NXP Semiconductors MCIMX283DVM4C

Overview

MCIMX283DVM4C from NXP Semiconductors is an ARM926EJ-S-based applications processor operating at up to 454 MHz, featuring 128 KB on-chip SRAM, dual CAN interfaces, single 10/100 Ethernet MAC, and integrated PMU with Li-ion battery charging-designed for industrial HMI panels, handheld scanners, and portable medical devices.

For engineers reviewing the MCIMX283DVM4C datasheet, MCIMX283DVM4C pinout, MCIMX283DVM4C application, or MCIMX283DVM4C equivalent, key selection criteria include its –20°C to +70°C commercial temperature grade, MAPBGA-289 (14 × 14 mm, 0.8 mm pitch) package, LCD interface support, and absence of L2 switch or dual Ethernet-distinguishing it from i.MX286/i.MX287 variants.

Technical Context

The MCIMX283DVM4C implements a single ARM926EJ-S core with 16 KB instruction and 32 KB data caches, paired with a dedicated APBH/APBX DMA architecture for peripheral offload. Its clock system uses a 24 MHz crystal input and PLL with fractional dividers to generate domain-specific clocks-including 50 MHz/25 MHz outputs for external Ethernet PHYs.

Power management integrates a triple-output DC-DC converter, linear regulators, and battery charge control with brownout detection on VDDD, VDDA, VDDIO, and VDD4P2 rails. The PMU enables seamless on-the-fly switching between 5 V and battery power while enforcing programmable current limits for combined DCDC input and charge current.

FAQ

What is the maximum operating frequency of the MCIMX283DVM4C CPU core?

The MCIMX283DVM4C integrates an ARM926EJ-S core rated for operation up to 454 MHz under specified voltage and temperature conditions. This frequency is achieved with VDDD ≥1.35 V and ambient temperature within the –20°C to +70°C commercial range. Performance is sustained using the on-chip PLL with fractional divider, and the core includes 16 KB instruction and 32 KB data caches to minimize memory latency. The MCIMX283DVM4C does not support dynamic frequency scaling beyond this fixed maximum.

Does the MCIMX283DVM4C support external DDR2 memory, and what are the voltage requirements?

Yes, the MCIMX283DVM4C supports external DDR2 memory via its EMI controller, operating at up to 205 MHz DDR clock frequency with voltage overdrive. It requires VDDIO.EMI in the range of 1.7–1.9 V for DDR2/LV-DDR2 interfaces, as specified in Table 8 of the IMX28CEC datasheet. The device also supports mobile DDR (1.8 V) and LV-DDR2 (1.5 V), with dedicated I/O banks isolated for EMI signaling to ensure signal integrity.

How many CAN interfaces does the MCIMX283DVM4C include, and are they fully compliant with ISO 11898?

The MCIMX283DVM4C includes two Controller Area Network (CAN) 2.0B protocol-compatible interfaces, designated FlexCAN(2) in the reference manual. Each supports bit rates up to 1 Mbps and conforms to ISO 11898-1 physical layer requirements when paired with an external CAN transceiver. These interfaces are used in industrial control and medical applications per NXP's functional documentation, and no CAN FD capability is present in the MCIMX283DVM4C.

What power supply configurations are supported by the integrated PMU in the MCIMX283DVM4C?

The MCIMX283DVM4C's PMU supports three primary configurations: (1) Li-ion battery input (3.1–4.242 V) with integrated charging and VDD4P2 regulation, (2) 5 V external supply with automatic switchover to battery during dropout, and (3) hybrid operation where DCDC_BATT and VDD5V are both active. The PMU enforces current limits to prevent overloading the 5 V source, prioritizing DCDC input current over battery charge current when thresholds are reached.

Is the MCIMX283DVM4C pin-compatible with other i.MX28 variants such as MCIMX280 or MCIMX286?

Yes, the MCIMX283DVM4C shares the same MAPBGA-289 package (14 × 14 mm, 0.8 mm pitch) and identical pinout with all i.MX28 family members, including MCIMX280, MCIMX286, and MCIMX287. Signal assignments match across variants per Section 4.5 (i.MX283 Ball Map) of the IMX28CEC datasheet. However, functional differences exist-e.g., MCIMX283DVM4C lacks the L2 switch and dual Ethernet of MCIMX287-so PCB layout is reusable but firmware and peripheral enablement must align with variant-specific capabilities.
