32-Bit SAM V Microcontrollers Microchip Technology 32-Bit SAM V Microcontrollers are Arm® Cortex®-M7 based automotive MCUs optimized for in-vehicle infotainment connectivity for audio amplifiers, telematic control units, or head units. The SAM V MCUs provide a wide range of connectivity interfaces, including Ethernet AVB, MediaLB, USB, and CAN-FD. Additional peripherals include an SDRAM controller, external bus interface with a static memory controller, up to 24-channel 12-bit Analog-to-Digital Converter (ADC), up to 2-channel Digital-to-Analog Converter (DAC), three USARTs configurable as SPI, five UARTs, and up to three 2-wire interfaces.
