(3) Example of usage -3

Figure 3.6.3 is an example in which an external memory is connected to the

TMP93CS40. In this example, a 128-Kbyte ROM is connected using a 16-bit bus, and a

256-Kbyte RAM is connected using a 16-bit bus.

Figure 3.6.3 Example of External Memory Connection (ROM & RAM

= 16 bits)

The TMP93CS40 has built-in ROM and RAM. When ROM and RAM have

insufficient capacity, it is possible to connect an external memory following the usage

examples for this purpose. In this example, the memory configuration is as follows.
