zopt2201 datasheet ? 2016 integrated device technology, inc 18 september 2 , 2016 3.5 conversion control state machine 3.5.1 start up after power - on or software reset the main state machine is set to start state during a power - on or software reset. as soon as the reset is released, the internal oscillator is started and the programmed i2c add ress and the trim values are read from the internal nvm trimming data block. the zopt2201 enters standby mode as soon as the idle state is reached (see figure 3 . 3 ). note: if the i2c address has not yet been read, t he device will respond with nack to any i2c command and ignore any request to avoid responding to an incorrect i2c address. if any of the sensor operation modes becomes activated through an i2c command (i.e., the ls_en bit is set to 1 and the sensor mode i s selected with the respective bits in the main_ctrl register), the internal support blocks are immediately powered on. once the voltages and currents are settled (typical after 500 s), the state machine checks for trigger events from a measurement schedul er to start conversions according to the selected measurement repeat rates (see section 3. 11.2 ). when the user resets the ls_en bit to 0, a running conversion will be completed and the relevant adcs and support blocks will move to standby mode thereafter. figure 3 . 3 main state machine r u n p o r s t a n d b y l s c o n v e r s i o n w a i t f o r r e p e a t l s _ m e a s _ r a t e l s _ e n l s _ e n ! l s _ e n l s i n a c t i v e s t a r t o s c i l l a t o r ! l s _ e n s t a r t o s c i l l a t o r s t o p o s c i l l a t o r r u n r e a d o u t n v m f u s e s l s i s e i t h e r a l s o r u v b s d e p e n d i n g o n t h e l s _ m o d e b i t
zopt2201 datasheet ? 2016 integrated device technology, inc 19 september 2 , 2016 3.6 light sensor sensitivity configuration 3.6.1 gain modes, resolution, and measurement time there are five ana log gain modes to adjust the sensitivity of the zopt2201 device to the needs of the application. the microcontroller can calculate the ambient light in lux by multiplying the adc count value of the als channel with the appropriate output - scaling coefficien t. a similar method can be used for uvi determination via uvbs channel. if als/uvbs_raw mode is used, temperature and stray light compensation must be carried out in the micro controller before output scaling coefficients are applied (see table 3 . 3 for the als/uvbs_raw mode description). selected analog gain settings as well as resolution and measurement time settings are valid for all active adc converter chan nels at the same time. the gain, resolution, and measure ment time cannot be simultaneously set to different settings for different channels. if different gain or resolution settings are required for different channels, conversions must be performed consecutively with modified se ttings. table 3 . 5 als detection ranges gain mode 1 gain mode 3 effective output resolution [bits] measurement time [ms] minimum detection [lux] maximum detection [lux] result resolution [lux/count] minimum detection [lux] maximum detecti on [lux] result resolution [lux/count] 13 3.125 19.2000 157286 19.2000 6.4000 52429 6.4000 16 25 2.4000 157286 2.4000 0.8000 52429 0.8000 17 50 1.2000 157286 1.2000 0.4000 52429 0.4000 18 (default) 100 0.6000 157286 0.6000 0.2000 52429 0.2000 19 200 0 .3000 157286 0.3000 0.1000 52429 0.1000 20 400 0.1500 157286 0.1500 0.0500 52429 0.0500 gain mode 6 gain mode 9 effective output resolution [bits] measurement time [ms] minimum detection [lux] maximum detection [lux] result resolution [lux/count] min imum detection [lux] maximum detection [lux] result resolution [lux/count] 13 3.125 3.2000 26214 3.2000 2.1333 17476 2.1333 16 25 0.4000 26214 0.4000 0.2667 17476 0.2667 17 50 0.2000 26214 0.2000 0.1333 17476 0.1333 18 (default) 100 0.1000 26214 0.1000 0.0667 17476 0.0667 19 200 0.0500 26214 0.0500 0.0333 17476 0.0333 20 400 0.0250 26214 0.0250 0.0167 17476 0.0167

