1.5.6 Reliability
The following features enhance the reliability of the LSI53C896:
•
2 kV ESD protection on SCSI signals.
•
Protection against bus reflections due to impedance mismatches.
•
Controlled bus assertion times (reduces RFI, improves reliability, and
eases FCC certification).
•
Latch-up protection greater than 150 mA.
•
Voltage feed-through protection (minimum leakage current through
SCSI pads).
•
More than 25% of pins are power and ground.
•
Power and ground isolation of I/O pads and internal chip logic.
•
TolerANT technology provides:
– Active negation of SCSI Data, Parity, Request, and Acknowledge
signals for improved fast SCSI transfer rates.
– Input signal filtering on SCSI receivers improves data integrity,
even in noisy cabling environments.
1.5.7 Testability
The following features enhance the testability of the LSI53C1010:
•
All SCSI signals accessible through programmed I/O.
•
SCSI loopback diagnostics.
•
SCSI bus signal continuity checking.
•
Support for single step mode operation.
•
JTAG boundary scan.
