The PCIe-Mini-CAN board is engineered around the NXP LPC2387 microcontroller. This highly integrated 32-bit microcontroller, based on the ARM7TDMI-S processor, has very low power consumption and features 512 kB of on-chip high-speed flash memory. It incorporates several communication 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.
Block Diagram: 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 that 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.
Applications:
This board is optimally suited for communications gateway and protocol converters. This is a perfect solution for:
- Avionics equipment
