The TS-4720 is a low profile, credit card sized TS-SOCKET macrocontroller module which features a Marvell Arm® based PXA166 800 MHz. The TS-4720 features a software programmable Lattice XP2 8K LUT FPGA which by default implements several of our controllers such as our high speed SD interface, XUARTs, and SPI controller, and more.

External devices can connect to the TS-4720 using Ethernet, USB host, I2C, SPI, UARTs, or GPIO. We also provide an external 16-bit bus that can be implemented over 21 DIO pins. The two 100 pin downward-facing general-purpose headers make it easy to interface the TS-4720 with a standard TS-Socket baseboard, a baseboard of your design, or contact us for more information on our design services.

Hardware features include:

• Dual Ethernet using onboard switch
• 1 USB host and 1 USB OTG
• Up to 6 UARTs
• 4 GB MLC eMMC flash storage, configurable to 2 GB SLC for added reliability
• 1 microSD card socket
• SD, SDHC, SDXC support up (21.5MB/s write, 20.5MB/s Read)*
• LCD output up to WUXGA
• Video acceleration up to D1 (TS-4720-800), or 720p (TS-4720-1066)
• FPGA touchscreen controller interface
• SPI
• CAN
• I2C
• I2S
• RTC**
• Up to 81 DIO/GPIO***
• Temperature Sensor****
• Watchdog timer
• Hardware random number generator

TS-SOCKET Description

TS-SOCKET is an embedded computer standard designed and controlled by embeddedTS. It defines both a form factor and a connection pin-out and is based on two 100-pin low-profile connectors, allowing secure connection between a TS macrocontroller (CPU board) and a baseboard. Please refer to the TS-SOCKET Standard and Embedded Macrocontrollers resource for more information.

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

**External baseboard coin cell battery required.

*** Depends on features used (I2C, I2S, SPI, UARTs, etc). If all features are used, 39 GPIO are still available.

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

The TS-4720 SOM boots a Linux 2.6.34 kernel out of the box from either the eMMC flash or microSD cards to 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 spictl, 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
