MCIMX27MOP4A - i.MX27 ARM926EJ-S MPU 400MHz 473-LFBGA | NXP
Référence : MCIMX27MOP4A ✗ Fin de vieMCIMX27MOP4A Présentation
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 473-LFBGA package exposes the full external memory and peripheral bus for high-bandwidth designs.
Key features include the ARM926EJ-S 32-bit RISC core with Jazelle Java acceleration, a 16 KB instruction cache and 16 KB data cache, an integrated LCD controller up to VGA resolution, a hardware video accelerator (VICP/VPU offload block), USB 2.0 high-speed OTG, three MMC/SD card interfaces, 10/100 Ethernet MAC, and a CMOS sensor interface for camera modules. The on-chip RAM size is documented at 45K x 8, and the part is ROMless, requiring boot from external NOR/NAND flash. Power management is handled by multiple clock and power domains with DVFS support.
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. This page consolidates distributor pricing, drop-in equivalents, and design considerations that are not all present on the manufacturer datasheet itself.

Applications typiques
MCIMX27MOP4A convient pour 7 applications: Portable Media Player, Industrial HMI Panel, IP Video Phone, Point-of-Sale Terminal, Digital Photo Frame, Medical Patient Monitor Display, Connected Edge Sensor Gateway.
Portable Media Player
The MCIMX27MOP4A suits portable media players because its ARM926EJ-S core runs at 400 MHz and integrates an LCD controller plus hardware video pipeline blocks, enabling smooth H.264/MPEG-4 decode for QVGA-to-VGA resolution. With USB 2.0 High-Speed OTG, the device can sync media libraries at 480 Mbps; the three MMC/SD interfaces let the OEM support SD card storage up to 32 GB. Compared to discrete host CPU plus separate video SoC designs, the integrated i.MX27 collapses the BOM, but the older 90 nm process draws more power than current i.MX6/i.MX8 parts. Place the BGA on a 6-layer board with controlled-impedance routing for the memory bus.
Recommandé
Industrial HMI Panel
For industrial HMI panels, the MCIMX27MOP4A delivers a Linux-capable platform with integrated TFT LCD controller, 10/100 Ethernet MAC, and a CMOS sensor interface, all in one MAPBGA-473 chip. The 400 MHz ARM926EJ-S plus dedicated DMA can refresh a 640x480 panel while simultaneously driving a touch-screen controller over SPI and an Ethernet fieldbus. Industrial users value the long-term NXP silicon longevity and mature mainline Linux BSP, even though the part is now NRND. Recommend a 4-layer PCB with separate analog/digital grounds and an external watchdog for factory-floor reliability.
Recommandé
IP Video Phone
IP video phones benefit from the MCIMX27MOP4A's combination of a 32-bit CPU, integrated LCD controller for the local display, USB 2.0 HS for camera input, and 10/100 Ethernet MAC for SIP/RTP streaming. The hardware video accelerator offloads H.263 baseline encode/decode so the 400 MHz ARM926EJ-S can concentrate on the audio stack and user-interface code. Compared with adding a separate video DSP, the i.MX27 lowers BOM cost but cannot match the per-Watt efficiency of newer i.MX6/i.MX8 devices. Use a shielded RJ45 jack and route the Ethernet differential pair with 100-ohm differential impedance.
Recommandé
Point-of-Sale Terminal
POS terminals use the MCIMX27MOP4A because it integrates USB OTG for PIN pads and barcode scanners, SD/MMC for offline transaction logging, Ethernet for IP backhaul, and a TFT LCD controller for the operator display - all in one MAPBGA-473 package. Linux support is mature and PCI PTS-compliant software stacks are widely deployed on the i.MX27. Power budget is helped by DVFS, but the 400 MHz core still draws 200-300 mW under typical loads, so plan thermal relief on the BGA. Consider a conformal coating for retail environments.
Recommandé
Digital Photo Frame
Digital photo frames leverage the MCIMX27MOP4A's integrated LCD controller (up to VGA), USB 2.0 HS for image ingest, and SD/MMC slot for storage, while the ARM926EJ-S core handles JPEG decode and slideshow transitions at 400 MHz. The CMOS sensor interface is unused in this application but remains available for SKU variants that add a webcam. Because the part is NRND, design teams should plan a migration path to the i.MX6 or i.MX8 family for new photo-frame programs to avoid end-of-life surprises.
Recommandé
Medical Patient Monitor Display
Patient monitor displays benefit from the MCIMX27MOP4A's deterministic ARM926EJ-S core, integrated LCD controller for clinical-grade TFT panels, and Ethernet MAC for HL7/networked monitoring. Many vendors certify the i.MX27 for IEC 60601-1 because the long silicon life simplifies risk-management files. The lack of an MMU-related virtualization layer simplifies safety verification. Use a medical-grade isolated power supply and adhere to creepage/clearance rules around the BGA's perimeter balls.
Recommandé
Connected Edge Sensor Gateway
Connected-edge gateways pair the MCIMX27MOP4A's 10/100 Ethernet MAC, USB 2.0 HS, and three MMC/SD slots with the ARM926EJ-S core running Linux to bridge industrial sensors to cloud backends. The integrated peripherals reduce the external component count, and the MAPBGA-473 package supports extended-temperature layouts for outdoor enclosures. Because the MPN is NRND, gateways intended for 10+ year deployments should qualify a current i.MX6UL or i.MX8M part instead.

Notes de conception
The MAPBGA-473 package dissipates a few hundred milliwatts at 400 MHz; with the 19x19 mm footprint the junction-to-ambient thermal resistance (theta_JA) is typically in the 20-30 C/W range on a 4-layer PCB. Provide a continuous ground plane under the BGA and stitch vias around the perimeter to spread heat. Estimated: at 0.5 W dissipation the junction rises roughly 10-15 C above ambient on a standard 4-layer board with no heatsink, so derate accordingly for sealed enclosures.
The 473-ball LFBGA uses a 0.8 mm pitch and requires microvia or fine-pitch fan-out. Use a 6-layer stack-up with dedicated power planes for the core and I/O rails; route all DDR/SDRAM signals on the top layers with matched length and 50 ohm single-ended impedance. Place decoupling capacitors (0.1 uF X7R plus 10 uF bulk) within 2 mm of every power ball to suppress switching noise on the core rail.
Because the i.MX27 is ROMless, the boot configuration pins (boot mode select, JTAG, reset) must be set correctly or the system will hang at power-up. Do not omit the external 32.768 kHz crystal for the RTC domain - many boot failures trace back to a missing or improperly loaded RTC reference. Always validate the i.MX27 BSP against your specific die revision (the MPN suffix encodes the temperature and speed grade) before locking firmware.
The MCIMX27MOP4A is flagged NRND by NXP, meaning it is not recommended for new designs. For new programs, qualify a current i.MX6, i.MX7, or i.MX8 family part instead - their BGA footprints differ, so plan a PCB respin. For existing programs, lock in long-term stock and document the procurement plan with distributors because NRND supply gradually tightens over 3-5 years.
