Product details

Overview

MCIMX31CVMN4DR2 from NXP Semiconductors (formerly Freescale) is an industrial- and automotive-grade multimedia applications processor built around the ARM1136JF-S core operating at 400 MHz. It integrates MPEG-4 hardware encoder (VGA @ 30 fps), Vector Floating Point (VFP11) co-processor, Autonomous Image Processing Unit (IPU), and SDMA controller. Designed for infotainment and human-machine interface systems in extended temperature environments (–40°C to +85°C), it supports DDR, NAND Flash, USB 2.0 OTG, SDHC, and ATA interfaces.

For engineers reviewing the MCIMX31CVMN4DR2 datasheet, MCIMX31CVMN4DR2 pinout, MCIMX31CVMN4DR2 application, or MCIMX31CVMN4DR2 equivalent, key selection considerations include its 473-ball MAPBGA package (19 × 19 mm, 0.8 mm pitch), dual-Vt 90 nm process, DVFS-capable power management, and absence of integrated GPU - distinguishing it from non-L variants and confirming its role as a cost-optimized, graphics-light multimedia SoC for deterministic embedded control.

Technical Context

The MCIMX31CVMN4DR2 implements the ARM v6 architecture with an 8-stage pipeline, Jazelle® Java acceleration, SIMD DSP extensions, and integrated MMUs with micro-TLBs backed by unified main TLBs. Its memory subsystem includes 16 KB instruction and 16 KB data L1 caches, 128 KB unified L2 cache, 32 KB ROM, and 16 KB SRAM - all accessible via high-speed AMBA L2 interface and optimized for low-latency interrupt handling and cache-coherent peripheral access.

Power management is implemented through multiple clock/power domains, independent gating, dynamic voltage and frequency scaling (DVFS), and state retention mode (QVCC = 0.95 V). The chip-level electrical specification mandates core supply (QVCC/QVCC1/QVCC4) between 1.22 V–1.47 V at 400 MHz, I/O supplies (NVCCx) from 1.75 V–3.1 V, and strict thermal limits: max junction temperature 105°C, RθJA = 29°C/W on 4-layer board.

Key Specifications

Parameter	Value and Actual Design Meaning
Core Architecture	ARM1136JF-S, ARM v6, 8-stage pipeline with Jazelle and SIMD support - enables real-time Java bytecode execution and efficient media processing without host CPU overhead.
Clock Speed	400 MHz maximum ARM core frequency - delivers deterministic performance for VGA-resolution video encoding and real-time audio streaming in resource-constrained systems.
MPEG-4 Encoder	Hardware-accelerated encode up to VGA @ 30 fps - offloads CPU, reduces system memory bandwidth, and enables low-power viewfinder operation without ARM involvement.
Memory Interfaces	DDR, SDRAM, NAND Flash, NOR Flash, SRAM, PSRAM - supports boot-from-NAND, multi-bank memory mapping, and flexible external storage for automotive HMI firmware and media assets.
Package	MAPBGA-473, 19 × 19 mm, 0.8 mm pitch, RoHS-compliant (Case 1931, MSL 3) - ensures mechanical stability in automotive vibration environments and compatibility with standard PCB assembly processes.
Operating Temperature	–40°C to +85°C ambient - qualified for under-dash automotive infotainment and industrial panel PCs requiring extended thermal reliability without derating.
Power Management	DVFS, power gating, clock gating, state retention (0.95 V core) - enables sub-100 µA deep-sleep current and rapid wake-up for always-on UI responsiveness in battery-backed systems.

Pinout & Package

MCIMX31CVMN4DR2 is housed in a 473-ball MAPBGA package (Case 1931), 19 mm × 19 mm, 0.8 mm ball pitch, RoHS-compliant and moisture-sensitive level 3 (MSL 3). Ball assignment follows Freescale's documented pinout for MCIMX31C silicon revision 2.0.1, with dedicated power/ground banks, configurable I/O banks supporting 1.8 V/2.5 V/3.3 V signaling, and differential clock inputs (CKIL/CKIH).

