MCIMX255AJM4A中文资料i.MX25 32-bit MPU, ARM926EJ-S core, 400MHz, MAPBGA 400数据手册恩XP规格书

描述 Description

The i.MX255 applications processor is based on the fast, low power Arm926EJ-S™ CPU with advanced connectivityfor automotive infotainment and applications that leverage auto-grade products.
For customers requiringhigh resolution and high color display the i.MX255 connects directly to high-resolution displays (up to SVGA) athigh color depth (up to 18bpp) providing outstanding image quality. The addition of a Camera Interface (CMOS SensorInterface) allows for video input acceptance, enabling support for applications such as, back-up cameras.Integration of DDR2, on-chip SRAM, and analog components like USB PHY, 12-bit ADC, and a resistive touchscreencontroller reduces the Bill of Material (BOM) costs.
The need to connect too many different peripheralslike Wi-Fi via SDIO or USB, Bluetooth via UART or SSI/I2S, and external storage via CE-ATA or PATA is addressed inthe i.MX255 by supporting these interfaces and multiple other connectivity options, e.g. CAN, Smartcard Interface,10/100 Ethernet with RMII support, and Enhanced Serial Audio Interface (ESAI).
