A wearable fitness monitor solution example using the PSoC 4 BLE chip is shown on this slide. In this particular solution the PSoC added BLE connectivity to a sensor hub, interfaced with multiple analog and digital sensors, drives a PWM-based vibration motor, and accomplishes this all with low power consumption because this product runs on a coin-cell battery. PSoC 4 BLE enables this with a simple one-chip implementation for BLE connectivity. Using the analog front end the designer can create sensor interfaces for sensors such as temperature, humidity, pressure, and battery voltage. This example implements a custom AFE using the programmable analog blocks, the IDAC can act as a current source, plus the flexible analog MUX all of these being input to the SAR ADC. It can also interface with additional sensors like an accelerometer using the digital SCB, drive a vibration motor using a PWM component, and communicate with a Bluetooth Smart Ready host using the BLE subsystem. It can be seen that a single chip integrates the MCU, the AFE, the digital logic, and the BLE radio all in a simple and very easy-to-use solution.
