The NXP MCIMX253CJM4A is a 32-bit i.MX25 applications processor built around an ARM926EJ-S core running at 400 MHz, housed in a 400-ball MAPBGA package (17x17 mm). It targets cost-sensitive industrial and general embedded applications that require a balance of low power and high performance without sacrificing connectivity options. The device integrates 144 KB of internal RAM, supports external program memory, and exposes up to 128 GPIOs for peripheral expansion. An applications processor (AP) is a system-on-chip (SoC) optimized for running an operating system and rich user-facing applications, as opposed to a microcontroller (MCU) optimized for deterministic real-time control. The i.MX25 family sits in the processor hierarchy as: ARM9 applications processor -> i.MX25 family -> NXP i.MX multimedia processors -> 32-bit microprocessor -> semiconductor. Compared with a bare MCU, the i.MX253 adds a memory management unit (MMU), higher CPU frequency, and richer connectivity peripherals, making it suitable for running embedded Linux, Windows Embedded, or real-time operating systems. Key features include the ARM926EJ-S core with 16 KB instruction cache and 16 KB data cache, an integrated MMU for full OS support, and dual 10/100 Ethernet MACs for networked industrial designs. The chip incorporates USB 2.0 High-Speed OTG, two CAN controllers, three UARTs, two CSIs (CMOS sensor interfaces), and an LCD controller with up to 24-bit parallel RGB output for display integration. The wide industrial temperature range and robust peripheral mix simplify designs in HMI panels, factory automation controllers, and connected sensor hubs. Architecturally, the i.MX253 relies on a 32-bit AMBA AHB peripheral bus, hardware accelerators for vector floating-point emulation via VFP9-S, and a multi-level memory system that combines internal SRAM with external DDR2 or LPDDR memory. The Power Management Unit (PMU) supports four clock domains for granular power gating, allowing designers to power down unused peripherals and keep total active power below 1 W in many embedded workloads. The integrated security controller supports secure boot and AES/SHA hardware hashing, a notable feature for industrial gateways that must authenticate firmware updates. Typical applications include industrial human-machine interface (HMI) panels, factory automation controllers, smart energy and grid monitoring, point-of-sale (POS) terminals, and medical diagnostic instrument front-ends. The dual Ethernet ports and CAN controllers also support automotive telematics and fleet management devices that need simultaneous IP and legacy bus connectivity. In each scenario the MCIMX253CJM4A's 400 MHz ARM9 performance is sufficient for graphical LVDS/TFT panels while leaving headroom for control loops. When designing with this part, allocate PCB layer budget for the 400-ball BGA: at minimum a 4-layer stack-up with continuous ground and power planes is recommended to meet the DDR2 signal-integrity budget. Decoupling requires a 1uF capacitor per power pin (or pin pair) plus bulk 10uF-47uF tantalum capacitors near the regulator outputs; LPDDR/DDR2 reference-zener-resistor nets must follow IBIS-validated routing rules.

An ARM9 microprocessor (MPU) is a 32-bit RISC processor core that integrates memory management, instruction, and data caches plus a flexible peripheral set onto a single die; the i.MX25 family is NXP's long-lifecycle industrial-grade ARM926EJ-S line that sits within the broader i.MX applications processor taxonomy (i.MX25 -> i.MX applications processor -> applications MPU -> embedded processor -> semiconductor). This taxonomy makes the part suitable for engineers who need deterministic Linux or WinCE behavior without migrating to a Cortex-A class core. Key features include 400 MHz ARM926EJ-S core with 16 KB instruction cache and 16 KB data cache, integrated DDR/DDR2 memory controller supporting up to 1 GB, and a rich peripheral set covering dual 10/100 Ethernet MACs, USB 2.0 OTG with PHY, four UARTs, three SPI, two I2C, two I2S/AC97 audio ports, and a hardware cryptographic accelerator (MAX, SHA-1, TRNG). Display support is provided through an LCD controller capable of up to XGA resolution, while connectivity includes a 12-bit ADC and PWM for motor and lighting control. The device is fabricated in a low-leakage 90 nm CMOS process and operates across a -40C to +85C industrial temperature range. The 400-LFBGA package exposes both industrial buses and parallel memory interfaces, allowing mixed-voltage designs without external level shifters on most rails. Typical applications include industrial HMI panels, factory automation controllers, point-of-sale terminals, energy-meter gateways, and connectivity-enabled IoT edge nodes. Designers also deploy i.MX25 in medical point-of-care instruments and e-ink/e-paper signage where Linux support and long-term supply continuity matter more than raw MHz. When designing with this part, allocate area for a 4-layer PCB with continuous reference planes beneath the 400-ball grid to preserve DDR2 signal integrity and to keep via stubs below the package keep-out zone. Use NXP's MCIMX25 Linux BSP and DDR calibration script (i.MX25 TO1.1 reference design) before tape-out because DDR2 timing margins on LFBGA are tighter than on equivalent BGA parts from newer i.MX families.

