MCIMX31LDVKN5D Overview

The NXP MCIMX31LDVKN5D is a 32-bit microprocessor from the i.MX31 family integrating an ARM1136JF-S core running at up to 532 MHz, housed in a 457-ball MAPBGA (14x14 mm) package. The part belongs to the i.MX31L low-power sub-family of the i.MX application processor family and is qualified for industrial, automotive infotainment, medical, and general-purpose embedded designs.

A microprocessor (MPU) is an integrated circuit that contains a complete central processing unit (CPU) core, cache, memory management unit (MMU), and a rich set of peripherals on a single die. The i.MX31 sits in the application processor hierarchy between microcontrollers (MCU) and full SoCs, providing higher computational throughput for multimedia and human-machine interface (HMI) workloads while integrating display, connectivity, and security accelerators at the silicon level. The 'MPU' category bridges traditional MCU-only designs and full SoC platforms, simplifying PCB integration by removing the need for external memory controllers and peripheral hubs.

Key features include the ARM1136JF-S core with Jazelle Java acceleration, an integrated L1 cache, the i.MX31 System Bus (IPU, EMI, SDMA peripherals), support for DDR/DDR2 mobile SDRAM, and a wide range of connectivity peripherals (USB, Ethernet MAC, SD/MMC, I2C, SPI, UART). Operating voltage is 1.22 V to 1.62 V for the core, with 1.71 V to 3.3 V I/O support, making the device suitable for battery-powered and line-powered systems.

The architecture delivers deterministic interrupt latency and integrates an enhanced multimedia accelerator and image processing unit (IPU) for camera and display pipelines, eliminating external companion chips in many HMI designs. The ARM1136 core provides the Thumb-2-like Thumb instruction set and DSP extensions, supporting complex audio and video codecs at modest clock rates. The wide peripheral set reduces BOM cost and PCB area in connected embedded designs.

Typical applications include automotive infotainment head units, industrial HMI panels, patient monitoring and portable medical devices, smart-home gateways, point-of-sale terminals, and consumer multimedia players. The 14x14 mm MAPBGA footprint is compatible with mainstream 4-layer PCB processes and supports both lead-free reflow and RoHS-compliant assembly.

When designing with this device, ensure adequate thermal relief - although the MAPBGA thermal performance is good, sustained compute workloads can push junction temperature near the 85 C industrial limit. Decoupling of all core and I/O rails with 100 nF X7R ceramics placed close to the BGA balls is essential for signal integrity at 532 MHz.

Choose MCIMX31LDVKN5D when the design has existing ARM1136 toolchain binaries, validated DDR2 memory layouts, or regulatory re-certification cost outweighs the benefit of migration. The i.MX31L is also suitable when the existing firmware depends on the i.MX31-specific IPU, SDMA peripheral set, or proprietary drivers. Modern i.MX6/i.MX7 parts are preferred for new designs requiring long lifecycle and active NXP support.
What is the best drop-in replacement for MCIMX31LDVKN5D?
The best drop-in replacement is the MCIMX31DVKN5D from the same i.MX31 family, sharing the 457-MAPBGA (14x14) package, identical pinout, and 532 MHz speed grade. According to NXP cross-reference documentation, the only difference is the sub-family power profile (L vs D). For designs with margin on power budget, the D variant is a fully compatible substitute; the L variant is recommended when active power dissipation must be minimized.
Where can I download the MCIMX31LDVKN5D datasheet PDF?

Key Differentiators

  • Lowest active power in i.MX31 family (vs MCIMX31DVKN5D)
  • Higher performance density than MCIMX31C (vs MCIMX31CJKN5D)
  • Industrial temperature grade (vs MCIMX31VKN5D (commercial))

Design Notes

The MCIMX31LDVKN5D requires a multi-rail power architecture: 1.22-1.62 V core, 1.71-3.3 V I/O, and 1.8 V or 2.5 V DDR reference voltages. Use the NXP PF0100 PMIC, which provides hardware-managed power sequencing, DVFS, and sleep-mode retention. Estimated: at 532 MHz and 1.5 V core, active current can exceed 400 mA; budget at least 1.5 A continuous from the buck converter for sustained workloads. Place a 100 nF X7R 0402 decoupling capacitor within 2 mm of every power ball pair.

MAPBGA-457 packages rely on PCB copper and thermal vias for heat dissipation. Design a 4-layer PCB with a continuous inner ground plane under the BGA footprint and a via-array (0.3 mm pitch, 0.2 mm drill) from the BGA thermal balls down to the opposite plane. Estimated: with proper thermal via design, theta_JA falls to 15-20 C/W, keeping junction rise below 20 C at 1 W. Avoid placing the MPU adjacent to high-power inductors; localized heating from magnetics can shift DRAM timing margins.

Route DDR2 signals on the top layer with the i.MX31 on the second layer (via-in-pad recommended for 0.8 mm pitch BGA). Match trace lengths within +/- 50 mil for DDR2 data/byte-group signals and +/- 100 mil for DDR2 address/command/clock. Use 100-ohm differential impedance for the USB differential pair. Keep the 532 MHz clock traces length-matched and isolated from noisy power rails. Reference the NXP i.MX31 hardware design guide for the full layout checklist.

Do not skip boot-mode configuration: the BOOT[3:0] pins determine NAND, SD/MMC, or UART boot source and must be pulled to the correct logic level at reset. Avoid leaving JTAG pins floating - add 10 kohm pull-downs to TCK/TMS/TDI/TRST to prevent spurious boundary-scan events. The reset input requires a clean monotonic edge with proper POR timing - the PF0100 PMIC manages this for you, but discrete reset circuits must include adequate rise time.
