San Jose, CA - March 30, 2009 - CMX Systems, well-known designer of real-time operating systems, TCP/IP stacks, Flash File Systems and USB software announces that it has further expanded its USB Host and Device support with additional Class drivers plus support for several new processor families. CMX-USB™ Host, Device and OTG stacks, where appropriate, now add support for the NXP LPC28xx and LPC3XXX families and the Freescale 5225x family.

New options announced for CMX-USB Host stacks includes: Hub Class support for external USB Hubs, the CDC-OBEX Class driver, RNDIS Class support for remote networking and the CDC-ECM Class driver for embedded devices interfaced as a standard Ethernet NIC card. A CDC-ECM Class driver, RNDIS driver, and Audio support is announced for USB device applications.

CMX-USB is presently available for microcontrollers with integrated USB including: Atmel AT91SAM7 family, AT91SAM9 family; Freescale Flexis, ColdFire, iMX, STMP and Power Architecture Technology families; NXP LPC2XXX family; Luminary Micro's Stellaris family; STMicroelectronics' STR7, STR9 and STM32 families and Texas Instruments' TI55xx DSPs. External USB controllers including: ISP156X, ISP176X, ISP1161, ISP1181, ISP1183, ISP1362 and MAX3421 are supported also.

CMX-USB-Host stacks are designed for processors with both integrated USB host controllers and external USB host controllers. The CMX-USB-Host™ package is fully compatible with CMX's Host Class drivers for Mass Storage, CDC, HID, Audio, MIDI, FTDI and PrinterLite. CMX-USB Host Mass Storage is fully compatible with CMX-FFS-THIN™, CMX-FFS-FAT™, and CMX-FFS-SAFE-FAT™ File Systems.

CMX-USB-BS™ is a device stack and is supplied with a HID class implementation for supporting Human Interface Devices such as a keyboard, mouse or joystick. Add-on options include: a Flash Bootloader, a full USB Mass Storage Class with optimized drivers for accessing MMC/SD cards or other devices, a CDC class implementation for supporting standard communications ports, Media Transfer Class for portable media devices, Reliable File Interface Class and an Embedded Pipe for interfacing a USB device with a host application. The USB Mass Storage is compatible with CMX-FFS-THIN, CMX-FFS-FAT, and CMX-FFS-SAFE-FAT File Systems.

The CMX-USB suite also offers an optional OTG (On-The-Go) Module for applications which require dynamic switching between USB host and device functionality. The CMX-USB-OTG™ module is available for those processors which are equipped with an OTG controller, supporting HNP and SRP protocols.

CMX-FFS-FAT is a full-featured file system for products that require FAT12/16/32 compliant media support and provides support for Long filenames, Multiple Volumes, Media Error handling, Mix of Media and Check Disk. CMX-FFS-SAFE-FAT is the Fail Safe, PC compatible file system for embedded device developers whose products require FAT12/16/32 compliant media support as well as added protection against the loss of data caused by unanticipated resets. CMX-FFS-THIN is a scalable, reduced footprint file system designed for integration for designs with limited resources and includes FAT 12/16/32, Long file names, Media Error handling. Both versions are provided with drivers for Compact Flash (True IDE and Memory I/O), MMC/SD/DSHC (SPI S/W or H/W) and RAM. Flash Translation Layer options are available for NAND and Atmel DataFlash.

CMX-USB and File Systems can be run stand alone and can be integrated with CMX RTOSes and TCP/IP stacks.
