i960 Processor Family Features and Benefits
i960
Processor Family Overview
Intel’s i960 processors offer a broad line-up
of code-compatible products for fast time-to-
market. The product family consists of high-
performance, 32-bit embedded RISC
processors supported by an outstanding
selection of development tools.
The i960 family can deliver this range of price
and performance alternatives because it was
designed for the extreme flexibility required by
today’s imaging, storage and networking
applications. The i960 HA/HD/HT and i960
CA/CF processors are superscalar
implementations and are able to execute
multiple instructions per clock cycle. The
i960 JT-100 Mini-PBGA package enables high
densities ideal for space-constrained
applications such as remote access, XDSL and
hubs. The i960 KA/KB processors deliver high-
performance with inexpensive DRAM memory
subsystems. The i960 SA/SB processors are
ideal for cost-sensitive designs.
The entire line is code-compatible offering a
wide range of performance options, giving
developers an easy migration path while pre-
serving investments in existing hardware and
software. It is a time-proven and excellent
choice for local and wide-area networking,
storage, telecom and imaging applications.

SELECTION.
Offers the ability to scale products across a wide
range of price and performance levels while preserving existing
software and minimizing development time
COMPATIBILITY.
Same instruction set from lowest to highest
performance processor
INTEGRATION.
Increased throughput by having the processor,
the PCI bus, and the memory controller on one chip resulting
in cost, boardspace and power savings.
