ADT7301  
APPLICATIONS INFORMATION  
MICROPROCESSOR INTERFACING  
In the example shown in Figure 16, the ADT7301 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 ADT7301  
is tied low in Figure 16.  
The ADT7301 serial interface allows easy interface to most  
microcomputers and microprocessors. Figure 15 to Figure 18  
show some typical interface circuits. The serial interface on the  
CS  
ADT7301 consists of four wires: , DIN, DOUT, and SCLK.  
For applications that require the ADT7301 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 generating a serial clock on  
one port line while using two other port lines to shift data  
All interface circuits shown use 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 ADT7301, the DIN line can be tied low permanently.  
Thus, the interface can be operated from just three wires: SCLK,  
CS  
in and out with the fourth port line connecting to . Port  
CS  
, and DOUT.  
lines 1.0 to 1.3 (with P1.1 configured as an input) can be used  
CS  
to connect to SCLK, DOUT, DIN, and , respectively, to  
implement this scheme.  
The serial data transfer to and from the ADT7301 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  
transfers. Other microcontrollers and DSP processors transfer  
16 bits of data in a serial data operation.

ADT7301-to-MC68HC11 Interface  
Figure 15 shows an interface circuit between the ADT7301 and  
the MC68HC11 microcontroller. The MC68HC11 is configured  
in 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  
ADT7301 in two 8-bit serial data operations. Figure 15 shows  
the full (4-wire) interface. PC1 of the MC68HC11 is configured

input.  
Figure 17 shows an interface circuit between the ADT7301 and  
the PIC16C6x/7x microcontroller. The PIC16C6x/7x synchro-  
nous serial port (SSP) is configured as an SPI master with the  
clock polarity bit set to a Logic 1. In this mode, the serial clock  
line of the PIC16C6x/7x idles high between data transfers. Data  
is transferred to and from the ADT7301 in two 8-bit serial data  
operations. In the example shown in Figure 17, port line RA1 is

Figure 16 shows an interface circuit between the ADT7301 and  
the microcontroller. 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  
ADT7301 in two 8-bit serial data operations. The ADT7301  
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 ADT7301 is available in the accumulator.
