Microchip ATSAME70Q19B-AN High-Performance 32-bit Microcontroller for Industrial Applications

The demand for robust, high-performance embedded control solutions in industrial environments continues to grow, driven by the need for greater connectivity, real-time processing, and operational reliability. Addressing these complex requirements, Microchip Technology's ATSAME70Q19B-AN stands out as a premier 32-bit microcontroller unit (MCU) engineered specifically for demanding industrial applications.

At the heart of this MCU is the powerful ARM® Cortex®-M7 core, delivering exceptional computational performance at speeds up to 300 MHz. This processing muscle is critical for executing complex control algorithms, signal processing tasks, and real-time decision-making in equipment such as industrial automation systems, motor drives, and human-machine interfaces (HMIs). The core is further enhanced with double-precision floating-point unit (FPU) and a high-speed cache memory, significantly accelerating data-intensive operations.

Connectivity is a cornerstone of the ATSAME70Q19B-AN's design. It is equipped with a comprehensive set of peripherals essential for modern industrial systems. This includes Ethernet (GMAC) with IEEE® 1588 precision time protocol (PTP) support for synchronized network communication, dual CAN-FD controllers for robust in-plant networking, and multiple USARTs, SPIs, and I2Cs for interfacing with a vast array of sensors and actuators. For security, the MCU integrates a hardware-based cryptographic engine with AES, SHA, and TRNG, ensuring data integrity and confidentiality in connected applications.

Robustness and reliability are paramount in industrial settings. The ATSAME70Q19B-AN is built to operate in harsh conditions, featuring an extended temperature range and enhanced immunity to electrical noise. Its memory subsystem, comprising up to 2MB of dual-panel Flash and 384KB of SRAM, incorporates error code correction (ECC) for improved data reliability. The addition of a securable memory region with tamper detection capabilities protects intellectual property and sensitive data from unauthorized access.

Development is streamlined by Microchip's mature MPLAB® X IDE and Harmony v3 integrated software framework, which provides a flexible and open-set of libraries for simplifying the implementation of complex functionality, reducing development time, and mitigating risk.

ICGOOODFIND: The Microchip ATSAME70Q19B-AN is a top-tier microcontroller solution that successfully merges raw processing power with extensive connectivity and hardened security features. Its robust architecture tailored for harsh environments makes it an ideal choice for developers building next-generation industrial automation, transportation, and smart energy systems.
