ATSAMA5D27C-CN

The ATSAMA5D27C-CN is an ultra-low-power microprocessor unit based on a single ARM® Cortex®‑A5 core running up to 500 MHz. It integrates a rich set of memory controllers, display and sensor interfaces, connectivity peripherals and hardware security features to address embedded applications that require performance, integration and secure operation.

Designed for industrial-grade operation with an extended temperature range and a compact 289‑LFBGA (14×14) surface-mount package, the device targets systems that need multimedia processing, user interfaces and robust connectivity while maintaining low-power operation.

Key Features

• Core & Architecture — Single ARM® Cortex®‑A5 32‑bit core with NEON™ media processing engine and up to 500 MHz operation.
• Memory & Storage — High flexibility with controllers for LPDDR1/2/3, DDR2/DDR3/DDR3L and QSPI flash; internal caches and SRAM/ROM options described in the datasheet support boot and runtime needs.
• Graphics & Display — Integrated LCD/TFT controller with rotation, overlays and post‑processing; supports touchscreen and keyboard interfaces and hardware graphics acceleration.
• Connectivity & Peripherals — Includes 10/100 Mbps Ethernet (single port), USB 2.0 with HSIC support, I2C, image sensor controller (up to 5 M‑pixel support in series datasheet), audio interfaces and multiple synchronous serial controllers.
• Security & Trusted Boot — ARM TrustZone, boot security, cryptographic accelerators (AES, SHA, TRNG noted in datasheet), secure fusebox, secure JTAG, secure memory and secure RTC for hardened platform security.
• System & Low‑Power Features — Multiple low‑power modes with fast wakeup, RTC, watchdog and extensive DMA/channel support to optimize system efficiency and responsiveness.
• Package & Environmental — 289‑LFBGA (14×14) surface‑mount package; industrial operating temperature range from -40 °C to 105 °C and RoHS compliance.

Typical Applications

• Human‑Machine Interfaces (HMI) — Drives LCD/TFT displays with touchscreen and keyboard input, supporting rich graphics and responsive user experiences.
• Industrial Automation — Industrial‑grade temperature range and extensive I/O/connectivity make it suitable for control panels, operator consoles and embedded controllers.
• Secure Edge Devices — Hardware TrustZone and on‑chip cryptography enable secure boot, encrypted storage and trusted execution for edge security gateways and data concentrators.
• Multimedia & Vision — NEON MPE, image sensor controller and audio interfaces support multimedia processing, camera capture and local vision tasks.

Unique Advantages

• Highly integrated processing platform: Combines a 500 MHz Cortex‑A5 core with memory controllers, display engines and connectivity to reduce external components and BOM.
• Hardware security stack: Built‑in TrustZone, secure boot and cryptographic accelerators provide foundation for secure product designs and protected firmware.
• Memory flexibility: Native support for multiple DDR and LPDDR generations plus QSPI flash enables designers to match memory technology to cost and performance targets.
• Industrial temperature support: Specified operation from -40 °C to 105 °C supports deployment in demanding environmental conditions.
• Low‑power operation with fast wakeup: Ultra‑low‑power modes and sleepwalking features enable energy‑efficient designs with responsive wake behavior.
