The Atmelâ | SMART SAMA5D3 series is a high-performance, power-efficientembedded MPU based on the ARMâ Cortexâ-A5 processor, achieving 536 MHzwith power consumption levels below 0.5 mW in low-power mode. The devicefeatures a floating point unit for high-precision computing and accelerated dataprocessing, and a high data bandwidth architecture. It integrates advanced userinterface and connectivity peripherals and security features.
The SAMA5D3 series features an internal multi-layer bus architecture associatedwith 39 DMA channels to sustain the high bandwidth required by the processorand the high-speed per ipherals. The device offers support forDDR2/LPDDR/LPDDR2 and MLC NAND Flash memory with 24-bit ECC.
The comprehensive peripheral set includes an LCD controller with overlays forhardware-accelerated image composition, a touchscreen interface and a CMOSsensor interface. Connectivity peripherals include Gigabit EMAC with IEEE1588,10/100 EMAC, multiple CAN, UART, SPI and I2C. With its secure bootmechanism, hardware accelerated engines for encryption (AES, TDES) and hashfunction (SHA), the SAMA5D3 ensures anti-cloning, code protection and secureexternal data transfers.
The SAMA5D3 series is optimized for control panel/HMI applications andapplications that require high levels of connectivity in the industrial and consumermarkets. Its low-power consumption levels make the SAMA5D3 particularly suitedfor battery-powered devices.
There are five SAMA5D3 devices in this series. All other featuresare available on all derivatives; this includes the three USB ports as well as theencr...
