Product details
Overview
MCIMX286CVM4C from NXP Semiconductors is an industrial-grade ARM926EJ-S applications processor operating at up to 454 MHz, featuring dual FlexCAN interfaces, single 10/100 Ethernet MAC, 128 KB on-chip SRAM, and integrated PMU with Li-ion battery charging - deployed in smart energy gateways and industrial HMI panels.
For engineers reviewing the MCIMX286CVM4C datasheet, MCIMX286CVM4C pinout, MCIMX286CVM4C application, or MCIMX286CVM4C equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), MAPBGA-289 package compatibility, dual-CAN support, and absence of LCD interface or L2 switch compared to i.MX287.
Technical Context
The MCIMX286CVM4C implements the ARM926EJ-S core with 16 KB instruction and 32 KB data cache, supported by CoreSight ETM9 for real-time debug. Its clock architecture uses a 24 MHz crystal input and PLL with fractional dividers to generate domain-specific clocks including 50/25 MHz outputs for external Ethernet PHYs.
Power management integrates a triple-output DC-DC converter, linear regulators, and battery charge control with VDD4P2 generation from 5 V, enabling seamless transition between battery and wall-power operation. Memory subsystem supports mobile DDR, DDR2, and LV-DDR2 up to 205 MHz, plus NAND Flash with 20-bit BCH ECC across up to eight devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX287CVM4C | Includes dual Ethernet MACs and integrated 3-port L2 switch; adds LCDIF and S/PDIF; same CPU, memory, and peripheral base. | Required for applications needing redundant Ethernet links or embedded switching (e.g., industrial routers); not suitable where LCDIF is unused and BOM cost must be minimized. | Select MCIMX287CVM4C only if dual Ethernet or L2 switching functionality is mandatory; otherwise MCIMX286CVM4C offers lower unit cost and identical CAN/Ethernet core capability. |
| MCIMX283CVM4C | Lacks FlexCAN interfaces entirely; retains single Ethernet MAC, same CPU speed, SRAM, and PMU; shares identical package and pinout. | Suitable for non-automotive/industrial applications where CAN is unnecessary (e.g., media phones, basic gateways); cannot replace MCIMX286CVM4C in CAN-dependent designs. | Choose MCIMX283CVM4C when CAN is absent from system architecture; verify pin compatibility but confirm CAN signal traces are unpopulated or repurposed. |
Compared with MCIMX286CVM4C, MCIMX287CVM4C adds Ethernet switching and LCD support at higher cost and power, while MCIMX283CVM4C removes CAN entirely - making MCIMX286CVM4C the optimal balance of industrial I/O, security, and cost for CAN-centric edge nodes.

FAQ
What is the maximum operating frequency of the MCIMX286CVM4C CPU core?
The MCIMX286CVM4C 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 VDDD = 1.55 V and proper thermal management; actual achievable speed depends on voltage scaling and junction temperature, as specified in Table 8 of the IMX28CEC datasheet.
Does the MCIMX286CVM4C support external DDR2 memory, and what are the voltage requirements?
Yes, the MCIMX286CVM4C supports external DDR2 memory at 1.8 V via its EMI controller. The VDDIO.EMI supply must be regulated between 1.7 V and 1.9 V for DDR2 operation, and the device supports clock frequencies up to 205 MHz with voltage overdrive. LV-DDR2 (1.5 V) and mobile DDR (1.8 V) are also supported with corresponding voltage rails.
How many CAN interfaces does the MCIMX286CVM4C provide, and are they fully compliant with ISO 11898-2?
The MCIMX286CVM4C integrates two FlexCAN 2.0B modules, each compliant with the CAN 2.0B protocol specification. While the MCU itself implements the protocol layer, full ISO 11898-2 physical layer compliance requires an external CAN transceiver (e.g., TJA1042) connected to the CAN_TX/CAN_RX pins - which the MCIMX286CVM4C drives with appropriate slew rate and voltage levels.
Is the MCIMX286CVM4C pin-compatible with other i.MX28 variants such as MCIMX283CVM4C?
Yes, the MCIMX286CVM4C shares identical MAPBGA-289 package dimensions, ball pitch (0.8 mm), and mechanical footprint with all i.MX28 family members including MCIMX283CVM4C and MCIMX287CVM4C. However, electrical pin functions differ - notably, CAN0/CAN1 pins on MCIMX286CVM4C are NC on MCIMX283CVM4C, requiring board-level validation before substitution.
What security features are implemented in hardware on the MCIMX286CVM4C?
The MCIMX286CVM4C includes hardware-accelerated security features: 128-bit AES decryption for secure boot, SHA-1 and SHA256 hashing engines, High Assurance Boot (HAB4) for verified firmware loading, and a read-only unique ID for DRM. These are implemented in the DCP and OCOTP modules and operate independently of software execution, ensuring root-of-trust integrity from power-on reset.
