Freescale enhances affordability of 8-bit USB control for consumer and industrial applications

Entry-level JS16 microcontrollers designed to reduce cost and speed time to market for wireless PC peripherals and other USB devices

(PresseBox) ( AUSTIN, Texas, )
Freescale Semiconductor continues to enhance the affordability of its USB microcontroller (MCU) portfolio with the introduction of the 8-bit MC9S08JS16 MCUs. The JS16 devices extend Freescale's entry-level universal serial bus (USB) portfolio with one of the industry's most cost-effective 8-bit solutions for USB control.

The JS16 MCUs feature a full-speed USB 2.0 controller and up to 16 KB of flash. The JS16 devices also offer several features for system protection, such as low voltage detection and a computer operating properly (COP) module. The JS16 devices are ideal for a wide range of consumer and industrial applications, such as PC peripherals, wireless keyboards and mouse receivers, wireless adapters, USB dongles, SD card readers, RS-232 to USB bridges, remote controls and uninterruptible power supplies.

JS16 MCUs are software-compatible with Freescale's JM16 family, providing a migration path to higher performing devices. The JS16 devices are supported by a USB-LITE Stack by CMX and USB-MINI Stack with HID and CDC classes. These complimentary stacks are available with source code. To help developers speed time to market, the JS16 devices are backed by a complimentary edition of CodeWarrior® Development Studio for Microcontrollers 6.2, which provides an integrated design environment that simplifies source-level debugging and embedded development.
