NXP Semiconductors MCIMX351AJQ5C

Overview

MCIMX351AJQ5C from NXP Semiconductors (formerly Freescale) is an AEC-Q100 Grade 3 qualified automotive application processor based on the ARM1136JF-S core operating at 532 MHz, featuring 16 KB L1 instruction cache, 16 KB L1 data cache, 128 KB L2 cache, and integrated image processing unit (IPU) for real-time video preprocessing and display control in infotainment head units.

For engineers reviewing the MCIMX351AJQ5C datasheet, MCIMX351AJQ5C pinout, MCIMX351AJQ5C application, or MCIMX351AJQ5C equivalent, key selection considerations include its 532 MHz CPU frequency, -40°C to +85°C ambient rating, MAPBGA-5284 (17 × 17 mm, 0.8 mm pitch) package, dual CAN interfaces, USB 2.0 OTG with internal HS PHY, and absence of OpenVG GPU and PATA support per i.MX35 family documentation.

Technical Context

The MCIMX351AJQ5C implements the ARM1136JF-S core (r1p3) with Jazelle Java acceleration, VFP11 co-processor, and eight-stage pipeline with branch prediction. Its AP domain integrates a 128 KB L2 cache, MMU, and IPUv1 for camera sensor interface (up to 30 Mpixels/s), color space conversion, and display controller functions.

Power management leverages clock gating, power gating, and well biasing to reduce leakage-enabling operation at 1.22 V core voltage. The shared domain includes SDMA engine, EMI supporting mobile DDR/DDR2/SDRAM, and peripheral interconnect via SPBA and AIPS buses, with silicon revision 2.1 requiring distinct ball map (Table 95/Table 97) incompatible with revision 2.0 layouts.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MCIMX351AJQ5C?

The MCIMX351AJQ5C 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 derating.

Does the MCIMX351AJQ5C include an OpenVG-compatible graphics processing unit?

No, the MCIMX351AJQ5C does not include an OpenVG 1.1 GPU. As explicitly stated in Section 1.1 and Table 2 of the datasheet, OpenVG graphics acceleration is unavailable for the MCIMX351 variant-only MCIMX353, MCIMX355, MCIMX356, and MCIMX357 support this feature.

Is the MCIMX351AJQ5C qualified for automotive use?

Yes, the MCIMX351AJQ5C is AEC-Q100 Grade 3 qualified and rated for ambient operating temperatures from -40°C to +85°C, making it suitable for automotive infotainment and navigation applications installed in passenger compartments.

What package type and ball count does the MCIMX351AJQ5C use?

The MCIMX351AJQ5C uses a MAPBGA package designated Case 5284, measuring 17 × 17 mm with 0.8 mm pitch and 361 signal balls. Its silicon revision 2.1 ball map (Table 95/Table 97) is incompatible with revision 2.0 layouts, requiring strict adherence to the correct footprint.

Which external memory types are supported by the MCIMX351AJQ5C?

The MCIMX351AJQ5C supports mobile DDR, DDR2 (4-bank architecture), SDRAM (up to 133 MHz), SLC/MLC NAND Flash, NOR Flash, and SRAM via its External Memory Interface (EMI), as detailed in Section 1 and Table 4 of the MCIMX35SR2AEC datasheet.
