PCI Express mini card Dual CAN Bus Interface
The MCAN-1020 is engineered around the ARM7 highly integrated microcontroller.
This ARM7TDMI-S processor has very low power consumption and features 512 kB of on-chip high-speed flash memory.
It incorporates several communications ports, specifically a USB full-speed Device/Host/OTG Controller with 4 kB of endpoint RAM, and two Controller Area Network (CAN) channels.
The device controller enables 12 Mbit/s data exchange with a USB host controller. It consists of a register interface, serial interface engine, endpoint buffer memory, and a DMA controller. The serial interface engine decodes the USB data stream and writes data to the appropriate endpoint buffer. The status of a completed USB transfer or error condition is indicated via status registers.
An interrupt is also generated if enabled. When enabled, the DMA controller transfers data between the endpoint buffer and the USB RAM.
The Controller Area Network (CAN) is a serial communications protocol which efficiently supports distributed real-time control with a very high level of security.
Its domain of application ranges from high-speed networks to low cost multiplex wiring.
