AT91SAM ARM-based Embedded MPU
SAMA5D3 Series
PRELIMINARY SUMMARY DATASHEET
Description
The Atmel 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 four SAMA5D3 devices in this series. The following table 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.
