Automotive Microcontrollers with Emissions Control Technology - MPC5634M, MPC5633M, MPC5632M - Freescale

Freescale  has introduced the MPC563xM a family of 32-bit automotive microcontrollers with integrated emissions control technology. All members of  MPC563xM powertrain microcontrollers (MPC5634M, MPC5633M, MPC5632M) are designed to help reduce emissions of CO2 and provide sophisticated , cost-effective engine control designs. These new 90 nm tech automotive microcontrollers are Freescale’s first automotive products resulting from a joint development program with STMicroelectronics initiated in January 2006.

Target applications of MPC563xM powertrain microcontrollers:

• 1-4-cylinder gasoline direct injection engines
• Low-end diesel engines
• Low-end transmission

The new MPC5634M, MPC5633M, MPC5632M 32-bit powertrain microcontrollers are designed to help improve the performance and efficiency of 1 to 4 four cylinders engines. MPC563xM microcontrollers offer enhanced powertrain functionality, such as on-chip emissions control. The new automotive microcontroller also address the cost constraints of engine and transmission suppliers.

Paul Grimme,  Freescale, said:

The impressive processing power of our MPC563xM microcontrollers enables engine designers to develop powertrain solutions that help reduce CO2 emissions, as well as to address current and future automotive emissions requirements… These advanced, cost-effective microcontrollers are the right products at a time when green automotive technology is critical to addressing the growing concern of global warming…

According to J.D. Power and Associates, the world’s estimated 820 million cars emit on average four tons of CO2 per vehicle each year, totaling about 3.3 billion tons annually. A five percent reduction in all automotive CO2 emissions potentially could remove as much as 165 million tons of CO2 from the atmosphere each year. As a leading greenhouse gas, CO2 is believed to be a major contributor to the greenhouse effect behind global warming. CO2 represents more than 80 percent of greenhouse gas emissions in the United States alone.

The MPC563xM powertrain microcontrollers feature sophisticated emissions control technology that takes advantage of a powerful digital signal processing (DSP) engine built into the Power Architecture e200 core. This integrated DSP capability enables engine designers to maximize fuel economy and performance while minimizing engine knocking,  resulting in a three to five percent reduction in CO2 emissions. Based on single-input/multiple-data (SIMD) processing techniques, the DSP functionality also can be used for patented sensor diagnostics schemes that address on-board automotive diagnostics.

Go Green by Reducing Knock:

• On-chip knock system making tight emissions controls affordable and bringing a 3 to 5 percent improvement of economy and power
• Power and memory size which fast development of “clean sheet” solutions to meet emissions legislation
• No active external components required for on-chip knock system because of variable on-chip gain and sensor bias
• Same integrated components can be used for a patented sensor diagnostics scheme that meets on-board diagnostics

The MPC563xM microcontroller family’s cost-effective pricing helps make advanced emissions control technology more affordable. Cost-sensitive engine designs of up to four cylinders are prevalent in emerging automotive markets such as China and India, where government regulations are moving in a direction of requiring automakers to manufacture more efficient engines that emit fewer harmful emissions.

For automotive developers currently using 16-bit microcontroller solutions for powertrain control, the MPC563xM family provides a cost-effective 32-bit solution that extends processing performance beyond 16-bit capabilities. Offering up to 1.5 MB of flash memory, 81 KB of SRAM, and a Power Architecture core that scales up to 80 MHz, the MPC563xM offers exceptional price and performance for powertrain management applications.

The MPC563xM is Freescale’s first powertrain device family with a quad flat package (QFP) option, offering simplified and lower cost development. A QFP has visible pins, making the package easy and affordable to install, inspect and repair, without requiring costly infrared and X-ray inspection technology. In addition, the MPC563xM devices are software compatible with Freescale’s existing MPC55xx family, which enables code sharing that can help reduce automakers’ development costs.

The MPC563xM product family was developed collaboratively by Freescale and STMicroelectronics. As a result, an architecturally identical dual-sourced product is also available from STMicroelectronics. This unprecedented dual source arrangement is designed to help automotive customers mitigate risk in their supply chain.

The MPC563xM family leverages a comprehensive suite of hardware and software development tools available for the MPC55xx family and Power Architecture technology. Access to this mature ecosystem reduces application development complexity and debugging/validation time during prototyping and software integration phases.

Samples of MPC5634M, MPC5633M, MPC5632M Automotive Microcontrollers are planned to be available to lead automotive customers in this year.
