By eliminating SDRAM & 1.8V LDO, embedding I2C/SPI/UART/USB2.0 FS Device, and employing SpiFlash for code storage/XIP/write-back, the N55UL501 stands out of the competition through its superb benchmarking @ cost/performance. The N55UL501 is suitable for numerous potential applications that would run a MIPS-hungry task beside the application control program. The solution is cost-effective from system BOM perspective, while the design flexibility allows for various derivatives to come next.
