The SAK-CIC310-OSMX2HT IC is supposed to be connected to devices of the Infineon
AUDO-NG 32bit microcontroller device family. The connection has to be done in a way
that today’s AUDO-NG 32-bit microcontroller MLI, ASC, or SSC interfaces remain
untouched. On the other hand the FlexRay Communication controller requires
communication bandwidth of 10 MBit/s and more to download the full message
bandwidth of the two FlexRay links. Beside this requirement additionally the SAK-
CIC310-OSMX2HT needs to be operative with a minimum pin account and area.
Therefore two small serial interfaces (MLI, SSC) and an additional parallel interface are
implemented.
For the SAK-CIC310-OSMX2HT concept three options are implemented in parallel to
minimize the risk and to increase the options for a system composed out of the SAK-
CIC310-OSMX2HT and an AUDO-NG 32-bit microcontroller device and still to handle
the application requirements. These three interfaces are the SSC Interface (usable as
SPI and synchronous ASC Interface), a parallel Interface, and the Micro Link Interface
(MLI). All AUDO-NG 32-bit microcontroller family member are equipped with serial
interfaces (ASC and SSC).
Three options are presented for the system solution based on these three
communication interfaces.
2.1
The first and preferred option is to connect the SAK-CIC310-OSMX2HT via the MLI
interface to the AUDO-NG 32bit microcontroller family. The MLI has the advantage
realizing a fast and smart communication interface with a low pin count and SPI like SW
protocol handling. The transmission rate is high enough to handle the data traffic that is
generated from the SAK-CIC310-OSMX2HT FlexRay Protocol engine to the AUDO-NG
32-bit microcontroller device and vice versa.
