ATSAMA5D36A-CU

The ATSAMA5D36A-CU is an embedded microprocessor based on the ARM® Cortex®-A5 core running at up to 536 MHz. It combines a high-performance, power-efficient CPU architecture with integrated memory controllers, rich connectivity and hardware security to address industrial and consumer embedded designs.

Designed for applications that require advanced user interfaces, high levels of connectivity and secure boot/data handling, this industrial-grade MPU targets control panels, HMIs and networked embedded systems that benefit from compact, surface-mount packaging.

Key Features

• Core — ARM® Cortex®-A5 single core, 32-bit processor operating up to 536 MHz with an integrated floating point unit for accelerated numeric processing.
• Memory — High-bandwidth 32-bit multi-port dynamic RAM controller with support for LPDDR, LPDDR2 and DDR2; internal memory includes a 160 KB ROM and 128 KB SRAM as documented for the SAMA5D3 series.
• Display and UI — Integrated LCD controller with overlays and a touchscreen interface for hardware-accelerated image composition and touch-based user interfaces; CMOS sensor interface is available on the series.
• Connectivity — Multiple high-speed interfaces including Gigabit EMAC with IEEE1588 support, 10/100 EMAC, three USB 2.0 ports, and CAN plus standard serial buses (UART, SPI, I2C) as provided across the series.
• Security — Hardware-accelerated cryptography engines including AES, SHA and TDES, along with a true random number generator (TRNG) and secure boot mechanism for code protection and secure external data transfers.
• System and DMA — Multi-layer bus architecture with 39 DMA channels, including two 8-channel 64-bit central DMA controllers, supporting the high data bandwidth required by high-speed peripherals.
• Low-power features — Power-efficient design with low-power operating modes; series documentation reports sub-milliwatt power consumption in low-power mode for battery-sensitive applications.
• Package and Industrial Grade — 324-LFBGA (15 × 15 mm) surface-mount package rated for industrial temperature range of −40 °C to 85 °C.

Typical Applications

• Control Panels / HMIs — Drives graphical displays and touch interfaces with the integrated LCD controller and touchscreen support for responsive user interfaces.
• Industrial Networking — Handles Ethernet and CAN connectivity with Gigabit and 10/100 EMAC options, enabling networked controllers and distributed monitoring systems.
• Secure Embedded Systems — Enables secure boot and hardware-accelerated encryption and hashing for anti-cloning, code protection and protected external data transfers.
• Battery-powered Devices — Low-power modes and power management features make it suitable for portable or battery-conscious embedded products.

Unique Advantages

• High-performance single-core processing: A 536 MHz ARM® Cortex®-A5 core with VFP delivers efficient control and compute for embedded applications requiring floating-point capability.
• Comprehensive connectivity: Gigabit Ethernet, multiple USB 2.0 ports and CAN support provide flexible options for high-bandwidth and field communications.
• Integrated security stack: Hardware AES, TDES, SHA and TRNG plus secure boot reduce external components and simplify secure system design.
• Memory flexibility: Support for LPDDR, LPDDR2 and DDR2 plus MLC NAND support with up to 24-bit ECC (series feature) allows scalable memory configurations.
• Robust I/O throughput: A multi-layer bus with 39 DMA channels sustains high peripheral bandwidth while offloading the CPU.
• Industrial-ready packaging: 324-LFBGA surface-mount package and −40 °C to 85 °C operating range support deployment in industrial environments.
