SAME70 in SAM Microcontrollers Family
The Microchip SAM E70 is a high-performance sub-family of ARM Cortex-M7 based microcontrollers designed for demanding automation and connectivity applications. These devices provide a significant performance leap over traditional Cortex-M4 designs by utilizing a dual-issue superscalar architecture with integrated Floating Point Unit and DSP extensions. Primarily used for industrial control and high-speed communications, the SAM E70 bridges the gap between traditional microcontrollers and application processors while maintaining real-time deterministic behavior and low-latency interrupt handling.
Variants within the SAM E70 sub-family primarily differ based on on-chip Flash density, ranging from 512KB to 2MB, and internal SRAM capacity. Packaging options vary from 64-pin QFN to 144-pin LFBGA, affecting the number of available GPIOs and peripheral multiplexing. Certain higher-tier variants include specialized security features or extended temperature ranges for industrial deployments, while entry-level members focus on core computational performance with reduced peripheral pin-counts.
