ATSAMA5D27C-D5M-CU Обзор
An MPU is a CPU-centric integrated circuit that depends on external storage and peripherals, unlike a microcontroller (MCU) that integrates them on-die. The ATSAMA5D27C-D5M-CU sits in the hybrid System-in-Package category: it ships as a microprocessor but embeds DDR2 inside the BGA. Within the broader taxonomy, it is an application processor -> embedded microprocessor -> ARM Cortex-A SoC -> semiconductor IC. The SAMA5D2 series targets connected-embedded designs running Linux with mainline kernel support.
Key differentiating specifications include a 32-bit single-core ARM Cortex-A5 core with NEON media engine and hardware FPU, a 16-bit databus Peripheral Touch Controller (PTC), an embedded audio subsystem with I2S and class-D amplifier interface, an advanced 2D graphics accelerator, and a low-power architecture with multiple sleep modes. The 0.8 mm ball pitch simplifies escape routing on 4-layer PCBs versus finer-pitch BGA alternatives.
The architecture integrates dual Ethernet GMACs with 1588 PTP hardware timestamping, dual CAN-FD controllers, USB HSIC plus two USB 2.0 high-speed ports, three FLEXCOMs (configurable as USART/SPI/TWI), two SD/MMC interfaces, and an image sensor interface. Peripherals are routed through a multi-layer AHB/APB matrix for deterministic DMA-driven throughput. The low-leakage process supports battery-backed deployments.
Typical applications include industrial HMI panels, building automation gateways, smart energy concentrators, point-of-sale terminals, medical patient-monitoring displays, and IoT edge nodes running Linux. The integrated PTC enables robust touchscreens without an external touch controller IC.
When designing with this device, follow Microchip's SAMA5D2 hardware design checklist: respect the 0.8 mm BGA escape rules, generate a clean 1.2V core supply from a PMIC such as the MCP16502, and route any external peripherals with controlled impedance. The SiP removes external DRAM but the CPU still requires the Linux BSP and AT91Bootstrap to boot.
This page synthesizes Microchip datasheet parameters, current distributor pricing, drop-in SiP variants from the same SAMA5D2 family, and practical design notes not collated in any single manufacturer document, providing engineering-ready information for sourcing and board bring-up.

Заметки по проектированию
Estimated: power the ATSAMA5D27C-D5M-CU via the Microchip MCP16502 PMIC, which generates the 1.2V core rail, 1.8V DDR2 rail, and 3.3V I/O rail from a single 5V or higher input. The SiP integrates DDR2 but still requires the 1.2V and 1.8V supplies to power the logic and DRAM. A clean 1.2V core rail with low ripple (<30 mV) is critical for Cortex-A5 jitter performance. Decouple each supply pin with 100 nF X7R ceramic placed as close to the BGA balls as the 0.8 mm pitch allows.
Design the PCB for the 0.8 mm BGA escape: use microvia-in-pad (VIP) on inner pads if the stackup supports it, or dog-bone fanout to a 0.5 mm via-pitch inner layer. Per Microchip's SAMA5D2 hardware design guide, route all DDR2 signals (now internal to the SiP) first but allow escape room for the high-speed USB 2.0 differential pairs, GMAC RGMII to the Ethernet PHY, and the parallel LCD RGB bus if used. Maintain 90 ohm differential impedance for USB and 50 ohm single-ended for RGMII.
Place the MCP16502 PMIC and the LAN8742A Ethernet PHY on the bottom side of the PCB directly under the ATSAMA5D27C-D5M-CU BGA to minimize loop area on the 1.2V core rail. Route the GMAC RGMII traces with matched lengths (within 50 mil) and keep the 25 MHz reference clock trace short and well-shielded. Per the SAMA5D2 hardware checklist, leave the SDRAM-via region isolated and avoid routing analog audio (I2S, class-D) traces across noisy power regions.
Estimated: under typical Linux HMI workloads at 500 MHz, the ATSAMA5D27C-D5M-CU dissipates roughly 0.5-0.8 W, depending on which peripherals are enabled. The 289-LFBGA.15 mm package has a theta-JA of approximately 25 C/W on a standard 4-layer JEDEC PCB, giving a junction-to-ambient rise of 12-20°C at industrial ambient. Thermal vias under the center ground balls reduce junction temperature in enclosed industrial enclosures.
Do not confuse the ATSAMA5D27C-D5M-CU (with SiP DDR2) for the ATSAMA5D27C-CU (without SiP DDR2) - the latter requires external DDR2 PCB routing and a different bootloader configuration. Per the Microchip SAMA5D2 datasheet, software bring-up requires AT91Bootstrap, U-Boot, and the Linux4SAM kernel; missing these steps leads to boot failures. Also verify the OTP memory configuration and disable JTAG in production builds to secure the device.
