NXP Semiconductors MCIMX6U4AVM08ABR

Overview

MCIMX6U4AVM08ABR from NXP Semiconductors is an automotive-grade i.MX 6DualLite applications processor featuring dual Arm® Cortex®-A9 cores (64-bit DDR), 800 MHz operation, GPU-based 2D graphics acceleration, MLB interface support, and no VPU or EPDC. It targets infotainment head units requiring real-time HMI rendering, multi-source audio routing, and CAN-based vehicle network integration.

For engineers reviewing the MCIMX6U4AVM08ABR datasheet, MCIMX6U4AVM08ABR pinout, MCIMX6U4AVM08ABR application, or MCIMX6U4AVM08ABR equivalent, key selection criteria include its dual-core A9 architecture with TrustZone, automotive temperature range (−40°C to +125°C), MAPBGA-224 (21 × 21 mm, 0.8 mm pitch) package, integrated ASRC and ESAI for multichannel audio, and dual FlexCAN interfaces at 1 Mbps.

Technical Context

The MCIMX6U4AVM08ABR implements a symmetric dual-core Arm Cortex-A9 MPCore platform with 32 KB L1 instruction and data caches per core, shared 512 KB L2 cache, and NEON MPE co-processor. Its memory subsystem supports 16/32/64-bit DDR3/DDR3L/LPDDR2-800 with interleaving mode enabled for dual-channel LPDDR2-800.

It integrates dedicated multimedia accelerators including GPU3Dv5 (OpenGL ES 2.0), GPU2Dv2 (BitBlt), ASRC (10-channel asynchronous sample rate conversion), and IPUv3H (image processing), while omitting the VPU and EPDC blocks present in higher-tier variants like MCIMX6U6A. Security is enforced via Arm TrustZone, CAAM (16 KB secure RAM), SNVS, and A-HAB v4 boot authentication.

FAQ

What is the maximum operating frequency of the MCIMX6U4AVM08ABR?

The MCIMX6U4AVM08ABR operates at up to 800 MHz. When a 24 MHz crystal is used for USB functionality-as required by the design-the maximum achievable SoC speed is limited to 792 MHz per the i.MX 6Solo/6DualLite Electrical Characteristics specification (IMX6SDLAEC Rev. 9, Section 4.1). This constraint applies regardless of ambient temperature or voltage margin.

Does the MCIMX6U4AVM08ABR include a Video Processing Unit (VPU)?

No, the MCIMX6U4AVM08ABR does not include a Video Processing Unit. As confirmed in Table 1 of the IMX6SDLAEC datasheet, the "4" in the part number suffix indicates GPU and MLB support but excludes both VPU and EPDC. For hardware-accelerated 1080p video decode, engineers must select MCIMX6U6AVM08AB or MCIMX6U6AVM10AC instead.

What package type and ball count does the MCIMX6U4AVM08ABR use?

The MCIMX6U4AVM08ABR uses a 224-ball MAPBGA package measuring 21 mm × 21 mm with 0.8 mm pitch, as specified in Section 6.2 ("21x21 mm Package Information") of IMX6SDLAEC Rev. 9. This package is identical across all automotive-grade i.MX 6DualLite variants listed in Table 1, ensuring PCB layout compatibility within the family.

Which automotive serial interfaces are supported by the MCIMX6U4AVM08ABR?

The MCIMX6U4AVM08ABR supports two FlexCAN 2.0B controllers (1 Mbps each), an MLB150/50 interface for MOST networks, ESAI for multichannel audio transport, and ASRC for cross-domain sample rate conversion. These interfaces are explicitly enabled in the "Options" column for MCIMX6U4AVM08AB in Table 1 and detailed in Sections 1.2 and 3 of IMX6SDLAEC Rev. 9.

Is the MCIMX6U4AVM08ABR qualified for automotive temperature ranges?

Yes, the MCIMX6U4AVM08ABR is rated for the automotive temperature grade (−40°C to +125°C junction temperature), as indicated by the "A" in its part number nomenclature (Figure 1, IMX6SDLAEC Rev. 9) and confirmed in Table 1. This qualification covers operation under sustained thermal stress typical of under-dash installations and meets AEC-Q100 requirements per NXP's automotive product definition.
