Enhanced Peripheral Touch Controller Added to New ATtiny Microcontrollers
The PTC features Superior Water Tolerance and can be configured by the START Code Configurator
Microchip has further expanded its AVR® microcontroller (MCU) portfolio by adding three new devices to the tinyAVR® MCU family.
The new ATtiny1617 series of MCUs expand the range of AVR devices that feature Core Independent Peripherals (CIPs),
which help 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.
CIPs are designed to handle their task with no code or supervision from the CPU to maintain operation. As a CIP, the Peripheral Touch Controller simplifies the implementation of touch sensing and thus gives designers the flexibility to focus on the rest of the application.
Touch solutions using the PTC combine advanced noise handling, water-tolerant touch and low-power wake-on-touch operation. An IEC 61000-4-6 conducted immunity rating of 15 Vrms makes it easy for customers to pass the strictest electromagnetic compatibility (EMC) standards, especially in the home appliance and automotive markets. Water-tolerant touch enables outdoor usage and enhances user experience. In addition, it is able to use less power with advanced sleep and wake-up functionality, making it ideal for wearable and other battery-powered applications.
The software support provided by Microchip’s ecosystem further adds to the ease of use. The ATtiny817 is the first in a line to be supported by the Atmel START Code Configurator and the code-compact QTouch® modular library of firmware. As a web-based tool, Atmel START will enable users to always benefit from the latest state-of-the-art touch libraries.
“Microchip continues to be a leader in touch technology,” said Fanie Duvenhage, vice president of Microchip’s Touch Sensing Group. “In the creation of this newest peripheral touch controller, we wanted to push the boundaries on water resistance and noise immunity while keeping implementation easy for designers. What resulted was a top-of-the-line CIP that was an excellent addition to the ATtiny817/816/814 and will be an excellent addition to many MCUs in the future.”
