S08JM: 8-bit USB Cost-Effective JM MCUs  Favorite

The S08JM family extends Freescale’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, Freescale 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 Freescale.
