Flexible and Low-Power: The ATtiny1614 Microcontroller

SOIC-14 Package

The ATtiny1614 is a microcontroller that has been designed to help people bring their ideas to life. It’s a member of the tinyAVR 1-series and packs a punch with its advanced features and capabilities. With a clock speed of up to 20 MHz, 16 KB of Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM, this little chip is perfect for projects that require a lot of processing power in a small package.

The Datasheet for the ATtiny1614 can be found from the Digikey website.

One of the biggest advantages of the ATtiny1614 is its flexibility. It has a range of peripheral options that make it easy to add different types of devices, sensors, and other inputs to your design. This controller comes with I2C, SPI, two ADC channels, a Real Time Counter, a bunch of other features. When you account that it has an internal 16/20 MHz low-power oscillator, all you need to add this to your design is a single decoupling capacitor on pin 1, allowing for a low BOM Line Count when compared to some other controllers.

Another advantage of the ATtiny1614 is its low-power architecture. It has three different sleep modes, which allow you to conserve power when your project is not in use. For example, the Idle mode allows all peripherals to run for immediate wake-up, while the Standby mode allows you to configure the operation of selected peripherals. The Power-Down mode provides full data retention while using the least amount of power.

Loading firmware on the ATtiny1614 is a piece of cake. It uses the UPDI Interface. The Unified Program and Debug Interface (UPDI) is a Microchip proprietary connection for programming and debugging this series of chips. It only uses a single pin to do this. The controller will need to be powered on and it should share a ground with the UPDI programming tool.

If you’re looking to add touch capabilities to your project, the ATtiny1614 has you covered. It has an integrated QTouch Peripheral Touch Controller (PTC) that can handle capacitive touch buttons, sliders, and other 2D surfaces. Best of all, it can wake up your project when it’s touched, so you don’t have to sacrifice power for touch sensitivity.

The ATtiny1614 is a powerful and flexible microcontroller that is perfect for new products that need a brain, but need to conserve power. With its advanced features and low-power architecture, it’s easy to bring your ideas to life and add a range of inputs and outputs. If you’re looking for a chip that can handle complex interactions and help you conserve power, the ATtiny1614 is definitely worth checking out.

This chip is readily available at Digikey and Mouser.
