LSI53C876 Benefits 1-7
1.3.4 Integration
The LSI53C876 contains these integration features:
•
Dual channel SCSI multifunction controller.
•
3.3 V/5 V PCI interface.
•
Full 32-bit PCI DMA bus master.
•
Memory-to-Memory Move instructions allow use as a third-party PCI
bus DMA controller.
•
High-performance SCSI core.
•
Integrated SCRIPTS processor.
1.3.5 Reliability
The LSI53C876 contains these reliability features:
•
2 kV ESD protection on SCSI signals.
•
Typical 300 mV SCSI bus hysteresis.
•
Protection against bus reflections due to impedance mismatches.
•
Controlled bus assertion times (reduces EMI, improves reliability, and
eases FCC certification).
•
Latch-up protection greater than 150 mA.
•
Voltage feed-through protection (minimum leakage current through
SCSI pads).
•
Power and ground isolation of I/O pads and internal chip logic.
•
TolerANT technology, which 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.
