FAQ

What is the maximum operating frequency of the MIMXRT1064DVL6B?

The MIMXRT1064DVL6B operates at a maximum core frequency of 600 MHz, as confirmed in Table 1 of the IMXRT1064CEC datasheet Rev. 3. This frequency is sustained under commercial temperature conditions (0–85°C junction) with appropriate voltage regulation via the integrated DCDC converter. The MIMXRT1064DVL6B achieves this speed using the Arm Cortex-M7 core with dual 32 KB caches and hardware floating-point unit, enabling deterministic real-time execution without dynamic frequency scaling.

Does the MIMXRT1064DVL6B support IEEE 1588 Precision Time Protocol?

Yes, the MIMXRT1064DVL6B integrates two 10/100M Ethernet controllers (ENET1 and ENET2) with dedicated hardware timestamp units compliant with IEEE 1588-2008. Each MAC supports hardware timestamping of ingress/egress frames with sub-microsecond resolution, enabling synchronization accuracy critical for industrial automation and power grid monitoring. This capability is documented in Section 4.4 ("System modules") and Figure 2 of the IMXRT1064CEC datasheet, and applies specifically to the MIMXRT1064DVL6B variant.

How much on-chip Flash and RAM does the MIMXRT1064DVL6B include?

The MIMXRT1064DVL6B includes 4 MB of on-chip Flash memory and 1 MB of on-chip SRAM. Of the SRAM, 512 KB is flexibly allocatable between instruction TCM (ITCM), data TCM (DTCM), and general-purpose OCRAM in 32 KB granularity, while the remaining 512 KB is fixed as OCRAM. This configuration is explicitly listed for MIMXRT1064DVL6B in Table 1 of the IMXRT1064CEC datasheet and enables XIP execution, low-latency interrupt handling, and large DMA buffers - all integral to the MIMXRT1064DVL6B's real-time performance profile.

What security features are implemented in hardware on the MIMXRT1064DVL6B?

The MIMXRT1064DVL6B implements multiple hardware security accelerators: High Assurance Boot (HAB) for authenticated boot, Data Co-Processor (DCP) supporting AES-128 (ECB/CBC) and SHA-256, Bus Encryption Engine (BEE) for on-the-fly QSPI Flash decryption, True Random Number Generator (TRNG), and Secure Non-Volatile Storage (SNVS) with secure RTC. These features are confirmed in Table 1 and Section 1.1 of the IMXRT1064CEC datasheet and are active in the MIMXRT1064DVL6B without software emulation - enabling secure firmware updates, encrypted storage, and tamper-resistant timekeeping.

Is the MIMXRT1064DVL6B pin-compatible with other i.MX RT1064 variants like MIMXRT1064DVJ6B?

No, the MIMXRT1064DVL6B is not pin-compatible with MIMXRT1064DVJ6B. Although both share identical functionality and electrical specifications, they use different packages: MIMXRT1064DVL6B uses a 196-pin 10×10 mm MAPBGA with 0.65 mm pitch, while MIMXRT1064DVJ6B uses a 196-pin 12×12 mm MAPBGA with 0.8 mm pitch. Pin assignments differ due to distinct ball maps - confirmed in Sections 7.1 and 7.2 of the IMXRT1064CEC datasheet. Therefore, PCB redesign is required when substituting between these variants, and the MIMXRT1064DVL6B requires its own dedicated footprint.
