Description



Features:

• Satisfies all SCSI bus features, including arbitration, selection,
   parity generation/check and synchronous data transfer.
• Maximum synchronous data transfer rate of 4.0 MB/s
   and maximum asynchronous data transfer rate of 2.5 MB/s.
• Provides two separate ports for the data bus andthe CPU bus.

Description

The CXD1185CR is a high performance CMOS SCSI controller LSI that conforms to ANSIX3. 131- 1986 standards. The CXD1185CR 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 CXD1185CR 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.

The chip CXD1185CR offers a set of high level commands at SCSI phase level. It is also possible to read/write all individual SCSI signals. The combination of the above two makes programs simpler and at the same time improves programmability.
