32-BIT ARM-BASED MICROPROCESSORS
SAMA5D4 Series SAMA5D41 /42 /43 /44
Description
The Sama5d4 Series Is A High-performance, Power-efficient Arm Cortex -a5 Processor-based Mpu Capable
Of Running At Up To 600 Mhz. It Integrates The Arm Neon Simd Engine For Accelerated Signal
Processing, Multimedia And Graphics, As Well As A 128 Kb L2-cache For High System Performance. The
device
Features The Arm Trustzone Enabling A Strong Security Perimeter For Critical Software, As Well As
several hardware security
FEATURES. The device also
Features Advanced User Interface And Connectivity Peripherals. The Sama5d4 Devices Have Three
Software-selectable Low-power Modes: Idle, Ultra-low-power, And Backup. In Idle Mode, The Processor
Is Stopped While All Other Functions Can Be Kept Running At Normal Operating Bus Frequency. In
Ultralow-power Mode, The Processor Is Stopped While All Other Functions Can Be Kept Running At
Minimum Operating Bus Frequency. In Backup Mode, Only The Real-time Clock, Real-time Timer, Backup
SRAM, backup registers, and wakeup logic are running. The SAMA5D4
Features An Internal Multi-layer Bus Architecture Associated With 32 Dma Channels To Sustain The
High Bandwidth Required By The Processor And The High-speed Peripherals. The Device Supports
Ddr2/lpddr/lpddr2 And Slc/mlc Nand Flash Memory With 24-bit Ecc. The Comprehensive Peripheral Set
Includes A 720p Hardware Video Decoder, An Lcd Controller With Overlays For Hardware-accelerated
Image Composition, A Resistive Touchscreen Function, And A Cmos Sensor Interface. Connectivity
Peripherals Include A Dual 10/100 Ethernet Mac With Ieee1588, Three Hs Usb Ports, Uarts, Spis And
I2Cs. Security
Features Protect The System Against Counterfeiting, Safeguard Sensitive Data, Authenticate Safe
Programs And Secure External Data Transfers. The Sama5d4 Series Is Optimized For Control Panel/hmi
Applications needing video playback and
Applications That Require High Levels Of Connectivity In The Industrial And Consumer Market. Its
security
FEATURES make the SAMA5D4 well suited for secure gateways or for the IoT.
