Working Principle

The TE0887-02 has a multi-layer board with 1.6mm of PCB thickness. A FPGA and a CPLD is programmed via the 20MHz JTAG programmer. The FPGA is used to design high-level control functions, and the CPLD makes hardware simulations realizable. Two layers are used for the FPGA for configuring different design applications. It brings more flexibility for the design of complex control functions.

The other layer is dedicated to the CPLD, which is used to define the logic function depending on the application. Eight logic devices can be programmed by the CPLD to enable the design of low-level sequence functions. Programming steps include setting the pin-package as required and the subsequent setting of the internal architecture of each device.
