Overview
●The S08JM family extends NXP’s entry-level USB portfolio with one of the industry’s most cost-effective USB control solutions. Featuring on-chip USB 2.0 full-speed device support, it provides a fast, economical and easy way to standardize serial communications in industrial and consumer applications. All MCUs in the S08JM family use the enhanced S08 core. Additionally, NXP® provides two complimentary USB software stacks to help designers simplify applications with USB functionality: USB-LITE Stack by CMX and the USB-MINI Stack by NXP.
