Freescale, Infineon, and STMicroelectronics made major chip announcements this week all focused on improving fuel economy and reducing emissions.
Freescale said its multicore Qorivva 32-bit MPC5676R MCU, built on Power Architecture® technology, provides four times the performance, double the memory space and more functionality than the previous-generation, single-core MPC5566 MCU. With two parallel 180 MHz, 32-bit Power Architecture processors, the chip will allow automakers to incorporate technology such as direct injection, turbo-charging and full drive-by-wire systems into a single controller.
Infineon described its 32-bit MCU multicore architecture as the foundation of Infineon’s next-generation MCU family for upcoming automotive powertrain and safety applications. The architecture features up to three TriCore™ processor cores connected over a crossbar running at the full CPU speed and avoiding hardware contentions. It implements multiple program Flash modules with independent read interfaces that further support real-time capability, and it contains enhanced hardware safety mechanisms.
STMicro said its L99PM72PXP, developed with a German car maker, is among the first ICs in the market to support partial networking. The chip, part of STMicro’s automotive CAN/LIN transceiver portfolio, should help car makers respond to legislation in major markets worldwide aiming to save fuel and reduce emissions. Partial networking is a new feature in the latest CAN specification, ISO 11898-6, and could reduce an average vehicle’s CO2 emission by more than 2g/km.
In Europe, Euro 6 regulations will replace Euro 5 in 2014, and the average CO2 emissions limit will fall to 95g/km by 2020. Chinese 4 standards, similar to Euro 4, came into force in China in 2011 and the city of Beijing is planning to adopt Chinese 5. In the USA, Corporate Average Fuel Economy (CAFE) requirements for passenger cars will increase from 30.4 to 37.8 mpg by 2016 and 50.6 mpg by 2025.
