The 80960SB is a member of Intel’s i960® 32-bit processor family, which is designed especially for low cost
embedded applications. It includes a 512-byte instruction cache, an integrated floating-point unit and a built-in
interrupt controller. The 80960SB has a large register set, multiple parallel execution units and a 16-bit burst
bus. Using advanced RISC technology, this high performance processor is capable of execution rates in excess
of 5 million instructions per second*. The 80960SB is well-suited for a wide range of cost sensitive embedded
applications including non-impact printers, network adapters and I/O controllers.

80960SB
1.0 THE i960® PROCESSOR
The 80960SB is a member of the 32-bit architecture
from Intel known as the i960 processor family. These
microprocessors were especially designed to serve
the needs of embedded applications. The embedded
market includes applications as diverse as industrial
automation, avionics, image processing, graphics
and networking. These types of applications require
high integration, low power consumption, quick
interrupt response times and high performance.
Since time to market is critical, embedded micropro-
cessors need to be easy to use in both hardware and
software designs.
All members of the i960 processor family share a
common core architecture which utilizes RISC
technology so that, except for special functions, the
family members are object-code compatible. Each
new processor in the family adds its own special set
of functions to the core to satisfy the needs of a
specific application or range of applications in the
embedded market.
