NXP Semiconductors MCIMX286DVM4B

Overview

MCIMX286DVM4B from NXP Semiconductors is a low-power, high-performance ARM926EJ-S™ applications processor running at up to 454 MHz, featuring dual CAN interfaces, single 10/100 Ethernet MAC, and integrated power management with Li-Ion battery charging. It includes 128 KB on-chip SRAM, 128 KB mask-ROM, and supports mobile DDR, DDR2, LV-DDR2, and NAND Flash with 20-bit BCH ECC - deployed in industrial HMI panels and portable medical devices.

For engineers reviewing the MCIMX286DVM4B datasheet, MCIMX286DVM4B pinout, MCIMX286DVM4B application, or MCIMX286DVM4B 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 FlexCAN support, absence of LCD interface and L2 switch (distinguishing it from i.MX287), and compatibility with USB 2.0 OTG + host PHYs.

Technical Context

The MCIMX286DVM4B implements an ARM926EJ-S core with 16 KB instruction cache and 32 KB data cache, coupled to APBH/APBX DMA bridges for peripheral data movement. Its clock architecture uses a 24 MHz crystal input and PLL-based fractional dividers to generate domain-specific clocks including 50/25 MHz outputs for external Ethernet PHYs.

Power sequencing is managed by an integrated PMU with triple-output DC-DC switching converter, four linear regulators, and programmable current-limited Li-Ion charging - enabling direct battery operation and seamless 5 V/battery switchover. The device supports IEEE 1588 hardware timestamping and full-duplex SAIF audio with 8–192 kHz sample rates.

FAQ

What is the maximum operating frequency of the ARM926EJ-S core in MCIMX286DVM4B?

The MCIMX286DVM4B integrates an ARM926EJ-S core rated for operation up to 454 MHz under specified voltage and temperature conditions. This frequency is achieved using the internal PLL driven by the 24 MHz crystal input, with fractional dividers enabling precise clock domain generation for CPU, memory, and peripherals. The actual sustained frequency depends on VDDD supply (1.35–1.55 V) and ambient temperature (–20°C to +70°C).

Does MCIMX286DVM4B support LCD display interfaces?

No, MCIMX286DVM4B does not include an LCD interface (LCDIF). While the i.MX286 variant supports LCD functionality per Table 2 in the datasheet, the MCIMX286DVM4B part number is explicitly documented in NXP's ordering table as having the same functional set as i.MX286 - which includes LCDIF. However, cross-referencing Table 2 confirms i.MX286 has "Yes" under LCD Interface, and MCIMX286DVM4B is an i.MX286-series part with commercial temperature grade. Therefore, MCIMX286DVM4B does support LCDIF for 24-bit RGB and system-mode displays.

What power supply configurations does MCIMX286DVM4B support for battery operation?

MCIMX286DVM4B supports direct Li-Ion battery operation via the BATT and DCDC_BATT pins (3.10–4.242 V), with integrated charging circuitry capable of programmable current limiting. Its PMU enables automatic switchover between 5 V and battery power, provides VDD4P2 (4.2 V) rail for DC-DC operation with depleted batteries, and includes brownout detection on VDDD, VDDA, VDDIO, and 5 V supplies - all critical for uninterrupted operation in handheld scanners and portable medical devices.

How many CAN interfaces does MCIMX286DVM4B provide, and what protocol versions are supported?

MCIMX286DVM4B provides two Controller Area Network (FlexCAN) interfaces compliant with CAN 2.0B protocol, supporting bit rates up to 1 Mbps. Both interfaces include dedicated TX/RX pins, message buffering, and hardware acceptance filtering - enabling robust fieldbus communication in industrial drive systems and automotive diagnostic tools without external CAN transceivers.

Is MCIMX286DVM4B pin-compatible with other i.MX28 family members like MCIMX283DVM4B?

Yes, MCIMX286DVM4B is pin-compatible with MCIMX283DVM4B and other i.MX28 MAPBGA-289 variants (e.g., MCIMX280DVM4B), sharing identical 14 × 14 mm, 0.8 mm pitch ball map per Section 4.6 of the datasheet. However, functional differences exist - MCIMX286DVM4B includes SPDIF and LCDIF, while MCIMX283DVM4B omits them - so PCB layout is interchangeable but firmware and peripheral initialization must match the specific variant's capabilities.
