ATSAMA5D26A-CUR - 500MHz Cortex-A5 MPU, 289-LFBGA | Microchip

The Microchip ATSAMA5D26A-CUR is a high-performance, low-power ARM Cortex-A5 microprocessor (MPU) running at up to 500 MHz, housed in a 289-pin LFBGA (14x14 mm) package. It integrates 128 KB SRAM, 160 KB ROM, and a rich peripheral set including DDR2/DDR3L/LPDDR2/LPDDR3 controllers, QSPI and e.MMC flash interfaces, dual EMAC, USB, CAN-FD, and advanced security/crypto accelerators. An ARM Cortex-A5 MPU is a microprocessor unit built on the ARMv7-A architecture - a Harvard-style superscalar core with MMU, caches, and optional NEON/FPU. MPUs run full operating systems (Linux, Android, RTOS) on external memory, distinguishing them from microcontrollers (MCUs) which typically execute firmware from internal flash with no MMU. The Cortex-A5 sits in the low-power end of the application-processor hierarchy (Cortex-A5 -> Cortex-A family -> ARM application processors -> 32-bit embedded processors -> semiconductors), targeting HMI, IoT gateways, and industrial control where deterministic power and small die area matter more than raw performance. Key features include the SAMA5D2 series' hardware cryptography block (AES, SHA, TRNG), secure boot, tamper detection pins, and an LCD controller supporting up to WXGA. The 289-LFBGA package exposes the full SAMA5D26 signal set including dual CAN-FD, three FLEXCOMs (USART/SPI/TWI), two I2S, and 12-bit ADC, enabling direct connection to industrial sensors, displays, and wired networking without external bridges. Architecturally, the SAMA5D26 uses a single-issue, in-order Cortex-A5 core with NEON and FPU, fed by 32 KB instruction and 32 KB data caches backed by a 128 KB system SRAM. The Advanced Interrupt Controller (AIC) and a frequency-scalable LDO allow run, idle, and ultra-low-power modes, while the peripheral DMA controller offloads data movement from the CPU. The hardware crypto block accelerates AES up to 256-bit, SHA-1/256, and provides a true random number generator suitable for TLS key exchange. Typical applications include industrial HMI panels, smart energy gateways, building automation controllers, POS terminals, and IoT edge nodes running Linux. Designers choose the SAMA5D26 over Cortex-M4/M7 MCUs when an MMU and OS are required, and over Cortex-A53/A72 MPUs when power budget or BOM cost dominates. Design consideration: route DDR signals first with length-matched impedance-controlled traces, and dedicate at least one full ground plane beneath the BGA. Decouple each VDD/VBAT/VDDANA pin with a 100 nF ceramic cap as close to the balls as practical.

The Microchip ATSAMA5D27A-CUR is a 32-bit ARM Cortex-A5 microprocessor (MPU) from the SAMA5D2 series running at up to 500 MHz, packaged in a 289-ball LFBGA (14x14 mm, 0.8 mm pitch) and offered on Tape & Reel. It integrates a single Cortex-A5 core with NEON, FPU, 32 KB I-cache and 32 KB D-cache, plus dedicated SRAM and a peripheral touch controller, and supports external memories including DDR2, DDR3L, LPDDR2, LPDDR3, QSPI and e.MMC. What is an ARM Cortex-A5 MPU? A microprocessor (Microprocessing Unit, MPU) is a CPU-centric system-on-chip that requires external DRAM and flash for program execution and data storage, as opposed to a microcontroller (MCU) which integrates non-volatile memory on-die. Cortex-A5 is an ARMv7-A application-class core positioned above Cortex-M microcontrollers but below Cortex-A7/A9/A53 in performance; it executes Linux, Android and RTOS with hardware virtualization, full MMU and the NEON SIMD engine. Within the power-management hierarchy of an embedded system, the MPU is the highest-power computational block and drives dynamic voltage scaling to balance battery life against workload. Key features include hardware AES-OTF (on-the-fly encryption) for secure boot and storage, HSIC USB, two CAN-FD controllers, an embedded audio subsystem with I2S/TDM, and a simple power management scheme with 5 uA backup mode current. The 0.8 mm ball pitch package reduces PCB design complexity compared with finer-pitch BGAs, easing layout for cost-sensitive industrial designs. The device targets industrial temperature range (-40 C to +85 C, MRLA marking) and operates at 105 C junction maximum, enabling use in fanless enclosures. Its peripheral mix - CAN, HSIC, AES-OTF, FPU, NEON - is optimised for connected industrial gateways, low-power HMIs, and battery-backed IoT edge nodes. Typical applications include industrial IoT gateways, smart energy meters, building automation controllers, HMI panels and connected medical device interfaces. A simple power scheme plus CAN-FD support makes it well suited for factory automation. Design consideration: PCB layout for the 14x14 LFBGA with 0.8 mm pitch requires 4-layer stack-up with microvia fan-out and matched-length DDR traces for DDR2/DDR3L; route the high-speed USB/HSIC and Ethernet pairs with controlled impedance 90 ohm differential.

