Renesas Synergy™ Platform
4.3 Installed Sensors
The on-board sensors provide variety of options when it comes to prototyping IoT applications:
• Accelerometer, Gyroscope and Magnetometer: Bosch Sensortec - BMI160 (U4) and BMM150 (U9)
BMI160 is an extremely small low power and low noise 6-axis accelerometer and gyroscope.
The integrated accelerometer provides all functionalities of Bosch Sensortec's leading-edge 12-bit digital
accelerometer, including a 32-frame FIFO buffer storing acceleration data.
The interface to the MCU is based on the I
• Accelerometer = 0x68
• Magnetometer = 0x10
Connected to MCU I
• Data (SDA) = P5_11
• Clock (SCL) = P5_12
• Environmental Sensor: Bosch Sensortec. – BME680 (U7)
The BME680 is a digital 4-in 1 sensor with gas, humidity, pressure, and temperature measurement based on
proven sensing principles
The interface to the MCU is based on the I
Connected to MCU I
• Data (SDA) = P5_11
• Clock (SCL) = P5_12
• Ambient Light Sensor: Renesas - ISL29035 (U6)
The ISL29035 is an integrated ambient and infrared light-to-digital converter with I
advanced self-calibrated photodiode array emulates human eye response with excellent IR rejection. The on-chip
16-bit ADC is capable of rejecting 50 Hz and 60 Hz flicker caused by artificial light sources. The Lux range
select feature allows users to program the Lux range for optimized counts/Lux.
The interface to the MCU is based on the I
Connected to MCU I
• Data (SDA) = P5_11
• Clock (SCL) = P5_12
• MEMS Microphone: Knowles SPM0687LR5H-1 (U10)
The SPM0687LR5H-1 is a miniature, high-performance, low power, top port silicon microphone. It consists of
an acoustic sensor, a low noise input buffer, and an output amplifier.
The device has the following main features:
• 20 dB of Gain
• Low current consumption
• MaxRF protection
• Ultra-stable performance
• Omnidirectional
The microphone output is wired to MCU ADC Channel 1 (P0_1).
