NXP Semiconductors MCIMX27VOP4AR2

Overview

MCIMX27VOP4AR2 from NXP Semiconductors is a multimedia applications processor based on the ARM926EJ-S core, operating at up to 400 MHz with 16 KB instruction and 16 KB data caches, integrated video codec (MPEG-4 SP/H.264 BP/H.263 P3), and dual Vt 90 nm process for low-power operation. It targets portable media players, digital cameras, and feature-rich cellular phones requiring D1-resolution video decode/encode at 30 FPS.

For engineers reviewing the MCIMX27VOP4AR2 datasheet, MCIMX27VOP4AR2 pinout, MCIMX27VOP4AR2 application, or MCIMX27VOP4AR2 equivalent, key selection considerations include its MAPBGA-404 package, -20°C to +85°C industrial temperature grade, ATA-6 host interface, eMMA_lt hardware accelerator, and support for DDR/SDRAM/NAND/NOR external memory interfaces.

Technical Context

The MCIMX27VOP4AR2 implements an ARM926EJ-S core with MMU, JTAG/ETM9 debug support, and Harvard cached architecture. Its AHB crossbar switch (MAX) enables concurrent access across six master ports-including I-AHB/D-AHB from the CPU and four alternate masters-while three AHB-Lite slave ports serve internal peripherals like FEC, LCDC, and USBOTG.

It integrates dedicated multimedia accelerators: a Video Codec supporting simultaneous encode/decode, eMMA_lt for pre/post-processing (scaling, CSC), CSI for CMOS sensor input, and LCDC/SLCDC for display output. Power management includes DPTC, clock gating, and multi-domain power control, enabling operation down to 0.9 V core voltage in low-power states.

FAQ

What is the maximum supported video resolution and frame rate for hardware-accelerated decode on MCIMX27VOP4AR2?

The MCIMX27VOP4AR2 supports hardware-accelerated decode of MPEG-4, H.264 BP, and H.263 video up to D1 resolution (720 × 486) at 30 frames per second. This capability is implemented entirely within the on-die Video Codec module and does not require ARM926EJ-S CPU cycles for pixel-level processing, enabling efficient battery usage in portable media players and digital cameras.

Does MCIMX27VOP4AR2 support booting directly from NAND Flash memory?

Yes, MCIMX27VOP4AR2 supports NAND Flash boot via its integrated NAND Flash Controller (NFC) with hardware ECC. When BOOT_MODE[1:0] pins are configured appropriately at reset, the internal ROM bootloader initializes the NFC, reads the first 4 KB from NAND, and executes the secondary bootloader-enabling reliable, cost-effective mass storage boot without external SPI NOR.

What external memory types and speeds are supported by MCIMX27VOP4AR2?

MCIMX27VOP4AR2 supports DDR SDRAM up to 266 MHz, SDRAM, NOR Flash, NAND Flash (with 1-bit or 4-bit ECC), and SRAM via WEIM. The ESDRAMC controller handles DDR timing parameters including CAS latency, tRCD, and tRP, while WEIM provides programmable timing for asynchronous peripherals such as FPGA glue logic or legacy parallel memories.

Is the ATA-6 interface on MCIMX27VOP4AR2 compatible with standard 2.5-inch IDE hard disk drives?

Yes, MCIMX27VOP4AR2's ATA-6 host controller complies fully with the ATA/ATAPI-6 specification and supports PIO modes 0–4, Multiword DMA modes 0–2, and Ultra DMA modes 0–5. It has been validated with standard 2.5-inch IDE HDDs and ATAPI CD-ROM drives, requiring only level-shifting and termination circuitry per the interface specification-not additional protocol translation.

How does the eMMA_lt module in MCIMX27VOP4AR2 improve video processing efficiency?

The eMMA_lt module in MCIMX27VOP4AR2 integrates a PreProcessor (PrP) and PostProcessor (PP) that perform hardware-accelerated scaling, color space conversion (RGB↔YUV), deblocking, and deringing. By handling these operations independently of the ARM926EJ-S core and main memory bus, it reduces DDR bandwidth consumption by up to 40% and lowers CPU utilization during video playback or camera preview.