The Microchip Technology ATSAMA5D27B-CU is a high-performance, low-power Arm Cortex-A5 microprocessor (MPU) running up to 500 MHz, delivered in a 289-pin LFBGA (14x14 mm, 0.8 mm ball pitch) package. It integrates peripherals for the SAMA5D2 family, including a TFT LCD controller, 2D graphics engine, embedded audio subsystem, peripheral touch controller, CAN-FD, Gigabit Ethernet MAC, and a 720p hardware video decoder (H.264), making it a strong fit for HMIs, edge gateways, and industrial graphics terminals. An MPU (microprocessor unit) is a class of system-on-chip that integrates a full applications-grade CPU with memory controllers and rich I/O. The Cortex-A5 generation is a 32-bit superscalar core that runs the Linux kernel and other rich operating systems, sitting above microcontrollers (MCUs) in capability and above DSPs in generality. The SAMA5D2 series in particular targets low-power, fanless embedded designs where an MPU must run from constrained supplies or backup batteries. Key features include 32-bit DDR2/DDR3L/LPDDR2/LPDDR3 memory controller, 16-bit SLC NAND controller with ECC, dual CAN-FD controllers, 10/100/1000 Ethernet MAC with 1588 PTP timestamps, three HS USB ports, multiple I2S/TWI/SPI/UART, secure boot, hardware cryptographic accelerators (AES, SHA, TRNG), and an AES/secure boot chain. Operation voltage is typically 1.2 V core with 1.8 V/3.3 V I/O, and total system power in backup mode can drop to about 5 µA. The architecture pairs the Cortex-A5 core with a 32 KB I-cache and 32 KB D-cache plus NEON and FPU (where present), an MMU for Linux, and a low-latency bus matrix that keeps the LCD and Ethernet streams fed under sustained interrupt load. This combination is tuned for low BOM cost designs, since most peripherals needed for a connected display product are integrated. Typical applications include industrial HMI panels, building automation gateways, smart-grid concentrators, vending and ticketing terminals, medical point-of-care displays, and rugged portable instruments with LTE connectivity. The compact 14x14 mm BGA footprint enables compact carrier boards, while the 0.8 mm ball pitch reduces PCB layer count compared with finer-pitch MPUs. A key design consideration is the memory topology and power sequencing: VDDANA, VDDBU, VDDPLL, VDDOSC, and the DDR rail must be brought up in the order described in the SAMA5D2 datasheet, otherwise the boot ROM may not initialize the DRAM reliably. Use a sequencing supervisor or the bundled SAM software package reference design.

