NXP Semiconductors MCIMX280DVM4BR

Overview

MCIMX280DVM4BR from NXP Semiconductors is a low-power ARM926EJ-S applications processor running at 454 MHz, featuring 128 KB on-chip SRAM, integrated PMU with Li-ion battery charging, and support for DDR2/LV-DDR2, NAND Flash, USB 2.0 OTG/host, 10/100 Ethernet, and dual CAN interfaces. It targets industrial HMI panels, portable medical devices, and smart energy meters.

For engineers reviewing the MCIMX280DVM4BR datasheet, MCIMX280DVM4BR pinout, MCIMX280DVM4BR application, or MCIMX280DVM4BR equivalent, key selection criteria include its commercial-grade temperature range (–20°C to +70°C), MAPBGA-289 package with 0.8 mm pitch, absence of LCD interface and FlexCAN (vs. i.MX283/286), and fixed 454 MHz CPU clock with no dynamic frequency scaling.

Technical Context

The MCIMX280DVM4BR implements the ARM926EJ-S core with 16 KB instruction cache and 32 KB data cache, coupled to an APBH/APBX DMA architecture supporting memory-mapped I/O and peripheral offload. Its clock subsystem uses a 24 MHz crystal input and PLL-based domain generation with fractional dividers for precise peripheral timing.

Power management is handled by an integrated triple-output DC-DC converter and linear regulators, enabling direct Li-ion battery charging, VDD4P2 generation, brownout detection, and seamless 5 V/battery source switching - all managed without external PMIC intervention.

Key Specifications

Pinout & Package

MCIMX280DVM4BR is housed in a plastic MAPBGA-289 package measuring 14 mm × 14 mm with 0.8 mm ball pitch. Ball assignments follow the i.MX280-specific map defined in Section 4.4 of IMX28CEC Rev. 4.

Compared with MCIMX280DVM4BR, MCIMX283DVM4BR adds display capability at identical power and performance, while MCIMX286DVM4BR extends industrial connectivity with dual CAN and audio output - neither offers pin compatibility, and all three require distinct PCB layouts due to differing peripheral pin allocations.

Availability

MCIMX280DVM4BR is available at Aetrix Electronics and suitable for industrial HMI panels, portable medical devices, and smart energy meters requiring stable component supply across multi-year production cycles.

Supply support for MCIMX280DVM4BR includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors is a global semiconductor company specializing in secure connectivity solutions for automotive, industrial, and IoT applications, with leadership in ARM-based application processors and edge AI acceleration.

The i.MX28 family, including MCIMX280DVM4BR, was designed for cost-sensitive, low-power embedded systems requiring rich peripheral integration, secure boot, and long-term industrial availability - not general-purpose computing.

FAQ

What is the maximum operating frequency of the MCIMX280DVM4BR CPU core?

The MCIMX280DVM4BR integrates an ARM926EJ-S core rated for operation at 454 MHz under specified voltage and temperature conditions. This frequency is fixed and not dynamically scalable; it is achieved with a 1.35–1.55 V VDDD supply and validated across the –20°C to +70°C ambient range per IMX28CEC Rev. 4.

Does the MCIMX280DVM4BR support CAN bus communication?

No, the MCIMX280DVM4BR does not include FlexCAN modules. According to Table 2 in the i.MX28 documentation, CAN functionality is only present in the i.MX286 and i.MX287 variants. The MCIMX280DVM4BR part number explicitly denotes the base feature set without CAN, making it unsuitable for CAN-based industrial networks unless paired with an external CAN controller.

What package type and dimensions does the MCIMX280DVM4BR use?

The MCIMX280DVM4BR uses a MAPBGA-289 package with 14 mm × 14 mm body size and 0.8 mm ball pitch. This is confirmed in Table 1 of the IMX28CEC datasheet and physically documented in Section 4.1. The ball map for MCIMX280 is provided on page 63, and thermal pad layout guidelines are included in the package drawings.

Can the MCIMX280DVM4BR drive an LCD display directly?

No, the MCIMX280DVM4BR lacks the LCD interface (LCDIF) block. As shown in Table 2 of the i.MX28 functional differences, LCDIF is absent in the i.MX280 variant and first appears in i.MX283. Therefore, MCIMX280DVM4BR cannot generate RGB or DOTCLK signals; external display controllers or bridge ICs are required for TFT or segment LCD integration.

What power supply rails are required for proper operation of the MCIMX280DVM4BR?

The MCIMX280DVM4BR requires five primary supply domains: VDD5V (4.75–5.25 V), BATT/DCDC_BATT (3.1–4.242 V), VDDA (1.62–2.10 V analog), VDDD (1.35–1.55 V core), and VDDIO (3.0–3.6 V I/O). These are defined in Tables 6–8 of IMX28CEC Rev. 4, with strict sequencing requirements enforced by the internal PMU.
