Detailed Description

Dual-channel Ultra320 SCSI controller IC for PCI-X host systems. Specialized IC used to connect and control Ultra320 SCSI storage devices with high throughput and low latency. Revision A2 in a T-series BGA package. Category: Integrated Circuits (ICs). Classification: Specialized ICs. In-stock quantity: 2540 units. Date code: 11+.

Key Features

Dual-channel Ultra320 SCSI, supports two independent SCSI buses

High-speed PCI-X host interface (64-bit, designed for 133 MHz environments)

Backward compatibility with earlier SCSI generations (Ultra160, Ultra2, Wide SCSI; LVD with SE fallback where supported)

Integrated SCSI protocol engine with scatter-gather DMA for efficient data transfers

Hardware assist for command queuing and bus arbitration to reduce CPU load

Mature firmware/BIOS ecosystem and broad OS driver support across legacy platforms

Proven interoperability with a wide range of U320 drives, backplanes, and enclosures

Designed for server-grade reliability and continuous operation

Key Advantages

High bandwidth per channel for demanding storage workloads

Stable, field-proven controller widely used in enterprise servers and HBAs

Excellent compatibility for legacy systems that require U320 SCSI

Reduces host CPU utilization with efficient DMA and offload features

Ideal for maintaining and upgrading existing U320 SCSI infrastructures

Packaging

Package type: BGA (T-series PBGA), high pin-count array optimized for signal integrity

Package / Case code: 869 (manufacturer package designation)

Material: Molded PBGA with organic substrate for good thermal and electrical performance

Size: Standard PBGA footprint for this device class; see datasheet for exact dimensions and land pattern

Pin configuration: High-density ball grid array including PCI-X bus interface, two SCSI channel interfaces, JTAG, clock, reset, and dedicated power/ground balls (full pin map in datasheet)

Thermal characteristics: Commercial-grade operating range with recommended airflow; use proper heatsinking/air movement in dense server designs (refer to datasheet for thermal guidelines and θJA)

Electrical properties: Designed for 3.3 V PCI-X signaling; separate core and I/O rails typical for this device class; follow decoupling and power integrity recommendations in the datasheet

Lifecycle

Status: Legacy product; many variants have reached end-of-life or are not recommended for new designs. Availability is primarily from existing inventory and specialized distributors.

Direct equivalents or close alternatives:

- LSI53C1030 (other package/revisions)

- LSI53C1030D (revision variant, check pinout and firmware differences)

- LSI53C1020 (single-channel Ultra320 SCSI controller)

- Adaptec AIC-7902 (dual-channel U320 SCSI controller; not drop-in compatible, but similar function)

- Functional migration options (not drop-in): LSI/Broadcom SAS controllers such as SAS1068E or SAS2008 when moving to SAS/SATA ecosystems
