Automotive-MCU Family Offers Simple Migration

Freescale has developed the S12XS family of 16-bit MCUs for automotive body electronics applications.

The S12XS family includes three devices and provides a compatible extension to the S12XE family, creating a flexible portfolio by offering complementary memory, peripherals and packages. This provides the flexibility to react quickly to market opportunities and reduce the cost of migration if application requirements change.

The full range of S12 and S12X products enables scalability, hardware and software reusability, and compatibility across a broad array of automotive electronics platforms. Compact packaging makes these devices suitable for space-constrained applications, such as small actuators, sensor modules and column-integrated modules.

Freescale’s S12 MCU family is widely adopted in the automotive market, 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 migration path to higher-performance S12X devices.

 

FEATURES 40MHz bus speed 64kB, 128kB and 256kB Flash memory options, all with Error Correction Code (ECC) 4kB to 8kB DataFlash with ECC, used for data or programme storage Choice of configurable 8-,10- or 12-bit ADC, capable of 3µs conversion time Support for Control Area Network (CAN), Local Interconnect Network (LIN) and Serial Peripheral Interface (SPI) protocols 8-channel timer with 16-bit counters Extensive support tools from S12X family

APPLICATIONS Seat controllers Steering-wheel controllers Heat ventilation and air conditioning Sunroofs Door-zone modules Lighting modules ABS and EPS
