AVR® DA Product Family The AVR® DA family of microcontrollers feature the well-known AVR® CPU, now running at up to 24 MHz across the full supply voltage range of 1.8V to 5.5V. The family includes 32 KB, 64 KB, and 128 KB Flash variants in 28- to 64-pin package options. The AVR® DA family is designed to bring capacitive touch sensing and real-time control functions to applications including industrial control, home appliance products, automotive, and Internet of Things (IoT).
The family uses the latest Core Independent Peripherals with low-power features and 5V operation for increased noise immunity. The Event System, Configurable Custom Logic (CCL), along with intelligent analog peripherals like 12-bit differential ADC, Zero-Cross Detect (ZCD), DAC, and the latest generation Peripheral Touch Controller (PTC) with driven shield technology make the AVR® DA family perfect for low-latency control applications and capacitive touch user interfaces. The high memory density of the AVR® DA family is well suited for communications stack-intensive applications, both wired and wireless.
AVR32DA28 The AVR32DA28 microcontroller is part of the AVR® DA family featuring the AVR® processor with hardware multiplier, running at up to 24 MHz and with 32 KB Flash, 4 KB SRAM and 512 bytes of EEPROM in 28-pin packages. The AVR32DA28 will be available in SSOP and SOIC package options.
The AVR32DA28 product supports as many as 18 self-capacitance and 81 mutual capacitance touch channels, which makes the AVR® DA the perfect choice for human interface applications where multiple capacitive touch keys, sliders, wheels, or 2D surface are required.
Functional Safety: This product is recommended for safety-critical applications targeting industrial and automotive products (IEC 61508 and ISO 26262). Necessary documentation, such as the FMEDA report and a Safety Manual, can be provided on request. Certified development tools are also available for this product. Contact your local Microchip sales office or your distributor for more information.
