Product details
Overview
MCIMX27LMJP4A from NXP Semiconductors is a multimedia applications processor built around the ARM926EJ-S core, operating at up to 400 MHz with 16 KB instruction and 16 KB data caches, integrated eMMA_lt video acceleration, and support for DDR, NAND Flash, and SDHC interfaces. It targets portable media players, digital cameras, and wireless PDAs requiring low-power, high-performance embedded processing.
For engineers reviewing the MCIMX27LMJP4A datasheet, MCIMX27LMJP4A pinout, MCIMX27LMJP4A application, or MCIMX27LMJP4A equivalent, key selection criteria include its –40°C to +85°C industrial temperature grade, MAPBGA-473 (Case 1931-04) package, absence of ATA-6 and VPU hardware blocks (vs. i.MX27), and confirmed support for H.264/MPEG-4/H.263 decode-only video acceleration.
Technical Context
The MCIMX27LMJP4A implements an ARM926EJ-S core with MMU, JTAG/ETM9 debug, and dual AHB buses connected via a 6×3 crossbar switch (MAX). Its memory subsystem includes 45 KB on-chip VRAM and 24 KB boot ROM, enabling fast boot and reduced external memory access.
It integrates dedicated multimedia peripherals: LCDC/SLCDC for display control, CSI for CMOS sensor input, AUDMUX for flexible audio routing, and three CSPI/SDHC controllers. Unlike the full i.MX27, it omits ATA-6, Memory Stick Pro, VPU encoder/decoder, and eMMA PrP/CSC functions-making it a cost-optimized variant for decode-centric applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | ARM926EJ-S 32-bit RISC CPU with Thumb support, MMU, and Harvard cache architecture |
| Clock Speed | Up to 400 MHz - enables real-time D1 (720×486 @30 FPS) video decode in supported codecs |
| Memory Interface | 266-MHz DDR, NAND Flash, NOR Flash, SDRAM, SRAM - supports multi-chip boot and runtime flexibility |
| Video Acceleration | eMMA_lt only (no VPU) - provides PrP/PP for scaling, color space conversion, but no hardware encode |
| Package | MAPBGA-473 (19 mm × 19 mm, Case 1931-04) - industrial-grade, lead-free, surface-mount compatible |
| Temperature Range | –40°C to +85°C - qualified for extended industrial environments without derating |

Pinout & Package
MCIMX27LMJP4A is housed in a 19 mm × 19 mm MAPBGA-473 package (NXP Case 1931-04), with 473 I/O balls arranged in a 25×25 array including power, ground, and signal balls. Pin assignments are defined per NXP Document MCIMX27EC Rev. 2, Section 5.4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_ARM | Core Power Supply | 1.2 V ±3% supply for ARM926EJ-S core - requires low-noise regulation and local decoupling |
| VDD_IO | I/O Power Supply | 3.3 V or 1.8 V selectable supply for all digital I/O banks - enables mixed-voltage interface design |
| CLKIN | Primary Clock Input | 24 MHz crystal or oscillator reference - feeds PLLs to generate system clocks including 400 MHz core clock |
| nRESET | Active-Low Reset Input | Synchronous reset assertion required for reliable boot sequence - must be held low ≥100 µs after power stabilization |
| BOOT_MODE[1:0] | Boot Configuration Pins | Strapped at power-up to select boot source (e.g., NAND, NOR, SDHC) - determines initial execution address and peripheral initialization |
Key Features
| Feature | Design Value |
|---|---|
| ARM926EJ-S Core with MMU | Enables full Linux, Windows CE, and Symbian OS deployment - essential for multitasking GUI-based devices |
| eMMA_lt Video Accelerator | Hardware-accelerated scaling, resizing, and YUV/RGB color space conversion - offloads CPU for efficient viewfinder and preview rendering |
| Triple SDHC Controllers | Supports simultaneous MMC/SD/SDIO card operation - enables dual-storage redundancy or host-peripheral coexistence (e.g., SD card + WiFi module) |
| Dual USB Host + OTG | USBOTG HS/FS/LS host mode and FS device mode - allows direct connection to USB mass storage, HID, and peripherals without hub |
| CSI and LCDC/SLCDC | Direct CMOS sensor interface + dual display controllers - eliminates external bridge ICs for camera-to-display pipelines in portable devices |
Applications
| Portable Media Player | Digital Camera |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multimedia applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX27MOP4A | Same ARM926EJ-S core, identical package (MAPBGA-473), but includes ATA-6 HDD interface and full VPU (encode+decode) | Supports hard disk-based DVRs and video editing - not suitable where MCIMX27LMJP4A's lower cost and smaller die are critical | Select when hardware encode capability and IDE storage are required; avoid if only decode and SD/NAND are needed |
| i.MX233 (MCIMX233CJM4A) | ARM926EJ-S core at 454 MHz, newer 45 nm process, integrated PMIC, but lacks eMMA_lt and has single SDHC | Targets ultra-low-power always-on devices (e.g., smart remotes); no hardware video acceleration - relies on software decode | Choose for lowest active power (<150 mW core) and integrated power management; not viable for D1 video decode workloads |
Compared with MCIMX27LMJP4A, MCIMX27MOP4A adds ATA-6 and VPU encode but increases cost and power; i.MX233 trades video acceleration for lower static power and integrated PMIC, making it unsuitable for real-time decode applications.

FAQ
What is the maximum video resolution and frame rate supported by MCIMX27LMJP4A?
The MCIMX27LMJP4A supports D1 resolution (720 × 486) at up to 30 FPS for H.264, MPEG-4, and H.263 decode using its eMMA_lt accelerator. It does not support hardware encoding, and performance is limited to decode-only operation per documented video codec specifications in the MCIMX27EC datasheet Rev. 2.
Does MCIMX27LMJP4A support boot from NAND Flash?
Yes, MCIMX27LMJP4A supports NAND Flash boot via its integrated NAND Flash Controller (NFC). Boot mode is selected using BOOT_MODE[1:0] pins, and the device executes internal ROM code to load firmware from NAND into internal SRAM before transferring control - confirmed in Section 3.1 and Table 2 of the MCIMX27EC datasheet.
Is MCIMX27LMJP4A pin-compatible with MCIMX27MOP4A?
Yes, MCIMX27LMJP4A and MCIMX27MOP4A share identical MAPBGA-473 packaging (Case 1931-04) and fully compatible pinout - both follow the same ball map defined in Section 5.4 of the MCIMX27EC datasheet, enabling PCB reuse between industrial and enhanced-feature variants.
What security features are implemented in MCIMX27LMJP4A?
MCIMX27LMJP4A includes SAHARA2 for symmetric/asymmetric crypto acceleration, SCC for secure RAM and policy enforcement, RTIC for runtime integrity checking, and IIM for fuse-based identification - all documented in Table 2 and Section 2.3 of the MCIMX27EC datasheet as part of its Platform Independent Security Architecture (PISA).
Can MCIMX27LMJP4A drive a color TFT LCD directly?
Yes, MCIMX27LMJP4A integrates LCDC and SLCDC controllers supporting RGB, YUV, and CPU interfaces - enabling direct connection to color TFT panels up to XGA (1024×768) resolution with programmable timing, dithering, and alpha blending, as specified in Section 2.3.20 and 2.3.33 of the MCIMX27EC datasheet.