It operates from a typical 1.2 V core supply and targets industrial, automotive, and connected-embedded designs requiring deterministic Linux performance. What is an MPU? An embedded microprocessor unit (MPU) is a CPU-centric system-on-chip that requires external memory and peripherals, in contrast to a microcontroller (MCU) which integrates flash and I/O on-die. MPUs typically run higher-level operating systems (Linux, Android, RTOS) at hundreds of MHz to GHz speeds, and occupy the tier above microcontrollers in the embedded hierarchy: MPU -> microprocessor -> SoC -> integrated circuit -> semiconductor. The SAMA5D2 family in particular targets secure-connected edge nodes and HMI panels where Cortex-A class performance is needed without the power of an application processor. Key features include a single Arm Cortex-A5 core with Neon and FPU, hardware cryptography accelerator (AES, SHA, TRNG), dual CAN-FD interfaces, dual Gigabit Ethernet with AVB/TSN support, USB 2.0 high-speed host and device, multiple UART/SPI/I2C, a 12-bit ADC, and a CMOS camera interface. The peripheral set is tailored for industrial gateways and graphical HMI, while advanced security features include secure boot, tamper detection, and on-die key storage - meeting IEC 62443-style requirements for industrial security. At 500 MHz the device consumes on the order of a few hundred milliwatts active, with deep-sleep retention modes dropping consumption into the milliamp range for battery-backed always-on duty cycles. The 289-LFBGA package requires careful PCB stack-up and 0.8 mm ball pitch routing, but Microchip provides a full Linux distribution (mainline-based), a bare-metal SDK, and reference schematics to accelerate bring-up. Typical applications include industrial IoT gateways, building automation controllers, smart-home concentrators, POS terminals, medical patient monitors, and graphical HMI panels. Its dual GbE and CAN-FD capability also make it attractive for vehicle telematics and fleet-management edge nodes. When designing with the ATSAMA5D27B-CUR, ensure the PCB has impedance-controlled DDR traces, a clean 1.2 V core rail with adequate bulk decoupling, and a properly sequenced power-up; the integrated boot ROM supports QSPI, e.MMC, SD card, and NAND bootstrap, so firmware planning can defer storage choice to later in the design cycle.

The device operates from a single 1.2 V core supply with separate I/O and DDR rails. Architecturally, the SAMA5D27C-CN combines the Cortex-A5 core with a multi-layer AHB/AXI fabric, dedicated peripheral DMA channels, and a low-power backup domain containing a 32 kHz real-time clock and tamper pins. The hardware crypto block executes AES-256, SHA-1/SHA-256, and true random number generation autonomously without CPU involvement, offloading security tasks from the application layer. This SoC integration allows engineers to build a complete Linux-capable product with a minimal external bill of materials. Typical applications include industrial human-machine interfaces (HMIs) with capacitive touch and TFT LCD, building automation gateways, smart energy metering and substation controllers, IoT edge nodes running Linux, medical device controllers, and point-of-sale terminals. The 289-LFBGA package enables compact board layouts while supporting wide memory bandwidth. Designers should pay close attention to PCB layout: the 0.8 mm BGA pitch requires laser-via or microvia PCB technology, and the DDR interface needs matched-length routing and reference-voltage decoupling.

The 0.8 mm ball-pitch TFBGA package keeps PCB design manageable, and the integrated DDR2 dramatically lowers EMI, complexity and active power. Typical applications include industrial HMI panels, home and building automation gateways, point-of-sale terminals, smart energy meters, connected appliances, medical user-interface consoles, and ruggedized IoT edge nodes. The compact SiP footprint, low-power architecture, and rich Linux BSP support make it well suited for systems where a traditional discrete CPU + external DDR layout would push PCB size, EMI or BoM cost out of budget. When designing with this device, allocate the four-layer PCB stack for the 0.8 mm-pitch BGA fanout, route the DDR2 signals on inner layers with controlled impedance, and follow the Microchip SAMA5D2 hardware design checklist for power-rail decoupling and boot-mode strapping. The integrated PMIC companion (MIC2800 or equivalent from the Microchip reference design) simplifies sequencing and is recommended for production designs.