The device is fabricated in a 90 nm CMOS process and uses a 1.3 V typical core supply with separate 3.3 V I/O rails, allowing direct interfacing to standard logic without external level shifters. Internal PLL generates the CPU clock from an external 24 MHz reference, and dynamic voltage frequency scaling (DVFS) lets designers trade performance for power. The LFBGA-400 substrate enables dense PCB escape but requires microvia or via-in-pad manufacturing techniques. Typical applications include human-machine interface (HMI) panels, industrial control terminals, point-of-sale (POS) terminals, medical patient monitoring, smart-grid energy meters, and connected printing/scanning equipment. The integrated 3.3 V I/O and dual Ethernet make it well-suited for factory automation controllers needing fieldbus connectivity without an external PHY stack. For new designs, NXP recommends the i.MX6 or i.MX7 families for software compatibility, but the i.MX25 retains a long-lived firmware ecosystem and remains supported for industrial customers requiring long-term availability and Linux/WinCE BSP continuity. When designing in this part, allocate at least four PCB layers with continuous ground planes beneath the BGA to control impedance and provide thermal dissipation.

An ARM926EJ-S based microprocessor is a 32-bit RISC application processor with an MMU, DSP extensions, and tightly coupled memory that runs a memory management unit capable of running full operating systems such as Linux, WinCE, or a real-time OS. Within the broader hierarchy, this places the i.MX25 in the application processor class of embedded microprocessors (MPU), sitting above microcontrollers (MCU) and below higher-performance Cortex-A application processors. NXP positions the i.MX25 line for low-power, cost-sensitive human-machine interface (HMI) and connected device designs. Key features of the MCIMX257CVM4 include a 400 MHz ARM926EJ-S core with 16 KB I-cache and 16 KB D-cache, a 400-ball LFBGA (17x17 mm) package, integrated LCD and image-processing peripherals, multiple connectivity options including USB and Ethernet MAC, and an industrial temperature grade. Compared with higher-tier i.MX applications processors, the i.MX25 trades peak CPU frequency for lower system BOM cost and lower active power. Architecturally, the i.MX25 combines the ARM926EJ-S core with a multi-layer bus matrix, an image-processing unit (IPU) for LCD driving, and a hardware encryption accelerator. The integrated peripherals remove the need for companion display or image controllers, simplifying board layout and shrinking BOM cost for terminal-style products. Typical applications include human-machine interface (HMI) panels, industrial control terminals, point-of-sale (POS) terminals, and connected consumer electronics that need an LCD controller and ARM117-class CPU performance at low power. The wide peripheral set also suits networked printers, smart-grid terminals, and remote sensor gateways. When designing with this device, pay close attention to power-rail sequencing and DDR/SDRAM signal integrity; the part requires a properly terminated memory bus for stable operation at 400 MHz. PCB designers should follow NXP's i.MX25 hardware development guide for stack-up and decoupling.

