Catena 1640

Low-Speed USB Development Platform

The MCCI Catena®1640 gives peripheral firmware developers everything needed to prototype USB Low Speed peripheral firmware in Microsoft Visual C, while working on a Windows XP, Vista, or Windows 7 system

The Catena 1640 combines a 16-bit PC Card interface with a Microchip PIC 18F4550 Low-Speed USB Peripheral Microcontroller chip and a low-level driver for Windows XP, Vista, or Windows 7. This controller is I/O mapped through the Windows PCMCIA peripheral controller. The Catena 1640 allows developers to write register-level code that accesses the PIC 18F4550 just as it would in a target system. Code can then be recompiled and used unchanged on a target embedded system.

Catena 1640
The Catena is ideal for use in early prototyping and proof of concept. Development of device class drivers for evaluating low-speed device system architectural concepts before product hardware is available.

Software can be developed in a number of "operating system" environments:
  • MCCI USB DataPump® portable firmware environment and "os/w32" - this binding for the DataPump simulates in the Windows environment. Developed code can be recompiled and directly ported to development platforms such as the MCCI Wombat™1510 Arm-based USB platform.
  • MCCI USB DataPump environment combined with Enea's OSE Windows-based simulator. Code developed in this environment can directly port to OSE-based targets.
  • Custom environments -- readily supported through the DataPump OS abstraction layer.
Catena 1640
Code developed with the MCCI Catena runs as a Windows application, and is debugged using standard debugging tools, including the Visual Studio environment.

In addition to supporting Low-Speed USB peripheral development, the Catena can be used for developing embedded USB device firmware, plus device functionality for system expansion. Code developed with the MCCI USB DataPump can readily use the PIC 18F4550 to simulate silicon that is under development or not yet available. The silicon-independent DataPump architecture allows the underlying silicon to be replaced with no effect on the higher level firmware developed earlier in a project.

The Catena 1640 is packaged in the same manner as all the MCCI Catena PC Cards.
