Product details
Overview
MCIMX6U4AVM08AC from NXP Semiconductors (formerly Freescale) is an automotive-grade i.MX 6DualLite applications processor featuring dual ARM Cortex-A9 cores running at 800 MHz, integrated 2D graphics acceleration (GPU2Dv2), MediaLB (MLB) interface, and no Video Processing Unit (VPU) or EPDC. It supports DDR3/LVDDR3/LPDDR2-800 memory, two FlexCAN interfaces, and HDMI 1.4 output - deployed in automotive instrument clusters and infotainment head units.
For engineers reviewing the MCIMX6U4AVM08AC datasheet, MCIMX6U4AVM08AC pinout, MCIMX6U4AVM08AC application, or MCIMX6U4AVM08AC equivalent, key selection criteria include confirmed absence of VPU hardware, MLB interface support for MOST networks, automotive temperature grade (−40°C to +125°C), 21×21 mm MAPBGA package with 0.8 mm pitch, and dual-core Cortex-A9 execution with TrustZone security.
Technical Context
The MCIMX6U4AVM08AC implements a symmetric dual-core ARM Cortex-A9 MPCore platform with 32 KB L1 instruction and data caches per core, 512 KB shared L2 cache, and NEON MPE co-processor. It integrates dedicated hardware accelerators including GPU2Dv2 (BitBlt), ASRC (asynchronous sample rate converter), and CAAM (cryptographic acceleration module with 16 KB secure RAM).
Its system architecture includes four uSDHC ports supporting UHS-I SDR-104 (104 MB/s), dual MIPI CSI-2 camera interfaces (up to 1 Gbps/lane), HDMI 1.4 transmitter, LVDS display controller, and two FlexCAN 2.0B controllers operating at 1 Mbps - all compliant with automotive functional safety requirements and AEC-Q100 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Dual ARM Cortex-A9 @ 800 MHz - enables concurrent real-time HMI rendering and background telematics processing without OS-level scheduling bottlenecks. |
| Graphics Acceleration | GPU2Dv2 (BitBlt) only - provides hardware-accelerated 2D UI composition but excludes 3D OpenGL ES 2.0 or video decode capabilities. |
| Memory Interface | 64-bit DDR3/LVDDR3/LPDDR2-800 - delivers up to 6.4 GB/s peak bandwidth for multi-display buffer handling and high-resolution graphics layering. |

| Temperature Range | −40°C to +125°C junction - qualified for under-hood and dashboard-mounted automotive applications per AEC-Q100 Grade 2. |
Pinout & Package
MCIMX6U4AVM08AC uses a 21 mm × 21 mm MAPBGA package with 484 balls and 0.8 mm pitch (Freescale BGA Case 2240). Pin assignments follow the standardized i.MX 6 signal naming convention defined in IMX6SDLAEC Rev. 5, with ball map documented in Section 6.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_ARM | Core Power Supply | 1.2 V ±3% supply for dual Cortex-A9 cores and L1/L2 cache - requires low-noise regulation and local decoupling per IMX6SDLAEC Section 4.2. |
| ENET_RX_CLK | Ethernet Receive Clock | 25 MHz differential input for IEEE 802.3 100BASE-TX - routed with controlled impedance (100 Ω differential) to minimize jitter-induced frame loss. |
| CAN1_TX | FlexCAN1 Transmit | CMOS output driving external CAN transceiver (e.g., TJA1042) - supports 1 Mbps bit rate with slew-rate control enabled per IMX6SDLAEC Table 4-37. |
| MLB_CLK | MediaLB Clock Input | 25 MHz single-ended reference clock for MLB150 physical layer - must meet ±50 ppm stability and <1 ps RMS jitter per MOST specification compliance. |
| HDMI_HPD | HDMI Hot Plug Detect | Open-drain active-low signal indicating display connection status - pulled up externally to 3.3 V and monitored by IOMUXC to trigger EDID read sequence. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX6U6AVM08AC | Includes VPU and GPU3Dv5 - adds 1080p H.264 decode and OpenGL ES 2.0 3D rendering. | Required for applications needing video playback or 3D GUI (e.g., 3D navigation maps). | Select when VPU-assisted video decode or GPU3D-accelerated UI is mandatory; otherwise MCIMX6U4AVM08AC reduces BOM cost and power consumption. |
| MCIMX6S4AVM08AC | Single-core Cortex-A9 (800 MHz), same GPU2Dv2/MLB feature set, lower DDR width (32-bit). | Suitable for cost-sensitive entry-level clusters with single-display output and reduced memory bandwidth needs. | Choose for simpler HMI designs where dual-core processing headroom is unnecessary; retains identical peripheral compatibility and software stack. |
Compared with MCIMX6U6AVM08AC, the MCIMX6U4AVM08AC removes VPU hardware to reduce die size and thermal envelope while retaining full MLB, CAN, and 2D graphics capability - making it optimal for non-video automotive HMIs. Against MCIMX6S4AVM08AC, it doubles CPU throughput and memory bandwidth for multi-tasking clusters without increasing software porting effort.

FAQ
Does MCIMX6U4AVM08AC include a Video Processing Unit (VPU)?
No, MCIMX6U4AVM08AC explicitly omits the VPU hardware block. This is confirmed in Table 1 of the IMX6SDLAEC datasheet, which lists "no VPU" for this part number variant. The absence of VPU means MCIMX6U4AVM08AC does not support hardware-accelerated video decode (e.g., H.264, MPEG-4) or encode functions - video processing must be handled in software or via external silicon.
What is the maximum DDR3 memory bandwidth supported by MCIMX6U4AVM08AC?
MCIMX6U4AVM08AC supports a 64-bit DDR3/LVDDR3/LPDDR2-800 interface, delivering a theoretical peak bandwidth of 6.4 GB/s. This is validated in Section 1.2 of IMX6SDLAEC, where the DualLite configuration is specified with 64-bit DDR support - enabling high-throughput frame buffer access for dual-display automotive HMIs.
Is MCIMX6U4AVM08AC pin-compatible with MCIMX6U6AVM08AC?
Yes, MCIMX6U4AVM08AC and MCIMX6U6AVM08AC share identical 21×21 mm MAPBGA packages, ball count (484), pitch (0.8 mm), and signal-to-ball mapping per IMX6SDLAEC Section 6.2. They differ only in internal silicon configuration (VPU presence), allowing PCB reuse across both variants in automotive platforms where video capability may be tiered.
What automotive temperature grade does MCIMX6U4AVM08AC support?
MCIMX6U4AVM08AC is rated for −40°C to +125°C junction temperature (Automotive grade, A suffix), as specified in Table 1 of IMX6SDLAEC Rev. 5. This qualification meets AEC-Q100 Grade 2 requirements and enables deployment in dashboard and under-hood environments without derating.
Which security features are implemented in MCIMX6U4AVM08AC?
MCIMX6U4AVM08AC includes ARM TrustZone, CAAM (Cryptographic Acceleration and Assurance Module with 16 KB secure RAM), SNVS (Secure Non-Volatile Storage with RTC), and A-HAB (Advanced High Assurance Boot). These are documented in Sections 1.2 and 8 of IMX6SDLAEC and enable secure boot, AES/SHA/RSA acceleration, and tamper-resistant firmware storage - critical for automotive OTA updates and DRM compliance.
