ATSAMA5D22B-CU

The ATSAMA5D22B-CU is a single-core, 32-bit microprocessor based on the ARM® Cortex®-A5 core running at 500 MHz. It is packaged in a 196-TFBGA (11×11) surface-mount package and is part of the SAMA5D2 series from Microchip Technology.

Designed for embedded systems, the device combines performance, integrated multimedia acceleration and extensive security features with a broad set of peripheral interfaces and memory controller support, making it suitable for industrial-temperature embedded applications.

Key Features

• Core  ARM® Cortex®-A5 single core, 32-bit at 500 MHz for deterministic embedded processing.
• Memory Support  Supports LPDDR1/LPDDR2/LPDDR3, DDR2, DDR3, DDR3L and QSPI memory interfaces to match a range of memory architectures.
• Multimedia & DSP Acceleration  Includes multimedia co-processor support and NEON™ MPE for enhanced media and signal-processing tasks.
• Display & HMI  Built-in display interface controllers for keyboard, LCD and touchscreen integration plus graphics acceleration for GUI implementations.
• Connectivity  Integrated 10/100 Mbps Ethernet (1), USB 2.0 with HSIC and I2C for common peripheral and network connections.
• Security  Hardware security features including ARM TrustZone (TZ), boot security, cryptography, RTIC, secure fusebox, secure JTAG, secure memory and secure RTC for protected boot and runtime operation.
• Power & I/O  3.3 V I/O voltage compatibility for standard embedded logic interfacing.
• Package & Temperature  196-TFBGA (11×11) CSBGA surface-mount package rated for industrial operation from -40 °C to 85 °C.

Typical Applications

• Industrial Embedded Systems  Leverages the industrial temperature range and Ethernet connectivity for machine controllers, gateways and instrumentation.
• Human–Machine Interfaces (HMIs)  LCD, touchscreen and keyboard controllers with graphics acceleration enable responsive operator interfaces.
• Secure Communications  On-chip security features and cryptography support protected boot and secure networked devices.
• Multimedia and Signal Processing  NEON™ MPE and multimedia co-processor support for audio, image or other media-processing tasks in embedded products.

Unique Advantages

• Integrated security suite: Combines ARM TrustZone, secure boot, cryptography and secure JTAG to reduce external security components and simplify secure system design.
• Versatile memory interface: Broad support for LPDDR, DDR and QSPI memories allows designers to choose cost and performance trade-offs without changing the MPU family.
• Embedded connectivity: Native 10/100 Mbps Ethernet plus USB 2.0 and I2C reduce the need for additional interface controllers.
• Industrial temperature rating: -40 °C to 85 °C operation provides suitability for industrial-grade deployments.
• Compact BGA package: 196-TFBGA (11×11) surface-mount package saves board area while providing robust pin count for complex systems.
