Automotive 8-Bit Microcontrollers

Microchip Technology Automotive 8-Bit Microcontrollers include MCUs with the PIC® and AVR® architecture. Capturing the best features of both architectures enables Microchip to offer plentiful solutions for every type of automotive system. From Human Machine Interface (HMI) applications based on touch technology to underhood applications requiring high-temperature robustness to simple watchdog-type applications requiring a small form factor, users can find extensive options that meet specific requirements.

Functional Safety Solutions

Microchip Technology Functional Safety Solutions offer robustness, reliability, and safety to end-products. In some application segments, these requirements are formalized and mandatory, while in others, they are implemented to differentiate the product and take the step from a good product to an excellent product. The standards for functional safety depend on the market that is targeted. Many standards support multiple levels of rigorousness, which are applied depending on the likelihood and severity of the hazard. The methods of addressing hazards range from detecting single failures and putting the system into a safe state to full redundancy, where failures should not only be detected but also corrected without any interruption or degradation of service.

ATmega328 8-Bit AVR MCUs

Microchip Technology ATmega328 8-Bit AVR MCUs are low-power, CMOS 8-bit microcontrollers based on the AVR® enhanced RISC architecture. The devices execute instructions in a single clock cycle to achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz. This allows for optimizing power consumption versus processing speed.
