Increase Functionality in Sensor Nodes with New 8-bit tinyAVR® MCUs

Increase Functionality in Sensor Nodes with New 8-bit tinyAVR® MCUs 

ATtiny3217 and ATtiny3216 join Microchip’s tinyAVR family with largest memory in the series

AVR® microcontrollers (MCUs) have long been used to create highly responsive sensor nodes because of their cost effectiveness and ease of implementation. To enhance the capability and responsiveness of applications in these settings, Microchip Technology Inc. (NASDAQ: MCHP) has expanded its tinyAVR MCU series to include two new devices with advanced analog features and the largest memory variant in the family. Designed for reliable operation in harsh environments, the devices come with built-in safety functions to help designers create robust and safe systems.

Ideal for sensor applications including capacitive touch interfaces, the ATtiny3217 and ATtiny3216 bring the benefit of two Analog-to-Digital Converters (ADCs) that enable systems to implement touch control simultaneously with other analog measurements. One ADC can be used with the Peripheral Touch Controller (PTC) for touch signal acquisition, while the second one monitors other inputs such as thermistors and pressure sensors, or both ADCs can be used for faster sampling of different types of sensors. Additional benefits of the ATtiny3217 and ATtiny3216 MCUs include:

  • Improved real-time performance and accuracy: The dual ADC can be used for synchronous sampling of analog signals, such as voltage and current, thus improving the overall system real-time performance and accuracy. Additionally, the devices feature a hardware-based Event System that enables inter-peripheral communication without CPU involvement, reducing latency and ensuring faster system response. 
  • Robust and reliable performance: Both devices come with built-in safety functions to help designers detect and respond to voltage supply variations or drops, including the Power On Reset (POR), programmable Brownout Detect (BOD), Voltage Level Monitor (VLM) and Windowed Watchdog Timer (WWDT).
  • Improved noise immunity and functionality in extreme environments: The devices operate at up to 5V and come available in 125°C variants.
  • Increased functionality with more room for application code: With 32 KB of Flash, designers have plenty of room for their application code while retaining a small physical footprint on the PCB.

“We continue to invest in bringing new AVR MCUs to the market with advanced features that meet our customers’ needs while easing the development process,” said Steve Drehobl, vice president of Microchip’s MCU8 division. “The combination of responsive touch sensing and built-in safety functions make it easier for designers to improve the user experience in applications such as home appliances, automotive and industrial automation.”

The ATtiny3217 and ATtiny3216 are the latest devices in Microchip’s tinyAVR family of MCUs, including the ATtiny1617 and the ATtiny817, which are optimized for performance, power efficiency and ease of use in small packages.

Development Tools

All tinyAVR MCU series devices are supported by the Atmel Studio 7 integrated development environment (IDE) and the Atmel START code configurator. For evaluation purposes, the ATtiny3217 Xplained Pro evaluation kit is also available.

Pricing and Availability

The ATtiny3217 and ATtiny3216 are available now for sampling and in volume production starting at $0.68 each in 10,000-unit quantities. The ATtiny3217 Xplained Pro evaluation kit (ATTINY3217-XPRO) is available now for $38 each.
