MCIMX31LCVMN4CR2

The MCIMX31LCVMN4CR2 is an i.MX31-series multimedia applications microprocessor from NXP Semiconductors, featuring a single ARM1136JF-S 32‑bit core clocked at 400 MHz. It targets industrial and embedded multimedia systems that require integrated processing, multimedia acceleration, and extended temperature operation.

Built for low-power, high-performance multimedia tasks, the device integrates DDR memory controllers, dedicated multimedia engines including an IPU and an MPEG‑4 hardware encoder, and a suite of security features—packaged in a 473‑LFBGA (19 × 19 mm) surface‑mount package qualified for industrial use.

Key Features

• Processor Core — ARM1136JF‑S single 32‑bit core @ 400 MHz for deterministic embedded processing.
• Memory Support — Integrated DDR memory controller to interface with external SDRAM types for system memory and buffering.
• Multimedia & Image Processing — Autonomous Image Processing Unit (IPU) and a hardware MPEG‑4 encoder (VGA, 30 fps) for accelerated video and image tasks.
• Co‑processors — Vector Floating Point (VFP) and multimedia DSP acceleration to offload compute‑intensive audio/video and signal operations.
• Interfaces — Multiple USB 2.0 interfaces (USB 2.0 (3)) and display/key input controllers (keyboard, keypad, LCD) to support common peripheral connectivity.
• Security & Debug — On‑chip Random Number Generator, RTIC, Secure Fusebox, Secure JTAG and Secure Memory features to support platform security implementations.
• Low‑power Technologies — Architecture optimized for power savings using DVFS, power gating and clock gating; implemented in 90 nm technology with dual‑Vt transistors (as documented for the series).
• Package & Assembly — 473‑LFBGA (19 × 19 mm, 0.8 mm pitch) in Tape & Reel (TR) format, surface mount for automated PCB assembly.
• Industrial Temperature Range — Rated for operation from −40 °C to 85 °C and specified as Industrial qualification.

Typical Applications

• Industrial Human‑Machine Interfaces (HMI) — Drive displays, key input and image processing in control panels and operator interfaces using onboard IPU and display controllers.
• Embedded Multimedia Appliances — Enable video encode/playback and media handling with the MPEG‑4 encoder and multimedia co‑processors.
• Embedded Connectivity Platforms — Support USB 2.0 peripherals and host/device topologies for data transfer and peripheral integration.

Unique Advantages

• Balanced Performance and Power: 400 MHz ARM1136JF‑S core combined with DVFS and power‑gating techniques reduces system power without sacrificing real‑time responsiveness.
• Integrated Multimedia Engines: On‑chip IPU and MPEG‑4 hardware encoder accelerate video and image tasks, reducing the need for external accelerators.
• Security Primitives Onboard: Hardware RNG, secure fusebox and secure JTAG support system protection and secure boot/design strategies.
• Industrial‑Grade Operation: Specified for −40 °C to 85 °C operation and listed with Industrial qualification to match embedded deployment requirements.
• Compact, Assembly‑Ready Package: 473‑LFBGA in Tape & Reel supports compact board layouts and high‑volume surface‑mount manufacturing.
