The ATtiny1617 is part of Microchip’s low-power, 8-bit AVR® microcontroller portfolio and offers pin and code compatibility with the ATtiny817 series devices, in addition to extended flash memory. The 8-bit series runs at up to 20 megahertz and provides customized configuration and simplified process for capacitive touch systems and core independent peripherals (CIPs) that help increase system throughput while lowering power consumption.

The Microchip ATtiny1617 8-bit AVR microcontrollers feature 16 kilobytes of in-system self-programmable flash memory, 256 bytes of EEPROM and 2 kilobytes of SRAM. These devices are similar to other Microchip tinyAVR® microcontrollers. They use the 8-bit AVR processor with hardware multiplier and provide an event system controller that allows peripherals to communicate without using the central processing unit (CPU). This functionality allows designers to customize the configuration of the microcontrollers to specific applications. Included on the chip is an integrated QTouch® Peripheral Touch Controller (PTC) that helps to simplify the development of capacitive touch systems offering touch interfaced with proximity sensing and a driven shield.

Other features of the microcontroller include a 20 megahertz internal oscillator; high-speed serial communication interface that includes a universal synchronous/asynchronous receiver/transmitter (USART), a serial peripheral interface (SPI) and an inter-integrated circuit (I²C); configurable custom logic blocks; a 10-bit analog-to-digital converter (ADC) with internal voltage reference; operating voltages ranging from 1.8 to 5.5 volts; and picoPower® technology for sleep currents as low at 100 nanoamps.

Microchip’s ATtiny1617 series microcontrollers combine processing power, analog performance and system level integration. They are available in a compact 24-pin quad-flat no-leads (QFN) package. They are also suitable for a variety of power applications, including LED lighting, motor control, H bridges and power converters. For development, the devices are fully supported by the Atmel Studio 7 IDE, the STK600 platform and Atmel’s START online configuration tool.
