MCIMX51LEVK - i.MX51 ARM Cortex-A8 MPU | NXP Semiconductors
MPN: MCIMX51LEVK ✗ End of LifeMCIMX51LEVK Overview
An applications processor (AP) is a system-on-chip class of microcontroller that integrates a high-performance CPU, memory controllers, hardware accelerators, and rich peripheral I/O into a single device. Within the hierarchy, an applications processor sits above ordinary microcontrollers (MCU) and below high-end CPUs/APUs; it targets workloads such as graphical user interfaces, video playback, and connected edge devices that need both processing throughput and a rich software ecosystem (typically Linux or Android).
Key feature highlights for the MCIMX51LEVK include the ARM Cortex-A8 CPU core, the legacy Freescale i.MX51 multimedia subsystem, on-chip L2 cache, and a comprehensive peripheral set covering display, camera, USB, Ethernet, and SD/MMC interfaces. The part targets industrial temperature grades and is suited to long-lifecycle designs where NXP's roadmap stability matters as much as raw performance.
Technically the i.MX51 family was one of the early ARM Cortex-A8 implementations at NXP, manufactured on a CMOS process and pairing the CPU with a vectoring floating-point unit, hardware video accelerators, and an enhanced memory controller. Rochester Electronics' continued stocking of this part confirms it is treated as a mature, long-life component suitable for production continuance programs.
Typical applications include industrial human-machine interface (HMI) panels, portable medical devices, point-of-sale terminals, smart-home gateways, and telematics/fleet management hardware. The integrated peripherals reduce BOM count for graphics- and connectivity-rich designs.
When designing with this part, engineers should verify software support longevity and confirm whether NXP's BSP for the specific i.MX51 sub-variant covers their Linux/Android kernel version. Long-life programs may need to engage distributors such as Rochester Electronics for sustained supply.
This page synthesizes distributor pricing, availability signals, and practical sourcing context that complement the manufacturer datasheet and help engineers evaluate the MCIMX51LEVK for new and legacy designs.

Typical Applications
MCIMX51LEVK is suitable for 6 applications: Industrial Human-Machine Interface (HMI) Panels, Point-of-Sale Terminals and Retail Kiosks, Portable Medical Devices and Patient Monitors, Telematics and Fleet-Management Hardware, Smart-Home Gateways and Home-Automation Hubs, Industrial IoT Edge Gateways.
Industrial Human-Machine Interface (HMI) Panels
The MCIMX51LEVK's integrated display controller, image sensor interface (for camera input), USB and Ethernet peripherals make it a single-chip host for industrial HMI panels. The ARM Cortex-A8 core provides sufficient headroom for Qt/Embedded-style UIs and graphical control loops at 800x480 to 1280x720 WVGA panel sizes. The i.MX51 family supports hardware-accelerated 2D blitting, offloading common UI primitives (alpha-blended cursors, color-keyed overlays, pixel-format conversions) from the CPU and leaving it free for application logic and fieldbus protocols such as Modbus or EtherCAT. Compared to discrete MPU + external LCD controller designs, the MCIMX51LEVK reduces BOM count, simplifies PCB layout, and offers deterministic display refresh without a dedicated timing controller IC.

