Preliminary Technical Data

MICROPROCESSOR INTERFACING

The ADT7301’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 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 the interface example given in Figure 15.

interface on the ADT7301 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 ADT7301, the DIN line can be tied

permanently low. Thus, the interface can be operated from just

For applications that require the ADT7301’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

three wires: SCLK, , and DOUT.

shift data in and out with the fourth port line connecting to

Port lines 1.0 through 1.3 (with P1.1 configured as an input)

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 trans-

fers. Other microcontrollers and DSP processors transfer 16 bits

of data in a serial data operation.

When the MC68HC11 is configured like this, its SCLK line

idles high between data transfers. Data is transferred to and

An interface circuit between the ADT7301 and the microcon-

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.

The following software program shows how to program an

program by simply exchanging the include file for the device
