AVR DA Functional Stability Certified MCU,
Built-in independent capacitive touch controller


A family of high-performance MCUs for HMI (Human-Machine Interface) has been released.

On the 6th, Microchip Technology unveiled a family of next-generation AVR® DA Functional Safety Ready MCUs with an embedded Peripheral Touch Controller (PTC).

The built-in PTC is designed independently of the CPU, and with the application of Driven Shield+ and Boost Mode technologies, a highly responsive capacitive touch design is possible. In addition, it supports up to 46 self-capacitance sensors and up to 529 mutual capacitance sensors.

The AVR DA MCU family includes integrated safety functions such as POR (Power-on Reset), BOD (Brown-Out Detect), VLM (Voltage Level Monitor), and CRC (Cyclic Redundancy Check).

It provides a CPU speed of 24 MHz in the maximum supply voltage range, a flash memory density of up to 128 KB, 16 KB SPRAM and 512 byte EEPROM, a 12-bit differential ADC, a 10-bit DAC, an analog comparator (AC), and a zero-cross detector.

Microchip provides software and hardware support for engineers who wish to use the AVR DA MCU family.

Software provided includes code configuration tools such as MPLAB® X, MPLAB Xpress, Atmel Studio, MCC, and START, and compilers such as GCC, XC8, and IAR Embedded Workbench. A functionally stable certified version of the XC8 compiler is provided through Microchip’s functional stability compliance program.

Hardware includes a debugger/programmer with MPLAB PICkit™ 4, MPLAB SNAP, Atmel ICE, and the AVR128DA48 Curiosity Nano evaluation kit.

The AVR DA MCU family can be mass-produced in units of 10,000 and starts at $0.87.
