FAQ

What is the maximum operating frequency of the MCIMX286CVM4CR2 processor core?

The MCIMX286CVM4CR2 features an ARM926EJ-S core rated for operation up to 454 MHz under industrial temperature conditions (–40°C to +85°C). This frequency is sustained with proper thermal design and VDDD supply within 1.35–1.55 V, as specified in IMX28CEC Rev. 3, Table 8. The core includes 16 KB instruction and 32 KB data caches to maintain throughput at this speed.

Does the MCIMX286CVM4CR2 support NAND Flash with hardware ECC?

Yes, the MCIMX286CVM4CR2 integrates a General-Purpose Media Interface (GPMI) supporting up to eight NAND Flash devices with configurable 2–20 bit BCH ECC correction. The hardware accelerator handles error detection and correction transparently during read/write operations, enabling robust data storage on SLC and MLC NAND in industrial environments per IMX28CEC Section 1.1 and Table 3.

What power supply configurations does the MCIMX286CVM4CR2 PMU support?

The MCIMX286CVM4CR2 PMU supports three primary configurations: (1) direct Li-ion battery input (3.1–4.242 V) with integrated charging, (2) 5 V adapter input with automatic power-path switching, and (3) hybrid operation where VDD5V powers the system while simultaneously charging the battery. The PMU generates VDD4P2 (4.2 V), VDDA, VDDD, and multiple VDDIO rails with sequencing control per IMX28CEC Section 1 and Table 8.

Is the MCIMX286CVM4CR2 pin-compatible with other i.MX28 variants?

Yes, the MCIMX286CVM4CR2 shares the same MAPBGA-289 package (14 × 14 mm, 0.8 mm pitch) and identical ball map with MCIMX280, MCIMX283, and MCIMX287 variants. Pin functions are consistent across the family per IMX28CEC Section 4.6, enabling PCB reuse when migrating between models - though peripheral enablement (e.g., LCD, S/PDIF, dual Ethernet) varies by silicon version.

What security features are implemented in hardware on the MCIMX286CVM4CR2?

The MCIMX286CVM4CR2 includes hardware-accelerated security features: 128-bit AES decryption for secure boot, SHA-1 and SHA-256 hashing engines, High Assurance Boot (HAB4) for signature verification, and a read-only unique ID for DRM. These are implemented in the DCP (Data Co-Processor) and OCOTP modules, enabling tamper-resistant firmware updates and data integrity in medical and energy applications per IMX28CEC Section 1.1 and Table 4.
