Introduction
1.1
Members of the 16-bit Microcontroller Family
The microcontrollers in the Infineon 16-bit family have been designed to meet the high
performance requirements of real-time embedded control applications. The architecture
of this family has been optimized for high instruction throughput and minimized response
time to external stimuli (interrupts). Intelligent peripheral subsystems have been
integrated to reduce the need for CPU intervention to a minimum extent. This also
minimizes the need for communication via the external bus interface. The high flexibility
of this architecture allows to serve the diverse and varying needs of different application
areas such as automotive, industrial control, or data communications.
The core of the 16-bit family has been developed with a modular family concept in mind.
All family members execute an efficient control-optimized instruction set (additional
instructions for members of the second generation). This allows easy and quick
implementation of new family members with different internal memory sizes and
technologies, different sets of on-chip peripherals, and/or different numbers of IO pins.
The XBUS concept (internal representation of the external bus interface) provides a
straightforward path for building application-specific derivatives by integrating
application-specific peripheral modules with the standard on-chip peripherals.
As programs for embedded control applications become larger, high level languages are
favored by programmers, because high level language programs are easier to write, to
nd
debug and to maintain. The C166 Family supports this starting with its 2
generation.
The 80C166-type microcontrollers were the first generation of the 16-bit controller
family. These devices established the C166 architecture.
The C165-type and C167-type devices are members of the second generation of this
family. This second generation is even more powerful due to additional instructions for
HLL support, an increased address space, increased internal RAM, and highly efficient
management of various resources on the external bus.
Enhanced derivatives of this second generation provide more features such as
additional internal high-speed RAM, an integrated CAN-Module, an on-chip PLL, etc.
The design of more efficient systems may require the integration of application-specific
peripherals to boost system performance while minimizing the part count. These efforts
are supported by the XBUS, defined for the Infineon 16-bit microcontrollers (second
generation). The XBUS is an internal representation of the external bus interface which
opens and simplifies the integration of peripherals by standardizing the required
interface. One representative taking advantage of this technology is the integrated CAN
module.
The C165-type devices are reduced functionality versions of the C167 because they do
not have the A/D converter, the CAPCOM units, and the PWM module. This results in a
smaller package, reduced power consumption, and design savings.
