Answer 1

Answer #1

Solution:

The EPROM with size 64KB has 16 Address lines (A15 - A0) and 8 data lines.

Address range = 0x0000 to 0xFFFF.

Base Address of the EPROM is 0x40000

Address range of EPROM with Base Address 0x40000 is in the range from 0x40000 to 0x4FFFF.

Address decoder has input address range from A16, A17 and A18 Address lines.

EPROM address lines are A15 - A0.

Partial address decoder is dsigned as

A18 = 1 A17 = 0 and A16 =0.
