Touch enabled through the same easy development flow used with the ARM Cortex-M0+ based SAM D20, D21 and D10/D11 devices.First 5V Atmel devices with PTC-enabled capacitive touch.Key Features – Atmel | SMART SAM C20 and SAM C21 In addition to 5V operation and greatly improved noise immunity, SAM C20 and C21 MCUs offer faster response times and support for more self-capacitance channels. These devices raise the conducted immunity bar by passing at a test level of 15V, exceeding the highest IEC/EN 6 test level of 10V. QTouch support is enabled through QTouch Library 5.7 and QTouch Composer 5.7. By addressing applications that require 5V operating voltage, these MCUs enable Atmel to further build on the huge home appliance market success achieved by the Atmel SMART SAM D20 series. Atmel Launches 5V Peripheral Touch Controller Support Expands QTouch Offering for Home Appliance and Industrial MarketsĪtmel has extended the Atmel® QTouch® portfolio with additional support for the Atmel® SMART SAM C20 and SAM C21 ARM ® Cortex ®-M0+ based microcontrollers (MCUs), establishing a milestone as the first 5V Peripheral Touch Controller (PTC) devices.
