NXP Semiconductors MCIMX355AJQ5CR2

Overview

MCIMX355AJQ5CR2 from NXP Semiconductors (formerly Freescale) is an AEC-Q100 Grade 3 automotive application processor based on the ARM1136JF-S core operating at 532 MHz, featuring 16 KB L1 instruction cache, 16 KB L1 data cache, 128 KB L2 cache, and integrated Image Processing Unit (IPU) for real-time video preprocessing and display control. It supports automotive infotainment systems requiring QVGA decode, WVGA display, and hands-free telephony with Bluetooth AEC/NS.

For engineers reviewing the MCIMX355AJQ5CR2 datasheet, MCIMX355AJQ5CR2 pinout, MCIMX355AJQ5CR2 application, or MCIMX355AJQ5CR2 equivalent, key selection criteria include its 532 MHz CPU frequency, dual CAN 2.0B interfaces, 2× SDIO/MMC controllers, OpenVG 1.1 GPU support, and AEC-Q100 qualification for ambient operation up to +85 °C in automotive environments.

Technical Context

The MCIMX355AJQ5CR2 implements a hierarchical memory architecture with L1/L2 caches and a smart DMA engine (SDMA), enabling efficient offloading of image processing, audio routing via AUDMUX, and asynchronous sample rate conversion (ASRC) for multi-source audio synchronization. Its ARM1136JF-S core includes VFP11 co-processor for floating-point acceleration and Jazelle technology for Java bytecode execution.

Power management integrates clock gating, power gating, and well biasing to reduce subthreshold leakage by ~10× in the 90 nm process, supporting multiple low-power modes (WAIT/STOP) while maintaining full peripheral accessibility via the CCM clock control module and IOMUX pin multiplexing.
