MCIMX31LVMN5C - ARM1136JF-S SoC, 532MHz, 473-LFBGA | NXP / Freescale
N.º da peça: MCIMX31LVMN5C ✓ AtivoMCIMX31LVMN5C Visão geral
An applications processor is a system-on-chip (SoC) that integrates a microprocessor core, memory interfaces, display and connectivity peripherals, plus dedicated multimedia accelerators, into a single device. Within the broader taxonomy, the i.MX31 belongs to the applications processor family -> ARM-based SoC -> multimedia SoC -> semiconductor. The MCIMX31LVMN5C includes an Image Processing Unit (IPU), MPEG-4/H.263 hardware codec block, integrated LCD controller supporting up to SXGA resolution, and a rich set of system peripherals such as USB, MMC/SD, NAND flash and SDRAM controllers.
Key features of the MCIMX31LVMN5C include a high-bandwidth 64-bit system bus, Vector Floating Point (VFP) coprocessor, an integrated DDR1 memory controller supporting up to 133 MHz operation, and the Multi-Layer AHB system fabric to provide simultaneous peripheral and memory access. Hardware-accelerated MPEG-4 encoding and decoding enable smooth video playback while keeping CPU load low, and the IPU delivers 2D graphics without burdening the ARM core. The 473-LFBGA package exposes all advanced peripherals while keeping the PCB area below 19x19 mm.
The MCIMX31L architecture combines an ARM1136JF-S RISC core with on-chip cache, tightly-coupled memory, and an accelerator engine for image and video processing. Designers benefit from dedicated hardware blocks for video encoding and decoding, which offload compute-intensive tasks from the main CPU, leaving headroom for the operating system and application code. System-level integration is strong: external memory, storage and display buses are routed directly to the SoC, simplifying board design.
Typical applications for the MCIMX31LVMN5C include portable media players, smartphones and PDAs, industrial HMI terminals, point-of-sale terminals, automotive infotainment prototypes, and portable navigation devices. The combination of ARM1136 performance, hardware video codecs, and a compact BGA package makes the part a strong fit for battery-powered multimedia products.
When designing with this part, allocate sufficient PCB area for the 473-ball BGA fan-out and plan thermal relief through the exposed internal balls or board copper. Use the MCIMX31 SDK and the supplied BSDL/JTAG files to validate prototypes, and consult the i.MX31 reference manual for SDRAM timing closure. Note that this part has been in production for many years and lifecycle status should be confirmed at the time of order.

Aplicações típicas
MCIMX31LVMN5C é adequado para 7 aplicaçãos: Portable Media Players, Smartphones and PDAs, Industrial HMI Terminals, Point-of-Sale (POS) Terminals, Portable Navigation Devices (PND), Automotive Infotainment Prototypes, Medical Imaging and Patient Terminals.
Portable Media Players
The MCIMX31LVMN5C's hardware MPEG-4/H.263 encoder-decoder block, IPU-assisted 2D acceleration, and ARM1136JF-S running at 532 MHz make it a strong fit for PMPs that must decode SD video files while driving an LCD up to SXGA resolution. The i.MX31L variant omits the GPU, trimming both die cost and active power for battery-powered playback designs where software rendering of the UI overlay is sufficient. A typical PMP architecture pairs the SoC with DDR1 memory, a 3-inch to 4-inch LCD panel, NAND storage, and USB 2.0 for file transfer, all of which the MCIMX31LVMN5C connects to directly through its integrated controllers.
Recomendado
Smartphones and PDAs
For early-2000s smartphone and PDA reference designs, the MCIMX31LVMN5C offered the right blend of ARM1136JF-S performance, on-chip peripherals, and power profile. The integrated LCD controller, USB 2.0 On-The-Go, MMC/SD host, and camera interface let product teams fold display, storage, networking, and imaging onto a single SoC without expensive companion chips. Removing the GPU keeps the bill of materials low for feature phones that rely on simple 2D UI rendering, and the 473-LFBGA package keeps the device slim enough to fit behind a 2.4 to 3-inch panel.
