NXP Semiconductors MCIMX31DVMN5D

Overview

MCIMX31DVMN5D from NXP Semiconductors (formerly Freescale) is an ARM1136JF-S-based multimedia applications processor targeting portable media players and mid-tier smartphones. It operates at up to 532 MHz, integrates a 128 KB L2 cache, MPEG-4 hardware encoder (VGA@30 fps), Vector Floating Point (VFP11) co-processor, and supports DDR, NAND Flash, and SDIO interfaces.

For engineers reviewing the MCIMX31DVMN5D datasheet, MCIMX31DVMN5D pinout, MCIMX31DVMN5D application, or MCIMX31DVMN5D equivalent, key selection criteria include thermal resistance (RθJA = 46°C/W, 19×19 mm package), core voltage range (1.22–1.65 V), operating temperature (–20°C to +70°C), and GPU availability - confirmed present in MCIMX31DVMN5D (unlike MCIMX31L variants).

Technical Context

The MCIMX31DVMN5D implements the ARM1136JF-S core with eight-stage pipeline, Jazelle® Java acceleration, and SIMD DSP instructions. Its memory system includes 16 KB instruction and 16 KB data L1 caches, plus a 128 KB unified L2 cache - all backed by AMBA L2 interface and non-blocking data cache architecture.

Power management relies on Dynamic Voltage and Frequency Scaling (DVFS), multiple clock/power domains, and independent power gating. The chip integrates dedicated modules including Image Processing Unit (IPU), Smart DMA (SDMA), USB 2.0 OTG, three CSPI interfaces, and security accelerators (RNGA, SCC, RTIC) - all accessible via the AIPS bus fabric.

Key Specifications

Pinout & Package

MCIMX31DVMN5D uses a 473-ball MAPBGA package (Case 1931, 19 × 19 mm, 0.8 mm pitch) with RoHS-compliant lead-free finish and MSL Level 3 moisture sensitivity rating. Ball map follows JEDEC MO-270AB standard with defined power, ground, I/O, and differential signal groupings.

FAQ

Does MCIMX31DVMN5D include a graphics processing unit (GPU)?

Yes, MCIMX31DVMN5D includes an integrated GPU for hardware acceleration of 2D and 3D graphics algorithms. This distinguishes it from the MCIMX31L variant, which omits the GPU. The GPU is documented in the MCIMX31 block diagram and Module Inventory table, and is enabled in the standard MCIMX31 silicon mask M91E used in MCIMX31DVMN5D.

What is the maximum operating frequency of MCIMX31DVMN5D and under what conditions?

MCIMX31DVMN5D supports up to 532 MHz in overdrive mode with core voltage between 1.47 V and 1.65 V. Non-overdrive operation is rated up to 400 MHz at 1.22–1.38 V. Duty cycle restrictions apply for overdrive use: cumulative operation must not exceed 10,950 hours (1.25 years) to maintain reliability, per the MCIMX31 Technical Data Rev. 4.3 specification.

Which package type and ball count does MCIMX31DVMN5D use?

MCIMX31DVMN5D uses a 473-ball MAPBGA package (Case 1931), measuring 19 × 19 mm with 0.8 mm pitch. This is explicitly listed in Table 1 (Ordering Information) of the MCIMX31 Technical Data document, distinguishing it from the 457-ball 14 × 14 mm variant used in other MCIMX31 part numbers like MCIMX31DVKN5D.

Does MCIMX31DVMN5D support hardware-accelerated MPEG-4 video encoding?

Yes, MCIMX31DVMN5D includes a dedicated MPEG-4 hardware encoder capable of real-time VGA resolution video encoding at 30 fps. This capability is confirmed in Section 1.1 "Features" and the Functional Description chapter of the MCIMX31 Technical Data, and applies to all MCIMX31 variants including MCIMX31DVMN5D.

What are the thermal resistance characteristics of MCIMX31DVMN5D in its native package?

MCIMX31DVMN5D in the 19 × 19 mm MAPBGA package has a junction-to-ambient thermal resistance (RθJA) of 46°C/W under natural convection on a single-layer board, and 29°C/W on a four-layer board. These values are specified in Table 7 of the MCIMX31 Technical Data Rev. 4.3 and directly inform heatsink and PCB layout requirements for sustained 532 MHz operation.
