FAQ
What is the maximum operating frequency of the MIMXRT1042DJM6B?
The MIMXRT1042DJM6B operates at a maximum core frequency of 600 MHz. This speed is achieved using the Arm Cortex-M7 core with integrated 32 KB instruction and data caches, enabling high-throughput deterministic execution for real-time control tasks. The MIMXRT1042DJM6B maintains this frequency across its specified junction temperature range of 0 to +95 °C under proper thermal and power conditions.
Does the MIMXRT1042DJM6B support CAN FD?
Yes, the MIMXRT1042DJM6B includes one FlexCAN module supporting CAN with Flexible Data-Rate (CAN FD), in addition to a second standard FlexCAN 2.0B module. This allows high-speed payload transmission (up to 64 bytes at 8 Mbps) for time-critical industrial networking, while maintaining backward compatibility with legacy CAN nodes. The MIMXRT1042DJM6B implements both controllers with full protocol compliance and hardware message filtering.
What display interfaces does the MIMXRT1042DJM6B support?
The MIMXRT1042DJM6B integrates a parallel RGB LCD interface (LCDIF) supporting 8/16/24-bit data buses and resolutions up to WXGA (1366×768). It also includes the Pixel Processing Pipeline (PXP) for hardware-accelerated 2D graphics operations including alpha blending, chroma keying, and 90°/180°/270° image rotation. The MIMXRT1042DJM6B does not support MIPI DSI or LVDS interfaces - only parallel RGB and smart LCD (8080/MPU) modes.
How much on-chip RAM does the MIMXRT1042DJM6B have, and how is it allocated?
The MIMXRT1042DJM6B contains 512 KB of on-chip RAM implemented as FlexRAM, which can be partitioned in 32 KB increments among I-TCM, D-TCM, and OCRAM. This flexible allocation allows developers to optimize for low-latency instruction fetch (I-TCM), fast data access (D-TCM), or general-purpose buffering (OCRAM) based on real-time requirements. The MIMXRT1042DJM6B does not include additional fixed OCRAM beyond this 512 KB pool.
What package type and dimensions does the MIMXRT1042DJM6B use?
The MIMXRT1042DJM6B uses a 169-pin MAPBGA package with dimensions of 11 × 11 mm and 0.8 mm ball pitch (NXP package code VL). This package is RoHS-compliant and designed for reflow soldering in industrial-grade PCB assemblies. The MIMXRT1042DJM6B shares this mechanical form factor with other DJM6B variants in the i.MX RT1040 family, enabling layout reuse across performance-graded derivatives.
