NXP Semiconductors MCIMX31LDVMN5DR2

Overview

MCIMX31LDVMN5DR2 from NXP Semiconductors (formerly Freescale) is a multimedia applications processor based on the ARM1136JF-S core, operating up to 532 MHz with integrated SDMA controller, MPEG-4 hardware encoder (VGA@30 fps), Vector Floating Point (VFP11) co-processor, and Image Processing Unit (IPU). It targets portable media players and mid-tier smartphones requiring low-power, high-performance video encoding and real-time image processing.

For engineers reviewing the MCIMX31LDVMN5DR2 datasheet, MCIMX31LDVMN5DR2 pinout, MCIMX31LDVMN5DR2 application, or MCIMX31LDVMN5DR2 equivalent, key selection criteria include its 19×19 mm MAPBGA-473 package, –20°C to +70°C industrial temperature range, absence of GPU (MCIMX31L variant), dual-Vt 90 nm process, and support for DDR, NAND Flash, USB 2.0 OTG, SDHC, and I²C peripherals.

Technical Context

The MCIMX31LDVMN5DR2 implements the ARM v6 architecture with an eight-stage pipeline, Jazelle® Java acceleration, SIMD DSP instructions, and MMU-backed TLBs. Its memory subsystem includes 16 KB instruction and 16 KB data L1 caches, a 128 KB unified L2 cache, 32 KB ROM, and 16 KB SRAM - all optimized for low-latency multimedia streaming and secure boot via ROMPATCH.

Power management relies on Dynamic Voltage and Frequency Scaling (DVFS), multiple clock/power domains, and fine-grained clock gating. The device integrates dedicated hardware accelerators: MPEG-4 encoder (VGA@30 fps), autonomous IPU for on-the-fly video preprocessing, and SDMA for offloading bulk memory-to-peripheral transfers - reducing ARM CPU intervention in display, camera, and audio paths.

FAQ

What is the maximum operating frequency of the MCIMX31LDVMN5DR2 and under what conditions?

The MCIMX31LDVMN5DR2 operates up to 532 MHz in overdrive mode with core voltage between 1.47 V and 1.65 V. At non-overdrive conditions (1.22–1.38 V), the maximum frequency is 400 MHz. Duty cycle restrictions apply above 1.52 V to limit cumulative overdrive time to ≤10,950 hours over product lifetime - verified per Freescale Errata ENGcm02610.

Does the MCIMX31LDVMN5DR2 include a graphics processing unit (GPU)?

No, the MCIMX31LDVMN5DR2 is part of the MCIMX31L series, which explicitly excludes the GPU present in the base MCIMX31. This is confirmed in the Freescale MCIMX31_5 datasheet Rev. 4.3, Section 1: "The MCIMX31L does not include a graphics processing unit (GPU)." All other multimedia features - MPEG-4 encoder, IPU, VFP11 - remain fully functional.

What package type and ball count does the MCIMX31LDVMN5DR2 use?

The MCIMX31LDVMN5DR2 uses a 19×19 mm MAPBGA package with 473 balls (Case 1931), 0.8 mm pitch, RoHS-compliant and MSL Level 3. This matches the "DVMN" suffix in the part number and is documented in Table 1 (Ordering Information) and Section "Package Information and Pinout" (pages 103–114) of the MCIMX31_5 datasheet Rev. 4.3.

How does the Image Processing Unit (IPU) in the MCIMX31LDVMN5DR2 reduce system memory bandwidth?

The IPU in MCIMX31LDVMN5DR2 performs on-the-fly video preprocessing - including rotation, blending, color-space conversion, and viewfinder generation - without involving the ARM CPU or external memory. This eliminates intermediate frame buffering in SDRAM, directly reducing memory bandwidth demand by up to 40% and lowering system power consumption during camera/display operations.

What security features are integrated into the MCIMX31LDVMN5DR2 for trusted execution?

The MCIMX31LDVMN5DR2 integrates RNGA (FIPS-140 compliant random number generator), SCC (Security Controller with Secure RAM), and RTIC (Run-Time Integrity Checker). These modules enable secure boot, cryptographic key storage, runtime memory integrity verification, and tamper detection - all required for DRM, secure firmware updates, and HIPAA/PCI-DSS compliant applications.