The NXP MCIMX257DJM4 is an ARM926EJ-S based i.MX25 multimedia applications processor (MAPBGA-400, 17x17 mm) running at up to 400 MHz with a 32-bit data path and targeting consumer and general industrial embedded applications. It delivers high-performance CPU operation together with on-chip peripherals for USB, Ethernet, display, and storage interfaces in a single BGA package. Key specifications include a 400 MHz ARM926EJ-S core, 400-LFBGA (17x17) package, 128 I/O lines, and external program memory support with on-chip RAM. The processor combines a small die-area ARM9 core with DDR2/LPDDR memory controllers and an integrated LCD controller, suitable for cost-sensitive HMI designs. The MCIMX257DJM4 belongs to the i.MX25 family of ARM9 microprocessors (MPUs), a category of 32-bit microprocessors in NXP's broader i.MX applications processor portfolio. As an MPU (microprocessor), it relies on external SDRAM/NOR/NAND flash for program storage, distinguishing it from MCUs which typically integrate non-volatile memory internally. MPUs of this class typically address systems requiring higher clock speeds, larger external memory address spaces, and richer peripheral integration than 8/16/16-bit MCUs offer, making them a mid-tier solution between basic microcontrollers and higher-end Cortex-A application processors. Architecturally, the device implements the ARM926EJ-S core with a 16 KB instruction cache and a 16 KB data cache, plus an MMU for full operating system support. An integrated image processing unit (IPU), enhanced audio and security blocks, and a 10/100 Ethernet MAC accelerate multimedia and connected industrial products. Typical applications include factory automation HMI panels, industrial control terminals, medical patient monitoring displays, point-of-sale terminals, and connected consumer devices. The wide peripheral set (USB, Ethernet, CAN, UART, SPI, I2C, I2S, LCD) means most system requirements are satisfied without companion controller ICs. When designing with this part, pay close attention to PCB power decoupling because the 400-LFBGA package concentrates high-frequency switching currents in a small area. Maintain a 4-layer PCB with a continuous ground plane beneath the BGA; thermal performance depends primarily on inner copper layers, since the package has limited top-side heat dissipation.

MCIMX257DJM4A557 - i.MX25 ARM926EJ-S MPU, 400MHz, 400-BGA | NXP Semiconductors

NXP Semiconductors (formerly Freescale Semiconductor) MCIMX257DJM4A557 is an i.MX25 family multimedia applications processor built around an ARM926EJ-S core, integrating a 32-bit RISC CPU running at up to 400 MHz, an MMU for Linux/WinCE, and a broad set of on-chip peripherals inside a 400-ball plastic BGA measuring 17 mm x 17 mm with 0.8 mm pitch. The device targets industrial HMI, factory automation, point-of-sale terminals, and general embedded markets that require deterministic interrupt handling and a rich connectivity mix (Ethernet, USB OTG, CAN, UART, I²C, SPI, I²S/AC97, PWM, and an integrated LCD controller up to VGA resolution). At the system level, a microprocessor IC (often called an MPU) is a highly integrated variant of a microcontroller that combines a CPU core, memory controllers, and application-specific peripherals on a single die. The i.MX25 sits in the hierarchy: ARM926EJ-S CPU -> i.MX applications processor family -> NXP Multimedia/Communications processors -> embedded MPU -> semiconductor IC. Distinguishing it from a microcontroller, an MPU typically relies on external SDRAM and flash, and the i.MX25 exposes EIM and SDRAM controllers for exactly this purpose. Key features of the MCIMX257DJM4A557 include ARM926EJ-S at up to 400 MHz, 16 KB I-cache and 16 KB D-cache, MMU, integrated LCD controller with touchscreen interface, 10/100 Ethernet MAC, USB 2.0 OTG with PHY, CAN 2.0B, three UARTs, two CSPI, two I²C, I²S/AC97 audio, SD/MMC, and up to six PWM channels. Voltage rails are organized into core, I/O, and PLL supplies, with the on-chip voltage regulator supporting core domains. Architecturally, the i.MX25 uses an ARM9TDMI-compatible core with a separate 16 KB instruction cache and 16 KB data cache, a write buffer, and a standard AMBA AHB/APB peripheral bus matrix. The integrated Image Processing Unit (IPU) supports LCD displays up to VGA (640x480), enabling HMI panels without an external graphics controller. Hardware accelerators for security (HAB/SCC) provide secure boot and cryptographic engine for protected content delivery. Typical applications for the MCIMX257DJM4A557 include industrial human-machine interface panels, point-of-sale terminals, factory automation controllers, building automation gateways, medical patient-monitoring HMIs, and portable data terminals. Designers choose this MPU for its long-term industrial temperature support, ARM ecosystem maturity, and the i.MX25 reference design footprint provided by NXP. When designing with the i.MX25, pay close attention to the power-up sequence: the I/O supply (typically 3.3 V) must be applied before or simultaneously with the core supply to avoid latch-up, and the reset signal must remain asserted until all clocks are stable. The BGA substrate also requires a 4-6 layer PCB with buried vias for the inner-ball breakouts and matched-impedance routing for the USB and Ethernet differential pairs.

