2.4.3 Processor mode application examples
(1) Application example of memory expansion in the case where the
ONW
(One-Wait)
function is not used
Outline
:
The external memory is accessed in the microprocessor mode.
At f(X
IN
) = 8 MHz, an available RAM is given by the following :
OE
access time : ta (OE)
50 ns
Setup time for writing data : tsu (D)
65
ns
For example, the M5M5256BP-10 whose address access is 100 ns is available.
Figure 2.4.3 shows an expansion example of a 32K byte ROM and a 32K byte RAM.
