SAM D microcontrollers (MCUs) are truly differentiated general-purpose microcontrollers that are ideal for many low-power, cost-sensitive industrial and consumer applications. These MCUs offer excellent interface and peripheral options with impressive low-power performance.
SAM D MCUs build on decades of innovation and experience in embedded Flash microcontroller technology. This series of MCUs not only sets a new benchmark for flexibility and ease-of-use but also combines the performance and energy efficiency of an Arm Cortex-M0+ based MCU with an optimized architecture and peripheral set.
Key Features
Arm Cortex-M0+ based MCU running up to 48 MHz
Flash memory densities range from 8 KB to 256 KB with SRAM ranging from 2 KB to 32 KB
Low power consumption at < 70 µA/MHz
Direct Memory Access (DMA) and Event system
Up to six flexible serial communication modules (SERCOMs) provide peripheral flexibility
The SAM D51 high- performance MCU series features the 32-bit Arm Cortex-M4F processor with Floating Point Unit (FPU) running at up to 120 MHz, up to 1 MB dual-panel Flash with ECC, and up to 256 KB of SRAM with ECC. This series of MCUS offers excellent interface options with class-leading power performance and integrated hardware security.
Key Features
Arm Cortex-M4F core running at 120 MHz with single precision FPU
Quad Serial Peripheral Interface (QSPI) with Execute in Place (XIP) support
