adt7301 preliminary technical data rev. prj | page 8 of 14 circuit information the adt7301 is a 13-bit digital temperature sensor with a 14 th bit that acts as a sign bit. the part houses an on-chip tempera- ture sensor, a 13-bit a/d converter, a reference circuit, and serial interface logic functions in sot-23 and msop packages. the a/d converter section consists of a conventional successive-approximation converter based around a capacitor dac. the parts are capable of running on a 2.7 v to 5.5 v power supply. the on-chip temperature sensor allows an accurate measure- ment of the ambient device temperature to be made. the specified measurement range of the adt7301 is ?40c to +150c. at +150c, the adt7301 is limited to 5% of its +55c operational lifetime. the structural integrity of the device starts to deteriorate when operated at voltage and temperature maximum specifications. converter details the conversion clock for the part is internally generated. no external clock is required except when reading from and writing to the serial port. in normal mode, an internal clock oscillator runs an automatic conversion sequence. during this automatic conversion sequence, a conversion is initiated every 1 second. at this time, the part powers up its analog circuitry and performs a temperature conversion. this temperature conversion typically takes 800 s, after which time the analog circuitry of the part automatically shuts down. the analog circuitry powers up again when the 1 second timer times out and the next conversion begins. the result of the most recent temperature conversion is always available in the serial output register because the serial interface circuitry never shuts down. the adt7301 can be placed in a shutdown mode via the con- trol register, in which case the on-chip oscillator is shut down and no further conversions are initiated until the adt7301 is taken out of shutdown mode. the adt7301 can be taken out of shutdown mode by writing all zeros into the control register. the conversion result from the last conversion prior to shut- down can still be read from the adt7301 even when it is in shutdown mode. in normal conversion mode, the internal clock oscillator is reset after every read or write operation. this causes the device to start a temperature conversion, the result of which is typically available 800 s later. similarly, when the part is taken out of shutdown mode, the internal clock oscillator is started and a conversion is initiated. the conversion result is available 800 s later, typically. reading from the device before a conversion is complete causes the adt7301 to stop converting; the part starts again when serial communication is finished. this read operation provides the previous result. temperature value register the temperature value register is a 14-bit read-only register that stores the temperature reading from the adc in 13-bit twos complement format plus a sign bit. the msb (db13) is the sign bit. the adc can theoretically measure a 255c temperature span. the internal temperature sensor is guaranteed to a low value limit of C40c and a high limit of +150c. the temperature data format is shown in table 5, which shows the temperature measurement range of the device (C40c to +150c). a typical performance curve is shown in figure 6. table 5. temperature data format temperature digital output db13db0 ?40c 11, 1011 0000 0000 ?30c 11, 1100 0100 0000 ?25c 11, 1100 1110 0000 ?10c 11, 1110 1100 0000 ?0.03125c 11, 1111 1111 1111 0c 00, 0000 0000 0000 +0.03125c 00, 0000 0000 0001 +10c 00, 0001 0100 0000 +25c 00, 0011 0010 0000 +50c 00, 0110 0100 0000 +75c 00, 1001 0110 0000 +100c 00, 1100 1000 0000 +125c 00, 1111 1010 0000 +150c 01, 0010 1100 0000 temperature conversion formula 1. positive temperature = adc code ( d )/32 2. negative temperature = ( adc code *( d ) C 16384)/32 *using all 14 bits of the data byte, includes the sign bit. negative temperature = ( adc code ( d )* C 8192)/32 *db13 (sign bit) is removed from the adc code digital output ?40c ?0.03125 c ?30c 11, 1111, 1111, 1111 11, 1100, 0100, 0000 11, 1011, 0000, 0000 temperature ( c) 75c 02884-0-006 150c 01, 0010, 1100, 0000 00, 1001, 0110, 0000 00, 0000, 0000, 0001 figure 12. temperature to digital transfer function

adt7301 preliminary technical data rev. prj | page 10 of 14 microprocessor interfacing the adt7301s serial interface allows for easy interface to most microcomputers and microprocessors. figure 14 through figure 17 show some typical interface circuits. the serial interface on the adt7301 consists of four wires: cs , 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 applic ation 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 three wires: sclk, cs , and dout. 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. adt7301 to mc68hc11 interface figure 14 shows an interface 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. the diagram shows the full (4-wire) interface. pc1 of the mc68hc11 is configured as an output and is used to drive the cs input. adt7301* sclk dout din mc68hc11* sclk miso mosi pc1 02884-0-008 *additional pins omitted for clarity cs figure 14. adt7301 to mc68hc11 interface adt7301 to 8051 interface an interface circuit between the adt7301 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 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 fi rst. 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. in the example shown, the adt 7301 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. for applications that require the adt7301s 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 shift data in and out with the fourth port line connecting to cs . port lines 1.0 through 1.3 (with p1.1 configured as an input) can be used to connect to sclk, dout, din, and cs , respectively, to implement this scheme. adt7301* 02884-0-009 sclk dout din 8051* p3.1 p3.0 p1.2 p1.3 *additional pins omitted for clarity cs figure 15. adt7301 to 8051 interface adt7301 to pic16c6x/7x interface figure 16 shows an interface circuit between the adt7301 and the pic16c6x/7x microcontroller. the pic16c6x/7x synchronous 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, port line ra1 is being used to generate the cs for the adt7301. adt7301* sclk dout din pic16c6x/7x* sck sdo sdi ra1 02884-0-010 *additional pins omitted for clarity cs figure 16. adt7301 to pic16c6x/7x interface the following software program shows how to program an pic16f873 to communicate with the adt7301. the pic16f873 is configured as an spi master with the porta.1 pin used as cs . any microchip microcontroller can use this program by simply exchanging the include file for the device thats being used.
