MCIMX351AVM4BR2

Microprocessors Overview

The MCIMX351AVM4BR2 is an automotive-grade application processor from the i.MX35 family, designed for infotainment and navigation systems. It features an ARM1136JF-S core operating at 400 MHz with a 128-Kbyte L2 cache and 128 Kbytes of internal SRAM. The device integrates essential interfaces including dual CAN, Ethernet MAC, USB 2.0 OTG, and SDIO/MMC controllers. It lacks the Image Processing Unit (IPU) and OpenVG GPU found in other variants. Qualified to AEC-Q100 Grade 3 standards, it supports ambient temperatures up to 85 °C.

Microprocessors Feature Summary

• Optimized for automotive infotainment and navigation applications
• Integrated ARM1136JF-S microprocessor core with VFP co-processor
• Supports compressed audio playback and hands-free telephony processing
• Includes dual CAN interfaces and Ethernet MAC for vehicle connectivity

Microprocessors Applications

• Automotive infotainment systems
• Vehicle navigation units
• Telematics control modules

Microprocessors Procurement Notes

Verify the specific suffix 'R2' against official documentation to confirm package or revision details. Confirm that the absence of IPU and GPU aligns with system requirements. Ensure compatibility with existing board layouts due to silicon revision differences. Check current availability status as automotive processors may have long-term supply constraints.

Microprocessors Selection Notes

Select this part when IPU and GPU acceleration are unnecessary to reduce cost. Suitable for applications requiring robust automotive connectivity like CAN and Ethernet. Compare against MCIMX355 or MCIMX356 if video processing or graphics acceleration is required. Verify pinout compatibility with previous designs using silicon revision 2.0.

Microprocessors Part Context

This component belongs to the i.MX35 family of automotive application processors. It shares the same ARM1136 core and general peripheral set as higher-end models but excludes multimedia accelerators. It is distinct from consumer i.MX series processors by its AEC-Q100 qualification and extended temperature range support.

Microprocessors Replacement Considerations

MCIMX351AVM5B offers the same functionality at 532 MHz. MCIMX355AVM4B includes additional IPU and memory interfaces. Note that silicon revision 2.1 parts use a different ball map and are not pin-compatible with revision 2.0.
