82C900
stand-alone CAN-controller con-
taining independently running Full-CAN nodes according V2.0 part (active) specification maximum baudrate Mbaud each. independent message objects available assigned both nodes. This product either used together with host true stand-alone mode. Communication with host possible parallel (Infineon Motorola compatible) serial (SPI) interface. stand-alone mode 82C900 needs compatible E2PROM initialization. Further initialization then continue with CAN-messages. This ensures that 82C900 suitable wide variety applications. When 82C900 communicating serial interface, remaining pins from parallel interface used additional I/Os. reduce CPU-load improve real-time behavior, 82C900 hardware Gateway FIFO message objects) functionality. Additionally, 82C900 outstanding power-down features wich controlled CAN.