It is a 32-bit ROMless microprocessor designed for portable multimedia devices, industrial HMI panels, and embedded Linux/Android applications. The device is part of the long-running i.MX family and is flagged NRND (Not Recommended for New Designs) on the NXP product page. A microprocessor (MPU) is an integrated circuit that contains the full CPU, cache, memory controller, and a wide range of peripherals on one die. The i.MX27 belongs to the application processor tier of the i.MX hierarchy: i.MX27 -> ARM9 multimedia processors -> i.MX applications processors -> NXP edge processors -> embedded processors. Compared with microcontroller units (MCUs), MPUs integrate an MMU and external memory bus, allowing rich operating systems such as Linux, Android, and Windows Embedded CE to run on them.

The architecture pairs the ARM926EJ-S core with an AHB/APB bus matrix and dedicated DMA engines, allowing simultaneous video encode/decode, display refresh, and network traffic without CPU intervention. The VFP coprocessor is not present on this part; floating-point is emulated in software. Compared to later i.MX applications processors, the i.MX27 lacks the Cortex-A class core and NEON engine, so it targets lower-cost and lower-power designs rather than high-end graphics workloads. Typical applications include portable media players, IP video phones, industrial control panels with TFT LCD, point-of-sale terminals, and medical patient-monitoring displays that need an HMI. The integrated LCD controller and CMOS sensor interface also make it a fit for digital photo frames, barcode scanners, and entry-level machine-vision cameras. Rich connectivity (USB, Ethernet, SD/MMC) suits connected-edge products that bridge to cloud backends. When designing with this part, choose external DDR or SDRAM carefully because the integrated memory controller sets the data-rate ceiling, and provide adequate bulk decoupling near the 473-ball BGA. Because the MPN is marked NRND, plan long-life procurement now and qualify a successor from the current i.MX6/i.MX8 family for new programs.

MCIMX286CVM4B - i.MX286 ARM926 MPU 454MHz Dual CAN MAPBGA-289

The NXP Semiconductors MCIMX286CVM4B is an i.MX286 applications processor built around the ARM926EJ-S core running at 454 MHz, packaged in a 289-ball MAPBGA (14x14 mm, 0.8 mm pitch). It belongs to the i.MX28 family of multimedia application processors targeting consumer and industrial embedded products with on-chip display, power management, networking and connectivity blocks that reduce total system cost. An applications processor is a system-on-chip that integrates a CPU core, memory controllers and a heterogeneous mix of peripherals (display controller, connectivity MACs/PHYs, audio CODEC interface, security engine) onto a single die, eliminating the discrete companion chips that older architectures required. i.MX28 sits in the multimedia processor category, between microcontrollers (no MMU, no display pipeline) and high-end application processors (Cortex-A class with GPU). Its ARM926EJ-S core uses the ARMv5TEJ instruction set with a Java byte-code extension, providing MMU, caches, and DSP-style instructions for signal processing. Key features include: 454 MHz ARM926EJ-S core, dual CAN controllers (the i.MX286's distinguishing feature over i.MX283), integrated LCD controller up to WVGA, 10/100 Ethernet MAC with HP Auto-MDIX, two USB 2.0 high-speed PHYs (host + device), hardware AES/SHA encryption engine, four PWM channels, I2S audio port, and a built-in DC-DC converter and LDO subsystem that powers the chip directly from a single 5 V supply. Memory interface supports 16-bit DDR2/LPDDR with hardware ECC. Architecturally, i.MX28 integrates the power tree on-die so a 5 V wall-adapter input can be reduced, sequenced and distributed without external regulators for the core, memory and I/O rails. This reduces PCB area and BOM cost versus designs that require three or four external switching regulators for the equivalent function. Typical applications include: industrial HMI panels for appliances and building automation, e-readers, single-board computers and gateways, point-of-sale terminals, and consumer multimedia devices that need an LCD panel and CAN connectivity. Dual CAN support makes the part particularly attractive for industrial CAN bus networks and automotive-style body controllers. When designing with this part, allocate a four-layer PCB minimum, follow NXP's BGA escape and decoupling guidelines, and budget 200 mA continuous + transient peaks at 5 V input. Use NXP's i.MX28 reference board schematics and the Linux BSP available from NXP's website to shorten firmware bring-up. This page consolidates NXP datasheet figures, distributor stock signals and same-package i.MX28 alternatives not bundled in any single source, giving procurement and engineering teams one place to validate second-source options.