Pin/Terminal	Circuit Role	Design Meaning
CKIL / CKIH	Low-/High-frequency reference clock inputs	CKIL (32.768 kHz) clocks RTC/watchdog; CKIH (15–75 MHz) feeds DPLLs - critical for boot sequence, DVFS table validity, and timing-critical peripherals like USB OTG.
QVCC / QVCC1 / QVCC4	Core voltage supply pins (ARM/L2/cache)	Must be regulated within 1.22–1.47 V; offset ≤15 mV between rails - violation causes USB HS data corruption and L2 cache instability.
NVCC1–NVCC10	I/O voltage supply pins (grouped by function)	NVCC6/NVCC9 must be tied together; NVCC2/21/22 reserved for DDR only (1.75–1.95 V) - mismatch risks I/O latch-up or signal integrity failure.
GPIO1_5 / GPIO1_6	Dedicated power-ready and tamper-detect inputs	GPIO1_5 is input-only (pull-up required if unused); GPIO1_6 enables irreversible tamper detection - used for secure boot enforcement in automotive telematics.
USBOTG_D+ / USBOTG_D−	USB 2.0 OTG differential data pair	Requires 90 Ω differential impedance and on-die termination - enables host/device mode switching without external transceiver for compact infotainment docking solutions.

Key Features

Feature	Design Value
MPEG-4 Hardware Encoder	Real-time VGA @ 30 fps encoding with on-the-fly post-processing - eliminates need for external codec IC and reduces BOM cost in rear-seat entertainment systems.
Autonomous Image Processing Unit (IPU)	Hardware-accelerated camera interface, blending, rotation, and display path control - enables zero-CPU-load viewfinder, overlay compositing, and dual-display output for instrument cluster + center stack.
Vector Floating Point (VFP11) Co-processor	Tightly coupled ARM v6 FPU supporting 3D graphics math and audio FFTs - accelerates navigation map rendering and voice recognition algorithms without floating-point emulation overhead.
Smart DMA (SDMA) Controller	26-channel programmable DMA with peripheral-to-peripheral transfers - relieves ARM core from audio streaming, sensor data acquisition, and display buffer updates in real-time HMI applications.
Security Subsystem (RNGA, SCC, RTIC)	FIPS-140 compliant random number generator, secure RAM, and runtime integrity checkers - provides cryptographic key generation and boot authentication for OEM firmware protection in connected vehicles.

FAQ

What is the silicon revision and key functional difference of MCIMX31CVMN4DR2?

The MCIMX31CVMN4DR2 is silicon revision 2.0.1, which includes an updated iROM enabling boot from USB High-Speed and SD/MMC - a critical enhancement over revision 2.0 for field-upgradable automotive systems. This revision also resolves errata ENGcm02610 related to USB HS data corruption at low core voltages, ensuring robust high-speed peripheral operation across the full 1.22–1.47 V QVCC range.

Does MCIMX31CVMN4DR2 include a graphics processing unit (GPU)?

No, MCIMX31CVMN4DR2 does not include an integrated GPU. The MCIMX31C series includes GPU functionality only in non-L variants; the "C" suffix denotes the base multimedia processor without GPU, while "LC" explicitly indicates GPU removal. MCIMX31CVMN4DR2 relies on its Vector Floating Point (VFP11) co-processor and IPU for 2D/3D acceleration - sufficient for UI rendering and video overlays but not for complex 3D gaming or OpenGL ES workloads.

What are the mandatory power supply sequencing requirements for MCIMX31CVMN4DR2?

MCIMX31CVMN4DR2 requires strict power-up sequencing: QVCC (core) must stabilize before NVCC (I/O) rails, and all QVCC rails (QVCC/QVCC1/QVCC4) must remain within ±15 mV of each other during operation. Failure to meet this causes USB HS transfer errors and L2 cache corruption. Power-down sequencing is less restrictive but recommends disabling PLLs before core voltage ramp-down to prevent clock domain metastability.

Can MCIMX31CVMN4DR2 support dual-display output simultaneously?

Yes, MCIMX31CVMN4DR2 supports dual-display output via its integrated Image Processing Unit (IPU), which provides two independent display paths - one for LCD/TFT and another for TV encoder (NTSC/PAL). The IPU handles blending, rotation, and scaling in hardware, allowing concurrent rendering of instrument cluster graphics and infotainment UI without ARM CPU intervention or external compositor IC.

What security features are implemented in MCIMX31CVMN4DR2 for automotive use cases?

MCIMX31CVMN4DR2 integrates three hardware security blocks: RNGA (FIPS-140 compliant random number generator), SCC (Security Controller with Secure RAM for key storage), and RTIC (Run-Time Integrity Checker for peripheral register validation). These enable secure boot, cryptographic key generation, tamper detection (via GPIO1_6), and runtime firmware integrity verification - meeting foundational requirements for ISO/SAE 21434-compliant automotive telematics and gateway modules.
