NXP Semiconductors MCIMX283DVM4B

Overview

MCIMX283DVM4B 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 power management for Li-Ion battery charging - deployed in industrial HMI panels and portable medical devices.

For engineers reviewing the MCIMX283DVM4B datasheet, MCIMX283DVM4B pinout, MCIMX283DVM4B application, or MCIMX283DVM4B equivalent, key selection factors 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 found in i.MX287.

Technical Context

The MCIMX283DVM4B implements the ARM926EJ-S core with 16 KB instruction and 32 KB data cache, supported by CoreSight ETM9 debug infrastructure and parallel JTAG interface. Its clock architecture uses a configurable PLL with fractional dividers and crystal-derived XCLK for low-power peripherals.

Power sequencing is managed by an integrated PMU containing a triple-output DC-DC converter, linear regulators, battery charger, and brownout detection across VDDD, VDDA, VDDIO, and VDD4P2 rails. Memory subsystem includes EMI supporting DDR2, LV-DDR2, and mDDR up to 205 MHz, plus GPMI NAND controller with 20-bit BCH ECC.

Key Specifications

Pinout & Package

MCIMX283DVM4B is housed in a plastic MAPBGA-289 package (14 × 14 mm, 0.8 mm pitch), with ball assignments defined per Section 4.5 ("i.MX283 Ball Map") of the IMX28CEC Rev. 4 datasheet.

FAQ

What is the maximum operating frequency of the MCIMX283DVM4B?

The MCIMX283DVM4B features 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 with fractional divider configuration, and requires VDDD ≥ 1.35 V for stable operation per the IMX28CEC Rev. 4 datasheet Section 3.1.2.

Does the MCIMX283DVM4B support NAND Flash with hardware ECC?

Yes, the MCIMX283DVM4B integrates a General-Purpose Media Interface (GPMI) with built-in 20-bit BCH error correction coding, supporting reliable operation with SLC and MLC NAND Flash devices. This eliminates the need for external ECC logic and is documented in Section 1.1 and Table 3 of the IMX28CEC Rev. 4 datasheet.

What is the temperature range specification for the MCIMX283DVM4B?

The MCIMX283DVM4B is specified for a commercial ambient operating temperature range of –20°C to +70°C, with a corresponding junction temperature range of –20°C to +85°C. This is explicitly listed in Table 1 ("Ordering Information") of the IMX28CEC Rev. 4 datasheet and distinguishes it from industrial-grade variants like MCIMX283CVM4B.

Can the MCIMX283DVM4B operate without external DRAM?

Yes, the MCIMX283DVM4B includes 128 KB of on-chip SRAM, which is sufficient to run lightweight RTOS-based applications without external DRAM. This capability is highlighted in the Introduction section of the IMX28CEC Rev. 4 datasheet as enabling "eliminating external RAM in applications with small footprint RTOS."

How many CAN interfaces does the MCIMX283DVM4B provide?

The MCIMX283DVM4B provides two Controller Area Network (FlexCAN) 2.0B-compatible interfaces, as confirmed in Table 2 ("i.MX28 Functional Differences") and Section 1.1 of the IMX28CEC Rev. 4 datasheet. Both interfaces support 1 Mbps operation and are implemented with dedicated signal pins (CAN1_TX/RX and CAN2_TX/RX).
