NXP Semiconductors MCIMX351AJQ5CR2

Overview

MCIMX351AJQ5CR2 from NXP Semiconductors (formerly Freescale) is an AEC-Q100 Grade 3 automotive application processor based on the ARM1136JF-S core operating at 532 MHz, featuring 16 KB L1 instruction and data caches, 128 KB L2 cache, integrated Image Processing Unit (IPU), dual CAN interfaces, and support for mobile DDR/DDR2/SDRAM memory. It targets infotainment head units requiring real-time video decode, audio processing, and graphical UI rendering in ambient temperatures up to 85 °C.

For engineers reviewing the MCIMX351AJQ5CR2 datasheet, MCIMX351AJQ5CR2 pinout, MCIMX351AJQ5CR2 application, or MCIMX351AJQ5CR2 equivalent, key selection considerations include its AEC-Q100 qualification, 532 MHz CPU frequency, IPU-accelerated camera/display pipeline, dual CAN bus support, and absence of OpenVG GPU and PATA interface compared to higher-tier i.MX35 variants.

Technical Context

The MCIMX351AJQ5CR2 implements the ARM1136JF-S core (r1p3) with Jazelle Java acceleration, VFP11 floating-point co-processor, and eight-stage pipeline with branch prediction. Its AP domain integrates 128 KB on-chip SRAM and a multiported crossbar switch for concurrent peripheral access.

Power management leverages clock gating, power gating, and well biasing to reduce leakage-enabling operation at 1.22 V internal logic voltage. The shared domain includes Smart DMA (SDMA) with 32 channels, External Memory Interface (EMI) supporting SDR/DDR2/mobile DDR, and asynchronous sample rate converter (ASRC) for audio resampling with –120 dB THD+N.

Key Specifications

Pinout & Package

MCIMX351AJQ5CR2 uses a 1568-ball MAPBGA package (Case 5284), 17 mm × 17 mm, 0.8 mm pitch, RoHS-compliant, MSL Level 3. Ball map corresponds to silicon revision 2.1 (Table 95/97); layout incompatible with revision 2.0.

FAQ

What is the maximum operating frequency of the MCIMX351AJQ5CR2?

The MCIMX351AJQ5CR2 operates at a maximum frequency of 532 MHz, as confirmed in Table 1 of the MCIMX35SR2AEC datasheet (Rev. 10). This speed rating applies to silicon revision 2.1 and meets all specifications of the 400 MHz variant, allowing drop-in replacement in existing 400 MHz designs without timing revalidation.

Does the MCIMX351AJQ5CR2 include an OpenVG graphics accelerator?

No, the MCIMX351AJQ5CR2 does not include an OpenVG 1.1 graphics processing unit (GPU). As explicitly stated in Section 1.1 and Table 2 of the MCIMX35SR2AEC datasheet, the GPU is unavailable for the MCIMX351 variant; it is present only in MCIMX355 and MCIMX356 derivatives.

Is the MCIMX351AJQ5CR2 qualified for automotive use?

Yes, the MCIMX351AJQ5CR2 is AEC-Q100 Grade 3 qualified, rated for ambient operating temperatures from –40 °C to +85 °C. This qualification is documented in the Introduction section of the MCIMX35SR2AEC datasheet and verified through standardized stress testing per JEDEC JESD22-A108.

What memory types does the MCIMX351AJQ5CR2 support?

The MCIMX351AJQ5CR2 supports mobile DDR, DDR2 (4-bank architecture), and SDRAM up to 133 MHz via its External Memory Interface (EMI). It also interfaces with SLC/MLC NAND Flash, NOR Flash, and SRAM, as specified in Section 1 and Table 4 of the MCIMX35SR2AEC datasheet.

Does the MCIMX351AJQ5CR2 support Parallel ATA (PATA) interface?

No, the MCIMX351AJQ5CR2 does not support Parallel ATA (PATA). According to Table 2 in the MCIMX35SR2AEC datasheet, PATA is marked "-" for MCIMX351, and Section 1.1 explicitly states that PATA is not available for this variant-unlike MCIMX356 which includes it.
