描述 Description

The Arm9™-based i.MX251 applications processor is for cost sensitive automotive applications.  TheArm926EJ-S™ CPU can run at speeds up to 400MHz giving enough headroom for entry level automotive applicationswhile minimizing power consumption. Integration of two USB PHYs, a 12-bit ADC, low cost DDR2, MMC/SD/SDIO, 10/100Ethernet with RMII, and on-chip SRAM reduces the Bill of Material (BOM) costs for price-sensitive applications.
Thei.MX251 has the ability to connect with many different peripherals like Wi-Fi through SDIO or USB and Bluetooth viaUART or SSI/I2S.  With Enhanced Serial Audio Interface (ESAI) and CAN connectivity the i.MX251 is a costeffective solution targeted for audio connectivity.
