电子发烧友网工程师 发表于 2018-04-22 12:31:00

NXP公司的MAC57D5xx系列MCU是基于适合实时应用的ARM® Cortex®-M处理器,以及适合应用和人机接口的ARM® Cortex®-A处理器的多核架构解决方案,集成了2D图像加速器(GPU),平视显示器(HUD)硬件曲面引擎,双TFT显示器驱动,步进马达驱动和功能强大的I/O处理器,提供最前沿的性能和稳定性,支持两个WVGA分辨率显示屏,适用于仪表板以及显示管理.本文介绍了MAC57D5xx系列MCU主要特性,详细框图和评估板MAC57D5MB主要特性,主要元件分布图和电路图.
 

  The MAC57D5xx family is the next generation platform ofdevices specifically targeted to the instrument cluster marketusing single and dual high resolution displays.

  Leveraging the highly successful MPC56xxS product family, NXP is introducing a multi-core architecture powered by ARMCortex-M (for real time) and Cortex-A processors (for applications and HMI), coupled with 2D Graphics Accelerators(GPU), Head Up Display (HUD) Warping Engine, Dual TFT display drive, integrated Stepper Motor Drivers and a powerfulI/O processor, that will offer leading edge performance and scalability for cost-effective applications.

  Powered by ARMR CortexR -M and Cortex-A processors, coupled with 2D graphics accelerators, HUD warping engine,Dual TFT display drive, integrated Stepper Motor Controller and a powerful I/O processor, these products offer leadingperformance and scalability for cost-effective applications.

  The family supports up to 2 WVGA resolution displays, including one with in-line Head up Display (HUD) warpinghardware. Graphics content is generated using a powerful Viviane GPU supporting OpenVG1.1, and the 2D Animation andComposition Engine (2D-ACE), which significantly reduces memory footprint for content creation. Embedded memories include up to 4 MB Flash, 1 MB SRAM with ECC and up to 1.3 MB of graphics SRAM without ECC. Memory expansion isavailable through DDR2 and SDR DRAM interfaces while two flexible QuadSPI modules provide SDR and DDR serialFlash expansion. In response to the growing desire for security and safety, MAC57D5/4xx family integrates NXP’s latestSHE-compliant CSE2 engine and delivers support for ISO26262 ASIL-B functional safety compliance.
