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.

ATmega644PA 8-bit AVR® Microcontrollers

Microchip ATmega644PA 8-bit AVR^® CMOS Microcontrollers are low-power and based on the AVR^® enhanced RISC architecture. The Atmel ATmega644PA is a powerful 8-bit microcontroller, that offers excellent flexibility and a cost-effective solution to a wide range of embedded control applications.

megaAVR® CMOS 8-bit Microcontrollers

Microchip Technology megaAVR^® CMOS 8-bit Microcontrollers are low-power microcontrollers that are based on the AVR^® enhanced RISC architecture. The devices like ATmega164A, ATmega164PA, ATmega324A, ATmega324PA, ATmega644A, ATmega644PA, ATmega1284, and ATmega1284P fall under the megaAVR category of microcontrollers. These devices feature 16KB to 128KB FLASH memory, 1KB to 16KB SRAM, and 512bytes to 4KB EEPROM. The megaAVR devices execute instructions in a single clock cycle that helps the CPU to achieve a throughput of one Million Instructions Per Second (MIPS) per megahertz. This allows the system designer to optimize power consumption versus processing speed.
