SECO-NCV7685RGB-GEVB NCV7685 RGB Lighting Evaluation Board User s Manuals Description www.onsemi.com SECONCV7685RGBGEVB is an evaluation board for RGB LEDs lighting application with BLE in automotive which driven by EVAL BOARD USERS MANUAL NCV7685 and controlled by RSL10. It is also an interior or exterior lighting reference design for tail or ambient lights to realize general sequential or high end pixelated LEDs controlling invehicle network. The user can set RGB LEDs color and intensity by mobile APP to show customized information or animation. In general, the user prefers to use fixed address in multiple NCV7685 applications. It leads to additional procedure to preprogram each chips address in mass production stage. In addition, it is inconvenient for maintenance in the aftermarket. In firmware of this evaluation board, it uses floating address setting method, each time when power on the board, NCV7685 will be assigned an address which is defined by user, but its not locked into OTP registers. The user can realize this function by using either RSL10s GPIO or IO expender (PAC9655). In firmware, the driver APIs are divided into four levels: Peripheral, Chip, Board and customer application. User can directly include the chips and board APIs in their own project, and modify the application APIs according to their applications. This will accelerate developing period to market. The board conceived for use as a plug and play environment to testing. Nominal supply voltage is 12 V (Supply voltage range 1224 V). In switch mode, four fixed animations shown the RGB LEDs color and intensity setting by user mobile APP in BLE mode. Features Plug and Play Switch and BLE Mode to Show Animations 16 RGB LEDs (48 Channels), each Current Programmable Sources up to 60 mA Independent PWM Duty Cycle Control for each Channel OnChip 150, 300, 600 and 1200 Hz PWM Logarithmic or linear independent PWM dimming Diagnostic and Protection against Open Load and UnderVoltage, Over Temperature Dynamic Addressing Method for NoWorries in mass production Bluetooth 5 Certified with LE 2M PHY Support Rx Sensitivity (Bluetooth Low Energy Mode, 1 Mbps): 94 dBm Transmitting Power: 17 to +6 dBm Arm CortexM3 Processor and LPDSP32 AECQ100 Qualified and PPAP Capable Semiconductor Components Industries, LLC, 2020 1 Publication Order Number: May, 2020 Rev. 1 EVBUM2713/DSECONCV7685RGBGEVB Architecture and Key Parts Figure 1.
