Product Description
The Microchip ATSAM4S8CA-AU is a 32-bit ARM Cortex-M4 based microcontroller from the SAM3S family, engineered for high-performance and embedded industrial applications. Housed in a 100-pin LQFP package, this device balances computational power, memory resources, and peripheral integration in a compact footprint suitable for surface mounting on custom PCBs.
At the heart of this microcontroller is a powerful ARM Cortex-M4 processor core, operating at a maximum clock frequency of 50 MHz. This architecture ensures efficient signal processing and support for real-time industrial control systems, instrumentation, and automation platforms. The device features a generous 512 kB of embedded Flash program memory, allowing extensive application code and data to be securely stored and executed at speed, supported by 128 kB of SRAM for rapid data access during runtime.
Designed for versatile connectivity and complex embedded applications, the ATSAM4S8CA-AU integrates multiple interfaces, including UART, 1-Wire, JTAG, parallel port, and full-speed USB. These interfaces streamline communication with external components, facilitate debug operations, and allow seamless integration into industrial, scientific, and commercial electronics ecosystems.
The microcontroller includes 16-channel 12-bit ADCs and a 12-bit DAC, enabling accurate analog signal acquisition and output, ideal for sensor interfacing and signal control applications. With 79 programmable I/O pins, engineers can flexibly map peripherals and custom functions as project requirements evolve. Tolerance to temperature extremes from -40°C to +85°C, and operation across a supply voltage range of 1.62 V - 3.6 V, ensure reliability in harsh environments typical of industrial sites, manufacturing lines, instrumentation enclosures, and remote field modules.
Surface-mount LQFP packaging (14 x 14 x 1.45 mm) allows compact PCB design and automated assembly for volume production. The robust feature set, including RISC instruction set, integrated hardware code protection, advanced timers, and digital/analog conversion capabilities, makes this device well-suited for control panels, data loggers, smart instrumentation, industrial controllers, laboratory equipment, and advanced hobbyist platforms.
Engineers can deploy the Microchip ATSAM4S8CA-AU microcontroller for applications in industrial automation, process controls, laboratory instrumentation, robotics, textile machinery, test/measurement systems, and commercial embedded devices.
