Overview

The ATSAMDA1E16B-ABT is a 32-bit ARM Cortex-M0+ microcontroller operating at 48MHz, designed specifically for automotive and functional safety applications. It features 64KB of Flash and 8KB of RAM, integrated into a compact 32-pin TQFP package for space-constrained designs. This device includes specialized hardware like the Peripheral Touch Controller and SleepWalking peripherals to maintain high efficiency and safety standards.

Why Choose This Part

The SAM DA1 series offers a unique combination of automotive qualification and the energy-efficient ARM Cortex-M0+ core. It includes an Event System that allows peripherals to communicate without CPU intervention, reducing latency and power consumption. The integrated 12-bit ADC with oversampling and decimation enables high-precision analog measurements without additional external components.

Applications

Automotive Interior Control
Ideal for controlling LED lighting, door modules, and mirror adjustments while meeting automotive reliability requirements.
Capacitive Touch Interfaces
Utilizes the integrated Peripheral Touch Controller (PTC) for robust buttons, sliders, and wheels in industrial or automotive cabins.
Functional Safety Controllers
Suitable for safety-critical tasks requiring hardware CRC-32 and Brown-out detection to ensure system integrity.
Low-Power Sensor Nodes
Leverages SleepWalking technology to allow peripherals to wake the CPU only when necessary, extending battery life in remote monitoring.
