S1D13708 Interfacing to 8-bit Processors

2 Interfacing to an 8-bit Processor
2.1 The Generic 8-bit Processor System Bus
Although the S1D13708 does not directly support an 8-bit CPU, an 8-bit interface can be
achieved with minimal external logic.
Typically, the bus of an 8-bit microprocessor is straight forward with minimal CPU and
system control signals. To connect a memory mapped device such as the S1D13708, only
the write, read, and wait control signals, plus the data and address lines, need to be inter-
faced. Since the S1D13708 is a 16-bit device, some external logic is required.
