Catena 1620

USB On-The-Go Firmware Development Platform

The MCCI Catena® 1620 gives USB On-The-Go (OTG) firmware developers everything needed to prototype OTG firmware in Microsoft Visual C, while working on a Windows XP, Vista, or Windows 7 system.

The Catena 1620 combines a 16-bit PC Card interface with ST-Ericsson ISP1362 OTG silicon and a low-level driver for Windows XP, Vista, or Windows 7. The 1620 allows developers to write register-level code that accesses the ISP1362 just as it would in a target system. Code can then be recompiled and used unchanged on a target embedded system.

The Catena is ideal for use in early prototyping and proof of concept, development of device class drivers for an embedded host stack, and for evaluating OTG system architectural concepts before product hardware is available.

Software can be developed in a number of “operating system” environments
  • The ST-Ericsson Flexistack embedded USB stack, targeted specifically at the ISP1362.
  • MCCI USB DataPump® portable firmware environment and "os/none" - this binding for the DataPump simulates a direct "on-the-iron" environment with no operating system. Code can be recompiled and directly ported to development platforms.

  • 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.
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 OTG development, the Catena can be used for developing embedded USB device firmware, embedded USB host stacks, or a combination (USB embedded host for embedded peripherals, plus OTG functionality for system expansion). MCCI® supplies five different cable adapters:
  • OTG Mini A/B (for OTG dual role device emulation)
  • Mini B (for OTG or standard USB device emulation)
  • OTG Mini A/B plus standard USB A receptacle (emulates OTG dual role device plus embedded USB host)
  • Mini B plus standard USB A receptacle (emulates USB device plus embedded USB host)
  • Dual A receptacle (emulates dual USB host).
Code developed with the MCCI USB DataPump can readily use the ISP1362 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.

Table 1. MCCI Catena 1620
USB Silicon ST-Ericsson ISP1362 USB On-The-Go adapter
Device Endpoints fifteen: default pipe, plus fourteen general purpose endpoints, each configurable for bulk, isochronous or interrupt operation and either IN or OUT direction
Maximum Packet Sizes Bulk: 8, 16, 32, 64 bytes; Interrupt: 1..64 bytes; Isoch: 1..1023 bytes; Control: 8, 16, 32, 64 bytes. Total configured device max packet sizes must be less than 2462 bytes, including double buffering.
Throughput Up to 8 Mbps.
Interrupts Two interrupts multiplexed onto a single host IRQ. All interrupt handling is performed by the Windows 32 application, with minimal kernel overhead
Register Alignment ISP1362 registers are aligned on 4-byte boundaries in I/O space; each register is replicated. This allows use of DWORD I/O for loading and unloading the data registers and FIFOs, if desired
Operating Modes OTG Dual Role; USB Device; Dual USB host; USB host + OTG dual role; USB host + USB device
Operating Mode Configuration Automatic, based on the cable adapter plugged in.
Miscellaneous Each Catena 1620 is assigned four Ethernet MAC addresses, using the MCCI OUI. Addresses are accessed by reading the PCMCIA Card Information Structure (CIS).
