MCIMX31CJMN4DR2

The MCIMX31CJMN4DR2 is an NXP Semiconductors i.MX31 series multimedia application microprocessor based on the ARM1136JF-S core. It is a single‑core, 32‑bit MPU running at 400 MHz and integrates multimedia co‑processors and peripheral controllers to support embedded multimedia and human‑interface designs.

Designed for demanding embedded and industrial applications, the device emphasizes performance with low power consumption and on‑chip integration that simplifies system design for navigation/infotainment and industrial control scenarios.

Key Features

• Core — ARM1136JF-S single 32‑bit core operating at 400 MHz, delivering deterministic processing suitable for embedded multimedia workloads.
• Memory — Integrated DDR memory controller support for external system memory.
• Multimedia and Co‑processors — Includes GPU, Image Processing Unit (IPU), MPEG‑4 hardware encoder and Vector Floating Point (VFP) co‑processor to accelerate video and image processing tasks.
• Interfaces — USB 2.0 support as specified; multiple peripheral interfaces for media and user‑interface connectivity.
• Security — On‑chip security features including Random Number Generator, RTIC, Secure Fusebox, Secure JTAG and Secure Memory to protect keys and secure boot elements.
• Low‑power design — Architecture and silicon optimized for reduced power consumption using techniques such as DVFS, power gating and clock gating (as described in the series technical documentation).
• Package and Mounting — 473‑LFBGA (19 × 19 mm, 0.8 mm pitch) surface‑mount package supplied in Tape & Reel (TR) format for assembly.
• Qualification and Temperature Range — Industrial qualification with an operating temperature range of −40 °C to 85 °C.

Typical Applications

• Automotive infotainment and navigation — Multimedia processing and display control for in‑vehicle systems and navigation interfaces.
• Industrial control (human interface) — HMI and operator panel applications that require multimedia handling and responsive user interfaces within industrial temperature ranges.
• Embedded multimedia devices — Devices that require integrated video encoding, image processing and graphics acceleration in a compact package.

Unique Advantages

• Highly integrated multimedia engine: On‑chip GPU, IPU and MPEG‑4 encoder reduce external component count and simplify BOM for multimedia systems.
• Security features built in: RNG, secure fusebox, secure JTAG and secure memory provide hardware primitives to protect firmware and sensitive data.
• Industrial temperature rating: −40 °C to 85 °C operation and industrial qualification enable deployment in temperature‑sensitive embedded applications.
• Power‑aware architecture: Design techniques such as DVFS, power gating and clock gating support optimized power consumption for battery or thermally constrained systems.
• Compact, production‑ready package: 473‑LFBGA in Tape & Reel simplifies automated assembly and saves PCB area for dense embedded designs.
