This reference design enables a wearable, optimized saturation of peripheral capillary oxygen (SpO2) and multi-sensor, multi-wavelength optical heart rate monitor (HRM). It uses AFE4420 device, which is a single-chip, bio-sensing front end for photoplethysmography (PPG) measurements. It supports up to four switching light-emitting diodes (LEDs) and up to four photodiodes to enable signal acquisition of up to 16 Phases. The CC2640R2F device (supporting Bluetooth® low energy 4.2 and 5) transfers the measured data to a remote location. This patient-monitoring design uses a single CR3032 battery with a 30-day life cycle. Raw data is available to calculate heart rate, SpO2, and other related parameters. 2 onboard light-emitting diodes (LEDs) identify low-battery detection and a Bluetooth connection.

This satellite module reference design is intended for Bluetooth® low energy passive entry passive start (PEPS) and phone as a key / digital key car access systems. The design demonstrates how control area network flexible data rate (CAN-FD) communication capabilities can be implemented with our Bluetooth wireless MCUs for systems that require higher bandwidth in-vehicle networking communications. Further benefits include reduced power consumption in the sleep state, our CAN auto-addressing method for improved manufacturing, connection monitor capabilities for improved Bluetooth localization accuracy and a compact printed-circuit board (PCB) capable of measuring Bluetooth angle of arrival (AoA) and received signal strength index (RSSI).

Ti integrated circuits and reference designs help you design passive entry passive start (PEPS) modules and key fobs that are secure and compact while reducing system power consumption and optimizing RF and vehicle 

 

In a passive-entry-passive-start (PEPS) automotive system using Bluetooth® Low Energy technology, drivers enter their car and start the electric motor (or engine, in the case of an internal combustion engine) using a key fob that communicates with the car’s access systems, instead of a key.
