BH1680FVC-TR

BH1680FVC-TR is ROHM’s digital ambient light sensor. The “-TR” suffix denotes Tape & Reel packaging for high‑volume manufacturing. The device integrates photodiodes and on‑chip signal processing to deliver digital illuminance data via I2C, making it ideal for automatic brightness control and light monitoring in displays and mobile devices.
Key points:
- Interface: I2C (digital output)
- Packaging: Tape & Reel (TR) for automated assembly
- Applications: display backlight control, smartphones/tablets, notebooks, automotive panels, smart sensors
- Features (typical): small footprint, low power, integrated ADC, suitable dynamic range; may offer configurable integration time/gain depending on variant
- Use: power, connect SDA/SCL, read lux data from data registers per datasheet; implement smoothing/hysteresis in the host MCU
For exact electrical specs, register map, and programming details, refer to the BH1680FVC datasheet.

Possible equivalents (I2C RGB color sensors):
- TCS34725/TCS34727 (AMS) – RGB+Clear with IR-cut filter; built-in ADC; I2C.
- APDS-9960 (Broadcom) – RGB color sensor with proximity; I2C.
- ISL29125/ISL29122 (Renesas/Intersil) – 16-bit color sensor; I2C.
Note: spectral response, integration time, and packaging differ; verify datasheets and packaging (TR = tape-and-reel) for exact compatibility.

- Pin count: 8 pins (BH1680FVC-TR in an 8-pin package).
- Function: Digital ambient light sensor with a light-to-digital converter and I2C interface. Provides lux data; includes an I2C address select pin and an interrupt output. TR denotes Tape & Reel packaging.

Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.).
What kind of company: A Japanese multinational semiconductor company that designs and manufactures integrated circuits and electronic components (ICs, sensors, diodes, transistors, LEDs) for automotive, consumer, and industrial markets.
