The AVR DA Family Incorporates Several New Safety Features Together With Integrated Peripheral Touch Controller
As the Internet of Things (IoT) delivers greater connectivity for industrial and home applications and as connected vehicles enhance cabin and operational features, higher-performance microcontrollers are required for better real-time control as well as to enable enhanced human machine interface applications. Microchip has released its next generation AVR® DA family of microcontrollers (MCUs) – its first Functional Safety Ready AVR MCU family with Peripheral Touch Controller (PTC).
With this AVR DA family of microcontrollers Microchip builds on our legacy of high performance and high code efficiency devices, now meeting new demand across multiple industries with advanced analog and core independent peripherals, and more capacitive touch channels over existing devices, said Greg Robinson, associate vice president of marketing, 8-bit microcontroller business unit. The technology spans applications from connected home security, building automation and sensor systems to automotive and industrial automation, enabling the designs of more robust, accurate and responsive applications.
Microchip’s Functional Safety Ready designation is applied to devices that incorporate the latest safety features and are supported by safety manuals, Failure Modes, Effects, and Diagnostic Analysis (FMEDA) reports, and in some cases, diagnostic software – reducing the time and cost of certifying safety end applications. The AVR DA MCU family includes several integrated safety functions to ensure robust operation – features ensuring a sufficient supply voltage such as power-on reset, brown-out detector and voltage-level monitor. The cyclic redundancy check (CRC) scan ensures the application code in the flash memory is valid. By ensuring code integrity, unintended and potentially unsafe behavior of the application can be avoided.
