PDF datasheet for the SJA1000, a stand-alone CAN bus controller, here as a 250 KB file with a _3 suffix that likely marks a document edition, though the name does not confirm it. It details the register map, pin functions, bus interface and timing, useful when diagnosing industrial, automotive or embedded boards that communicate over CAN. Verify the transceiver and oscillator around the controller as well, and check the chip marking matches before relying on the pinout for measurements.
