NXP Semiconductors MCIMX31LCVMN4DR2

Overview

MCIMX31LCVMN4DR2 from NXP Semiconductors (formerly Freescale) is a multimedia applications processor based on the ARM1136JF-S core, operating at 400 MHz with 16 KB instruction and 16 KB data L1 caches, 128 KB unified L2 cache, and integrated SDMA controller. It lacks a GPU but includes MPEG-4 hardware encoder (VGA @ 30 fps), Vector Floating Point (VFP11) co-processor, and Image Processing Unit (IPU), targeting automotive infotainment and industrial human-interface systems.

For engineers reviewing the MCIMX31LCVMN4DR2 datasheet, MCIMX31LCVMN4DR2 pinout, MCIMX31LCVMN4DR2 application, or MCIMX31LCVMN4DR2 equivalent, key selection criteria include its –40°C to +85°C industrial temperature rating, 19 × 19 mm MAPBGA-473 package with 0.8 mm pitch, dual-Vt 90 nm process, DVFS support, and absence of GPU versus full MCIMX31C variants.

Technical Context

The MCIMX31LCVMN4DR2 implements the ARM v6 architecture with Jazelle® Java acceleration, Thumb® instruction set, and SIMD DSP extensions. Its memory subsystem integrates 32 KB ROM for boot code, 16 KB SRAM for low-power audio streaming, and supports DDR, NAND Flash, NOR Flash, SDRAM, and SRAM via the External Memory Interface (EMI).

Power management relies on dynamic voltage and frequency scaling (DVFS), independent clock and power domain gating, and state retention mode with 0.95 V core supply. The chip includes three USB controllers (2 Host + 1 OTG), dual SDHC interfaces, three I²C buses, three CSPI modules, five UARTs, and dedicated security modules (RNGA, SCC, RTIC, SJC) compliant with AEC-Q100 and FIPS-140 requirements.

FAQ

What is the maximum operating frequency of the MCIMX31LCVMN4DR2?

The MCIMX31LCVMN4DR2 operates at a maximum CPU frequency of 400 MHz using the ARM1136JF-S core. This speed is achieved with proper core voltage (1.22–1.47 V) and stable 26 MHz CKIH reference clock. Frequency scaling is supported via DVFS, but operation above 400 MHz is not specified or guaranteed for this silicon revision.

Does the MCIMX31LCVMN4DR2 include a graphics processing unit (GPU)?

No, the MCIMX31LCVMN4DR2 does not include a GPU. Per Freescale documentation, the "L" suffix denotes the GPU-less variant of the i.MX31 family. Graphics acceleration relies solely on the Vector Floating Point (VFP11) co-processor and Image Processing Unit (IPU); dedicated 2D/3D rendering hardware is absent in MCIMX31LCVMN4DR2.

What package type and pin count does the MCIMX31LCVMN4DR2 use?

The MCIMX31LCVMN4DR2 uses a 19 × 19 mm MAPBGA package with 473 solder balls and 0.8 mm pitch (Case 1931). It is RoHS-compliant, lead-free, and rated MSL Level 3. Pin assignments match the MCIMX31CVMN4DR2, enabling PCB layout reuse where GPU functionality is not required.

Which memory types are supported by the MCIMX31LCVMN4DR2's External Memory Interface (EMI)?

The MCIMX31LCVMN4DR2 supports DDR SDRAM, NAND Flash, NOR Flash, PSRAM, SDRAM, and SRAM via its integrated External Memory Interface (EMI). The EMI includes dedicated controllers for NAND (NFC), enhanced SDRAM (ESDCTL), and a multi-master memory interface (M3IF), enabling flexible memory subsystem design for boot, code execution, and data storage.

What security features are integrated into the MCIMX31LCVMN4DR2?

The MCIMX31LCVMN4DR2 integrates RNGA (FIPS-140 compliant random number generator), SCC (Security Controller with Secure RAM), RTIC (Run-Time Integrity Checker for boot authentication), and SJC (Secure JTAG Controller). These modules enable secure boot, cryptographic key protection, tamper detection via GPIO1_6, and debug lockdown - meeting AEC-Q100 and industrial security requirements.
