Two recent announcements by Freescale ensure the reality of an IoT car and a safer vehicle through tire-pressure sensing. Freescale's comprehensive hardware/software development system provides automotive grade Ethernet connectivity for infotainment, instrument cluster, camera telematics, and rear-seat entertainment. The system provides for real-time data transport throughout vehicles, doing away with expensive digital technologies.
The SABRE (Smart Application Blueprint for Rapid Engineering) for Auto Infotainment (AI) development system leverages Freescale's i.MX 6 series applications processors, simplifying Ethernet Audio Video Bridging (AVB) deployment and connecting a broad array of onboard multimedia nodes using automotive grade Ethernet components. Now cars, drivers, the cloud, and the IoT are joined.
Freescale's corresponding Microcontroller Software Solutions supports the development of Ethernet AVB connectivity applications for automotive. SABRE AI supports both 100Mbit/s automotive Ethernet physical interfaces as well as multi-port switches to allow customers to design for their specific needs.
The solution features:
- SABRE Automotive Rev2 CPU Cards with i.MX 6Quad and i.MX 6DualLite applications processors (MCIMX6QAICPU2, MCIMX6DLAICPU2)
- New "Flexible Ethernet Expansion" header supporting:
- Atheros Gb PHY (software compatible with CPU1 systems)
- 10/100 Broadcom® BroadR-Reach® PHY
- 10/100 Broadcom BroadR-Reach 4-port switch
Freescale's newest SABRE (Smart Application Blueprint for Rapid Engineering Engineering) for Auto Infotainment (AI) is sampling now, with broad availability expected in the first quarter of 2015.
The second announcement involves the integration of tire pressure monitoring into a small package featuring extremely low power consumption through precise tire pressure sensing. The FXTH87 tire pressure monitoring system (TPMS) family weighs in at only 0.3 grams and is 50% smaller than competing products.
The TPMS system-in-package solution features a dual-axis accelerometer architecture, pressure and temperature sensor, integrated MCU, RF transmitter, and low-frequency receiver.
According to the NTSB, 23,000 accidents and 535 vehicle fatalities occur annually that involve flat tires or blowouts. That's one thing when a person is behind the wheel and in control. However, as automotive control moves to the vehicle itself, tire pressure monitoring and safety becomes even more critical. According to IHS iSuppli, TPMS will represent more than 25% of the total pressure measurement market for automotive sensors by 2015.
