SYM201F40 Data Sheet
SYM201F40
Ultra2 SCSI Hard Disk Controller
The SYM201F40 is the industry’s first hard disk
drive controller with Ultra2 SCSI support. It
provides industry-leading performance of 80 MB/s
SCSI transfer rate, 140 MB/s burst buffer
bandwidth, and 40 MB/s disk transfer rate. High
data integrity is provided from SCSI through the
buffer to disk. All buffer data, including tables, is
protected by parity, VRC, or CRC.
The SYM201F40 is comprised of a SCSI Protocol
Controller, Host DMA/Multi-Context Engine,
Buffer Manager, Disk Formatter, Data ECC, and
Microprocessor Interface. Each major block is
designed with Symbios Logic’s core methodology
to facilitate integration with other logic, such as
customer ASIC logic, microprocessor, servo/spin
functions, or embedded memory.
The SYM201F40 is available in a 176-pin TQFF
package and supports greater device connectivity
and longer cables with Low Voltage Differential
(LVD). This allows transfers over distances that
once required differential SCSI and the added
expense of external transceivers. Backward
compatibility is supported with Symbios Logic
LVDlink universal I/O transceivers that allow the
device to switch between LVD and single-ended
mode.
