NXP Semiconductors MCIMX280DVM4B

Overview

MCIMX280DVM4B 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 support for DDR2/LV-DDR2/mDDR memory. It targets industrial HMI panels, handheld scanners, and portable medical devices requiring low-power, single-chip system integration.

For engineers reviewing the MCIMX280DVM4B datasheet, MCIMX280DVM4B pinout, MCIMX280DVM4B application, or MCIMX280DVM4B equivalent, key selection criteria include its –20°C to +70°C commercial temperature grade, MAPBGA-289 (14 × 14 mm, 0.8 mm pitch) package, absence of CAN and Ethernet switch, and fixed i.MX280 functional subset versus i.MX283/286/287 variants.

Technical Context

The MCIMX280DVM4B implements the ARM926EJ-S core with 16 KB instruction and 32 KB data caches, coupled to a unified AHB/AXI interconnect fabric supporting five AUARTs, four SSPs (SDIO/MMC/SPI), two I²C interfaces, and dual SAIF audio controllers. Its clock architecture uses a 24 MHz crystal input and PLL-based domain generation with fractional dividers for precise peripheral timing.

Power management is handled by an integrated PMU comprising a triple-output DC-DC converter, linear regulators, battery charger, and brownout detection across VDDD, VDDA, VDDIO, and VDD4P2 rails. The device supports secure boot via 128-bit AES decryption, SHA-1/SHA256 hashing, and HAB4, with 1280-bit OCOTP for key storage and device identity.

Key Specifications

Pinout & Package

MCIMX280DVM4B is housed in a plastic MAPBGA-289 package measuring 14 mm × 14 mm with 0.8 mm ball pitch. Ball assignments follow the i.MX280-specific map defined in Section 4.4 of IMX28CEC Rev. 4 (pages 63–64), including dedicated power domains (VDDD, VDDA, VDDIO), signal groups (AUART0–4, SSP0–3, USB_OTG/USB_HOST), and critical control pins (PSWITCH, RESETN, DEBUG).

FAQ

What is the maximum operating frequency of the MCIMX280DVM4B CPU core?

The MCIMX280DVM4B integrates an ARM926EJ-S core rated for operation up to 454 MHz under specified voltage and temperature conditions (VDDD ≥ 1.35 V, TA = –20°C to +70°C). This frequency is achieved using the internal PLL driven by the 24 MHz crystal input, with fractional dividers enabling precise clock domain generation for peripherals without requiring external clock generators.

Does the MCIMX280DVM4B support CAN bus communication?

No, the MCIMX280DVM4B does not include FlexCAN modules. As confirmed in Table 2 of the i.MX28 documentation, CAN functionality is absent in the i.MX280 variant and first appears in the i.MX286 and i.MX287 derivatives. Designs requiring CAN must use MCIMX286DVM4B or MCIMX287CVM4B instead, which provide two CAN 2.0B interfaces.

What memory types does the MCIMX280DVM4B support for external storage?

The MCIMX280DVM4B supports mobile DDR (mDDR), DDR2, and LV-DDR2 memory via its External Memory Interface (EMI), with clock frequencies up to 205 MHz under voltage overdrive conditions. It also supports SLC and MLC NAND Flash through the GPMI controller with configurable 20-bit BCH ECC, enabling robust firmware and data storage in industrial and medical applications.

How does the MCIMX280DVM4B handle power management for battery-powered operation?

The MCIMX280DVM4B integrates a comprehensive PMU with a triple-output DC-DC converter, linear regulators, Li-ion battery charger, and brownout detection across VDDD, VDDA, VDDIO, and VDD4P2 rails. It supports seamless switchover between battery and 5-V supply, programmable current limiting, and deep-sleep modes with <21 µA off-state current - enabling multi-week battery life in portable HMIs and meters.

Is the MCIMX280DVM4B pin-compatible with other i.MX28 variants like MCIMX283DVM4B?

No, the MCIMX280DVM4B is not pin-compatible with MCIMX283DVM4B or other i.MX28 variants despite sharing the same MAPBGA-289 package. Functional block differences - such as absence of LCDIF and touchscreen controller in MCIMX280DVM4B - result in distinct ball maps and signal assignments, requiring unique PCB layouts for each variant as documented in Sections 4.4–4.7 of IMX28CEC Rev. 4.
