Wide Fast-20 SCSI Protocol Controller With PCI Interface
MB86606 s DESCRIPTION
The MB86606 is an intelligent SCSI Protocol Controller (SPC) which plies with ANSI (FAST-20) standard and integrates a PCI local bus interface function. The specification of SCSI controller block is based on the MB86605’s one which is a Wide SCSI-2 protocol controller, with addition of some enhancements such as Fast-20 (ultra-SCSI) support and larger "Data Register FIFO" (512 bytes). The MB86606 is capable of transfering data up to 40 Mbyte/sec. As for the SCSI bus pins, a totem pole type single-ended driver/receiver is incorporated in the device so that it can drive the SCSI bus directly. Furthermore, the MB86606 is capable of connecting the external differential type driver/receiver.
The SCSI bus sequence is controlled by mands issued via the system interface. So, it supports sequential mands that perform the phase-to-phase sequences to reduce the overhead of system’s sequence operations.
As another key feature to reduce the system overhead, the device has a 2 Kbytes user program memory to store the user program with the mands. Due to this, all the SCSI bus sequences including the data transfer can be performed automatically.
As the system interface block, it incorporates a 32-bit PCI local bus interface which makes MB86606 an Ideal "on-board PCI-SCSI controller" as well as Host/RAID controllers for PCs, servers and work stations. It also supports 16-bit separate MPU and DMA buses. For the on-chip PCI bus interface, the MB86606 also incorporates a 32-bit DMA controller that is capable of supporting the scatter-gather function so that the data transfers can be controlled by both user program and the host system.
The device is fabricated by the advanced CMOS process and is housed in an 144-pin plastic Low Profile Shrink Quad Flat Package (Suffix: -PMT). s PACKAGE
