Product details
Overview
MCIMX280DVM4C from NXP Semiconductors is a low-power ARM926EJ-S applications processor running at up to 454 MHz, featuring 128 KB on-chip SRAM, integrated PMU with Li-ion battery charging, and dual CAN, USB 2.0 OTG/host, 10/100 Ethernet, and 5 UARTs - deployed in industrial HMI panels, portable medical devices, and smart energy meters.
For engineers reviewing the MCIMX280DVM4C datasheet, MCIMX280DVM4C pinout, MCIMX280DVM4C application, or MCIMX280DVM4C equivalent, key selection criteria include its –20°C to +70°C commercial temperature grade, MAPBGA-289 package, absence of LCD interface and FlexCAN (vs. i.MX283/286), and verified support for mDDR/DDR2/LV-DDR2, NAND with 20-bit BCH ECC, and SPDIF-free configuration.
Technical Context
The MCIMX280DVM4C implements an ARM926EJ-S core with 16 KB instruction and 32 KB data cache, ETM9 debug support, and parallel JTAG interface. Its memory subsystem includes 128 KB mask-ROM, 128 KB SRAM, and external memory interface supporting mobile DDR, DDR2, and LV-DDR2 up to 205 MHz DDR clock frequency.
Connectivity is defined by four SSPs (SDIO/MMC/SPI), two I²C interfaces, five AUARTs (up to 3.25 Mbps), one debug UART, dual CAN controllers, single 10/100 Ethernet MAC, USB 2.0 OTG + host PHYs, and 16-channel LRADC with 8 virtual channel mapping. It lacks LCDIF, PXP, S/PDIF Tx, and L2 switch - distinguishing it from i.MX283/286/287 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM926EJ-S @ up to 454 MHz - delivers deterministic real-time performance for RTOS-based industrial control without external cache. |
| On-chip Memory | 128 KB SRAM + 128 KB ROM - enables boot-from-ROM and eliminates external RAM in footprint-constrained embedded designs. |
| External Memory Support | mDDR/DDR2/LV-DDR2 up to 205 MHz DDR clock - supports cost-optimized memory choices with voltage overdrive capability. |
| NAND Interface | GPMI with up to 20-bit BCH ECC across 8 devices - ensures robust data integrity for high-endurance flash storage in metering and HMI. |
| Connectivity Peripherals | 2× CAN 2.0B, 1× 10/100 Ethernet MAC, 5× AUART, 4× SSP, 2× I²C, USB 2.0 OTG + host - provides full industrial fieldbus and serial I/O without external bridge ICs. |

Pinout & Package
MCIMX280DVM4C is housed in a 14 × 14 mm MAPBGA-289 package with 0.8 mm pitch, requiring standard BGA reflow profile and 6-layer PCB routing for signal integrity and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BATT / DCDC_BATT | Battery input / DC-DC converter supply | Direct connection to Li-ion cell (3.1–4.24 V); enables on-chip charging and seamless 5 V/battery power transition. |
| VDD5V | 5 V system supply input | Provides power to internal LDOs and USB PHY; supports 4.75–5.25 V with transient tolerance up to 7 V (t < 30 ms). |
| VDDA | Analog core supply | 1.62–2.10 V rail powering ADCs, crystal oscillators, and RTC - requires dedicated low-noise filtering. |
| VDDD | Digital core supply | 1.35–1.55 V (frequency-dependent); lower voltage reduces dynamic power at 454 MHz operation. |
| VDDIO / VDDIO.EMI | I/O and EMI interface supply | Configurable 1.7–3.6 V range supports mixed-voltage peripherals (e.g., 1.8 V DDR2 + 3.3 V UARTs). |
| RESETN | Active-low reset input | Pulled up internally (10 kΩ); asserts chip reset when driven low - no external pull-up required. |
| PSWITCH | Power-on recovery control | Used to enter firmware recovery mode; must be tied to VDDIO via 10 kΩ resistor during boot failure. |
| XTALI / XTALO | Main 24 MHz crystal oscillator inputs | Drive on-chip PLLs; require external 24 MHz crystal and load capacitors per layout guidelines. |
| RTC_XTALI / RTC_XTALO | 32.768 kHz RTC crystal inputs | Enable low-power real-time clock operation independent of main domain; retain time in deep-sleep modes. |
| USB_DP / USB_DN | USB 2.0 differential data lines | Integrated PHY supports FS/HS modes; direct connection to USB connector - no external transceiver needed. |

FAQ
What is the maximum operating frequency of the MCIMX280DVM4C?
The MCIMX280DVM4C operates at up to 454 MHz using its ARM926EJ-S core. This frequency is achievable under specified DC operating conditions, including VDDD ≥ 1.35 V and ambient temperature within –20°C to +70°C. Performance scales with core voltage and thermal headroom, and the device includes dynamic voltage/frequency scaling support via its integrated PMU.
Does the MCIMX280DVM4C support NAND Flash with hardware ECC?
Yes, the MCIMX280DVM4C supports NAND Flash with hardware-accelerated BCH ECC through its GPMI controller, capable of correcting up to 20 bit errors per 512-byte sector. This feature is fully implemented in silicon and requires no software overhead, making it ideal for reliable firmware storage in smart meters and industrial HMIs where NAND endurance is critical.
What power supply rails does the MCIMX280DVM4C require?
The MCIMX280DVM4C requires five primary supply rails: VDD5V (4.75–5.25 V), VDDA (1.62–2.10 V), VDDD (1.35–1.55 V), VDDIO (1.7–3.6 V), and VDDIO.EMI (1.425–1.625 V for DDR2/LV-DDR2). The integrated PMU generates regulated outputs from BATT or VDD5V, but external filtering and sequencing per NXP's reference design remain mandatory for stable operation.
Is the MCIMX280DVM4C pin-compatible with other i.MX28 variants like MCIMX283DVM4C?
Yes, the MCIMX280DVM4C is pin-compatible with MCIMX283DVM4C, MCIMX286DVM4C, and other i.MX28 MAPBGA-289 variants. All share identical ball map, mechanical footprint, and power/ground assignments. Functional differences (e.g., LCDIF presence) are implemented internally - allowing hardware reuse across variants when software accommodates peripheral availability.
Does the MCIMX280DVM4C include security features for secure boot?
Yes, the MCIMX280DVM4C includes hardware-enforced secure boot via High Assurance Boot (HAB4), 128-bit AES decryption engine, SHA-1/SHA-256 hashing accelerators, and 1280-bit OCOTP ROM for storing cryptographic keys and unique device IDs.
