Orange Tree Technologies Press Release

Oxford, UK, 28th September 2006 - Orange Tree Technologies announces ZestSC2, a high performance FPGA board that can be used stand-alone or connected by USB to a host computer. The board is aimed at data acquisition, and stand-alone embedded processing and control applications such as image processing, radar, industrial, and test.

The substantial I/O capability of 200 I/O pins is arranged on four connectors. These are 0.1 inch headers for compatibility with the widest range of external systems. The I/O voltage of each connector is independently jumper selectable between 3.3V, 2.5V, and a user-settable voltage. Each connector also has power and ground pins to power a daughter card plugged into it for applications such as video in/out and ADC/DAC. One example of the use of the board is to acquire data from a data source and process the data for display or storage on another device connected to the board.

The FPGA is the Xilinx Spartan-3 XC3S2000 (2 million gates) or XC3S4000 (4 million gates). There are two models of the board, one with the XC3S2000 and one with the XC3S4000 and 8MB SRAM. Both models have 32MB SDRAM and 200 I/O pins.

Flash EEPROM on the board is for configuring the FPGA. The Flash can be programmed from the host via the FPGA with supplied utilities, or it can be programmed from JTAG. The FPGA can be configured from Flash, host USB, or JTAG.

ZestSC2 follows on from the success of the smaller ZestSC1 and adds more resources in every area. The host software and logic interfaces are a superset of the ZestSC1 making upgrading as easy as possible. Full software drivers and libraries for Windows, and logic core libraries, are supplied free with the board. Logic interfaces are provided for the USB controller, SDRAM and SRAM, and examples show how to use the board. ZestSC2 is a USB Plug-and-Play device so is very easy to set up.
