NXP Semiconductors MCIMX27VJP4A

Overview

MCIMX27VJP4A from NXP Semiconductors is a multimedia applications processor built around an ARM926EJ-S core operating at up to 400 MHz, featuring integrated MPEG-4/H.263/H.264 video codec hardware acceleration, 16 KB instruction and 16 KB data caches, and support for DDR, NAND Flash, and SDRAM memory interfaces. It targets portable media players, digital cameras, and wireless PDAs requiring low-power, high-performance embedded processing.

For engineers reviewing the MCIMX27VJP4A datasheet, MCIMX27VJP4A pinout, MCIMX27VJP4A application, or MCIMX27VJP4A equivalent, key selection criteria include its MAPBGA-404 package, –20°C to +85°C industrial temperature grade, ARM926EJ-S core with MMU, on-chip eMMA_lt video accelerator, and dual USB host + OTG controller architecture.

Technical Context

The MCIMX27VJP4A implements a Harvard-architected ARM926EJ-S core with separate 16 KB I/D caches, Memory Management Unit (MMU), and ETM9 debug support. Its AHB crossbar switch (MAX) enables concurrent access by six bus masters-including the CPU's I-AHB and D-AHB-to three slave domains: primary AHB (internal peripherals), and two secondary AHBs (external interfaces).

It integrates dedicated multimedia subsystems including LCDC/SLCDC display controllers, CSI for CMOS sensors, AUDMUX for flexible audio routing, and a hardware video codec supporting MPEG-4 SP, H.264 BP, and H.263 P3 encoding/decoding at up to D1 resolution (720×486 @ 30 FPS). Power management includes DPTC, clock gating, and multiple power domains.

Key Specifications

FAQ

What is the maximum supported DDR memory speed for MCIMX27VJP4A?

The MCIMX27VJP4A supports DDR SDRAM operation at up to 266 MHz (133 MHz clock with double-data-rate), enabling peak theoretical bandwidth of 2.1 GB/s. This speed is validated in the electrical characteristics section (Section 4.2) of the MCIMX27EC datasheet Rev. 2, and requires strict PCB layout adherence to JEDEC DDR timing and termination guidelines to maintain signal integrity.

Does MCIMX27VJP4A include a hardware JPEG encoder?

No, the MCIMX27VJP4A does not integrate a dedicated hardware JPEG encoder. Image compression must be performed in software on the ARM926EJ-S core or offloaded to an external co-processor. The device does include the eMMA_lt accelerator for YUV/RGB conversion and scaling, which can reduce JPEG encode CPU load, but full JPEG encoding (Huffman, quantization, etc.) remains a software function per the i.MX27 functional description (Section 2.3.11).

Can MCIMX27VJP4A boot directly from NAND Flash?

Yes, MCIMX27VJP4A supports NAND Flash boot via its integrated NAND Flash Controller (NFC) with hardware ECC. When BOOT_MODE[1:0] = 0b10, the internal ROM bootloader initializes the NFC, reads the first 4 KB from NAND, and executes the boot image - enabling robust, field-upgradable firmware storage without requiring external SPI NOR or parallel NOR Flash.

What USB transceiver types are compatible with MCIMX27VJP4A's USBOTG port?

The MCIMX27VJP4A USBOTG port supports HS/FS/LS operation in host mode and HS/FS in device mode, and is compatible with ULPI (UTMI+ Low-Pin Count) transceivers, legacy full-speed transceivers, and transceiverless (on-die) PHY implementations. The USBOTG controller includes integrated analog circuitry for LS/FS line biasing, eliminating the need for external resistors in basic configurations per Section 2.3.36 of the datasheet.

Is the ARM926EJ-S core in MCIMX27VJP4A cache-coherent with DMA transfers?

No, the MCIMX27VJP4A's ARM926EJ-S core lacks hardware cache coherency for DMA. Software must explicitly manage cache maintenance (e.g., clean/invalidate D-cache lines) before and after DMA transfers involving cached memory regions. This requirement is documented in the i.MX27 Reference Manual and enforced by the DMAC's lack of snoop interface to the AHB fabric.
