Hardware Tools


WDC’s 65xx microprocessor developer boards are reference designs for your Embedded System Development or System-on-Chip (SoC) Development for either the GDSII or Verilog RTL core usage. We provide a FREE, digital form of the boards in our PCB Design Kit. These kits may be downloaded and used to jump start a design that uses features of the Terbium/65xx technology. WDC also has developed Terbi for use with our IP for FPGA/PLD designs and ASIC Emulation. WDC's latest ViaUSB Interface board was developed to provide USB software development/debug features to boards using the a W65C22 VIA device.


FPGA Based ASIC and PLD Development Board - Terbi-ECP2Mulator or "Terbi" (5" x 4")
Terbi was designed as a hardware emulation platform for ASIC design and development with WDC’s 65xx Technology.

Features of Terbi-ECP2Mulator
  • Lattice ECP2M−50 FPGA with 48 kLUTs, 4147 kbit of Embedded Block RAM, 22 sysDSP™ blocks, 88 18x18 multipliers,10 PLLs, and 270 user I/O pins
  • Lattice MachXO™ with 640 LUTs and 6.1 Kbit of RAM
  • USB 2.0 connector and integrated ispDOWNLOAD® cable for JTAG programming the FPGA
  • Flywire connector for programming using an ispDOWNLOAD cable (available separately from Lattice)
  • USB 2.0 compatible host connectors for interfacing with WDC’s ProSDK Development Tools
  • SATA interface with two LVDS signal pairs for high-speed data transfer
  • Altera Santa Cruz compliant connectors (2 x 40) providing 46 lines of I/O Expansion
  • 100−pin “MESA” connector compliant with T&MT USB PHY Standards
  • 28−pin expansion header for I/O. Compatible with WDC’s Parallel IO Board
  • LCD connector for character displays, with contrast potentiometer
  • 38−pin MICTOR connector for high speed Logic Analyzer connection
  • 25 MHz oscillator with clock distribution buffer
  • 4−pin DIP half socket for user selected oscillator
  • One HEX Rotary Switch
  • Dual Character 7−segment Display
  • 8 Activity LEDs
  • 8 Test Points
  • 4 Pushbutton switches for debug and user input
  • Green LED to indicate the proper operation of the 3.3V and 2.5 V power supplies
  • Blue LED which shows the configuration status (“DONE”)
  • Red LED to signal that the FPGA can be configured (“INIT”)
  • Yellow LED indicating the FPGA PROGRAM# I/O is asserted (“PROGRAM#”)
  • Program key to initiate the configuration sequence of the FPGA from SPI Flash memory
  • Reset key
  • 5V power supply
  • Switching regulator for the generation of the 3.3V I/O voltage and the 1.2Vcore voltage
  • Robust power configuration with jumper selections to power board with either of the two USB ports or the DC input jack

65xx Software Development Interface Board - ViaUSB (2" x 1")
WDC's Edu/ProSDK tools now support a USB interface for downloading application code to the target. This interface was developed to work with the W65C22S VIA and our GPIO RTL IP. Terbi comes with a built in USB interface using the FTDI FT245R USB FIFO IC and WDC's GPIO IP Module. For WDC's chip based devloper boards and other boards using a W65C22 VIA chip, WDC has created the ViaUSB Interface board. The ViaUSB has a with a 28-pin connector that mates with WDC's developer boards and APATCO's EB50 Single Board Computer. A cable can be made to go from your system and the ViaUSB. The ViaUSB board provides both a development interface to the Edu/ProSDK software and the ability to power the system board from the USB 5V supply. A reference design document has been created to explain the functionality of the ViaUSB board and how to get up and running with it and the Edu/ProSDK.
