MCIMX31LDVKN5DR2 Présentation
An applications processor (sometimes called an MPU - microprocessor unit) is a highly integrated SoC that combines one or more CPU cores with on-chip memory controllers, display/graphics engines, image-signal-processing blocks, and standard I/O. Applications processors sit at the top of the embedded silicon hierarchy alongside microcontrollers, but are distinguished by their higher CPU performance, MMU support for full operating systems (Linux, Windows Embedded), and dedicated multimedia accelerators. The i.MX31 specifically targets human-machine-interface applications where it must drive a display, run a rich OS, and handle streaming media simultaneously.
Key features of this part include a 532 MHz ARM1136JF-S core with Jazelle Java acceleration, an integrated LCD controller capable of driving QVGA and VGA panels, a CMOS image sensor interface for camera input, hardware-accelerated MPEG-4/H.263 encoding/decoding, USB 2.0 full-speed On-The-Go, and a memory controller that supports mDDR and SDRAM. The MAPBGA-457 14x14 mm package with 0.8 mm or 0.5 mm pitch is designed for high-density consumer PCB layouts and offers full JTAG/ETM debug access. The 'L' in the part number indicates the consumer-lite feature mix and the '5' speed grade denotes the 532 MHz core clock.
Typical applications include portable media players, in-vehicle infotainment head units, industrial human-machine interface panels, point-of-sale terminals, and medical patient-monitoring displays. The i.MX31 is particularly well suited to designs that require a Linux-capable CPU with built-in display and camera pipelines, eliminating the need for an external media co-processor. The 532 MHz speed grade balances computational throughput with power consumption for fanless embedded enclosures.
When designing with this MPU, allocate PCB space for the MAPBGA-457 footprint with microvia technology, route the DDR memory bus with controlled impedance, and provide decoupling for the multiple voltage domains (core, I/O, PLL). This page synthesizes distributor pricing, i.MX31 family variants, and practical design notes not found in the manufacturer datasheet.

Recommandé
Set-Top Box Auxiliary Processors
The MCIMX31LDVKN5DR2 is occasionally used as an auxiliary processor in IPTV set-top box designs, handling UI rendering and EPG navigation while the main SoC decodes H.264 video. Its hardware MPEG-4 decode makes it well suited for low-cost hybrid DVB-IP STBs, and the integrated LCD controller supports the front-panel VFD-style graphics without an additional microcontroller. The dual-SSI interface drives audio DACs with IEC 60958 compatibility. Designers should consider the i.MX6ULL for new STB designs as the i.MX31 family is EOL, but the existing PCB and software stack can keep this part in serviceable production.

Notes de conception
The 457-ball MAPBGA at 0.8 mm / 0.5 mm pitch requires microvia PCB technology (laser-drilled blind/buried vias). A minimum 4-layer stackup with continuous GND plane adjacent to the BGA is essential. Route the 32-bit DDR memory bus with matched-length traces (delta < 50 ps) to maintain signal integrity at 133 MHz. Decouple the multiple voltage domains (Vcore, VDDIO, PLL_AVDD, USB_AVDD) with 100 nF X7R capacitors within 2 mm of each ball. Follow the NXP i.MX31 hardware design guide for escape routing.
Estimated: at 532 MHz with full peripheral activity, the i.MX31 dissipates approximately 1.0-1.4 W. The MAPBGA-457 has a theta_JA of roughly 20-25 C/W on a 4-layer JEDEC test board, yielding junction temperature rise of 20-35 C above ambient. For sealed enclosures without airflow, derate the maximum ambient to 55 C or add a thermal via array under the BGA thermal balls. Always measure Theta_JC in your specific board stackup for accurate thermal characterization; do not rely on datasheet typical numbers without verification.
Do not assume the i.MX31 part numbering implies all features - the 'L', 'C', 'D' suffixes represent distinct peripheral mixes. Designing in the 'L' (Consumer Lite) feature mix and then realizing you need MPEG-4 encoding or the second camera interface can force a respin. Verify your datasheet revision against the specific 'N5' speed bin in your BOM. Also note that the i.MX31 family is EOL - obsolete parts do not get silicon revision updates, so lot-to-lot variation is the only variation to manage.
Use series termination resistors (22-33 ohm) on the SDRAM clock, SDRAM address/command, and SDRAM data strobe lines when length matching allows. The CMOS sensor interface can be sensitive to impedance discontinuities - keep it on the top layer and avoid vias. The USB 2.0 FS data lines require 90-ohm differential impedance with matched-length traces. Add a common-mode choke on D+/D- for EMI compliance per EN 55022 / FCC Part 15.
