Inicore Inc. offers various CAN controller architectures, all designed for system-on-chip integrations. They are predefined and verified, ready for an easy integration and giving you the flexibility to optimize your standard-based functionality, setting your design apart from the competition.
Designed using the basic CAN architecture from Bosch, each module comes with features specific to your applications need. The modules are full CAN2.0B compliant bus controllers, efficiently handling all communication transactions on the CAN bus. Application specific functions are add-ons and are built around as a wrapper; they don't influence the main core and therefore its function is always guaranteed.

Since we launched the iniCAN core in 1994, it has been deployed in applications such as aerospace, automation, automotive, industrial control, printers-systems, network and telecom. The trends goes towards applications to use CAN as a general bus medium for module level communication. It has been used in various FPGA and ASIC technologies, and therefore proven its conformity to the CAN2.0B standard.

NEW: CANmodule-IIx - CAN controller with Message Filter

This core provides a low gate-count CAN system interface. Receive and transmit buffer use on-chip memories. Several features such as number of message filters, register readback, and fixed configuration are selectable to minimize the gate-count.

• CAN 2.0B compliant
• Seperate clock domains for CAN clock and System clock
• Up to 3 programmable acceptance filters. Message filter covers: ID, IDE, RTR, 2 first data bytes for optimal Device Net support
• 16 messages deep receive FIFO
• 1 high priority transmit buffer
• 16 messsages deep transmit FIFO
• AMBA 2.0 Advanced Peripheral Bus Interface
• 8/16/32-bit wide data path
• Status & configuration interface
• Programmable interrupt controller
