The CXD1185C is a high performance CMOS SCSI controller LSI that conforms to ANSIX3. 1311986 standards. The CXD1185C is capable of operating in both initiator and target modes. It satisfies all standard SCSI bus features, such as arbitration, selection and parity generation/check functions. A 24-bit data transfer byte counter and 16-byte FIFO are built into the hardware. Two separate buses for data and processor makes high speed data transfer possible. 48 mA (sinking) port is built-in to achieve reduction in the number of external components.
