Interfacing the 80C286-16 with the 80287-10 TM
Interfacing the 80C286-16 with the 80287-10
Application Note March 1997 AN120.1
Introduction
An important requirement in many systems is the ability to 80287 with a 1/3 duty cycle to allow the 80287-10 to run at
off-load numeric data processing. In an 80C286 system, this it’s full 10MHz capability. One solution for providing this clock
can be accomplished with an 80287 numeric co-processor. is the 82C84A-1, which meets this specification with either a
However, as processor speeds increase, it may become 3
