Product details
Overview
MCIMX355AVM5B from NXP Semiconductors (formerly Freescale) is an AEC-Q100 Grade 3 qualified 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) and OpenVG 1.1 GPU. It targets infotainment head units requiring QVGA video decode, WVGA display, Bluetooth hands-free audio processing, and map navigation.
For engineers reviewing the MCIMX355AVM5B datasheet, MCIMX355AVM5B pinout, MCIMX355AVM5B application, or MCIMX355AVM5B equivalent, key selection criteria include its 532 MHz CPU frequency, dual CAN 2.0B interfaces, 32-bit mobile DDR/DDR2/SDRAM support up to 133 MHz, 2× SDIO/MMC controllers, and automotive-grade thermal rating (–40 °C to +85 °C).
Technical Context
The MCIMX355AVM5B implements a hierarchical memory architecture with L1/L2 caches and a smart DMA engine (SDMA), enabling efficient offloading of image scaling, color space conversion, and graphics overlay from the ARM11 core. Its AP domain integrates VFP11 for floating-point acceleration in 3D graphics and audio algorithms.
Power management leverages clock gating, power gating, and well biasing to reduce subthreshold leakage by ~10× in the 90-nm process; supply voltage for internal logic is reduced to 1.22 V. The device supports multiple low-power modes (WAIT/STOP) managed via the Clock Control Module (CCM) and includes dedicated peripherals for automotive connectivity: dual FlexCAN, MLB, ASRC, ESAI, and SPDIF.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX356AVM5B | Includes PATA interface and CE-ATA support; otherwise identical CPU/cache/peripheral set. | Required for legacy IDE hard drive integration in premium head units; not needed for eMMC/SD-only designs. | Select MCIMX356AVM5B only if ATA storage interface is mandatory; MCIMX355AVM5B reduces BOM cost and layout complexity. |
| MCIMX355AJQ5C | Same silicon revision 2.1 with different ball map (Table 95/97); 532 MHz speed grade, same AEC-Q100 Grade 3 rating. | Requires PCB redesign due to incompatible pinout vs. MCIMX355AVM5B (silicon rev 2.0); no functional difference. | Choose MCIMX355AJQ5C only when migrating to newer silicon revision for long-term supply; avoid mixing revisions in same design. |
Compared with MCIMX356AVM5B, MCIMX355AVM5B removes redundant PATA/CE-ATA logic to lower power and cost for SD/eMMC-centric infotainment; compared with MCIMX355AJQ5C, it uses silicon revision 2.0's proven ball map-enabling drop-in replacement in existing layouts without re-spinning PCBs.

FAQ
What is the maximum operating frequency of the MCIMX355AVM5B?
The MCIMX355AVM5B operates at a guaranteed maximum frequency of 532 MHz, meeting all electrical specifications defined for the 400 MHz variant. This higher clock rate enables improved UI responsiveness and faster map rendering in automotive navigation applications without requiring board-level changes.
Does the MCIMX355AVM5B support OpenVG graphics acceleration?
Yes, the MCIMX355AVM5B includes an OpenVG 1.1-compliant GPU for 2D vector graphics acceleration. This capability is confirmed in the i.MX35 family documentation and enables smooth rendering of scalable UI elements such as maps, icons, and animated menus in automotive infotainment systems.
What automotive interface standards does the MCIMX355AVM5B natively support?
The MCIMX355AVM5B natively supports FlexCAN 2.0B (dual channels), Media Local Bus (MLB), Asynchronous Sample Rate Converter (ASRC), Enhanced Serial Audio Interface (ESAI), and SPDIF. These interfaces are explicitly documented for the MCIMX355 variant in the MCIMX35SR2AEC datasheet and enable direct integration into vehicle networks and audio subsystems.
Is the MCIMX355AVM5B pin-compatible with other i.MX35 variants like MCIMX351AVM5B?
No, the MCIMX355AVM5B is not pin-compatible with MCIMX351AVM5B. While both use the same MAPBGA package, Table 2 in the datasheet confirms functional differences: MCIMX351 lacks IPU, GPU, PATA, and CE-ATA modules, resulting in distinct peripheral signal assignments and incompatible ball maps for those functions.
What is the thermal qualification of the MCIMX355AVM5B for automotive use?
The MCIMX355AVM5B is AEC-Q100 Grade 3 qualified, rated for ambient operating temperatures from –40 °C to +85 °C. This qualification is explicitly stated in Section 1 of the MCIMX35SR2AEC datasheet and validates its suitability for under-dash automotive environments without forced cooling.
