Freescale Semiconductor has introduced its Flexis JM family of MCUs to help designers easily incorporate USB connectivity into a wide range of consumer and industrial applications including PC peripherals, data transfer devices, lighting control systems, test and measurement equipment, patient monitoring systems, and security and access control panels.

The Freescale Flexis JM family includes the 32bit MCF51JM128 (JM128) ColdFire MCUs and the 8bit MC9S08JM60 (JM60) devices. The JM60 and JM128 USB devices are software- and pin-compatible, enabling designers to migrate from 8bit designs to more complex application designs that require 32bit performance.

Key features of the Flexis JM family include a 50.33MHz V1 ColdFire core, 25.16MHz bus frequency, a 2.7-5.5V operating range, up to 128Kbyte flash memory, and up to 16Kbyte SRAM. The MCUs also incorporate an integrated hardware cryptographic acceleration unit (CAU), random number generator accelerator (RNGA), and low-voltage detection and a Computer Operating Properly (COP) module.

The 32bit JM128 devices also integrate a controller area network (CAN) module, which is suitable for linking industrial automation and control systems. They also include an integrated USB controller that supports USB 2.0 full-speed host, device and On-The-Go (OTG) configurations.

The Flexis JM MCUs are offered in 80-pin LQFP, 64-pin QFP, 44-pin LQFP and 64-pin LQFP packages. The operating temperature range is -40C to 105C.

Freescale offers two evaluation kits for the Flexis JM family. The DEMOJM demonstration kit features 8bit and 32bit Flexis JM daughter cards. The full-featured EVB51JM128 evaluation system for the JM128 devices allows developers to take advantage of the additional performance and integration offered by the 32bit 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, respectively.

Both development kits ship with a DVD featuring a Special Edition of CodeWarrior tool suite and complimentary USB stacks. Code examples, walkthroughs and application notes also are available.

The suggested resale price for 10,000-piece quantities of the 32bit JM128 MCUs starts at $3.65, and $2.90 for the 8bit JM60 devices.

Samples of the Flexis JM devices are available now. The 8bit Flexis JM60 devices are currently available in volume quantities. Volume production for the 32bit Flexis JM128 devices is planned for September.

Freescale is one of the exhibitors at the 13th IIC-China 2008.
