The TS-7700 provides a migration path from the TS-7500/TS-7550 offering a significant performance increase, and a larger FPGA. The TS-7700 is based on the Marvell Arm®-based PXA166 800MHz, or optionally a PXA168 1066MHz. The TS-7700 features 10/100 Ethernet, high speed USB hosts, and 2 MicroSD sockets. The TS-7700 features a software programmable Lattice XP2 8Klut FPGA which by default implements several of our controllers such as our high speed SD interface, XUARTs, and more. With 2 SD card sockets this board is able to utilize our DoubleStore technology which makes the system extremely reliable.

Hardware features include:

• Ethernet MAC and PHY
• 1 USB host and 1 USB OTG
• Up to 6 UARTs
• 2 MicroSD card sockets
• SD, SDHC, SDXC support up (21.5MB/s write, 20.5MB/s Read)*
• Robust DoubleStore Flash Storage
• CAN
• I2C
• I2S
• RTC**
• Temperature Sensor***
• Watchdog timer
• Hardware random number generator

*Dependent on the SD card used. Speeds tested with Sandisk Extreme cards.

**External baseboard coin cell battery required.

***1/16 of degree Celsius resolution (and 1 degree absolute accuracy).

The TS-7700 SOM boots a Linux 2.6.34 kernel out of the box from one or both MicroSD cards, as well as an initial ramdisk for a very fast boot and a Debian Wheezy distribution for extremely flexible software. The Linux choice is highly recommended and our products are totally integrated with the open-source vision. There is no proprietary source code in the kernel since all the hardware specific functionalities are handled by user-space utilities (such as sdctl, xuartctl, etc.). The Linux kernel includes driver support for on-board hardware, enabling quick time to market of end-users applications.

The Debian Wheezy environment provides a powerful, stable, and familiar software stack. Debian provides over 28,000 software packages precompiled for the ARMEL architecture. This includes many common interpreters such as Python, Mono (C#), Ruby, PHP, TCL, Perl, Java, and Bash. Debian also includes the GNU Compiler Collection which allows compiling C/C++ directly on the board.

The software image includes an initial ram filesystem which boots immediately after the kernel is loaded and can execute custom userspace code. This allows execution of custom code in under a half second from power on. The initial ramdisk features a minimalistic busybox build for a fast boot, but it is also capable of executing binaries in Debian

Software features include:

• Linux 2.6.34
• Full Debian Wheezy (7.0) distribution
• Opencore FPGA reloadable in software
• Flexible programming language support
• Source code examples available
