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
– 8-MHz Low Voltage mode (3.0-4.0V @ 8MHz)
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
– 8-MHz Low Voltage mode (3.0-4.0V @ 8MHz)
– 16-MHz Low Voltage mode (3.0-4.0V @ 16MHz)
