FAQ

What is the maximum operating frequency of the MCIMX31CVMN4CR2?

The MCIMX31CVMN4CR2 operates at a maximum CPU frequency of 400 MHz using the ARM1136JF-S™ core. This speed is achievable under specified conditions: core supply QVCC/QVCC1/QVCC4 ≥ 1.22 V, ambient temperature ≤ 85°C, and proper thermal management. Frequency scaling is supported via DVFS to reduce power during low-load periods while maintaining real-time responsiveness.

Does the MCIMX31CVMN4CR2 include a graphics processing unit (GPU)?

Yes, the MCIMX31CVMN4CR2 includes an integrated Graphics Processing Unit (GPU) for hardware acceleration of 2D and 3D graphics algorithms. This GPU is part of the full i.MX31C feature set. Note that the MCIMX31LC variant excludes the GPU, but MCIMX31CVMN4CR2 is the C-series part and therefore includes it as confirmed in the official Freescale MCIMX31C/MCIMX31LC Technical Data Rev. 4.3 document.

What memory types does the MCIMX31CVMN4CR2 support directly?

The MCIMX31CVMN4CR2 supports DDR SDRAM, SDRAM, NOR Flash, NAND Flash, and SRAM directly through its External Memory Interface (EMI). It includes dedicated controllers for NAND Flash (NFC), enhanced SDRAM (ESDCTL), and wireless external interface (WEIM) for NOR/SRAM. DDR support is implemented via the EMI's DDR interface block, enabling high-bandwidth access for multimedia buffering and OS execution.

Is the MCIMX31CVMN4CR2 qualified for automotive applications?

Yes, the MCIMX31CVMN4CR2 is qualified for automotive applications with an operating temperature range of –40°C to +85°C and compliance with AEC-Q100 stress testing standards. Its design includes features critical for automotive use: tamper detection (GPIO1_6), secure boot via fusebox, RNGA for cryptographic key generation, and robust power sequencing requirements validated for vehicle electrical environments.

What is the package type and ball count of the MCIMX31CVMN4CR2?

The MCIMX31CVMN4CR2 uses a MAPBGA-473 package: 19 mm × 19 mm body size, 0.8 mm ball pitch, RoHS-compliant lead-free construction, and moisture sensitivity level (MSL) 3. This package is documented in Freescale's MCIMX31C/MCIMX31LC Technical Data Rev. 4.3 as Case 1931, with full pinout provided in Section 5 ("Package Information and Pinout") on page 99.
