Next-gen MCUs enable real-time control, connectivity, and HMI apps
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.
The new AVR DA family of MCUs enable CPU speeds of 24 MHz over the full supply voltage range, memory density of up to 128 KB flash, 16 KB SRAM and 512 bytes of EEPROM, 12-bit differential ADC, 10-bit DAC, analog comparators and zero cross detectors. The PTC enables capacitive touch interface designs supporting buttons, sliders, wheels, touchpads, smaller touch screens as well as gesture controls used in a wide range of consumer and industrial products and vehicles.
The AVR DA family of MCUs is supporting up to 46 self-capacitance and 529 mutual capacitive touch channels and features the latest generation PTC with Driven Shield+ and boost mode technologies providing enhanced noise immunity, water tolerance, touch sensitivity and response time. An integrated event system enables inter-peripheral communication without involving the CPU.
Events are latency free and never lost, providing enhanced real-time performance and predictability for reliable and safe designs. By reducing the time the CPU needs be active, the overall power consumption of the application is reduced.
