Microchip’s AVR DA family of microcontrollers is recommended for safety-critical applications in both industrial and automotive products. In addition to being functional safety-ready, the series offers a peripheral touch controller (PTC) and peripheral event system for enhanced real-time control and HMI performance and predictability.

AVR DA microcontrollers integrate several safety functions to ensure robust operation and sufficient supply voltage, such as power-on reset, brown-out detection, and voltage-level monitoring. A cyclic redundancy check (CRC) scan of application code in flash memory maintains code integrity, circumventing unintended and potentially unsafe behavior of the application.

The integrated PTC enables capacitive touch interface designs supporting buttons, sliders, wheels, touchpads, smaller touch screens, and gesture controls used in a wide range of consumer and industrial products and vehicles. Inter-peripheral communication without CPU involvement is made possible by the microcontroller’s integrated event system. Events are latency-free and never lost.

Other features include CPU speeds of 24 MHz over the full supply voltage range, up to 128 kbytes of flash memory, 16 kbytes of SRAM, 512 kbytes of EEPROM, 12-bit differential ADC, 10-bit DAC, analog comparators, and zero cross detectors. A configurable custom logic peripheral allows the setup of logic functions internally, eliminating external components and reducing board space and BOM costs.

Prices for the AVR DA series of microcontrollers start at $0.87 each in lots of 10,000 units.
