NXP Semiconductors MCIMX283CVM4CR2

Overview

MCIMX283CVM4CR2 from NXP Semiconductors (formerly Freescale) is an ARM926EJ-S-based applications processor operating at up to 454 MHz, featuring integrated 128 KB SRAM, dual CAN interfaces, single 10/100 Ethernet MAC, and industrial-grade temperature support (–40°C to +85°C). It targets HMI panels, portable medical devices, and smart energy meters requiring low-power, high-integration SoC solutions with on-chip power management.

For engineers reviewing the MCIMX283CVM4CR2 datasheet, MCIMX283CVM4CR2 pinout, MCIMX283CVM4CR2 application, or MCIMX283CVM4CR2 equivalent, key selection considerations include its MAPBGA-289 package, -40°C to +85°C industrial temperature rating, dual CAN support, absence of LCD interface and L2 switch (distinguishing it from i.MX286/i.MX287), and compatibility with mDDR/DDR2/LV-DDR2 memory and NAND Flash with 20-bit BCH ECC.

Technical Context

The MCIMX283CVM4CR2 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 multiple domain clocks-including 50 MHz/25 MHz outputs for external Ethernet PHYs.

Power delivery is managed by an integrated PMU with triple-output DC-DC switching converter, linear regulators, Li-Ion battery charger, and brownout detection across VDDD, VDDA, VDDIO, and VDD4P2 rails. Memory subsystem includes GPMI supporting up to eight NAND devices with hardware 20-bit BCH ECC, and EMI supporting mobile DDR, DDR2, and LV-DDR2 at up to 205 MHz DDR clock frequency.

FAQ

What is the maximum operating frequency of the MCIMX283CVM4CR2 processor core?

The MCIMX283CVM4CR2 integrates an ARM926EJ-S core rated for operation up to 454 MHz. This frequency is achievable under specified DC operating conditions, including VDDD ≥ 1.35 V and industrial temperature range (–40°C to +85°C). Performance is sustained with on-chip 16 KB instruction and 32 KB data cache, and the core supports JTAG debugging via the DEBUG pin configured for ARM trace macrocell (ETM9).

Does the MCIMX283CVM4CR2 support NAND Flash with hardware error correction?

Yes, the MCIMX283CVM4CR2 includes a General-Purpose Media Interface (GPMI) with integrated Bose-Chaudhuri-Hocquenghem (BCH) encoder/decoder capable of correcting up to 20 bit errors per 512-byte sector. This hardware ECC engine operates transparently during NAND read/write operations and supports up to eight NAND devices with 8-bit data width and 50 MBps I/O speed-critical for reliable data logging in industrial and medical applications.

What power supply configurations does the MCIMX283CVM4CR2 support for battery operation?

The MCIMX283CVM4CR2 supports direct Li-Ion battery operation via the BATT and DCDC_BATT pins (3.10 V to 4.242 V), with an integrated PMU providing battery charging, voltage regulation, and brownout detection. It also supports 5 V external supply with automatic switchover, and generates VDD4P2 (4.2 V) for DC-DC input when 5 V is present. Off-state current is as low as 21 µA (RTC disabled) or 23 µA (RTC enabled) at 4.2 V battery voltage.

How many CAN interfaces does the MCIMX283CVM4CR2 provide, and what protocol versions are supported?

The MCIMX283CVM4CR2 integrates two Controller Area Network (CAN) modules compliant with ISO 11898-1:2003 (CAN 2.0B protocol), supporting data rates up to 1 Mbps. These FlexCAN interfaces operate independently, each with dedicated message buffers and acceptance filtering, and are validated for use in industrial drive control and automotive diagnostics-making MCIMX283CVM4CR2 suitable for CAN-based PLC and sensor network applications.

Is the MCIMX283CVM4CR2 pin-compatible with other i.MX28 variants such as MCIMX286CVM4B?

No, the MCIMX283CVM4CR2 is not pin-compatible with MCIMX286CVM4B or MCIMX287CVM4B. Although all i.MX28 variants use the same MAPBGA-289 package, ball assignments differ significantly-particularly for LCDIF, SPDIF, Ethernet PHY, and L2 switch signals. Pinout validation must be performed using the respective device-specific ball maps (e.g., Section 4.5 "i.MX283 Ball Map" in IMX28CEC Rev. 3), and PCB layout cannot be reused across variants without redesign.
