8- and 32-bit compatible microcontrollers add USB functionality

The Flexis™ series provides compatibility between 8- and 32-bit microcontrollers, enabling designers to offer multiple performance levels of their products using a single hardware and board design. The JM family of Flexis microcontrollers adds flexible USB options to this format.

The 8-bit MC9S08JM features a full-speed USB device, providing a quick and easy way to standardise serial communications in industrial and consumer applications. The 32- bit JM128 microcontroller features USB On-The- Go (OTG), enabling USB host or USB device operation. All JM devices feature an integrated transceiver saving cost, time and board space by eliminating additional components.

The advanced feature set includes a rich suite of communications peripherals, a 12-bit ADC, analogue comparator, two independent timer modules, and a real-time clock. In addition to this base feature set, the 32-bit MCF51JM128 offers a cryptographic acceleration unit, and a CAN module, both of which are increasingly utilised in a variety of industrial applications.

The background debugging system and on-chip In-Circuit Emulation (ICE), with realtime bus capture capability, provides a singlewire debugging and emulation interface that eliminates the need for expensive emulation tools.

Freescale also offers a stand-alone, complimentary, easy-to-use USB stack that enables developers to get running in minutes. Backing this is a full support and training ecosystem of reference designs, application notes, software examples and web casts.
