PSD8XXF2/3/4/5
MCU BUS INTERFACE
The “no-glue logic” MCU Bus Interface block can
be directly connected to most popular MCUs and
their control signals. Key 8-bit MCUs, with their
bus types and control signals, are shown in Table
15. The interface type is specified using the PSD-
soft Express Configuration.
PSD8xxF2/3/4/5 Interface to a Multiplexed 8-Bit
Bus.
Figure 16 shows an example of a systemus-
ing a MCU with an 8-bit multiplexed bus and a
PSD8xxF2/3/4/5.
The
ADIO
port
on
the
PSD8xxF2/3/4/5 is connected directly to the MCU
address/data bus. Address Strobe (ALE/AS, PD0)
latches the address signals internally. Latched ad-
dresses can be brought out to Port A or B. The
PSD8xxF2/3/4/5 drives the ADIO data bus only
when oneof its internal resources is accessed and
Read Strobe (RD, CNTL1) is active. Should the
system address bus exceed sixteen bits, Ports A,
B, C, or D may be used as additional address in-
puts.
Table 15. MCUs and their Control Signals
Note: 1. Unused CNTL2 pin can be configured as CPLD input. Other unused pins (PC7, PD0, PA3-0) can be configured for other I/O func-
tions.
2. ALE/AS input is optional for MCUs with a non-multiplexed bus
