The 80960KA is a member of Intel’s i960® 32-bit processor family, which is designed especially for embedded
applications. It includes a 512-byte instruction cache and a built-in interrupt controller. The 80960KA has a large
register set, multiple parallel execution units and a high-bandwidth burst bus. Using advanced RISC technology,
this high performance processor is capable of execution rates in excess of 9.4 million instructions per second*.
The 80960KA is well-suited for a wide range of applications including non-impact printers, I/O control and
specialty instrumentation.
