2 Optical ensor LTR-329L-0. Description The LTR-329L-0 is a low voltage I2 digital light sensor [L] in a low cost miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal capable of direct I 2 interface. It provides a linear response over a wide dynamic range from 0.0 lux to 64k lux and is well suited to applications under high ambient brightness. There are altogether six gain settings (X, 2X, 4X, 8X, 48X and 96X) available for user to configure. This MO design and factory-set one time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability to the end customers. 2.

15 Optical ensor LTR-329L-0 L_ONTR Register (0x80) The L_ONTR register controls the L Gain setting, L operation modes and software (W) reset for the sensor. The L sensor can be set to either standby mode or active mode. t either of these modes, the I 2 circuitry is always active. The default mode after power up is standby mode. During standby mode, there is no L measurement performed but I 2 communication is allowed to enable read/write to all the registers 0x80 L_ONTR (default = 0x00) B7 B6 B5 B4 B3 B2 B B0 Reserved L Gain W Reset L Mode Field Bits Default Type Description Reserved 7: Gain X lux to 64k lux (default) 00 Gain 2X 0.5 lux to 32k lux 00 Gain 4X 0.25 lux to 6k lux L Gain 4:2 000 RW 0 Gain 8X 0.25 lux to 8k lux 00 Reserved 0 Reserved 0 Gain 48X 0.02 lux to.3k lux Gain 96X 0.0 lux to 600 lux 0 Initial start-up procedure is NOT started (default) W reset 0 RW Initial start-up procedure is started, bit has default value of 0 after start-up L mode 0 0 RW 0 tand-by mode (default) ctive mode
16 Optical ensor LTR-329L-0 L_ME_RTE Register (0x85) The L_ME_RTE register controls the integration time and timing of the periodic measurement of the L in active mode. L Measurement Repeat Rate is the interval between L_DT registers update. L Integration Time is the measurement time for each L cycle. L Integration Time must be set to be equal or smaller than the L Measurement Repeat Rate. If L Integration Time is set to be bigger than L Measurement Repeat Rate, it will be automatically reset to be equal to L Measurement Repeat Rate by the I internally. 0x85 L_ME_RTE (default = 0x03) B7 B6 B5 B4 B3 B2 B B0 Reserved L Integration Time L Measurement Repeat Rate Field Bits Default Type Description Reserved 7: ms (default) 00 50ms L integration time L measurement rate 5:3 000 RW 2:0 0 RW ms 0 400ms 00 50ms 0 250ms 0 300ms 350ms ms 00 00ms ms 0 500ms (default) ms ms

18 Optical ensor LTR-329L-0 L_DT_H Register (0x88 / 0x89) (Read Only) The L_DT registers should be read as a group, with the lower address read back first (i.e. read 0x88 first, then read 0x89). These two registers should also be read before reading channel-0 data (from registers 0x8, 0x8B). When the I 2 read operation starts, all four L data registers are locked until the I 2 read operation of register 0x8B is completed. This will ensure that the data in the registers is from the same measurement even if an additional integration cycle ends during the read operation. New measurement data is stored into temporary registers and the L_DT registers are updated as soon as there is no on-going I 2 read operation. The L D channel- data is expressed as a 6-bit data spread over two registers. The L_DT_H_0 and L_DT_H_ registers provide the lower and upper byte respectively. 0x88 L_DT_H_0 (default = 0x00) B7 B6 B5 B4 B3 B2 B B0 L Data h Low 0x89 L_DT_H_ (default = 0x00) B7 B6 B5 B4 B3 B2 B B0 L Data h High Field ddress Bits Default Type Description L Data h Low 0x88 7: R L D channel lower byte data L Data h High 0x89 7: R L D channel upper byte data

New data means data has not been read yet. When the measurement is completed and data is written to the data register, the data status bit will be set to logic. When the data register is read, the data status bit will be set to logic 0.
