New ATtiny MCUs join AVR lineup

22 March 2017 DSP, Micros & Memory

Microchip announced further expansion of its AVR microcontroller (MCU) portfolio with the addition of three new devices to the tinyAVR family. The new ATtiny1617 series of MCUs expands the range of AVR devices that feature core independent peripherals (CIPs), which help to increase system throughput while lowering overall power consumption. The new devices extend the memory offering for these next-generation tinyAVR MCUs with new 16 KB Flash options, while remaining pin- and code-compatible with the recently released ATtiny817 series devices. Furthermore, all members of the family are supported by Atmel START, an online tool for intuitive graphical configuration of embedded software projects.

The new MCUs offer 16 KB Flash, 256 B EEPROM and 2 KB RAM in 14-, 20- and 24-pin packages. The devices contain key features of other tinyAVR MCUs including the event system controller, which allows peripherals to communicate without using the CPU and enables designers to customise the configuration of the MCU for their specific application. The on-chip peripheral touch controller (PTC) simplifies the development of capacitive touch systems. Other integrated features include: a 20 MHz internal oscillator, high-speed serial communication with 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 V to 5,5 V, and picoPower technology for sleep currents as low as 100 nA.

The new devices are fully supported by the Atmel Studio 7 Integrated Development Environment (IDE), the STK600 platform and Atmel START.