zopt2201 datasheet ? 2016 integrated device technology, inc 22 september 2 , 2016 3.8 inte rrupt features the zopt2201 can generate an interrupt signal on a user - selected sensor channel. interrupts will be triggered if upper or lower threshold values are crossed or if the output count variation of consecutive conversions has exceeded a defined l imit. an interrupt can be displayed at the int pin as an active - low signal or via a status register flag. interrupt conditions are always evaluated after completion of a new conversion on the selected sensor channel. the ls_int signal (output of lsintgen in figure 3 . 5 ) is also stored in the main_status register as the ls interrupt status (see section 3.11.5 ) flag. the flag is cleared by reading the main_status register. a cleared ls interrupt status flag will also clear the interrupt signal on the int pin. figure 3 . 5 interrupt unit the interrupt is configured by the bits in the int_cfg register (see section 3.11.10 ). it can function as either threshold triggered ( ls_var_mode = 0) or variance trigged ( ls_var_mode = 1). the interrupt source generator is configurable to be one of the following input cha nnels: als or uvbs. the interrupt source is selected by the ls_int_sel bits in the int_cfg register (see section 3.11.10 ). l s _ i n t _ s e l i n t u n i t l s _ i n t l s _ i n t _ e n l s i n t g e n l s _ t h r e s _ u p l s _ t h r e s _ l o w l s _ t h r e s _ v a r l s _ p e r s i s t l s _ v a r _ m o d e l s i n t g e n 0 1 l s _ v a r _ m o d e l s _ t h r e s _ u p l s _ t h r e s _ l o w l s _ t h r e s _ v a r l s _ p e r s i s t + - - + + - | d i f f | d e c o d e l s _ i n t l s _ d a t a i n t p i n l s _ d a t a r e a d s t a t u s r e g o r l s _ i n i t l s _ i n t _ s t a t p e r s i s t r s r e s e r v e d 0 0 0 1 1 0 1 1 r e s e r v e d u v b c h a n n e l a l s c h a n n e l
zopt2201 datasheet ? 2016 integrated device technology, inc 23 september 2 , 2016 the threshold interrupt is enabled with ls_int_en = 1 and ls_var_mode = 0. the interrupt is set when the respective *_data register value of the selected interrupt source channel is above the upper or below the lower threshold configured in the ls_thres_up and ls_thres_low registers (see sections 3.11.12 and 3.11.13 respectively) for a specified number of consecutive measurements as configured in the int_pst register (1 + ls_persist ; see section 3.11.11 ). the v ariance interrupt is enabled with ls_int_en = 1 and ls_var_mode = 1. it is set when the absolute value difference between the preceding and the current output data of the selected interrupt source channel is above the decoded variance threshold (see s ectio n 3.11.14 ) for a specified number of consecutive measurements (1 + ls_persist ). 3.9 i2c interface the zopt2201 is equipped with an i2c interface for control and data communication. the chip always operates as a slav e. the device offers two different 7 - bit slave addresses that are selectable via nvm programming. a read/write bit must be appended to the slave address by the master device to properly communicate with the device. the interface is compatible with standard mode (100khz) and fast mode (400khz) i2c communication. table 3 . 7 supported i2c clock frequencies mode frequency transient noise filter standard 100khz 50ns fast 400khz 50ns the i2c circuitry is always act ive (standby or active mode of the zopt2201). if the i2c address is not yet read from the memory block, the device will respond with nack to any request and ignore the possible commands. an attempt to read or write to non - existing addresses will be answe red with nack. 3.9.1 i2c address decoding the i2c address decoding is done during start up after a power - on - reset or software reset. two different i2c addresses can be selected through nvm programming (see table 3 . 8 ). table 3 . 8 i2c address address nvm level i2c address 7 bits write read 0 C default 1010 011x bin a6 hex a7 hex 1 C programmed 1010 010x bin a4 hex a5 hex 3.9.2 i2c register read the zopt2201 registers can be read i ndividually or in block read mode. when two or more bytes are read in block read mode, reserved register addresses are skipped and the next valid address is referenced. if the last valid address has been reached, but the master continues with the block rea d, the address counter in the zopt2201 will not roll over and the zopt2201 returns 00 hex for every subsequent byte read. the block read operation is the only way to ensure correct data read out of multi - byte registers and to avoid splitting of results with high and low bytes originating from different conversions. during block read access on ls result registers, the result update is block ed. if a read access is started on an address belonging to a non - readable register, the zopt2201 will return nack until t he i 2 c operation is ended. read operations must follow the timing diagram in figure 3 . 6 .
