The ARM926EJ-S™-based i.MX251 applications processor is for cost sensitive automotive applications. The ARM926EJ-S™ CPU can run at speeds up to 400MHz giving enough headroom for entry level automotive applications while minimizing power consumption. Integration of two USB PHYs, a 12-bit ADC, low cost DDR2, MMC/SD/SDIO, 10/100 Ethernet with RMII, and on-chip SRAM reduces the Bill of Material (BOM) costs for price-sensitive applications.
The i.MX251 has the ability to connect with many different peripherals like Wi-Fi through SDIO or USB and Bluetooth via UART or SSI/I2S. With Enhanced Serial Audio Interface (ESAI) and CAN connectivity the i.MX251 is a cost effective solution targeted for audio connectivity.
