Product details
Overview
MCIMX280CVM4B from NXP Semiconductors is an ARM926EJ-S-based applications processor operating at up to 454 MHz, featuring 128 KB on-chip SRAM, integrated PMU with Li-ion battery charging, and dual CAN, single 10/100 Ethernet, USB 2.0 OTG + host, and 5 AUARTs - deployed in industrial HMI panels, portable medical devices, and smart energy gateways.
For engineers reviewing the MCIMX280CVM4B datasheet, MCIMX280CVM4B pinout, MCIMX280CVM4B application, or MCIMX280CVM4B equivalent, key selection considerations include its –40°C to +85°C industrial temperature rating, MAPBGA-289 (14 × 14 mm, 0.8 mm pitch) package, absence of LCD interface and FlexCAN (vs. i.MX283/286), and reliance on external memory interfaces including mDDR/DDR2/LV-DDR2 and NAND with 20-bit BCH ECC.
Technical Context
The MCIMX280CVM4B implements the 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 domain-specific clocks for peripherals including USB, Ethernet, and audio subsystems.
Power sequencing is managed entirely by the integrated PMU, which includes a triple-output DC-DC converter, linear regulators, battery charge control, and brownout detection across VDDD, VDDA, VDDIO, and VDD4P2 rails - enabling direct Li-ion battery operation and seamless 5 V/battery switchover without external circuitry.

Pinout & Package
MCIMX280CVM4B is housed in a plastic MAPBGA-289 package (14 × 14 mm, 0.8 mm pitch), with ball assignments defined per i.MX280 Ball Map (Section 4.4, IMX28CEC Rev. 4). Power, ground, and signal balls are organized into dedicated banks for EMI, analog, core, and I/O domains - requiring strict adherence to recommended decoupling and routing rules per NXP reference design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 | VDDA | Analog core supply (1.62–2.10 V) - must be filtered separately from digital supplies to maintain ADC and RTC accuracy. |
| A2 | VDDD | Digital core supply (1.35–1.55 V @ 454 MHz) - voltage scaling directly impacts CPU frequency and power consumption. |
| E1 | VDDIO | Non-EMI I/O supply (3.0–3.6 V) - powers GPIO, UART, I²C, and SSP; level-shifted for interfacing with 3.3 V peripherals. |
| H1 | VDDIO.EMI | EMI I/O supply (1.7–1.9 V for DDR2/mDDR) - critical for stable memory interface timing; requires low-noise regulation. |
| K1 | BATT | Li-ion battery input (3.1–4.242 V) - feeds DC-DC converter and enables battery charging via integrated PMU. |
| M1 | RESETN | Active-low reset input - internally pulled up to VDDIO33; no external pull-up required for standard operation. |
| P1 | PSWITCH | Power-on/recovery control - used to enter firmware recovery mode when driven via 10 kΩ resistor from VDDIO. |
| T1 | XTALI | 24 MHz crystal input - primary clock source for PLL and system clocks; requires matched trace length and load capacitance. |
| U1 | RTC_XTALI | 32.768 kHz crystal input - powers RTC and alarm in deep-sleep modes; draws <51 µA with RTC enabled. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX283CVM4B | Includes LCDIF and touchscreen controller; same CPU, memory, and connectivity features. | Required for direct RGB/TFT panel driving without external display controller. | Select MCIMX283CVM4B only if native LCD interface and 4/5-wire touch support are mandatory; otherwise MCIMX280CVM4B offers lower cost and identical processing/peripheral capability. |

FAQ
What is the maximum operating frequency of the MCIMX280CVM4B?
The MCIMX280CVM4B operates at a maximum CPU frequency of 454 MHz using the ARM926EJ-S core. This speed is achievable under specified DC operating conditions - notably VDDD ≥ 1.35 V and ambient temperature within the –40°C to +85°C industrial range. Frequency scaling is controlled via the CLKCTRL module and PLL fractional dividers, allowing dynamic adjustment for power optimization.
Does the MCIMX280CVM4B support NAND Flash with hardware ECC?
Yes, the MCIMX280CVM4B supports NAND Flash with hardware-based error correction via its General-Purpose Media Interface (GPMI) and integrated BCH encoder/decoder. It delivers up to 20-bit ECC per 512-byte sector, enabling reliable boot and data storage on SLC/MLC NAND devices - a critical feature for industrial firmware resilience and long-term field deployment.
What power supply configurations does the MCIMX280CVM4B support?
The MCIMX280CVM4B supports direct Li-ion battery operation (3.1–4.242 V on BATT/DCDC_BATT pins) and 5 V external supply (4.75–5.25 V on VDD5V), with automatic switchover managed by the on-chip PMU. Its triple-output DC-DC converter generates VDDD, VDDA, and VDDIO rails, while linear regulators provide clean power for analog and I/O domains - eliminating need for external PMICs.
Is the MCIMX280CVM4B pin-compatible with other i.MX28 variants?
Yes, all i.MX28 variants - including MCIMX280CVM4B, MCIMX283CVM4B, and MCIMX286CVM4B - share the identical MAPBGA-289 package (14 × 14 mm, 0.8 mm pitch) and pinout. However, functional differences exist: MCIMX280CVM4B lacks LCDIF and S/PDIF blocks present in higher variants, meaning unused pins in those functions remain non-functional despite physical compatibility.
What security features are implemented in the MCIMX280CVM4B?
The MCIMX280CVM4B includes hardware-accelerated security features: 128-bit AES decryption for secure boot, SHA-1 and SHA256 hashing engines, High Assurance Boot (HAB4) for authenticated firmware loading, and a read-only unique ID for DRM.
