i.MX53xA处理器主要特性:
Features of the i.MX53xA processor include the following:
• Multilevel memory system—The multilevel memory system of the i.MX53xA is based on the L1 instruction and data caches, L2 cache, internal and external memory. The i.MX53xA supports many types of external memory devices, including DDR2, low voltage DDR2, LPDDR2, DDR3, NOR Flash, PSRAM, cellular RAM, NAND Flash (MLC and SLC), OneNAND™, and managed NAND including eMMC up to rev 4.4.
• Smart speed technology—The i.MX53xA device has power management throughout the IC that enables the rich suite of multimedia features and peripherals to consume minimum power in both active and various low power modes. Smart speed technology enables the designer to deliver a feature-rich product requiring levels of power far lower than industry expectations.
• Multimedia powerhouse—The multimedia performance of the i.MX53xA processor ARM core is boosted by a multilevel cache system, Neon (including advanced SIMD, 32-bit single-precision floating point support) and vector floating point coprocessors. The system is further enhanced by a multi-standard hardware video codec, autonomous image processing unit (IPU), and a programmable smart DMA (SDMA) controller.
• Powerful graphics acceleration— The i.MX53xA processors provide two independent, integrated graphics processing units: an OpenGL® ES 2.0 3D graphics accelerator (33 Mtri/s, 200 Mpix/s, and 800 Mpix/s z-plane performance) and an OpenVG™ 1.1 2D graphics accelerator (200 Mpix/s).
• Interface flexibility—The i.MX53xA processor supports connection to a variety of interfaces, including LCD controller for two displays and CMOS sensor interface, high-speed USB on-the-go with PHY, plus three high-speed USB hosts, multiple expansion card ports (high-speed MMC/SDIO host and others), 10/100 Ethernet controller, and a variety of other popular interfaces (PATA, UART, I2C, and I2S serial audio, among others).
• Automotive environment support—Includes interfaces such as two CAN ports, an MLB port, an ESAI audio interface, and an asynchronous sample rate converter for multichannel/multisource audio.
• Advanced security—The i.MX53xA processors deliver hardware-enabled security features that enable secure e-commerce, digital rights management (DRM), information encryption, secure boot, and secure software downloads. For detailed information about the i.MX53xA security features contact a Freescale representative.
The i.MX53xA application processor is a follow-on to the i.MX51xA, with improved performance, power efficiency, and multimedia capabilities.

This document is the Hardware Reference Manual for the i.MX53 Quick Start board based on the Freescale Semiconductor i.MX53 Applications Processor. This board is fully supported by Freescale Semiconductor. This Manual includes system setup and debugging, and provides detailed information on the overall design and usage of the i.MX53 Quick Start board from a Hardware Systems perspective.
The Quick Start Board is an i.MX535 platform designed to showcase many of the most commonly used features of the i.MX535 Applications Processor in a small, low cost package. The MCIMX53-START is an entry level development board and a near perfect subset of its larger sister board, the MCIMX53SMD, which is available as a full, near-form factor tablet. Developers can start working with code on the Quick Start board, and then port it over to the SMD Tablet if additional features are desired. This gives the developer the option of becoming familiar with the i.MX535 Applications Processor before investing a large amount or resources in more specific designs.
