ATSAMA5D35A-CNR

The ATSAMA5D35A-CNR is an embedded microprocessor IC based on a single ARM® Cortex®-A5 core running up to 536 MHz. It combines a compact 324-LFBGA (15×15) package with integrated memory controllers, advanced connectivity, and hardware security to address industrial and consumer embedded designs.

Designed for user-interface and connected applications, the device targets control panels/HMI, connected gateways and battery-powered systems that require balanced performance, low-power operation, and on-chip integration of peripherals and security engines.

Key Features

• Core and CPU Subsystem  ARM® Cortex®-A5 single 32-bit core up to 536 MHz with VFPv4 floating point unit, 32 KB instruction and 32 KB data caches, and integrated MMU for protected virtual memory.
• Memory and Boot  High-bandwidth 32-bit multi-port DRAM controller supporting DDR2/LPDDR/LPDDR2 (up to 512 MB, 8-bank) with datapath scrambling; internal 160 KB ROM with embedded boot loader and 128 KB internal SRAM. Independent static memory controller with support for SLC/MLC NAND and up to 24-bit ECC (PMECC).
• Display and Imaging  Integrated LCD controller with overlays for hardware-accelerated image composition and a touchscreen interface plus CMOS sensor interface to support rich HMI designs.
• Connectivity  Multiple high-speed interfaces including Gigabit EMAC (with IEEE‑1588), 10/100 EMAC, three USB 2.0 ports, multiple CAN, UART, SPI and I2C peripherals for broad system integration.
• Security  Hardware accelerated engines for AES, TDES and SHA, a true random number generator (TRNG) and secure boot mechanisms to protect code integrity, enable encrypted storage and secure external transfers.
• System and Real-Time Support  Multi-layer bus architecture with 39 DMA channels (including two 8-channel 64-bit CDMA controllers), 64-bit advanced interrupt controller, watchdog timer, real-time clock and multiple PLLs for optimized timing and throughput.
• Low-Power and Power Management  Integrated power management features including shut down controller, battery backup registers, and very-low-power operating modes (series-level low-power consumption below 0.5 mW reported in low-power mode).
• Package and Environmental  324-LFBGA surface-mount package (15×15); Industrial grade with operating temperature range −40 °C to 105 °C and RoHS compliant.

Typical Applications

• Industrial HMI and Control Panels  Drives LCD and touchscreen interfaces and provides the connectivity and security required for modern operator panels and machine interfaces.
• Connected Gateways and Network Appliances  Gigabit Ethernet and multiple USB/CAN interfaces enable networked edge devices and protocol bridging in industrial and consumer networks.
• Battery-Powered and Portable Systems  Low-power operating modes and integrated power management make it suitable for battery-constrained embedded products that still require high processing efficiency.
• Secure Embedded Systems  On-chip encryption, hashing and TRNG with secure boot support protect firmware and external data flows in security-sensitive applications.

Unique Advantages

• Balanced Performance and Efficiency: A 536 MHz Cortex‑A5 core with VFPv4 delivers compute capability while series-level low-power modes keep idle consumption minimal.
• Highly Integrated Memory Subsystem: Multi-port DRAM controller, internal ROM/SRAM and NAND support with 24-bit ECC reduce external component count and simplify boot/storage design.
• Comprehensive Connectivity: Gigabit Ethernet, multiple USB ports, CAN and common serial buses enable diverse I/O requirements without extensive external logic.
• Built-in Security Primitives: Hardware AES/TDES/SHA engines, TRNG and secure boot provide a foundation for anti‑cloning and code protection directly on-chip.
• Robust System Management: Extensive DMA channels, interrupt architecture, timers and PLLs allow deterministic handling of high-throughput peripherals and real-time tasks.
• Industrial Temperature Range: Rated −40 °C to 105 °C to meet deployment needs in demanding operating environments.
