ATSAMA5D31A-CUR

The ATSAMA5D31A-CUR is an ARM® Cortex®-A5 based embedded microprocessor IC delivering up to 536 MHz performance in a single 32-bit core. Designed for industrial-grade embedded systems, it combines high-performance processing, integrated connectivity and hardware security to support HMI, industrial control and connected devices.

Built with low-power modes and a high-bandwidth peripheral architecture, this Microchip Technology SAMA5D3 device targets designs that require efficient compute, flexible memory interfaces and robust security features in a 324-LFBGA package.

Key Features

• Core ARM® Cortex®-A5 single 32‑bit core running up to 536 MHz with an integrated Floating Point Unit (VFP).
• Memory Subsystem Internal boot ROM and SRAM plus a high-bandwidth 32-bit multi-port dynamic RAM controller supporting DDR2/LPDDR/LPDDR2 memory and an independent static memory controller with MLC NAND support and up to 24-bit ECC.
• Caches and MMU Instruction and data caches (32 KB each) with a fully integrated Memory Management Unit for virtual memory support.
• Peripherals & Interfaces Integrated display interface controllers for LCD and touchscreen. Three USB 2.0 ports and a 10/100 Mbps Ethernet interface provide common connectivity options. Additional interfaces include I2C.
• Security Hardware-accelerated cryptography including AES, SHA and TDES plus a True Random Number Generator (TRNG) and secure boot capability for code protection and secure data transfers.
• System, DMA & Timers High-throughput multi-layer bus architecture with 39 DMA channels to sustain processor and peripheral bandwidth; integrated timers, watchdog and real-time clock functions.
• Low-Power Design Architecture and power-management features support very low-power operation including shut-down and slow-clock modes suitable for battery-powered designs.
• Package & Temperature Supplied in a 324-LFBGA (15×15 mm) surface-mount package and rated for industrial operation from −40 °C to 85 °C.
• Grade & Compliance Industrial-grade device with RoHS compliance.

Typical Applications

• Human-Machine Interfaces (HMI) Drives LCD and touchscreen-based control panels with sufficient compute for responsive UI and image composition.
• Industrial Control & Monitoring Provides connectivity and real-time processing for PLC front-ends, protocol gateways and data acquisition modules.
• Secure Embedded Systems Hardware crypto engines and secure boot enable protected devices for secure communications and anti-cloning applications.
• Battery-Powered and Portable Devices Low-power modes and efficient processing allow extended operation in portable and remote embedded equipment.

Unique Advantages

• Highly integrated processing and I/O: Single-chip MPU with display, USB and Ethernet interfaces reduces BOM and simplifies board design.
• Robust memory support: Flexible DDR2/LPDDR/LPDDR2 and NAND controllers with ECC enable scalable memory configurations for varied storage and performance needs.
• Hardware security: On-chip AES, TDES, SHA and TRNG accelerate secure operations and protect code and data at runtime and during boot.
• Designed for industrial environments: Industrial temperature rating and surface-mount 324-LFBGA packaging support reliable deployment in fielded systems.
• High DMA throughput: Multi-layer bus architecture with 39 DMA channels sustains high peripheral and memory bandwidth without burdening the CPU.
