32-bit MCUs for Automotive 

Whether designing for automotive touch applications or infotainment, our scalable 32-bit microcontroller (MCU) portfolio can meet a wide variety of automotive needs. Our entry-level devices feature LIN connectivity and a Peripheral Touch Controller (PTC), while the high-performance devices include Ethernet-AVB, CAN FD and Media Local Bus (MediaLB®) connectivity which are ideal for applications such as infotainment as well as smart antennas.


The SAM V70 series of microcontrollers is a high-performance Arm® Cortex®-M7 AEC-Q100 Grade 2-based device which provides a combination of connectivity interfaces including CAN FD, MediaLB and HS USB with up to 300 MHz (1500 CoreMarks) in performance.


The SAM V71 series of microcontrollers extends the SAM V70 series by adding Ethernet-AVB capabilities as well as providing more extensive the memory options. Both the SAM V70 and SAM V71 offer excellent Digital Signal Processor (DSP) processing for audio applications as well as supporting AUTOSAR.


The PIC32MZ EF series offers a wide range of connectivity interfaces with CAN 2.0B, Hi-Speed USB OTG and 10/100 Ethernet as well as high performance analog. The PIC32MZ EF is AEC-Q100 Grade 1 qualified and is ideal for applications like ADAS which need connectivity as well as analog performance. In addition, AUTOSAR is also supported on the PIC32MZ EF family.


The SAM DA1 series of microcontrollers is an entry-level MCU that includes a Peripheral Touch Controller (PTC) which enables efficient capacitive touch measurement on sensors that function as button, sliders and wheels for HMI applications such as door handle sensors or in-cabin touch. The LIN driver is supported from IHR. AEC-Q100 Grade 2 is the current temperature range supported on the SAM DA1.


The SAM D21 series of microcontrollers extends the capability of the SAM DA1 series for both memory as well as temperature. The SAM D21 is AEC-Q100 Grade 1 qualified and extends the memory to 256 KB of Flash. As with the SAM DA1, the LIN driver is supported from IHR.


The SAM C21 series of microcontrollers extends the capability of the SAM D21 series by adding dual CAN FD as well as offering 5V operation for harsh environments. The SAM C21 is AEC-Q100 Grade 1 qualified and offers up to 256 KB of on-board Flash. Stacks for both LIN and CAN are supported by third parties, including IHR and Vector.


The PIC32MM series of microcontrollers provides up to 256 KB of ECC program Flash with small package options. In addition, the PIC32MM offers eXtreme Low Power (XLP) technology and LIN and USB connectivity. The PIC32MM is AEC-Q100 Grade 1 qualified and is ideal for LIN-connected applications for in-cabin or body electronics.
