The GW7125 is a device that combines an integrated microcontroller and an analog front end to provide ultrasonic range detection using a minimal number of components. Its pulse-width modulation (PWM) output allows for programmable bursts to be sent to a single ultrasonic transducer. With the support of compatible transducers, this device allows for distance measurement ranging from 10cm to 6m using an external Transformer, from 10cm to 4.5m using a Tri-State-buffer and can be utilized for presence detection within the range of 0cm to 10cm.
By utilizing internal components such as a programmable gain amplifier (PGA), a 12-bit analog-to-digital converter (ADC), digital filters, an envelope detector, and a peak detector, the desired measurement range and resolution can be achieved. Additionally, the device includes an internal temperature sensor and ADC for reading operating temperature information.
The device includes a 16KB embedded Flash memory for storing application-specific program and data, while a 2KB SRAM is available for storing data required for signal processing purposes.
The GW7125 offers various communication interfaces, including UART, I2C and I/O communication making it convenient to connect with a host device.
