XC2000 - microcontrollers for the cars application market
The XC2000 family is based on a 16/32-bit CPU with 80MHz clockworks. The internal Flash memory goes up to 1.2 MB, the part is manufactured in 0.13 ėm technology and will be delivered in packages of 64 to 176 pins.
The peripheral with the different variations consists of, e.g.:
| > | USICs (Universally Serial interface channels) are flexible and can be used as an UART as well as LIN interface, buffered SPIŪ (Serial Peripheral interface), NCbus (Inter IC) and IIS interface (Inter IC Sound). |
| > | A MultiCAN module (CAN Rev. 2.0B active) offers up to 64 freely mapping message objects for up to three CAN knots as well as gateway functionality. |
| > | Synchronizable A/D converters with altogether up to 24 channels and optional data preconverting. These converters offer special safety properties: they can track down, for example, defective connections and synchronized incoming redundant signal scans. |
| > | The MPU (Memory Protection
Unit) offers additional
advantages for developers
of security systems, because
they help to integrate the
software of third providers
(e.g., AUTOSAR). In this
case the MPU partitions the
various software components
and seals them off from
the outside. In addition, the
memory contents are protected.
This allows that both
safety critical and safety uncritical
software tasks are
separately processed in secured,
respectively nonsecured
arrays. Also the
MPU controls the process
of the bulk partitioning of
the different software tasks
and offers reliable mechanisms
for the avoidance of
interferences. |
