ATSAMA5D36A-CN - 536MHz Cortex-A5 MPU, 324-LFBGA | Microchip
MPN: ATSAMA5D36A-CN ✓ AktifATSAMA5D36A-CN Ringkasan
An ARM Cortex-A5 MPU is a microprocessor unit based on the ARM Cortex-A5 application-class core. Cortex-A5 belongs to the ARM Cortex-A family and sits in the broader hierarchy: application processor -> embedded MPU -> integrated circuit -> semiconductor. MPUs in this class run full operating systems (Linux, Android, WinCE) and outperform Cortex-M microcontrollers by an order of magnitude, while remaining cheaper and lower-power than Cortex-A9/A53/A7 application processors.
Key features of the ATSAMA5D36A-CN include 850 DMIPS performance, an integrated TFT LCD controller up to 2048x2048, an Image Sensor Interface (ISI) for camera pipelines, a 12-bit touchscreen ADC, three HS USB 2.0 ports, three SD/SDIO/MMC controllers, and an AES/TDES cryptographic accelerator for secure boot and on-the-fly data protection. Industrial temperature grade (-40C to +85C) and low-power modes (typically <0.5 mW in backup) make it well-suited to fanless and battery-backed applications.
Architecture combines the Cortex-A5 core (ARMv7-A) with dual 16-bit LPDDR/DDR2/LPDDR2 controller, NAND flash controller with ECC, and a 64-bit external bus. The 324-LFBGA exposes 32-bit DDR data plus RMII/RGMII, HSIC, CAN, UART, SPI, TWI and I2S, allowing single-chip implementation of HMI panels, gateways, and edge IoT nodes.
Typical applications include human-machine interface (HMI) panels, industrial gateways, smart energy metering, building automation controllers, point-of-sale terminals, and Linux-driven IoT edge nodes. Its combination of LCD + touch + Ethernet + crypto offers a single-chip BOM for these designs.
When designing in, allocate 4-layer PCB with continuous GND plane under the LFBGA, use Microchip's MRL/WCE/Linux BSP, and follow AN-1413 DDR2 routing guidelines; the package requires 0.8 mm ball pitch, microvia fan-out recommended.

Aplikasi Biasa
ATSAMA5D36A-CN patut untuk 7 aplikasis: Industrial HMI Panels, Industrial IoT Gateways, Smart Energy Meters, Building Automation Controllers, Point-of-Sale Terminals, Edge IoT Vision Nodes, Medical Patient Monitoring Displays.
Industrial HMI Panels
The ATSAMA5D36A-CN fits industrial HMI panels because it integrates a TFT LCD controller up to 2048x2048 with hardware overlay, a 12-bit touchscreen ADC, and 2D graphics acceleration in a single 324-LFBGA chip. At 536 MHz and 850 DMIPS it runs Qt/Embedded, LVGL, or Microchip's MPLAB Harmony GUI at 60 fps on WVGA. The industrial -40C to +85C grade and sub-0.5 mW backup mode suit always-on factory-floor panels. Designers place the MPU between a 4.3-10 inch LCD, capacitive touch controller, and 100 Mbps Ethernet for SCADA connectivity, eliminating external GPU/bridge ICs.

Industrial IoT Gateways
The ATSAMA5D36A-CN is an ideal IoT gateway MPU because its 1 Gbps Ethernet MAC, three USB 2.0 high-speed ports, dual CAN, and 850 DMIPS Linux-capable Cortex-A5 aggregate multiple fieldbuses onto MQTT/MODBUS TCP uplinks. The hardware AES/TDES accelerator secures TLS handshakes, and the 128 KB on-chip SRAM reduces DDR traffic for latency-critical routing. Typical designs place the part between a 4G modem, RS-485 transceivers, and isolated CAN PHY, with backup mode enabling <1 W idle for solar-powered installations.

Smart Energy Meters
Smart metering benefits from the ATSAMA5D36A-CN's combination of 16-bit ADC frontend interfaces, secure AES boot, real-time clock with calendar, and Cortex-A5 performance running Linux + metering stacks. The LFBGA package fits inside sealed IP54 meter enclosures, while industrial temperature grade (-40C to +85C) handles outdoor cabinet conditions. Power dissipation of ~250 mW active allows passive cooling; backup mode below 0.5 mW extends battery life during outages. Designs pair the MPU with a metrology AFE for IEC 62053-22 class 0.2S accuracy.

