80960CA-33, -25, -16

32-bit demultiplexed and pipelined burst bus

1.0 PURPOSE

provides a 132 Mbyte/s bandwidth to a system’s

high-speed external memory sub-system. In

addition, the 80960CA’s on-chip caching of instruc-

tions, procedure context and critical program data

substantially decouple system performance from the

wait states associated with accesses to the system’s

slower, cost sensitive, main memory subsystem.

This document provides electrical characteristics for

the 33, 25 and 16 MHz versions of the 80960CA. For

a detailed description of any 80960CA functional

topic—other than parametric performance—consult

the 80960CA Product Overview (Order No. 270669)

or the i960 CA Microprocessor User’s Manual

(Order No. 270710). To obtain data sheet updates

and errata, please call Intel’s FaxBACK data-on-

demand system (1-800-628-2283 or 916-356-3105).

Other information can be obtained from Intel’s tech-

nical BBS (916-356-3600).

The 80960CA bus controller integrates full wait state

and bus width control for highest system perfor-

mance with minimal system design complexity.

Unaligned access and Big Endian byte order support

reduces the cost of porting existing applications to

the 80960CA.

2.0 80960CA OVERVIEW

The processor also integrates four complete data-

chaining DMA channels and a high-speed interrupt

controller on-chip. DMA channels perform: single-

cycle or two-cycle transfers, data packing and

unpacking and data chaining. Block transfers—in

addition to source or destination synchronized trans-

fers—are provided.

The 80960CA is the second-generation member of

the 80960 family of embedded processors. The

80960CA is object code compatible with the 32-bit

80960 Core Architecture while including Special

Function Register extensions to control on-chip

peripherals and instruction set extensions to shift 64-

bit operands and configure on-chip hardware.

Multiple 128-bit internal buses, on-chip instruction

caching and a sophisticated instruction scheduler

allow the processor to sustain execution of two

instructions every clock and peak at execution of

three instructions per clock.

The interrupt controller provides full programmability

of 248 interrupt sources into 32 priority levels with a

typical interrupt task switch (”latency”) time of

750 ns.
