MICROPROCESSOR INTERFACING  
The ADT7302’s serial interface allows for easy interface to most  
microcomputers and microprocessors. Figure 14 through  
Figure 17 show some typical interface circuits. The serial  
In the example shown, the ADT7302 is connected to the serial  
port of the 8051. Because the serial interface of the 8051  
contains only one data line, the DIN line of the ADT7302 is tied  
low in the interface example given in Figure 15.  
CS  
interface on the ADT7302 consists of four wires: , DIN,  
DOUT and SCLK. All interface circuits shown utilize all four  
interface lines. However, it is possible to operate the interface  
with three wires. If the application does not require the power-  
down facility offered by the ADT7302, the DIN line can be tied  
permanently low. Thus, the interface can be operated from just  
For applications that require the ADT7302’s power-down  
feature, the serial interface should be implemented using data  
port lines on the 8051. This allows a full-duplex serial interface  
to be implemented. The method involves “bit-banging” a port  
line to generate a serial clock while using two other port lines to  
CS  
three wires: SCLK, , and DOUT.

Port lines 1.0 through 1.3 (with P1.1 configured as an input)  
The serial data transfer to and from the ADT7302 requires a 16-  
bit read operation. Many 8-bit microcontrollers have 8-bit serial  
ports, and this 16-bit data transfer is handled as two 8-bit trans-  
fers. Other microcontrollers and DSP processors transfer 16 bits  
of data in a serial data operation.  
CS  
can be used to connect to SCLK, DOUT, DIN, and  
respectively, to implement this scheme.

Figure 14 shows an interface between the ADT7302 and the

master mode with its CPOL and CPHA bits set to a Logic 1.  
When the MC68HC11 is configured like this, its SCLK line  
idles high between data transfers. Data is transferred to and  
from the ADT7302 in two 8-bit serial data operations. The

An interface circuit between the ADT7302 and the microcon-  
troller is shown in Figure 15. The 8051 is configured in its Mode  
0 serial interface mode. The serial clock line of the 8051 (on  
P3.1) idles high between data transfers. Data is transferred to  
and from the ADT7302 in two 8-bit serial data operations. The  
ADT7302 outputs the MSB of its data stream as the first valid  
bit while the 8051 expects the LSB first. Thus, the data read into  
the serial buffer needs to be rearranged before the correct data-  
word from the ADT7302 is available in the accumulator.
