NXP Semiconductors MCIMX6Q4AVT08AC

Overview

MCIMX6Q4AVT08AC from NXP Semiconductors is an automotive-grade i.MX 6Quad application processor featuring four Arm Cortex-A9 cores operating at 852 MHz, integrated GPU (Vivante GC2000), no VPU, and FCPBGA-624 package (21 × 21 mm, 0.8 mm pitch). It delivers 2D/3D graphics acceleration, dual CAN interfaces, HDMI 1.4, and DDR3/DDR3L/LPDDR2 memory support for infotainment head units.

For engineers reviewing the MCIMX6Q4AVT08AC datasheet, MCIMX6Q4AVT08AC pinout, MCIMX6Q4AVT08AC application, or MCIMX6Q4AVT08AC equivalent, key selection criteria include automotive temperature grade (−40°C to +125°C), absence of hardware video decode engine, GPU-only multimedia capability, and compatibility with i.MX 6Quad boot ROM and security features including HABv4 and CAAM.

Technical Context

The MCIMX6Q4AVT08AC implements a quad-core Arm Cortex-A9 MPCore platform with TrustZone, 32 KB L1 instruction and data caches per core, and a shared 1 MB L2 cache. It integrates Vivante GC2000 3D GPU (OpenGL ES 2.0, OpenCL support) but omits the VPU found in '6' variants-limiting hardware-accelerated video decode to JPEG only, not H.264/VC-1.

Its system architecture includes dual FlexCAN 2.0B controllers (1 Mbps), ASRC for multi-channel audio sample rate conversion, ESAI and SSI for automotive-grade audio I/O, and a 64-bit MMDC supporting DDR3-1066, DDR3L-1066, and LPDDR2-800. Boot configuration is managed via dedicated pins and fused OTP settings for secure boot enforcement.

Key Specifications

Pinout & Package

MCIMX6Q4AVT08AC uses a 624-ball Fine-Pitch Chip Array Ball Grid Array (FCPBGA) package measuring 21 mm × 21 mm with 0.8 mm ball pitch and integrated heat spreader lid. Pin assignments follow the i.MX 6Quad Automotive signal naming convention (IMX6DQAEC Rev. 6), with functional groups including DDR3 address/control/data, ARM core debug (JTAG/SWD), multiple I/O banks (LVDS, MIPI DSI/CSI, HDMI, USB PHY), and automotive-specific interfaces (CAN_H/L, MLB_CLK/DATA).

FAQ

Does MCIMX6Q4AVT08AC support hardware-accelerated H.264 video decoding?

No, MCIMX6Q4AVT08AC does not include a Video Processing Unit (VPU). It supports only JPEG encode/decode in hardware via the IPUv3H; H.264, VC-1, or MPEG-4 video decoding must be performed in software on the Cortex-A9 cores or offloaded to an external codec. This distinguishes it from the '6' suffix variants like MCIMX6Q6AVT08AC, which integrate the full VPU.

What is the maximum DDR3 memory speed supported by MCIMX6Q4AVT08AC?

MCIMX6Q4AVT08AC supports DDR3-1066 (532 MHz) operation, delivering up to 8.5 GB/s peak bandwidth across its 64-bit interface. This is confirmed in Section 4.10 (Multi-Mode DDR Controller) of the IMX6DQAEC datasheet Rev. 6. The controller also supports DDR3L-1066 and LPDDR2-800, with on-die termination calibration required for signal integrity.

Is MCIMX6Q4AVT08AC qualified for automotive use, and what is its temperature range?

Yes, MCIMX6Q4AVT08AC is an automotive-grade part qualified per AEC-Q100 with a junction temperature range of −40°C to +125°C. Its 'A' suffix denotes automotive temperature grade, and the FCPBGA package includes a heat spreader lid optimized for under-dash thermal environments. This rating is explicitly stated in Table 1 of the IMX6DQAEC datasheet.

How does the security architecture of MCIMX6Q4AVT08AC enable secure boot?

MCIMX6Q4AVT08AC implements Advanced High Assurance Boot (A-HABv4) with SHA-256 hashing, 2048-bit RSA signature verification, and fuse-based policy enforcement via the CSU. During boot, the ROM code validates signed images using keys stored in eFUSE or OCOTP, and only permits execution if signatures match. This process is identical across all i.MX 6Quad automotive variants, including MCIMX6Q4AVT08AC.

Can MCIMX6Q4AVT08AC drive multiple displays simultaneously, and which interfaces are available?

Yes, MCIMX6Q4AVT08AC supports up to four active displays concurrently via its integrated display subsystem: one parallel RGB interface (24-bit, up to WUXGA@60Hz), one LVDS port (dual-channel, up to WUXGA@60Hz), HDMI 1.4 (1080p@60Hz), and MIPI DSI (2-lane, 1 Gbps/lane). Display composition is handled by dual IPUv3H units and the GC2000 GPU, with total raw pixel throughput up to 450 Mpixels/sec.
