This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
PSD Interface to a Non-Multiplexed, 16-bit Bus
Figure 20 shows an example of a system using an
MCU with a 16-bit, non-multiplexed bus and a
PSD4256G6V. The address bus is connected to
the ADIO Port, and the data bus is connected to
Ports F and G. Ports F and G are in tri-state mode
when the PSD is not accessed by the MCU.
Should the system address bus exceed sixteen
bit, Ports A, B, or C may be used for additional ad-
dress inputs.