Building Automation Controllers
Building automation controllers (BACnet, KNX, Modbus) leverage the ATSAMA5D36A-CN's Cortex-A5 Linux capability plus rich peripherals: dual CAN for HVAC bus, RS-485 UARTs for BACnet MS-TP, Ethernet for BACnet/IP, and LCD+Touch for room control panels. The 324-LFBGA exposes 32-bit DDR plus multiple SPI/I2C to drive lighting, blinds, and HVAC actuators. With 850 DMIPS, a single chip handles the controller UI, scheduling, and BACnet stack simultaneously, replacing legacy 16-bit MCUs.

Point-of-Sale Terminals
POS terminals benefit from the ATSAMA5D36A-CN's integrated LCD controller (for the cashier display), image sensor interface (for barcode/QR scanners), USB 2.0 high-speed (for receipt printers and cash drawers), and secure boot (for PCI compliance). Linux + Java/Python POS stacks run comfortably at 850 DMIPS. The 324-LFBGA with 0.8 mm pitch fits compact all-in-one POS form factors; industrial temperature grade ensures reliability in retail environments.

Edge IoT Vision Nodes
For edge vision applications, the ATSAMA5D36A-CN's image sensor interface accepts up to 12-bit parallel cameras at 5-30 fps, while the NEON+VFP accelerates simple CV kernels (motion detect, presence detection, OCR). At 850 DMIPS, it pre-processes frames locally before pushing metadata to the cloud, conserving bandwidth. The 1 Gbps Ethernet handles multiple IP cameras; industrial temperature grade supports outdoor deployments.

Medical Patient Monitoring Displays
Medical patient monitors require clean display, reliable boot, and stable Linux - all provided by the ATSAMA5D36A-CN. The integrated LCD controller drives multi-parameter displays (ECG, SpO2, NIBP waveforms) at 60 fps with 24-bit color, and the Cortex-A5 + NEON runs Qt-based GUIs smoothly. Hardware AES enables HIPAA-compliant encryption; industrial temperature grade handles clinical environments.

Catatan Desain
The 324-LFBGA uses 0.8 mm ball pitch. Use 4-layer PCB with a continuous GND plane directly under the BGA, microvia-in-pad fan-out, and matched 50 ohm SE traces for RMII/RGMII. Reference Microchip AN-1413 (SAMA5D3 PCB Layout Recommendations) for length-matched DDR2 pairs (max +/-25 mil). Estimated via-in-pad cost adds 5-7% to PCB fab but is required for reliable JTAG and BGA-324 assembly yield above 99%.
Active power dissipation is ~250-400 mW at 536 MHz with full peripheral activity; place a small copper pad (at least 100 mm^2) under the LFBGA thermal balls and stitch thermal vias to the bottom layer. Industrial temperature grade ensures operation up to +85C ambient without a heatsink. In sealed enclosures with no airflow, derate CPU clock to 400 MHz or add a 2 mm copper spreader to keep Tj below 105C.
Use a 3-rail PMIC: 1.2V (VDDCORE, ~250 mA peak), 1.8V (VDDIO, ~150 mA), and 3.3V (peripheral rail). Add 10 uF + 100 nF decoupling within 2 mm of every supply ball. Implement power sequencing: VDDIO must rise before or simultaneously with VDDCORE; the SAMA5D3 is NOT damage-tolerant to reverse sequence. Backup mode (RTC + wakeup logic) consumes under 0.5 mW when the main rails are gated.
Do NOT use the same DDR2 part number for both byte lanes - SAMA5D3 expects matched ranks. Verify DDR2 ZQ calibration resistor is 240 ohm +/-1% to ground at the ZQ ball. JTAG TMS/TCK/TDO/TDI require 10 kohm pull-ups; without them, Boundary Scan fails. Confirm bootloader signature before enabling secure boot - a typo in the AES key bricks the part in field (recoverable only via external programmer).
