MCIMX31CJMN4D

The MCIMX31CJMN4D is a single-core 32-bit application processor based on the ARM1136JF-S core running at 400 MHz, optimized for embedded and industrial applications. It combines a compact 473-LFBGA (19x19) package with integrated multimedia acceleration, DDR memory interfaces and a range of peripheral controllers to support user interfaces, media processing and secure embedded designs.

Key Features

• Core  ARM1136JF-S single-core 32-bit processor operating at 400 MHz, providing deterministic embedded processing performance.
• Multimedia and Co-processors  Integrated multimedia engines including GPU, Image Processing Unit (IPU), MPEG-4 hardware encoder (VGA, 30 fps referenced in product documentation) and Vector Floating Point (VFP) support for media and signal-processing tasks.
• Memory  DDR memory controller support for external system memory.
• Interfaces  Multiple high-speed and control interfaces with USB 2.0 support (listed as USB 2.0 (3)), ATA, MMC/SDIO and CompactFlash connectivity options; display and user-input controllers for LCD, keyboard and keypad; additional 1-Wire interface.
• Security  On-chip security features including Random Number Generator, RTIC, Secure Fusebox, Secure JTAG and Secure Memory to support protected boot and secure storage functions.
• Power and Low-Power Modes  Architecture-level power saving techniques called out in documentation (DVFS, power gating, clock gating) to optimize performance-per-watt for embedded systems.
• Package and Mounting  473-LFBGA surface-mount package, 19×19 mm body size for high-density board layouts.
• Operating Range and Qualification  Industrial qualification with an operating temperature range of −40 °C to 85 °C and RoHS compliance.

Typical Applications

• Industrial Human-Machine Interfaces  Drives LCD displays, keypad and keyboard inputs and handles multimedia required for operator panels and control terminals.
• Multimedia Embedded Devices  Leverages on-chip MPEG-4 encoder, GPU and IPU to enable video capture/processing and graphical user interfaces at VGA-class resolutions.
• Embedded Connectivity Gateways  USB 2.0 ports, MMC/SDIO and storage interfaces support data transfer and peripheral expansion in embedded communication modules.

Unique Advantages

• Integrated multimedia accelerators: GPU, IPU and MPEG-4 encoder reduce external component count and offload media workloads from the CPU core.
• Security building blocks included: Multiple on-chip security features help implement secure boot and protect sensitive data without additional external hardware.
• Embedded-focused I/O mix: Native support for LCD, keyboard/keypad, USB 2.0 and storage interfaces simplifies designs for user-interface and data-logging applications.
• Industrial temperature capability: −40 °C to 85 °C operating range and industrial qualification make the device suitable for extended-temperature embedded deployments.
• Power optimization features: Documented DVFS, power gating and clock gating techniques enable designers to tune power consumption for battery- or thermally-constrained systems.
