Freescale Flexis JM Microcontroller Series

Freescale Semiconductor recently introduced its Flexis(tm) JM family of microcontrollers (MCUs) to help designers easily incorporate USB connectivity into a wide range of consumer and industrial applications. The Freescale Flexis JM family includes the new 32-bit MCF51JM128 (JM128) ColdFire® MCUs and the 8-bit MC9S08JM60 (JM60) devices The JM60 and JM128 USB devices are software- and pin-compatible, enabling designers to migrate quickly and easily from simple 8-bit designs to more complex application designs that require 32-bit performance. Samples of the Flexis JM devices are available now. The 8-bit Flexis JM60 devices are currently available in volume quantities. Volume production for the 32-bit Flexis JM128 devices is planned for September 2008. The suggested resale price (USD) for 10,000-piece quantities of the 32-bit JM128 MCUs starts at $3.65, and $2.90 for the 8-bit JM60 devices.

The 32-bit JM128 devices integrate a controller area network (CAN) module, which is ideal for linking industrial automation and control systems. For developers seeking 32-bit performance and flexible USB connectivity, the JM128 MCUs include an integrated USB controller that supports USB 2.0 full-speed host, device and On-The-Go (OTG) configurations.

The JM devices are supported by Freescale’s complimentary USB software, development boards, reference designs, application notes, training and more. This comprehensive ecosystem helps simplify development and reduces time to market for applications that require USB connectivity. To minimize designers’ development cost and time, Freescale offers a complimentary USB-Lite software stack from CMX that supports the integrated USB modules on the Flexis JM devices. Source code for the software stack is available to developers to enable customization. Rounding out the software solution, Freescale’s CodeWarrior® Development Studio for Microcontrollers provides an integrated design environment that helps accelerate and simplify application development.

Freescale offers two evaluation kits for the Flexis JM family to help ease the design process. The cost-effective DEMOJM demonstration kit features 8- and 32-bit Flexis JM daughter cards, enabling developers to experience true 8- to 32-bit compatibility. The full-featured EVB51JM128 evaluation system for the JM128 devices allows developers to take advantage of the additional performance and integration offered by the 32-bit solution. The DEMOJM demonstration kit and the EVB51JM128 evaluation system are planned to be available in March at suggested resale prices of $99 and $325 (USD), respectively. Both development kits ship with a DVD featuring a Special Edition of CodeWarrior tool suite and the complimentary USB stacks. Code examples, walkthroughs and application notes also are available to help developers become productive right out of the box.
