ams datasheet page 9 [v1-01] 2016-jun-17 document feedback AS6200 ? detailed descriptions data width, bit d4 for AS6200 only the 12 bit mode is supported by the device, which means that the dw should always be set to 0. alert, bit d5 the alert bit can be used to easily compare the current temperature reading to the thresholds that can be set in the tlow and thigh registers. if the polarity bit is set to 0, the al bit is read as 1 until the converted temperature value exceeds the defined value in the high temperature threshold register thigh for the number of defined consecutive faults (bits cf). such an event causes the al bit to toggle to 0 and the va lue is kept until the converted temperature value falls below the defined value in the low temperature threshold register tlow for the number of defined consecutive faults. if this condition is met, the al bit is reset to 1. the polarity bit (pol) defines the active state of the alert bit as depicted in the following figure. the alert bit has the same setting as the alert output as long as the device is configured for the comparator mode. figure 13: state diagram of the alert bit conversion rate, bit d6-d7 the conversion rate bits defi ne the number of executed temperature conversions per time unit. additional readouts of the temperature register between conversion is possible but not recommended because the value is changed only after a conversion is finished. values of 125ms, 250ms, 1s and 4s per conversion can be configured while the default rate is set to 250ms. this corresponds to a value of 4 conversions per second. al = 1 al = 0 t > thigh for n consecutive cycles t < tlow for n consecutive cycles pol = 0: al = 0 al = 1 t > thigh for n consecutive cycles t < tlow for n consecutive cycles pol = 1:

ams datasheet page 11 [v1-01] 2016-jun-17 document feedback AS6200 ? detailed descriptions sleep mode, bit d8 the sleep mode is activated by setting the bit sm in the configuration register to 1. this shuts the device down immediately and reduces the power consumption to a minimum value. the serial interface is the only active circuitry in the sleep mode in order to provide access to the digital registers. after resetting the sm bit to 0, the device enters the continuous conversion mode. figure 16: sleep mode configuration interrupt mode, bit d9 the interrupt mode bit defines whether the device operates in the temperature comparator mode or interrupt mode. this defines the operation mode of the alert output as described in the polarity bit section. figure 17: interrupt mode configuration the comparator mode is characterized that if the temperature value exceeds the thigh value, the alert output is changed (e.g. from high to low if the polarity bit is set to 0 and vice versa). the alert output stays in that condition until the measured temperature drops below the defined tlow value. the interrupt mode is characterized that it changes the alert output as soon as the measured temperature crosses the thigh or tlow value threshold. the alert bit has the same setting as the alert output if the device is set to comparator mode. sm bit operation mode 0 continuous conversion mode 1sleep mode im bit operation mode 0 comparator mode 1 interrupt mode

ams datasheet page 13 [v1-01] 2016-jun-17 document feedback AS6200 ? detailed descriptions consecutive faults, bits d11-d12 a fault condition persists if the measured temperature either exceeds the configured value in register thigh or falls below the defined value in register tlow. as a result, the alert pin indicates the fault condition if a defined number of consecutive temperature readings meets this fault condition. the number of consecutive faults are define d with two bits (d12 and d11) and prevent a false alert if environmental temperature noise is present. the register configuration is shown in the following table. figure 20: consecutive faults bit settings single shot conversion, bit d15 the device features a single shot measurement mode if the device is in sleep mode (sm=1). by setting the single shot-bit to 1, a single temperature conversion is started and the ss-bit can be read as 1 during the active conversion operation. once the conversion is completed, the device enters the sleep mode again and the ss-bit is set to 0. the single shot conversion allows very low power consumption since a temperature conversion is executed on demand only. this allows a user defined timing of the temperature conversions to be executed and is used if the consecutive operation mode is not required. as the device exhibits a very short conversion time, the effective conversion rate can be increased by setting the single shot bit repetitively after a conversion has finished. however, it has to be ensured that the additional power is limited, otherwise self-heating effects have to be considered. figure 21: single shot conversion bit settings cf bits consecutive faults (n) d12 d11 00 1 01 2 10 4 11 6 ss bit conversion 0 no conversion ongoing/conversion finished 1 start single shot conversion /conversion ongoing
page 14 ams datasheet document feedback [v1-01] 2016-jun-17 AS6200 ? detailed descriptions high- and low-limit registers if the comparator mode is configured (im=0), the alert output becomes active if the temperature equals or exceeds the defined value in register thigh for the configured number of consecutive faults (n). this conf iguration is defined by the field cf in the configuration regist er. the alert output remains assigned until the converted temperature value equals or falls below the defined value in register tlow for the same number of consecutive fault cycles. if the interrupt mode is configured (im=1), the alert output becomes active if the temperature equals or exceeds the defined value in register thigh for the configured number of consecutive fault cycles. it remains active until a read operation is executed on any register. the alert output is also cleared if the device is set into sleep mo de by setting bit sm in the configuration register. once the alert output is cleared, it is activated again only if the temperature value falls below the configured value in register tlow. it remains active unless a read operation has taken place. this sequence is repeated un less the device is set into the comparator mode or reset by the general call reset command. this reset command clears the interrupt mode bit and consequently puts the device into the comparator mode. the sequential behavior is summarized in the following figure.

