To supply a solid power supply interface, 10 Vcc pins and 14 GND pins are
to provide for instantaneous current requirements, common capacitive de-
tween these devices and the MC68030 be minimized to provide sufficiently
f a s t r e s p o n s e t i m e t o s a t i s f y m o m e n t a r y
provided. This allows two VCC and four GND pins to supply power for the
address bus and two VCC and four GND pins to supply the data bus; the
remaining VCC and GND pins are used by the internal logic and clock gen-
eration circuitry. Table 12-7 lists the VCC and GND pin assignments.
To reduce the amount of noise in the power supplied to the MC68030 and
coupling techniques should be observed. While there is no recommended
layout for this capacitive decoupling, it is essential that the inductance be-
the internal PAL flip flop.
