i.MX35 Family of Multimedia Applications Processors Automotive portfolio: i.MX351, i.MX355 and i.MX356

The i.MX353 and the i.MX357 multimedia applications processors represent the next generation of ARM11 products with the right performance and integration to address applications within the industrial and consumer markets for applications such as HMI and display controllers.

Unless otherwise specified, the material in this data sheet is applicable to both the i.MX353 and i.MX357 devices and referred to singularly throughout this document as i.MX35 or MCIMX35. The i.MX353 devices do not include a graphics processing unit (GPU). For information on i.MX35 devices for automotive applications, please refer to document number, MCIMX35SR2AEC.

The i.MX35 processor takes advantage of the ARM1136JF-S™ core running at 532 MHz that is boosted by a multi-level cache system and integrated features such as LCD controller,Ethernet, and graphics acceleration for creating rich user interfaces.

It provides low-power solutions for applications demanding high-performance multimedia and graphics.

Targeted for the automotive market the i.MX351 is based on an ARM11™ core running at 532 MHz with 90 nm technology. The performance of the i.MX351 is boosted by a multi–level cache system, and includes features such as Enhanced Serial Audio Interface (or ESAI) for multi-channel (5.1) audio, SPDIF I/O for compressed digital audio connectivity and an advanced sample rate converter (ASRC) for mixing digital content with different sampling frequencies. For automotive the i.MX351 connectivity options include 2-CAN modules, Media Local Bus (or MLB) to connect to MOST ‘INIC’ transceivers, Ethernet and the ability to connect to external wireless modules via USB or SDIO.
