Product details
Overview
MCIMX286DVM4BR from NXP Semiconductors is an ARM926EJ-S-based applications processor operating at up to 454 MHz, featuring dual FlexCAN interfaces, single 10/100 Ethernet MAC, integrated PMU with Li-ion battery charging, and 128 KB on-chip SRAM - deployed in industrial HMI panels, portable medical devices, and smart energy gateways.
For engineers reviewing the MCIMX286DVM4BR datasheet, MCIMX286DVM4BR pinout, MCIMX286DVM4BR application, or MCIMX286DVM4BR equivalent, key selection considerations include its -20°C to +70°C commercial temperature grade, MAPBGA-289 (14 × 14 mm, 0.8 mm pitch) package, dual CAN support, absence of LCD interface and L2 switch (distinguishing it from i.MX287), and compatibility with mDDR/DDR2/LV-DDR2 memory.
Technical Context
The MCIMX286DVM4BR implements a single 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 is handled by an integrated triple-output DC-DC converter and linear regulators, enabling battery charging, brownout detection across VDDD/VDDA/VDDIO rails, and seamless transition between 5 V and battery power - critical for portable industrial and medical devices requiring runtime continuity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX283DVM4B | Lacks dual CAN and SPDIF; includes LCD interface and touchscreen controller - same CPU, memory, and temperature grade. | Suitable for display-centric HMI where CAN is not required but RGB interface is essential. | Select MCIMX283DVM4B only if LCDIF and touch support are mandatory and dual CAN is unnecessary. |
| MCIMX286CVM4B | Identical feature set but rated for -40°C to +85°C industrial temperature range; same MAPBGA-289 package. | Required for extended-temperature deployments such as outdoor energy meters or factory-floor HMIs exposed to thermal cycling. | Choose MCIMX286CVM4B when ambient operating temperature exceeds 70°C or falls below -20°C. |
Compared with MCIMX286DVM4BR, MCIMX283DVM4B trades dual CAN for LCD capability - making it unsuitable for CAN-based industrial control but better for display-first designs; MCIMX286CVM4B offers identical functionality with extended thermal tolerance, enabling deployment in harsher environments without redesign.

FAQ
What is the maximum operating frequency of the MCIMX286DVM4BR?
The MCIMX286DVM4BR operates at a maximum CPU frequency of 454 MHz using the ARM926EJ-S core. This speed is achievable under recommended voltage conditions (VDDD ≥ 1.35 V) and ambient temperatures within its -20°C to +70°C commercial grade specification. The actual sustained frequency depends on thermal management and power supply stability.
Does the MCIMX286DVM4BR support LCD display interfaces?
No, the MCIMX286DVM4BR does not include an LCD interface (LCDIF). Unlike the i.MX283 and i.MX287 variants, the i.MX286 variant omits the LCD controller block. For display applications, external graphics controllers or alternative i.MX28 family members such as MCIMX283DVM4B must be selected.
What are the supported memory types for the MCIMX286DVM4BR?
The MCIMX286DVM4BR supports mobile DDR (mDDR) at 1.8 V, standard DDR2 at 1.8 V, and LV-DDR2 at 1.5 V, with DDR clock frequencies up to 205 MHz. It also supports SLC and MLC NAND Flash with up to 20-bit BCH ECC via its GPMI interface - enabling flexible, cost-effective memory architectures for embedded storage.
How does the power management unit (PMU) of the MCIMX286DVM4BR handle battery charging?
The MCIMX286DVM4BR's integrated PMU includes a dedicated Li-ion battery charger capable of programmable current limiting, voltage regulation, and thermal monitoring. It supports charging from both 5 V sources and USB ports, with automatic transition between power sources and brownout detection on BATT, VDDA, and VDDIO rails - ensuring safe, reliable operation in portable systems.
Is the MCIMX286DVM4BR pin-compatible with other i.MX28 family members?
Yes, the MCIMX286DVM4BR shares the same MAPBGA-289 package (14 × 14 mm, 0.8 mm pitch) and identical pinout with all other i.MX28 variants including MCIMX280, MCIMX283, and MCIMX287. However, functional differences exist - e.g., MCIMX286DVM4BR includes dual CAN but no LCDIF - so PCB design must align with the specific variant's peripheral enablement.
