shows typical twin-chip alternatives to particular M68HC711 or M68L711 systems.
ADD THE PSD TO THE DESIGN
Migration from an M68HC711 single-chip system to an M68HC11/PSD system can be accomplished in one
of three ways.
1. By building a daughter board that plugs into the MCU socket on an existing printed circuit board. The
board includes the M68HC11, the PSD, and system clock generation circuitry. Including the clock
generator on the daughter board is important to minimize radiated EMI.
2. By placing an edge or row connector on an existing printed circuit board to allow access to a PSD
device on a daughter board. The minimum signals needed include the address/data lines and control
signals (R/W, E, AS, RESET). This requires changing the existing schematic.
3. By redesigning the existing printed circuit board to accommodate the PSD device.
