MCHPATSAMD20E17A-AU
Overview
The ATSAMD20E17A-AU is a low-power 32-bit microcontroller based on the ARM Cortex-M0+ processor, operating at a maximum frequency of 48MHz. It features 128KB of Flash memory and 16KB of RAM in a compact 32-TQFP package, providing a balance of performance and efficiency for power-constrained applications. This MCU includes versatile serial communication interfaces and high-resolution analog peripherals, including a 12-bit ADC and a 10-bit DAC.
Why Choose This Part
The SAM D20 series offers an Event System that allows peripherals to communicate directly without CPU intervention, reducing power consumption and latency. Its high integration of analog features and the hardware-based Peripheral Touch Controller simplifies BOM costs for designs requiring sophisticated user interfaces and sensor processing.
