SAMA5D3 Series
Atmel | SMART ARM-based MPU
DATASHEET
Description
The Atmel | SMART SAMA5D3 series is a high-performance, power-efficient
embedded MPU based on the ARM Cortex -A5 processor, achieving 536 MHz
with power consumption levels below 0.5 mW in low-power mode. The device
features a floating point unit for high-precision computing and accelerated data
processing, and a high data bandwidth architecture. It integrates advanced user
interface and connectivity peripherals and security features.
The SAMA5D3 series features an internal multi-layer bus architecture associated
with 39 DMA channels to sustain the high bandwidth required by the processor
and the high-speed peripherals. The device offers support for
DDR2/LPDDR/LPDDR2 and MLC NAND Flash memory with 24-bit ECC.
The comprehensive peripheral set includes an LCD controller with overlays for
hardware-accelerated image composition, a touchscreen interface and a CMOS
sensor interface. Connectivity peripherals include Gigabit EMAC with IEEE1588,
10/100 EMAC, multiple CAN, UART, SPI and I2C. With its secure boot
mechanism, hardware accelerated engines for encryption (AES, TDES) and hash
function (SHA), the SAMA5D3 ensures anti-cloning, code protection and secure
external data transfers.
The SAMA5D3 series is optimized for control panel/HMI applications and
applications that require high levels of connectivity in the industrial and consumer
markets. Its low-power consumption levels make the SAMA5D3 particularly suited
for battery-powered devices.
There are five SAMA5D3 devices in this series. Table SAMA5D3 Device
Differences shows the differences in the embedded features. All other features
are available on all derivatives; this includes the three USB ports as well as the
encryption engine and secure boot features.