MCIMX286DVM4B - i.MX28 ARM926EJ-S MPU 454MHz MAPBGA-289 | NXP

The NXP MCIMX286DVM4B is an i.MX28 family 32-bit applications microprocessor based on the ARM926EJ-S core, running up to 454 MHz and housed in a 289-ball MAPBGA (14x14 mm) package. The device integrates dual CAN controllers, 10/100 Ethernet MAC, USB 2.0 high-speed with PHY, and an LCD controller, providing a complete system-on-chip for cost-sensitive connected embedded products. The "CVM4B" device marking denotes the industrial temperature grade and lead-free / RoHS-compliant assembly. An applications microprocessor (AP) is a high-integration System-on-Chip (SoC) that combines a general-purpose CPU core with peripherals, memory interfaces, and connectivity IP. The i.MX28 belongs to the broader NXP i.MX applications-processor family, which spans ARM9 through ARM Cortex-A and Cortex-M cores. APs sit above microcontrollers (MCUs) in the integration hierarchy: they run full operating systems such as Linux, ThreadX, or Windows Embedded Compact, and they target human-machine interface (HMI), connectivity gateways, and consumer multimedia products. Key features of the MCIMX286DVM4B include: ARM926EJ-S core with 16 KB I-cache and 32 KB D-cache, 128 KB internal SRAM, hardware crypto accelerators (AES, SHA, DES), dual CAN 2.0B controllers, 10/100 Ethernet MAC with HP Auto-MDIX, USB 2.0 HS OTG + USB 2.0 FS host with integrated PHYs, and an integrated LCD controller supporting up to WVGA resolution. The integrated power management unit (PMU) with on-chip regulators and battery charger enables battery-powered designs without external PMICs. The i.MX28 builds on the ARM926EJ-S Harvard architecture with a memory management unit (MMU) that supports virtual memory and protected operating systems. On-chip crypto accelerators offload AES/SHA/DES/RNG from the CPU, enabling secure boot and IPsec/SSL/TLS acceleration. The integrated pixel-processing pipeline and LCD controller support direct connection of TFT panels without an external bridge chip, reducing BOM cost. Typical applications include industrial HMI panels for appliances and building automation, smart energy meters and grid gateways, automotive infotainment telematics, medical point-of-care devices, e-readers, and connected IoT edge nodes. The 454 MHz performance headroom plus Linux support make it suitable for products that need a graphical user interface alongside network protocol stacks. When designing with this device, allocate PCB space for the MAPBGA-289 land pattern with microvia-in-pad construction to meet the 0.65 mm ball pitch escape rules. The integrated PHYs require careful power-rail decoupling; consult the i.MX28 Hardware Development Guide for reference layout. Long-term product planning should account for the NXP NRND (Not Recommended for New Designs) lifecycle status noted on the official NXP product page. This page synthesizes distributor inventory, parametric comparisons against i.MX28 family siblings, lifecycle signals, and practical PCB layout guidance that go beyond the manufacturer datasheet.

NXP describes extensive peripheral integration covering display, connectivity, real-time control, security, and networking. These characteristics position the device for portable multimedia systems that combine a graphical interface with communication and control functions in one compact package. The MCIMX287CVM4B belongs to NXP's established i.MX28 applications-processor family. Its architecture combines general-purpose processing with multimedia and connectivity-oriented peripherals rather than implementing only a minimal real-time control function. The package is therefore substantially more complex than a small microcontroller package and requires careful PCB escape routing, power planning, decoupling, and software support. Typical uses include portable human-interface devices, color-display terminals, connected consumer products, and embedded multimedia equipment. NXP markets the part as suitable for portable devices with rich user interfaces, while the integrated networking, security, and real-time-control blocks support connected product designs. Its 14 x 14 mm MAPBGA package also makes fine-pitch layout, via-in-pad considerations, and assembly-process planning important. When designing a new board, engineers should follow the NXP reference design, supported power supplies, memory topology, and pin-multiplexing guidance rather than treating the processor as a generic 32-bit IC. The product is marked NRND, so production continuity, last-time-buy conditions, or an approved migration path should be confirmed with NXP before committing new designs. This page combines verified distributor identification, manufacturer positioning, lifecycle status, sourcing information, and practical engineering context. It is intended to complement the official datasheet and reference materials rather than replace them.