page 18 ams datasheet document feedback [v1-01] 2016-jun-17 AS6200 ? detailed descriptions serial interface the device employs a standard i2c-interface. bus description a data transfer must be invoked by a master device (e.g. microcontroller) which defines the access to the slave device. the master device defines and generates the serial clock (scl) and the start/stop conditions. in order to address a specific device, a start condition has to be generated by the master device by pulling the data line (sda) from a logic high level to a logic low level while the serial clock signal (scl) is kept at high level. after the start condition, the sl ave address byte is transmitted which is completed with a nint h bit which indicates a read (bit=1) or a write operation (bit=0) respectively. all slaves read the data on the rising edge of the clock. an acknowledge signal is generated by the a ddressed slave during the ninth clock pulse. this acknowledge signal is produced by pulling the pin sda to a low level by the selected slave. subsequently, the byte data transfer is started and finished by an acknowledge bit. a change in the data signal (sda) while the clock signal (scl) is high causes a start or stop condition. hence, it must be ensured such a condition is prevented during a data transfer phase. after completing the data transfer, the master generates a stop condition by pulling the data line (sda) from low level to high level while the clock signal (scl) is kept at high level. data interface a bus connection is created by connecting the open drain input/output lines sda and scl to the two wire bus. the inputs of sda and scl feature schmitt-trigger inputs as well as low pass filters in order to suppress noise on the bus line. this improves the robustness against spikes on the two wire interface. both fast transmission mode (1 khz to 400khz) and high-speed transmission mode (1khz to 3.4mhz) are employed to cover different bus speed settings. any data transfer transmits the msb first and the lsb as last bit.
ams datasheet page 19 [v1-01] 2016-jun-17 document feedback AS6200 ? detailed descriptions bus address a slave address consists of seven bits, followed by a data direction bit (read/write operation). the slave address can be selected from a pool of two different address settings by connecting the input pin add0 to an appropriate signal as summarized in the following table. the add0 must not be left unconnected. figure 27: i2c address select configuration read/write operation in order to access an internal data register, the index register must be written in advance. this register contains the actual register address and selects the appropriate register for an access. a typical transfer consists of the transmission of the slave address with a write operation indication, followed by the transmission of the register address and is finalized with the actual register content data tr ansfer. this implies that every write operation to the temperature sensor device requires a value for the index register prior to the transmission of the actual register data. the index register defines the regi ster address for both the write and read operation. consequent ly, if a read operation is executed, the register address is taken from the index register which was defined from the last write operation. if a different register needs to be read, the index register has to be written in advance to define the new register address. this is accomplished by transmitting the slave address with a low r/w bit, followed by the new content of the index register. subsequently, the master provokes a start condition on the bus and transmits the slave address with a high r/w bit in order to initiate a read operation. since the index register always keeps its last value, reads can be executed repetitively on the same register. similarly to the byte transfer wh ere the msb is transmitted first, the transfer of a 16-bit word is executed by a two byte transfer whereas the msb byte is always transmitted first. add0 connection device address (bin) device address (hex) vss 100 1000 0x48 vdd 100 1001 0x49
page 20 ams datasheet document feedback [v1-01] 2016-jun-17 AS6200 ? detailed descriptions slave operation the device employs a slave functionality only (slave transmitter and slave receiver) and cannot be operated as a bus master. consequently, the device never actively drives the scl line. slave receiver mode any transmission is invoked by the master device by transmitting the slave address with a low r/w bit. subsequently, the slave device acknowledges the reception of the valid address by pulling the ninth bit to a low level. following to acknowledge, the master transmits the content of the index register. this transfer is again acknowledged by the slave device. the next data byte(s) are written to the actual data register which is selected by the index register while each transfer is acknowledged upon a completed transfer by the slave device. a data transfer ca n be finished if the master transmits a start or a stop condition on the bus. slave transmitter mode the master transmits the slave a ddress with a high r/w bit. in turn, the slave acknowledges a valid slave address. subsequently, the slave transmit s the msb byte of the actual selected data register by the index register. after the msb byte transmission, acknowledge is sent by the master. afterwards, the lsb byte is transmitted by the slave which is also acknowledged by the master after the completed transmission. the data transfer can be terminated by the master by transmitting a not-acknowledge after the transmitted slave data or by invoking a start or a stop condition on the bus. alert function if the device is configured for an interrupt mode operation (im=1), the alert output can be used as an alert signal. if the polarity bit is set to 0 (p ol=0), the alert condition bit is set to 0 in case the temperature has exceeded the configured value in register thigh. accordin gly, the alert condition bit is set to 1 if the temperature has fallen below the configured value in register tlow. if the polarity bit is set to 1 (p ol=1), the alert condition bit is inverted. the following table summarizes the status of the alert condition bit with different alert conditions and polarity configurations.
ams datasheet page 21 [v1-01] 2016-jun-17 document feedback AS6200 ? detailed descriptions figure 28: alert condition bit general call a general call is issued by the master by transmitting the general call address (000 0000) with a low r/w bit. the slave device acknowledges the general call address and responds to commands in the second byte. if the master transmits a value of 0000 0110 as a second byte, the device is reset and all registers are initialized with their default values. in contrast to the general call address, the general address acquire command is not supported. high speed mode the bus operation is limited to 400khz unless a high speed command is issued by the master device as the first byte after a start condition. this switches the bus to a high speed operation which allows data transfer frequencies up to 3.4mhz. such a command is not acknowledged by the slave but the input filter time constants on the serial interface (sda and scl) are adapted to allow the higher transfer rate. after a high speed command, the slave address is transmitted by the master in order to invoke a data transfer. the bus keeps operating at the higher operating frequency until the master issues a stop condition on the serial bus. upon the reception of the stop condition by the slav e, the input filters are switched to their initial time constants which allow lower transfer rates only. pol alert condition alert condition bit (ac-bit) 0t thigh 0 0t tlow 1 1t thigh 1 1t tlow 0