Recomendado
Industrial HMI Terminals
Industrial HMI panels need a stable, long-lifecycle processor that can drive an SVGA or SXGA TFT for years without forced requalification - exactly the use case where the MCIMX31LVMN5C has lived for over a decade. The 532 MHz ARM1136JF-S executes embedded Linux, QNX, or WinCE with sufficient headroom for touch input, animations, and fieldbus protocol stacks, while hardware MPEG-4 decoding lets OEMs embed training videos in the same terminal. With no GPU, the i.MX31L delivers predictable thermal output in sealed enclosures without active cooling.
Recomendado
Point-of-Sale (POS) Terminals
POS terminals depend on reliable multimedia rendering (signature capture, video advertising, receipt graphics) and long product lifecycles in the field. The MCIMX31LVMN5C's hardware MPEG-4 codec accelerates promotional video, the integrated LCD controller drives 4.3-inch to 7-inch panels, and USB On-The-Go plus MMC/SD enable peripheral expansion. The i.MX31L's GPU-free design keeps cost reasonable for high-volume deployments and simplifies validation because no GPU driver changes are needed between firmware revisions.
Recomendado
Portable Navigation Devices (PND)
PNDs demand efficient multimedia playback, a strong ARM core for map-rendering and route algorithms, and tight power budgets. The MCIMX31LVMN5C combines a 532 MHz ARM1136JF-S CPU with the IPU handling 2D map acceleration, freeing the main core for routing and UI logic. Hardware MPEG-4 decoding offloads video-based guidance playback, while the integrated SDRAM and NAND controllers keep external component count and PCB area minimal.
Recomendado
Automotive Infotainment Prototypes
Engineering teams building automotive infotainment prototypes and aftermarket head units benefit from the MCIMX31LVMN5C's multimedia subsystem. Hardware video decoding, an SXGA-capable LCD controller, and multiple high-speed serial interfaces allow pre-production infotainment units to evaluate HMI layouts before specifying the production silicon. Although the i.MX31 family is not AEC-Q100 qualified, its widespread availability, stable BSPs, and clear pin-compatible upgrade paths to i.MX6 make it a productive prototype platform for automotive HMI development.
Recomendado
Medical Imaging and Patient Terminals
Medical imaging workstations and bedside patient terminals need powerful multimedia yet a stable, supportable hardware base. The MCIMX31LVMN5C drives bedside panels and imaging-friendly interfaces while hardware MPEG-4 support enables video-based training and telemedicine replay. Combined with regulated OS ports from partners, the part has supported long-life medical device families, and the i.MX31L's higher reliability comes from the smaller die (no GPU block) running cooler for longer in always-on wall-mounted enclosures.

Notas de projeto
The MCIMX31LVMN5C is housed in a 473-ball LFBGA on a 0.8 mm pitch, which requires PCB fabrication with microvia and laser-drilled via technology. Plan for at least a 1.6 mm finished board thickness and laser microvias in any inner escape layers; through-hole vias under the BGA often cause soldering defects at this fine pitch. Refer to IPC-7092 for BGA design and to the i.MX31 reference manual for the recommended ball-fanout stack-up before committing to fab.
The 473-LFBGA has a theta_JA around 25-30 C/W depending on PCB stack-up; at full 532 MHz load in sealed enclosures, the die can rise by 25-40 C above ambient. Pair the package with adequate copper flooding in the inner layers and thermal vias stitched beneath the central array to keep junction temperature below 105 C in consumer enclosures. Use the thermal resistance figures in the i.MX31 datasheet as the basis for your thermal budget.
Several SDRAM timing and signal-integrity pitfalls frequently bite first-time i.MX31 users: (1) DDR1 trace lengths must be matched within the DQS-to-DQ skew budget documented in the reference manual, (2) the boot-mode configuration pins determine boot source and are read at POR - sample carefully, (3) the SDRAM controller requires firmware init sequences that differ between Linux BSP versions. Use a known-good DDR1 timing calibration pattern before custom board bring-up.
Multi-layer AHB fabric traffic between the ARM1136JF-S, IPU, MPEG block, and peripherals can produce transient current spikes on the core supply. Decouple each power rail with at least one 0.1 µF ceramic near every supply pin pair plus bulk capacitance on the regulator, and keep the DDR1 reference-plane discontinuity below 0.5 dB to maintain a clean read/write margin. Series-termination resistors on high-speed nets clean edge rates if the demo board layout is reused.
Informações de conformidade
