NXP Semiconductors MCIMX355AVM4BR2

Overview

MCIMX355AVM4BR2 from NXP Semiconductors (formerly Freescale) is an AEC-Q100 Grade 3 qualified automotive application processor based on the ARM1136JF-S core operating at 400 MHz. It integrates an Image Processing Unit (IPU), VFP11 co-processor, 128 KB L2 cache, and supports DDR2/SDRAM, NAND/NOR Flash, USB 2.0 OTG/host, dual CAN, Ethernet MAC, and OpenVG 1.1 graphics acceleration - deployed in infotainment head units requiring real-time video decode, navigation UI, and hands-free telephony.

For engineers reviewing the MCIMX355AVM4BR2 datasheet, MCIMX355AVM4BR2 pinout, MCIMX355AVM4BR2 application, or MCIMX355AVM4BR2 equivalent, key selection criteria include AEC-Q100 qualification, 400 MHz deterministic performance under –40 °C to +85 °C ambient, MAPBGA-400 (17 × 17 mm, 0.8 mm pitch) package compatibility, and verified support for QVGA decode/WVGA display pipelines in production automotive systems.

Technical Context

The MCIMX355AVM4BR2 implements a dual-domain architecture: the ARM1136JF-S Application Processor domain (with L1/L2 caches, VFP11, IPU, GPU2D) handles OS execution and multimedia rendering, while the SDMA-shared domain manages DMA transfers, peripheral arbitration (SPBA), and connectivity stacks including dual FlexCAN, FEC Ethernet, and eSDHCv2 controllers. Its clock system uses MPLL/PPLL with OSC24M and OSCAUDIO reference oscillators to sustain synchronized timing across audio/video subsystems.

Power management leverages clock gating, power gating, and well biasing to reduce subthreshold leakage by ~10× in its 90 nm process - enabling low-idle power states without compromising wake latency for CAN bus wakeup or RTC alarm events. All I/O pins comply with 3.3 V tolerant logic levels and support configurable slew rate and drive strength per IOMUX settings.

FAQ

What is the maximum operating temperature specification for MCIMX355AVM4BR2?

MCIMX355AVM4BR2 is AEC-Q100 Grade 3 qualified with a specified ambient operating temperature range of –40 °C to +85 °C. This rating applies to the full device functionality including ARM1136JF-S core execution, IPU video processing, and dual FlexCAN operation - verified under JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life testing.

Does MCIMX355AVM4BR2 support boot from NAND Flash memory?

Yes, MCIMX355AVM4BR2 supports boot from SLC/MLC NAND Flash via its integrated NAND Flash Controller (NANDFC) submodule within the External Memory Interface (EMI). The device includes ROM-based boot code that initializes NAND, performs ECC correction using BCH algorithm, and loads the first-stage bootloader - confirmed in Section 4.1 of the MCIMX35 Reference Manual Rev. 2.

Is MCIMX355AVM4BR2 pin-compatible with MCIMX355AVM5BR2?

Yes, MCIMX355AVM4BR2 and MCIMX355AVM5BR2 share identical MAPBGA-400 package dimensions, ball map (Table 94), and pin functions - both use silicon revision 2.0 and Case 5284 packaging. The only difference is maximum guaranteed clock frequency (400 MHz vs. 532 MHz); all electrical characteristics, thermal profiles, and I/O timing remain compatible per MCIMX35SR2AEC Rev. 10 datasheet.

What graphics standards does MCIMX355AVM4BR2 support?

MCIMX355AVM4BR2 supports OpenVG 1.1 via its integrated GPU2D module - enabling hardware-accelerated 2D vector graphics rendering for scalable UI elements. It does not support OpenGL ES or Vulkan. Video decode is limited to QVGA resolution; display output supports WVGA (800 × 480) via parallel RGB interface with up to 24-bit color depth.

Can MCIMX355AVM4BR2 interface directly with a 24.576 MHz audio crystal?

Yes, MCIMX355AVM4BR2 includes a dedicated OSCAUDIO oscillator circuit designed to accept a 24.576 MHz crystal - providing a stable reference for audio PLLs and ensuring precise sample rate generation for ESAI, SPDIF, and ASRC modules. This is documented in Section 2.5 (OSC AUDIO) of the MCIMX35 Applications Processors for Automotive Products datasheet Rev. 10.
