Frequently Asked Questions
How much memory space can the 24-bit address bus support?
A 24-bit address bus can represent 16 MB of address space, subject to the processor mode, chipset design, and memory-mapping implementation.
Will IS80C286-20 fit an existing 68-lead processor socket?
The device uses a PLCC-68 package with 68 leads, but buyers must compare the N68.95 package drawing, orientation, and complete pinout before substitution.
Which legacy-system details should procurement verify before replacing another 80286 device?
Confirm the 20 MHz speed grade, 16-bit data bus, 24-bit address bus, PLCC-68 pinout, voltage requirements, temperature grade, and software compatibility.