Point-of-Sale Terminals and Retail Kiosks
Retail POS terminals require secure processing of payment data, rich graphical user interfaces, and reliable connectivity for peripherals (barcode scanners, receipt printers, cash drawers). The MCIMX51LEVK provides the ARM Cortex-A8 performance headroom to run embedded Linux running a payment application alongside a Qt-based UI, while the integrated Ethernet and USB host controllers cover printer/scanner connectivity. The on-chip hardware crypto accelerators within the i.MX51 family reduce main-CPU load during TLS/SSL handshake and PIN encryption, helping meet PCI PTS timing requirements without an external secure element. Pairing the MCIMX51LEVK with a discrete secure element IC and a tamper-detection module completes a typical retail POS architecture at lower BOM cost than x86-based designs.
Recommended
Portable Medical Devices and Patient Monitors
Portable medical devices such as patient monitors, infusion pumps, and handheld diagnostic tools require reliable embedded compute with long-life silicon supply. The MCIMX51LEVK runs an embedded OS (typically Linux with a real-time kernel) for waveform display, alarm logic, and data logging. The integrated LCD controller drives the operator panel, while the image sensor interface supports optional camera input (e.g. barcode reader for patient ID). The on-chip peripherals reduce total part count, an important consideration for IEC 60601-1 reliability targets and for keeping the bill of materials manageable. The part's mature status also makes it attractive for medical devices where re-validation cost discourages frequent silicon migration.
Recommended
Telematics and Fleet-Management Hardware
Vehicle telematics and fleet-management hardware aggregate GPS, accelerometer, CAN-bus, and cellular connectivity data into a single box mounted in commercial vehicles. The MCIMX51LEVK's Ethernet, USB, and SD/MMC peripherals provide the connectivity fabric, while the ARM Cortex-A8 handles protocol stacks and edge analytics. The on-chip display controller drives a local operator screen for driver-facing prompts, and CAN connectivity (via external PHY) integrates with vehicle bus systems. Compared to discrete MCU + external peripheral hubs, the MCIMX51LEVK reduces component count, lowers automotive-bus interface cost, and provides a single Linux image target across telematics and HMI subsystems.
Recommended
Smart-Home Gateways and Home-Automation Hubs
Smart-home gateways aggregate Zigbee, Z-Wave, Wi-Fi, and BLE radios into a single user-facing device controlled via touchscreen or voice. The MCIMX51LEVK handles the Linux-based OS and IoT protocol stacks (MQTT, Thread border router, Matter controller) while supporting a local touch UI for setup and control. The on-chip display and USB peripherals enable local touchscreen control, the Ethernet MAC connects to the home router, and the SD/MMC interface stores logs and firmware. Compared to MCU-class solutions, the Cortex-A8 headroom keeps the gateway responsive as the number of supported devices grows; compared to newer Cortex-A53 designs, the i.MX51 family's mature BSP makes it suitable for stable long-life gateways.
Recommended
Industrial IoT Edge Gateways
Industrial IoT edge gateways collect data from PLCs and sensors (Modbus, EtherCAT, Profinet, analog I/O) and forward filtered streams to cloud or on-prem servers. The MCIMX51LEVK runs a containerised edge stack with Docker/Kubernetes-lite, applying analytics locally to reduce uplink bandwidth. The on-chip Ethernet and USB peripherals connect to industrial networks and storage, the SD/MMC interface holds local buffer storage during uplink outages, and the hardware crypto engine secures TLS links. Compared to MCU-class edge nodes, the ARM Cortex-A8 class lets engineers run full Linux containers, choose from a wide range of open-source Industrial IoT frameworks, and reuse existing cloud-side libraries with minimal porting.

- Full NXP BSP / Linux support (vs Mature ARM9 legacy parts)
Design Notes
The MCIMX51LEVK requires multiple supply rails (core, DDR memory I/O, standard I/O, and analog). Use a multi-rail PMIC or discrete DC-DC converters with sequenced enable signals so that core voltage rises before I/O. Common NXP-recommended rails from the i.MX51 hardware design guide include a 1.2V core, 1.8V DDR PHY, and 3.3V I/O. Decouple each rail with 100nF X7R ceramic capacitors within 5 mm of the package balls and bulk polymer/electrolytic capacitors to handle transient current steps during display and camera activity.
At typical i.MX51-class operating points in enclosed enclosures (POS terminals, HMI panels), the MCIMX51LEVK dissipates a few watts under video and CPU load. NXP-recommended thermal design places a thermal pad or copper spreader directly under the BGA's central thermal balls with thermal vias to inner-layer planes. Keep junction temperature within the industrial-grade spec by derating clock speeds in software or applying fanless heatsink design for sealed enclosures.
Route DDR2/DDR3 memory traces as matched-length pairs (within 25 mil of each other) from the MPU to the DRAM, with reference planes on adjacent layers. For the BGA fanout use microvia stacks and keep signal vias clear of the thermal-ball array. The USB 2.0 differential pair (D+/D-) needs 90-ohm differential impedance with common-mode chokes; the Ethernet MII/RMII/HSIC traces need series-termination and length-matching as specified in the i.MX51 hardware design guide.
Always boot the part from a verified boot image and confirm the secure-boot fuses are configured for production before mass flash. Ensure the BOOT_MODE pins are pulled correctly at reset; i.MX51 boot configuration errors cause 'no console output' debug cycles. Do not hot-plug the SD card or USB during firmware update; use the i.MX51 watchdog to recover from brown-out conditions during the flash write sequence.
