Product details
Overview
MCIMX6U4AVM08ADR 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 integrates 512 KB L2 cache, dual CAN 2.0B controllers, HDMI 1.4, and Gigabit Ethernet for infotainment head units and digital instrument clusters.
For engineers reviewing the MCIMX6U4AVM08ADR datasheet, MCIMX6U4AVM08ADR pinout, MCIMX6U4AVM08ADR application, or MCIMX6U4AVM08ADR equivalent, key selection criteria include automotive temperature range (−40°C to +125°C), MAPBGA-289 (21 × 21 mm, 0.8 mm pitch) package compatibility, dual-core A9 performance with GPU-only multimedia capability, and MLB bus integration for MOST network connectivity.
Technical Context
The MCIMX6U4AVM08ADR implements a symmetric dual-core Arm Cortex-A9 MPCore platform with TrustZone security, 32 KB L1 instruction and data caches per core, and a shared 512 KB unified L2 cache. Its memory subsystem supports 32/64-bit DDR3/DDR3L/LPDDR2-800 interfaces with interleaving mode enabled for dual-channel LPDDR2.
This SoC integrates dedicated hardware accelerators including GPU3Dv5 (OpenGL ES 2.0), GPU2Dv2 (BitBlt), ASRC (asynchronous sample rate conversion for multi-channel audio), and CAAM (Cryptographic Acceleration and Assurance Module with 16 KB secure RAM). It omits the Video Processing Unit (VPU) and EPDC (Electrophoretic Display Controller) present in higher-tier variants.
Key Specifications

Pinout & Package
MCIMX6U4AVM08ADR is housed in a plastic MAPBGA package (21 × 21 mm, 0.8 mm pitch) with 289 solder balls. Pin assignments follow the i.MX 6DualLite functional contact map defined in Section 6.2 of IMX6SDLAEC Rev. 9. The ball grid includes dedicated power domains (VDD_ARM, VDD_SOC, VDD_HIGH), differential clock inputs (OSC_IN/OSC_OUT), and function-muxed I/O banks supporting LVDS, MIPI DSI/CSI-2, HDMI, and PCIe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_ARM | Core voltage supply | 1.2 V ±3% regulated input for Arm Cortex-A9 cores and L1/L2 caches - requires low-noise, high-PSRR LDO or DC-DC converter. |
| VDD_SOC | SoC logic voltage | 1.1 V ±3% supply for system logic, GPC, CCM, and peripheral controllers - decoupled separately from VDD_ARM for dynamic voltage scaling. |
| OSC_IN / OSC_OUT | Crystal oscillator interface | 24 MHz fundamental-mode crystal connection - mandatory for USB PHY clocking and system timing reference. |
| ENET_MDIO / ENET_MDC | Ethernet management interface | I²C-like serial interface for configuring external Gigabit Ethernet PHY registers - supports IEEE 802.3 clause 22/45 register access. |
| CAN1_TX / CAN1_RX | FlexCAN channel 1 differential pair | High-speed CAN 2.0B physical layer signals - require 120 Ω termination at network ends and common-mode choke filtering. |
| MLB_CLK / MLB_DATA | MEDIA LB bus interface | Source-synchronous 150 Mbps or 50 Mbps differential signaling for MOST25/50/150 networks - used for audio/video transport in premium automotive systems. |
Key Features
| Feature | Design Value |
|---|---|
| Smart Speed Technology | Dynamic voltage and frequency scaling (DVFS) across CPU, GPU, and memory domains - reduces active power by up to 40% during partial-load HMI operation. |

FAQ
What is the maximum operating temperature specification for MCIMX6U4AVM08ADR?
The MCIMX6U4AVM08ADR is rated for automotive temperature grade A (−40°C to +125°C junction temperature), validated per AEC-Q100 Grade 2 requirements. This specification applies to the full operating voltage range and all supported clock frequencies, ensuring reliable functionality in under-hood and dashboard environments where ambient temperatures exceed 85°C.
Does MCIMX6U4AVM08ADR support HDMI 1.4 output?
Yes, MCIMX6U4AVM08ADR includes a fully integrated HDMI 1.4 transmitter supporting up to 1080p60 resolution with HDCP 1.4 compliance. The interface uses TMDS differential pairs routed through dedicated ball groups and requires external level-shifting and ESD protection per HDMI specification; no additional video encoder IC is needed.
How does the absence of VPU affect multimedia capabilities in MCIMX6U4AVM08ADR?
The MCIMX6U4AVM08ADR excludes the Video Processing Unit (VPU), meaning it cannot perform hardware-accelerated video decode (H.264, MPEG-4, VC-1) or encode. All video playback must be handled in software using CPU resources, limiting practical resolution to 720p30 with significant CPU load. GPU3Dv5 and GPU2Dv2 remain fully functional for UI rendering and 2D graphics.
What security features are implemented in MCIMX6U4AVM08ADR?
MCIMX6U4AVM08ADR integrates Arm TrustZone, CAAM (with NIST-certified DRBG and SHA-256/RSA-2048 engines), SNVS (Secure RTC and OTP storage), CSU (eFUSE-based security policy), and A-HAB v4 for secure boot. These features enable cryptographic operations, secure firmware authentication, and tamper-resistant key storage-all verified in the i.MX 6Solo/6DualLite Security Reference Manual (IMX6DQ6SDLSRM).
Is MCIMX6U4AVM08ADR pin-compatible with other i.MX 6DualLite automotive variants?
Yes, MCIMX6U4AVM08ADR shares the same MAPBGA-289 package (21 × 21 mm, 0.8 mm pitch) and identical ball map with all automotive-grade i.MX 6DualLite parts including MCIMX6U6AVM08ADR and MCIMX6U1AVM08ADR. Signal muxing and power domain assignments are consistent across the family, enabling PCB reuse when migrating between GPU-only, GPU+VPU, or MLB-only configurations.
