ATSAM4C16CA-AU - Dual Cortex-M4 120MHz 1MB MCU | Microchip
The Microchip Technology ATSAM4C16CA-AU is a 32-bit dual-core ARM Cortex-M4 flash microcontroller with 1MB (1M x 8) flash memory, 120MHz maximum CPU speed, and a 74-I/O 100-LQFP (14x14 mm) surface-mount package.
A microcontroller (MCU) is a single integrated circuit that combines a processor core, program memory, data memory, and peripherals into one chip, forming the highest-volume segment of the embedded systems and power management IC hierarchy. The SAM4C family extends Microchip's (formerly Atmel) ARM-based SAM line by pairing two Cortex-M4 cores in one device, allowing one core to run the main application while the second handles communication, math acceleration, or safety tasks.
Key features of the ATSAM4C16CA include the 32-bit dual-core Cortex-M4 architecture with DSP and floating-point extension, 120MHz operating frequency, 1MB embedded flash, connectivity peripherals including EBI/EMI external bus, I2C, IrDA, SPI, and UART/USART, plus brown-out detect/reset, DMA, LCD controller, POR, PWM, and watchdog timer peripherals.
The dual-core CM4F implementation enables true parallel processing: each core executes SIMD and hardware FPU instructions, useful for motor control algorithms, cryptography, and digital signal processing without a separate DSP. Program memory is organized as 1M x 8 flash, and the device operates from a 1.2V/3.3V supply per distributor specification data.
Typical applications include industrial automation, motor control with encoder feedback, LCD-based human-machine interfaces leveraging the integrated LCD controller, and communication-intensive IoT gateways using multiple UART/USART channels.
Design consideration: verify flash density and I/O count against the pin-compatible SAM4C siblings (ATSAM4C8CA at 512KB, ATSAM4C32CA at 2MB) since the 100-LQFP footprint allows same-board memory migration.
