8-bit AVR MCUs Offer 16kB Flash


Microchip has added three new devices to the 8-bit tinyAVR MCU family. Called the ATtiny1617 series, the MCUs are claimed to increase system throughput while lowering overall power consumption in embedded applications.

The new MCUs offer 16 KB Flash, 256 B EEPROM, and 2 KB RAM in 14-, 20-, and 24-pin packages.

As mentioned in the Press release, the devices contain key features of other tinyAVR MCUs including the Event System Controller, which allows peripherals to communicate without using the Central Processing Unit (CPU) and enables designers to customize the configuration of the MCU for their specific application.

The new MCUs incorporate an on-chip Peripheral Touch Controller (PTC) to simplify 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 claiming to achieve sleep currents as low as 100 nA.


“There is more growth and innovation in the AVR MCU portfolio now than at any point in the past decade,” said Steve Drehobl, vice president of Microchip’s 8-bit MCU division. “Microchip is committed to continue the AVR MCU family of products.”

The new devices are fully supported by the Atmel Studio 7 Integrated Development Environment (IDE), the STK600 platform and Atmel START, a free online tool to configure peripherals and software for easy development.

The three new tinyAVR MCUs are available today for sampling and in volume production. The ATtiny1617 is available in a QFN24 package starting at $0.68 for 10k units. The ATtiny1616 is available in a QFN20 and SOIC20 package starting at $0.67 and $0.55 respectively for 10k units.The ATtiny1614 is available in a SOIC14 package starting at $0.52 for 10k units.
