How PEPS technology is opening the doors to the evolution of car access systems

Car access has become more convenient as design engineers take advantage of technologies that are widely used in other applications. The automotive industry has evolved from providing mechanical keys to unlock vehicles to fobs with buttons that can unlock vehicles. Now, the most common form of car access revolves around passive entry passive start (PEPS) systems, enabling drivers to enter their car but also start the engine without physically using a key.

Ti:Car access Bluetooth® low energy + CAN satellite module reference design

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

Ti:Adding CAN nodes in Bluetooth® Low Energy PEPS systems

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.

Renesas Extends Bluetooth 5.0 Connectivity to RA Family of 32-Bit MCUs with Arm Cortex-M Core

Enhanced Security and Privacy for Bluetooth 5.0 Low Energy Connections Supported with Flexible Software Package and Comprehensive Arm Ecosystem.

Renesas Electronics Corporation  introduced the first RA microcontroller (MCU) with an integrated Bluetooth® 5.0 Low Energy radio on 07 May 2020. The single-chip RA4W1 MCU includes a 48 MHz, 32-bit Arm® Cortex®-M4 core and Bluetooth 5.0 core delivered in a 56-pin QFN package. Together, the RA4W1 MCU and easy-to-use Flexible Software Package (FSP) enables engineers to immediately begin development with Arm ecosystem software and hardware building blocks that work out-of-the-box with RA MCUs.

The RA4W1 MCU makes it easy for embedded designers to develop safe and secure IoT endpoint devices for Industry 4.0, building automation, metering, healthcare, consumer wearable, and home appliance applications. The MCU is also ideal for developing IoT edge devices for wireless sensor networks, IoT hubs, an add-on to gateways, and an aggregator to IoT cloud applications.
