W65C265DB Developer Board
Figure 5-7 W65C265DB Developer Board
Features:
W65C265S 16-bit MCU, total access to all control lines, Memory Bus, Programmable I/O Bus, PC
Interface, 20 I/O lines, two oscillators, 32K SRAM, 32K EPROM, W65C22S Versatile Interface Adapter
VIA peripheral chip, on-board matrix, PLD for Memory map decoding and ASIC design.
The PLD chip is a XILINX XC9572 for changing the chip select and I/O functions if required. To change
the PLD chip to suit your own setup, you need XILINX Data Manager for the XC9572 CPLD chip. The
W65C265DB includes an on-board programming header for JTAG configuration. For more details refer
to the circuit diagram. The on-board W65C265S and the W65C22S devices have measurement points
for core power consumption. Power input is provided by an optional power board which plugs into the 10
pin power header.
An EPROM programmer or an EPROM emulator is required to use the board. WDC’s Software
Development System includes a W65C816S Assembler and Linker, W65C816S C-Compiler and
Optimizer, and W65C816S Simulator/Debugger. WDC’s PC IO daughter board can be used to connect
the Developer Board to the parallel port of a PC.
