Description
AI
The Microchip's SAM416C microcontroller is a system-on-chip solution for smart energy applications built around two high performance 32-bit ARM® Cortex®-M4 RISC processors. These devices operate at a maximum speed of 120 MHz and feature 1024 Kbytes of embedded Flash, 152 Kbytes of SRAM and on-chip cache for each core. The dual ARM® Cortex®-M4 architecture allows for integration of application layer, communications layers and security functions in a single device, with the ability to extend program and data memory via a 16-bit external bus interface.
