Microchip ATtiny1617 series of AVR microcontrollers

The ATtiny1617 microcontroller series is part of Microchip Technology’s low-power 8-bit AVR microcontroller portfolio. The compact device runs at up to 20 MHz and provides a customised configuration and simplified process for capacitive touch systems, plus Core Independent Peripherals (CIPs) that help increase system throughput while lowering overall power consumption.

The AVR microcontroller features 16 KB of in-system self-programmable flash memory, 256 B of EEPROM and 2 KB of SRAM. It uses the 8-bit AVR processor with a hardware multiplier and provides an event system controller that allows peripherals to communicate without using the CPU. This enables designers to customise the configuration of the microcontroller to specific applications. Also included on-chip is an integrated QTouch Peripheral Touch Controller (PTC) that helps to simplify the development of capacitive touch systems, offering touch interfaces with proximity sensing and a driven shield.

Other integrated features include a 20 MHz internal oscillator; high-speed serial communication interfaces that include USART, SPI and I²C; configurable custom logic blocks; a 10-bit analog-to-digital converter (ADC) with internal voltage references; operating voltages ranging from 1.8 to 5.5 V; and picoPower technology for sleep currents as low as 100 nA. The microcontrollers are available in a 24-pin QFN package and are suitable for a variety of power applications, including LED lighting, motor control, H bridges and power converters.
