MCIMX31LVKN5B

Microprocessors Overview

The MCIMX31LVKN5B is a multimedia application processor based on the ARM1136JF-S core, operating at up to 532 MHz. It features a 90 nm process with advanced power management including DVFS and power gating. The device includes an MPEG-4 hardware encoder, Image Processing Unit (IPU), Vector Floating Point co-processor, and extensive connectivity interfaces such as USB OTG, SDHC, and ATA. Unlike the standard MCIMX31, this variant lacks a Graphics Processing Unit (GPU). It utilizes a 457-ball MAPBGA package.

Microprocessors Feature Summary

• Multimedia acceleration via MPEG-4 hardware encoding and autonomous image processing

• Integrated security features including secure JTAG and random number generator
• Extensive peripheral connectivity supporting multiple memory and communication standards

Microprocessors Applications

• High-tier smartphone platforms
• Portable media players and mobile gaming devices
• Personal digital assistants (PDAs) and Wireless PDAs
• Digital cameras and portable DVD players

Microprocessors Procurement Notes

Verify silicon revision compatibility during procurement. The ordering suffix 'B' indicates Silicon Revision 1.2. Confirm that the specific mask set aligns with your design requirements regarding output buffer characteristics and PLL restrictions. Ensure the absence of the GPU in the L-series part matches your graphical interface needs before finalizing orders.

Microprocessors Selection Notes

Select this component for applications requiring high-performance multimedia processing without dedicated graphics acceleration. The L-series designation confirms the exclusion of the GPU block. Consider the 90 nm technology node and its associated power characteristics against modern alternatives. Verify that the required I/O voltages and memory interfaces are supported by the system architecture.

Microprocessors Part Context

This part belongs to the i.MX31 family of multimedia application processors from NXP (formerly Freescale). The 'L' suffix distinguishes it from the standard MCIMX31 by omitting the GPU. The 'B' suffix denotes Silicon Revision 1.2, which may have specific errata or electrical characteristic updates compared to earlier revisions like 1.15 or later revisions like 2.0.
