V @ 24MHz) with

full functionality including USB.

– 8-MHz Low Voltage mode (3.0-4.0V @ 8MHz)

without the USB interface.

– 16-MHz Low Voltage mode (3.0-4.0V @ 16MHz)

without the USB interface.

Figure 1, on page 7 shows the operating range of

the ST92163 devices.
