ATSAMA5D27C-CNRVAO

Microprocessors Overview

The ATSAMA5D27C-CNRVAO is an industrial-grade microprocessor from the SAMA5D2 series, based on the ARM Cortex-A5 core. It operates at a maximum frequency of 500 MHz with a 32-bit data bus width. The device features 128 kB L1 instruction and data caches, plus 128 kB L2 cache, alongside 128 kB internal RAM and 160 kB ROM. It supports floating-point operations and includes extensive security features such as ARM TrustZone and secure boot. The MPU is housed in a 289-pin LFBGA package (14x14 mm) and supports I/O voltages from 1.65 V to 3.6 V.

Microprocessors Feature Summary

• Integrates ARM TrustZone technology for hardware-based security isolation and secure boot capabilities.
• Includes multimedia processing extensions (NEON MPE) for efficient handling of audio and video streams.
• Supports multiple memory interfaces including LPDDR1/2/3, DDR2, DDR3, and QSPI for flexible system design.
• Features integrated Ethernet MAC and USB 2.0 High-Speed Interface Controller (HSIC) for connectivity.

Microprocessors Applications

• Industrial Linux-based control systems requiring robust security and real-time performance.
• Human-machine interface (HMI) panels utilizing LCD and touch screen controllers.
• Smart metering and utility infrastructure devices needing reliable long-term operation.
• Medical equipment requiring secure data handling and multimedia processing capabilities.

Microprocessors Procurement Notes

Verify the specific suffix 'VAO' indicates automotive or extended reliability specifications compared to standard variants. Confirm the package marking and date code align with project requirements. Ensure ESD protection measures are implemented during handling due to the fine-pitch LFBGA package. Cross-reference the latest datasheet revision for any silicon errata affecting signal integrity or power sequencing.

Microprocessors Selection Notes

Select this variant when automotive-grade reliability or extended temperature stability beyond standard industrial ranges is required. Compare against ATSAMA5D27C-CN if only standard industrial conditions suffice. Consider the ATSAMA5D27-SOM1 if system-level integration of memory and PHY reduces PCB complexity. Evaluate power consumption profiles against other Cortex-A5 implementations for battery-operated constraints.

Microprocessors Part Context

This component belongs to the Microchip SAMA5D2 family, designed for high-performance embedded applications. It complements lower-end SAM9 and higher-end SAMA7 series processors. The VAO suffix typically denotes specific qualification standards, distinguishing it from the standard CN or CU variants within the same architectural family.

Microprocessors Replacement Considerations

ATSAMA5D27C-CN serves as the standard industrial equivalent without the VAO suffix qualifications. ATSAMA5D27C-D1G-CU offers a System-in-Package solution with integrated memory. Direct pin-to-pin replacement requires verifying the specific environmental and reliability certifications mandated by the target application.
