required. Fast SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160 SCSI are all
supported by the SYM53C1010R.
An on-chip SCSI clock quadrupler allows the chip to achieve Ultra160 SCSI
transfer rates with an input frequency of 40 MHz. The 8 KB of internal RAM
per channel for SCRIPTS
instruction storage allow all accesses to remain internal,
reducing the time spent on the PCI bus. A 944-byte DMA FIFO on each channel
allows the device to efficiently burst up to 512 bytes across the PCI bus. SCSI
bus phase mismatches are handled in SCRIPTS, reducing CPU utilization.
