8-bit MCUs target industrial connectivity with Full-speed USB

Responding to growing adoption of USB connectivity in industrial applications, Freescale Semiconductor has extended its family of USB-enabled 8-bit MCUs by adding a new low-cost variant.

The MC9S08JS16 features 12Mbit/s USB2.0-device functionality, and includes an integrated transceiver. In addition to enhanced functionality in the end application there is USB bootloader software available on-chip via a small amount of dedicated USB ROM. To aid development a free, standalone, easy-to-use USB stack is also available, which speeds development and reduces evaluation costs. This stack is shared with other USB-enabled MCUs in Freescale’s Controller Continuum, which further boosts flexibility and convenience for designers. Other MC9S08JS16 peripherals include a Real-Time Clock (RTC), a Computer Operating Properly (COP) module, and a two-channel, 16-bit timer.

The background-debug capability and onchip In-Circuit Emulation (ICE) with real-time bus capture also eliminate the need for expensive emulation tools by providing a single-wire debugging and emulation interface.

Example software code further assists rapid design, including functions such as a boot loader, mouse, bridge application, data logger, and a demonstration PC GUI. Developer support also includes reference designs, application notes and webcasts.
