MICROPROCESSOR INTERFACING OF THE AD7545
The AD7545 can directly interface to both 8- and 16-bit micro-
processors via its 12-bit wide data latch using standard CS and
WR control signals.
A typical interface circuit for an 8-bit processor is shown in
Figure 11. This arrangement uses two memory addresses, one
for the lower eight bits of data to the DAC and one for the up-
per four bits of data into the DAC via the latch.

Figure 11. 8-Bit Processor to AD7545 Interface
Figure 12 shows an alternative approach for use with 8-bit
processors which have a full 16-bit wide address bus such as
6800, 8080, Z80 This technique uses the 12 lower address lines
of the processor address bus to supply data to the DAC, thus
each AD7545 connected in this way uses 4k bytes of address
locations. Data is written to the DAC using a single memory
write instruction. The address field of the instruction is orga-
nized so that the lower 12 bits contain the data for the DAC and
the upper 4 bits contain the address of the 4k block at which the
DAC resides.
