OHO-Elektronik Modules
OHO-Elektronik programmable logic modules are ideal solutions at minimum cost and area for
- educational platforms
- development and rapid prototyping environments
- drop-in replacement for discontinued devices.
The standard-pitch (2.54 mm = 100 mil) standard-gap (15.24 mm = 600 mil) dual in-line package (DIL / DIP) make them particularly convenient to connect with: development board, prototyping boards, strip-boards, matrix-boards, plug-in boards.
OHO-Elektronik GODIL Series
The OHO-Elektronik GODIL (= good old DIL, DIL = dual in-line) series are programmable logic mini-modules based on Xilinx Spartan-3E FPGA; 3.3 V and 5.0 V tolerant, USB 2.0 capable. They are suitable as drop-in replacement for devices in 40 / 48 DIL packages (e.g. discontinued CPUs such as Z80, 6502, 8080).
Key features:
- Low cost
- Based on Xilinx Spartan-3E FPGA
- SPI Flash memory for configuration and operation
- Both 3.3 V and 5.0 V tolerant
- Recommended as drop-in replacement for discontinued devices in 2 to 48 DIL packages (e.g. CPUs such as Z80, 6502, 8080).
- Inputs are 5.5 V tolerant
- Outputs are 3.3 V und 5 V compliant
- Easy diagnosis via 9-pin header (attach oscilloscope or logic analyzer)
- Easy to reuse
- Professional design
- 100% compatible with Xilinx ISE software

OHO_DY1
The OHO_DY1 module is a small 23 mm x 23 mm (0.9” x 0.9”) 7-segment display unit for displaying 3 digits of hex numbers (12 bits) or arbitrary segment combinations including their associated decimal points. It is primarily intended for debugging or educational use. The modules can be stacked to extend the number of digits.
A VHDL core is available, to directly display hex numbers on up to 5 stacked OHO-DY1 modules. Alternatively the modules can be connected to any microcontroller or DSP using only 3 GPIOs.
GOPLCP (GOPxxx Low Cost Programmer)
The GOPLCP download JTAG adaptor programs CPLD and FPGA modules of the the GOPxxx family via PC parallel port. The adaptor is compatible to the Xilinx Parallel Cable III.
