MCIMX31CJMN4DR2

Microprocessors Overview

The MCIMX31CJMN4DR2 is an automotive-grade multimedia application processor from NXP, based on the ARM1136JF-S core running at 400 MHz. It features a 90 nm process with DVFS and power gating for low-power operation. The device includes a GPU, MPEG-4 hardware encoder, Image Processing Unit (IPU), and Vector Floating Point co-processor. Memory resources comprise 16 KB L1 instruction cache, 16 KB L1 data cache, 128 KB L2 unified cache, 32 KB ROM, and 16 KB SRAM. Operating voltage ranges from 1.22 V to 1.47 V for the core and 1.75 V to 3.1 V for I/O. It supports interfaces including USB 2.0 OTG, SDHC, ATA, PCMCIA, UART, SPI, I2C, and 1-Wire. The package is MAPBGA-473 (Case 1931) with a 19x19 mm footprint.

Microprocessors Procurement Notes

Verify that the specific part number corresponds to Silicon Revision 2.0.1, which updates iROM to support boot from USB HS and SD/MMC. Confirm the suffix indicates the correct tape-and-reel packaging variant if required by assembly equipment. Ensure compatibility with automotive qualification standards as specified in the datasheet electrical characteristics section.

Microprocessors Selection Notes

Select this component when automotive environmental ratings are mandatory alongside high-performance multimedia processing. The inclusion of a dedicated GPU distinguishes it from the MCIMX31LC variant. Consider the 400 MHz ARM1136JF-S performance envelope relative to system power constraints enabled by DVFS. Verify peripheral interface requirements against the available module inventory such as SDHC, ATA, and USB OTG.
