Broadcom APDS-9253-001-DS102 APDS-9253-001 Data Sheet Digital RGB Sensor Principles of Operation System State Machine Start Up after Power-On or Software Reset The main state machine is set to Start State during power-on or software reset. As soon as the reset is released, the internal oscillator is started and the programmed I2C address and the trim values are read from the internal non-volatile memory (NVM) trimming data block. The device enters Standby Mode as soon as the Idle State is reached. 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 is selected with the respective bit in the MAIN_CTRL register), the internal support blocks are immediately powered on. Once the voltages and currents are settled (typical after 500 μs), the state machine checks for trigger events from a measurement scheduler to start conversions according to the selected measurement repeat rates. When the user resets the LS_EN bit to 0, a running conversion is completed and the relevant ADCs move to Standby Mode thereafter. The support blocks only move to Standby Mode if all sensors are Inactive. If any of the sensors is programmed to sleep after interrupt with the according bit in the MAIN_CTRL register, the relevant ADCs move to Standby Mode after the interrupt condition occurred. Also the sensor's Enable bit LS_EN is reset after following read out of Main Status register. The deactivation LS in the MAIN_CTRL register does not clear the related status bit in the MAIN_STATUS register. They are always reset upon activation of the respective sensor.

Broadcom APDS-9253-001-DS102 APDS-9253-001 Data Sheet Digital RGB Sensor Light Sensor Operation APDS-9253-001 can be configured to run in ALS mode or in RGB mode. The difference between both submodes of the light sensor (LS) is in the activation of the sensor channels. ALS mode is offered for power saving if the full RGB functionality is not needed. Light Sensor Interrupt The interrupt is configured by the bit in the INT_CFG register. It can function as either threshold triggered (LS_VAR_MODE = 0) or variance trigged (LS_VAR_MODE = 1). The threshold interrupt is enabled with LS_INT_EN = 1 and LS_VAR_MODE = 0. The interrupt is set when the respective LS_DATA register 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 for a specified number of consecutive measurements as configured in the INT_PST register (1+LS_PERSIST). The variance 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 for a specified number of consecutive measurements (1+LS_PERSIST). For LS, an interrupt can also be triggered if the output variation of consecutive conversions has exceeded a defined limit. I2C Protocol Interface and control of the APDS-9253-001 is accomplished through an I2C serial compatible interface (standard or fast mode) to a set of registers that provide access to device control functions and output data. The device supports a single slave address of 0x52 hex using 7-bit addressing protocol. (Contact factory for other addressing options.) I2C Register Read The registers can be read individually 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 read, the address counter in the device does not roll over and the device returns 00HEX 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 ALS result registers, the result update is blocked. If a read access is started on an address belonging to a non-readable register, the APDS-9253-001 returns NACK until the I2C operation is ended.

Broadcom APDS-9253-001-DS102 APDS-9253-001 Data Sheet Digital RGB Sensor Read operations must follow this timing diagram. I2C Register Write The APDS-9253-001 registers can be written to individually or in block write mode. When two or more bytes are written in block write mode, reserved registers and read-only registers are skipped. The transmitted data is automatically applied to the next writable register. If a register includes read (R) and read/write (RW) bit, the register is not skipped. Data written to read-only bit is ignored. If the last valid address of the APDS-9253-001 address range is reached but the master attempts to continue the block write operation, the address counter of the APDS-9253-001 does not roll over. The APDS-9253-001 returns NACK for every following byte sent by the master until the I2C operation is ended. If a write access is started on an address belonging to a non-writeable register, the APDS-9253-001 returns NACK until the I2C operation is ended. Write operations must follow this timing.

Broadcom APDS-9253-001-DS102 APDS-9253-001 Data Sheet Digital RGB Sensor Application Information: Hardware The application hardware circuit for implementing APDS-9253-001 is shown in following figure. The bypass capacitor is placed as close to the device package as possible and is connected directly to the power source and to the ground, as shown in the following figure. It allows the AC component of the VDD to pass through to ground. It is suggested that you use a bypass capacitor that has a low effective series resistance (ESR) and low effective series inductance (ESI), such as the common ceramic types, which provide a low impedance path to ground at high frequencies to handle transient currents caused by internal logic switching. Pull-up resistors, RSDA and RSCL, maintain the SDA and SCL lines at a high level when the bus is free and ensure the signals are pulled up from a low to a high level within the required rise time. A pull-up resistor, RINT, is also required for the interrupt (INT), which functions as a wired-AND signal, similar to the SCL and SDA lines. A typical impedance value of 10 kΩ can be used.

Broadcom APDS-9253-001-DS102 APDS-9253-001 Data Sheet Digital RGB Sensor Recommended Reflow Profile The reflow profile is a straight-line representation of a nominal temperature profile for a convective reflow solder process. The temperature profile is divided into four process zones, each with different ΔT/Δtime temperature change rates or duration. The ΔT/Δtime rates or duration are detailed in the previous table. The temperatures are measured at the component to printed circuit board connections. In process zone P1, the PC board and component pins are heated to a temperature of 150°C to activate the flux in the solder paste. The temperature ramp up rate, R1, is limited to 3°C per second to allow for even heating of both the PC board and component pins. Process zone P2 should be of sufficient time duration (100s to 180s) to dry the solder paste. The temperature is raised to a level just below the liquidus point of the solder. Process zone P3 is the solder reflow zone. In zone P3, the temperature is quickly raised above the liquidus point of solder to 260°C (500°F) for optimum results. The dwell time above the liquidus point of solder should be between 60s and 120s. This is to ensure proper coalescing of the solder paste into liquid solder and the formation of good solder connections. Beyond the recommended dwell time, the intermetallic growth within the solder connections becomes excessive, resulting in the formation of weak and unreliable connections. The temperature is then rapidly reduced to a point below the solidus temperature of the solder to allow the solder within the connections to freeze solid. Process zone P4 is the cool down after solder freeze. The cool down rate, R5, from the liquidus point of the solder to 25°C (77°F) should not exceed 6°C per second maximum. This limitation is necessary to allow the PC board and component pins to change dimensions evenly, putting minimal stresses on the component. It is recommended to perform reflow soldering no more than twice.
