Built around the ARM Cortex-M4 core, the ATSAM4SA16BA-MU operates at 120MHz and integrates Atmel"s Flash read accelerator and optional cache memory to increase system performance. The ATSAM4SA16BA-MU features a multi-layer bus matrix, multi-channel direct memory access (DMA) and distributed memory to support high data rate communication. Devices are pin-to-pin and software compatible with current SAM3S Cortex-M3-based MCUs, offering a smooth upwards migration path for performance and memory size.
Integrated best-in-class hardware code protection
Unique 128-bit ID
Supports secure device reconditioning (chip erase) for reprogramming
Rich peripheral set for connectivity, system control and analog interfacing
