That many ADC channels, combined with the 12-bit resolution, means a multi-sensor board (thermistors, potentiometers, current shunts) can skip an external multiplexer or a separate ADC IC. The DAC can generate an analog setpoint or a bias voltage, saving a PWM-plus-filter stage. ## Connectivity and peripherals for industrial and LIN-bus nodes IrDA and RS-485 support are also listed, though those typically need an external transceiver.","metaTitle":"Microchip AVR32DD28T-I/SS 8-bit MCU, 24 MHz, 32 KB Flash","metaDescription":"Microchip AVR32DD28T-I/SS 8-bit AVR MCU: 24 MHz core, 32 KB Flash, 4 KB RAM, 256 B EEPROM, 19x12b ADC, 10b DAC.

It runs at 20 MHz (versus 24 MHz), has 12 I/Os instead of 22, and carries a 9-channel 12-bit ADC versus the 19-channel ADC here. The AVR32DD28T-I/SS offers more I/O, higher ADC channel count, and a DAC — so it fits designs that need those extra analog and GPIO resources."},{"question":"Can AVR32DD28T-I/SS be used with Arduino IDE?","answer":"The AVR® DD series is supported in Microchip Studio and the MPLAB X IDE ecosystem. Arduino IDE support depends on third-party board packages; as of the current release cycle, the AVR DD family is not natively listed in the official Arduino board manager.
