Active265 in stock

Overview

The ATSAMA5D27C-D1G-CU is a high-performance, ultra-low-power Arm Cortex-A5 based microprocessor (MPU) operating at 500MHz. It is part of the SAMA5D2 series and features an integrated 1Gb (128MB) DDR3L SDRAM in a single TFBGA289 package, significantly reducing PCB complexity and EMI. This MPU is designed for secure, power-efficient industrial and IoT applications requiring sophisticated user interfaces and robust security through Arm TrustZone technology.

Why Choose This Part

The primary advantage is the System-in-Package (SiP) design, which integrates 128MB of DDR3L RAM to eliminate the challenges of high-speed memory routing on the PCB. It offers a rich set of connectivity options including 10/100 Ethernet, USB 2.0 High-Speed, and extensive graphics support via the NEON Media Processing Engine. Hardware security is a core focus, with features like scrambled internal SRAM, secure boot, and a hardware encryption engine.

Applications

Secure IoT Gateways
Leverages Arm TrustZone and hardware encryption to manage secure data routing and edge connectivity.
Industrial Human Machine Interface (HMI)
Utilizes the integrated LCD controller and touchscreen support to drive interactive industrial control panels.
Point-of-Sale (POS) Terminals
Employs hardware security features and tamper detection for handling sensitive financial transactions.
High-End Home Automation
Acts as a central controller for smart home ecosystems requiring video processing and multiple communication interfaces.

Getting Started

Developers can evaluate the platform using the SAMA5D27-SOM1-EK1 evaluation kit, which hosts the System-on-Module variant of this chip. Software development is supported through the Mainline Linux distribution or the Microchip MPLAB Harmony v3 framework for RTOS-based applications. Debugging is typically performed using the J-Link or MPLAB ICE 4 via the standard JTAG/ICE interface.