ATSAMA5D27C-D1G-CUR - 500MHz Cortex-A5 MPU 1Gbit DDR2 SiP | Microchip

The Microchip Technology ATSAMA5D27C-D1G-CUR is a high-performance, low-power ARM Cortex-A5 microprocessor unit (MPU) running up to 500 MHz, integrating 1 Gbit of DDR2 SDRAM in a System-in-Package (SiP) configuration. Housed in a 289-ball TFBGA (14x14 mm, 0.8 mm pitch), this SAMA5D2 series SoC combines a single Cortex-A5 core with 32 KB I-cache and 32 KB D-cache, NEON media engine, and a rich peripheral set including EMAC, USB, CAN-FD, FLEXCOM, ISI, SSC, and a Peripheral Touch Controller. An ARM Cortex-A5 based MPU (Microprocessor Unit) is a 32-bit application-class processor core implementing the ARMv7-A architecture, typically paired with a memory management unit (MMU) and used in embedded Linux and real-time operating system designs. Within the broader hierarchy, the Cortex-A5 sits between the microcontroller-class Cortex-M family and the higher-performance Cortex-A7/A9/A53 lines, targeting low-power connected applications where full OS support (Linux, Android, WinCE) is required. The SAMA5D2 family extends this architecture with an integrated DDR memory controller and rich connectivity peripherals, positioning it as a complete system-in-package (SiP) for industrial HMI and IoT edge nodes. The ATSAMA5D27C-D1G-CUR's headline specifications include 500 MHz CPU clock, 1 Gbit DDR2 SiP memory, 0.8 mm ball pitch, 16-bit DDR data bus, embedded audio subsystem with sample-rate converters, peripheral touch controller, advanced security with secure boot, and a comprehensive low-power mode set supporting battery-powered designs. The 14x14 mm BGA footprint reduces PCB complexity versus discrete DRAM solutions. Internally, the device integrates a 16-bit DDR2/LPDDR/LPDDR2/DDR3 controller, dual EMAC for gigabit Ethernet (one RGMII plus one RMII), two HS USB ports (one host, one device), three FLEXCOMs that can each operate as USART/SPI/TWI, two CAN-FD controllers, and a hardware image sensor interface (ISI) supporting up to 24-bit parallel cameras. Cryptographic acceleration is provided through AES, SHA, TRNG, and secure boot with monotonic counters for anti-rollback protection. Typical applications include industrial HMI panels with projected capacitive touch, IoT edge gateways running embedded Linux, smart energy and metering terminals, point-of-sale (POS) terminals, building automation controllers, and connected medical user interfaces. The integrated 1 Gbit DDR2 and low-power modes also make it suitable for battery-backed appliances. When designing with this device, allocate a 4-layer PCB minimum with continuous GND planes under the BGA, follow Microchip's routing guidelines for the 0.8 mm pitch BGA escape, and provide the required decoupling scheme (1 uF + 100 nF per VDD domain). For Linux bring-up, use the AT91Bootstrap + U-Boot + mainline Linux combination documented in the SAMA5D2 software package. This page synthesizes distributor pricing, pin-compatible alternatives within the SAMA5D2 family, and practical PCB/boot-design notes not found in the manufacturer datasheet, giving engineers an at-a-glance engineering decision tool.

ATSAMA5D27C-D5M-CU

ATSAMA5D27C-D5M-CU - 500MHz Cortex-A5 MPU, 512Mb DDR2 SiP | Microchip

The Microchip Technology ATSAMA5D27C-D5M-CU is a 500 MHz ARM Cortex-A5 microprocessor unit (MPU) that integrates 512 Mbit of DDR2 SDRAM inside a 289-ball LFBGA System-in-Package (SiP), measuring 14x14 mm with a 0.8 mm ball pitch. The SiP approach places the DRAM die directly on the package substrate, eliminating the need for an external DDR2 companion chip and removing PCB trace-matching concerns between the CPU and memory. 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.
