Freescale Introduces 16-Bit Microcontroller for Automotive Electronics

Addressing customer needs for design flexibility and platform compatibility, Freescale Semiconductor (NYSE:FSL) (NYSE:FSL.B) has unveiled a 16-bit microcontroller (MCU) family optimized for a broad range of cost-sensitive automotive body electronics applications. The family includes six devices designed to give customers flexibility in choosing different memory, package and cost options to accommodate their application requirements.

The latest addition to the S12X portfolio, the S12XS family provides an economical, compatible extension to the recently announced high-performance S12XE family. It also broadens the overall S12X product offering and provides customers with lower cost and smaller package options. The S12XS and S12XE families have complementary memory, peripherals and packages. This flexibility can help designers react quickly to market opportunities and reduce the cost of migration if application requirements change during the development cycle. The full range of S12 and S12X products enables scalability, hardware and software reusability, and compatibility across a broad array of automotive electronics platforms.

The S12XS family features a streamlined set of on-chip peripheral, memory and package options optimized for automotive body and passenger comfort applications. Potential applications include seat controllers, heat ventilation and air conditioning (HVAC) control modules, steering wheel controllers and sunroofs. The S12XS devices are also available in QFN packages as small as 7mm x 7mm – a reduced size for a 16-bit MCU. Compact packaging makes these devices suitable for space-constrained applications, such as small actuators, sensor modules and column-integrated modules.

“Automotive electronics customers continually look for ways to reduce development cost and time while maintaining software and hardware reusability across applications and platforms,” said Mike McCourt, vice president and general manager of Freescale’s microcontroller division. “With the introduction of the S12XS family, Freescale now offers a full range of compatible, 16-bit price/performance options, giving customers greater flexibility in their body electronics designs.”

Freescale offers a broad range of price, performance, peripheral and package options within each of its MCU families and provides automotive customers with choices that span 8-, 16- and 32-bit architectures. Within each product family and architecture, customers can choose the optimal device at the right price point for their application needs and easily migrate to higher performance and more advanced functionality. They also can leverage common sets of hardware and software tools, which can help reduce development cost and speed time to market.

Freescale’s S12 MCU family is the most widely adopted 16-bit architecture in the automotive market. S12-based devices are now shipping at a rate of more than 100 million units per year. The scalable S12 family offers developers a range of choices for their application needs, with on-chip flash scaling from 32KB to 1MB and a smooth migration path to higher performance S12X devices.
