Preliminary
Standalone TwinCAN Controller
82C900
Architectural Overview
The Standalone TwinCAN device provides several submodules to control the data flow
and to configure the peripheral function:
Features:
• Two interface channels are implemented for the communication with a host device:
• Both communication channels are based on byte transfers. In order to minimize the
• Powerful initialization mechanism for all registers, the device can be configured via
• Additional input/output functionality controlled by CAN messages. The transmission of
• The clock control unit can be supplied with an external clock. Alternatively, an on-chip
• Power Saving features have been implemented. A Sleep Mode and a Power-Down
• The internal power saving status can be monitored at output pins. This allows flexible
• The Device Controller unit generates the internal target address by concatenating the
• The Interrupt Control unit passes the interrupt requests generated by the TwinCAN
• The Port Control unit can be used to select the required functionality of the port pins
Data Sheet
– the Multiplexed Data/Address Bus can be used by an external CPU to read and
– alternatively, a Synchronous Serial Channel (SSC) may be selected to read out the
communication overhead, all internal 16 bit and 32 bit wide registers can be accessed
in Page Mode requiring only one address byte.

also used by an external control device (microcontroller, CPU, etc.) in order to
exchange control and status information.
