MCIMX502CVK8B - i.MX50 ARM Cortex-A8 MPU 800MHz | NXP
料号： MCIMX502CVK8B ✗ 停产MCIMX502CVK8B 概述
An applications processor is a system-on-chip (SoC) that integrates a CPU core, memory interfaces, peripheral controllers, and graphics or display logic into one die. Within the NXP i.MX portfolio, the i.MX50 sits below the i.MX6 family and above legacy ARM9 i.MX devices, offering Cortex-A8 performance for portable, human-machine-interface products rather than the higher-tier multimedia platforms. Its hierarchical position is: application processor -> microprocessor unit (MPU) -> SoC -> integrated circuit -> semiconductor device.
Key differentiating features include the ARM Cortex-A8 core with NEON media engine, hardware-accelerated LCD controller supporting up to XGA resolution, integrated power management, and a wide peripheral set (UART, SPI, I²C, USB, SD/MMC, NAND/NOR flash controllers). The device is designed for commercial temperature ranges and supports DDR2/LPDDR1 memory, making it well suited to cost-sensitive embedded designs.
From a system-architecture perspective, the i.MX50 uses a single Cortex-A8 core with NEON SIMD and a hardware L1/L2 cache hierarchy. Compared with i.MX28 (ARM9) predecessors, the Cortex-A8 core delivers substantially higher performance per MHz and adds the NEON engine for multimedia processing, while the integrated display pipeline removes the need for an external graphics controller.
Typical applications include DECT/IP phones, vending-machine displays, e-readers, portable medical devices, industrial HMI terminals, and home automation panels. The integrated LCD controller makes it particularly attractive for products requiring a graphical user interface without an external graphics chip.
When designing with this part, allocate PCB area for the 416-ball MAPBGA (0.5 mm or 0.8 mm pitch - verify with the manufacturer package drawing), use a 4-layer or higher PCB stack-up, and follow NXP's reference layout for power-decoupling and DDR routing. Boot-mode strapping pins must be configured through external pull resistors.

典型应用
MCIMX502CVK8B 适用于 7 应用s: DECT and IP Phones, Vending Machine Displays, Portable Medical Devices, E-Readers and Portable HMI, Industrial HMI Terminals, Home Automation Panels, Smart Appliance Displays.
DECT and IP Phones
The MCIMX502CVK8B's 800 MHz ARM Cortex-A8 core, NEON engine, and integrated LCD controller make it well suited to drive the graphical displays and audio pipelines of DECT and IP phones. Designers benefit from a single-chip solution that handles call control, voice DSP, and the LCD UI without an external graphics controller, keeping BOM cost low. Typical designs place the i.MX50 with DDR2, a small NAND flash, an audio codec (such as an NXP SGTL5000) on I²S, and a 4-5" TFT panel on the integrated LCD bus, achieving responsive UI performance at moderate power.
推荐
Vending Machine Displays
Vending and ticketing machines require a cost-optimized MPU capable of driving a graphical touchscreen and running networking stacks for telemetry or payment. The MCIMX502CVK8B's integrated LCD controller (up to XGA) and DDR2/LPDDR1 memory interface provide display and connectivity headroom at a commercial-grade price point. A typical 7" panel + capacitive touch + Ethernet-via-USB-Ethernet reference design fits within the i.MX50's peripheral set, while Linux Yocto BSP simplifies integration of payment and inventory-management software stacks.
推荐
Portable Medical Devices
Portable patient-monitoring and diagnostic devices need an MPU that balances compute, low power, and a display interface. The MCIMX502CVK8B's 800 MHz Cortex-A8 with NEON accelerates signal-processing algorithms (filtering, FFT) on patient waveforms, while the integrated LCD controller drives bedside displays without a separate GPU chip. Commercial temperature grade suits clinical-environment deployments, and the i.MX50 Linux BSP supports IEC 62304 software-lifecycle workflows that medical OEMs commonly adopt.
推荐
E-Readers and Portable HMI
E-readers and other portable HMI terminals benefit from the MCIMX502CVK8B's combination of ARM Cortex-A8 processing, NEON media acceleration, and integrated LCD controller. The chip's low BOM (one SoC + DDR2 + flash) supports slim industrial designs, while Linux support enables PDF rendering engines and e-paper panel drivers. Compared with ARM9-based i.MX28 designs, the Cortex-A8 delivers noticeably faster page-refresh performance and smoother UI transitions.
推荐
Industrial HMI Terminals
Industrial HMI panels - for factory automation, building controls, and kiosk terminals - leverage the MCIMX502CVK8B's display integration and rich peripheral set (UART for PLC links, SPI for sensors, USB for peripherals, Ethernet via external PHY). The 416-MAPBGA supports 4-layer PCB designs typical of industrial enclosures, and the i.MX50 software ecosystem accelerates development of Qt-based graphical interfaces that operators rely on for machine status visualization.
推荐
Home Automation Panels
Touchscreen home-automation control panels need an MPU that can drive a graphical UI, run networking stacks (Wi-Fi/Bluetooth via companion modules), and respond to user input in real time. The MCIMX502CVK8B provides Cortex-A8 performance and an integrated LCD controller at a consumer-friendly price, while Linux support enables Matter, Zigbee, or Z-Wave gateway bridging. Its commercial temperature grade and low BOM make it ideal for in-wall touch panels controlling lighting, HVAC, and security subsystems.
推荐
Smart Appliance Displays
Smart appliances (refrigerators, ovens, washers) increasingly integrate touchscreen panels for control and diagnostics. The MCIMX502CVK8B's integrated LCD controller, NEON engine, and commercial temperature rating meet the cost and reliability targets of consumer appliance OEMs. A typical reference design uses the i.MX50 with a 7-10" TFT, DDR2 memory, and Wi-Fi/BLE module, running a Linux-based UI stack that supports remote monitoring via mobile apps.

设计说明
The 416-MAPBGA (13 mm × 13 mm) requires a 4-layer or higher PCB stack-up with controlled-impedance routing for DDR2 traces. Follow NXP's i.MX50 hardware-design guide for via-in-pad recommendations, escape routing topology, and power/ground via stitching. Use 0.5 mm pitch escape rules and verify BGA land pattern against the manufacturer package drawing before fab.
Decoupling: place 0.1 µF X7R ceramic capacitors within 2 mm of every power pin pair on the i.MX50, plus bulk 10-47 µF tantalum or polymer capacitors on each supply rail. The ARM Cortex-A8 core rail requires bulk capacitance sized for worst-case dynamic load steps; insufficient bulk decoupling causes voltage droop and intermittent reset under heavy graphics activity.
Boot-mode strapping pins (BOOT_MODE, BOOT_CFG) must be configured via external pull resistors - leaving them floating causes boot failures. Verify boot-source selection (NAND, NOR, SD, USB serial) against the latest i.MX50 reference manual revision, since boot-pin mapping may differ between early silicon revisions and current mask sets.
DDR2 routing: length-match the data/address/control traces within the tolerances specified in the i.MX50 hardware-design guide (typically ±25 mils for data, ±50 mils for address/control). Use a 100 Ω differential impedance for clock and maintain reference-plane continuity under the entire DDR2 routing region to avoid signal-integrity issues.
