ATSAME54N19A

The ATSAME54N19A is a high-performance 32-bit ARM Cortex-M4 microcontroller from Microchip Technology, featuring a maximum operating frequency of up to 120 MHz. It integrates a rich set of peripherals including two high-speed USB controllers (USB 2.0 OTG and Device), multiple serial communication interfaces (USART, SPI, I2C, LIN), and advanced analog capabilities such as a 12-bit ADC with up to 16 channels and a programmable gain amplifier. The device also includes a hardware cryptographic engine supporting AES, SHA-256, and RNG for secure data handling. This microcontroller is built on a 40 nm process technology, offering low power consumption in both active and sleep modes—ideal for battery-powered applications. It supports dynamic voltage scaling and has an extensive memory configuration: up to 512 KB of flash memory and 128 KB of SRAM, enabling efficient code execution and real-time processing. The chip includes a floating-point unit (FPU) and a single-cycle multiply-accumulate (MAC) unit, enhancing performance for signal processing and control algorithms. The ATSAME54N19A features a robust peripheral set for industrial and consumer applications, including a 16-channel DMA controller, flexible timer modules (TCs, TCBs), and a watchdog timer for system reliability. It also includes a security module with read-out protection, secure boot, and tamper detection mechanisms, making it suitable for applications requiring high integrity and protection against unauthorized access. Designed for demanding environments, the device operates across a wide supply voltage range (1.62V to 3.6V) and supports temperature ranges from -40°C to +105°C. Its pin-compatible package options (QFN64, QFP64, and LFBGA64) allow flexibility in board design and integration into space-constrained systems. The integrated debug interface (SWD/JTAG) simplifies development and testing, while the Atmel Studio and MPLAB X IDE support streamline firmware development. Common applications include motor control, industrial automation, medical devices, IoT gateways, smart meters, and automotive electronics where reliable real-time performance, low power, and enhanced security are critical. The ATSAME54N19A delivers a balance of performance, efficiency, and feature richness, making it a versatile choice for modern embedded systems.
