SECTION 5
SIGNAL DESCRIPTION
This section defines the MC68302 pinout. The input and output signals of the MC68302 are
organized into functional groups and are described in the following sections. The MC68302
is offered in a 132-pin (13 x 13) pin grid array (PGA), a 132-lead plastic quad flat package
(PQFP), and a 144-lead thin quad flat package (TQFP).
The MC68302 uses a standard M68000 bus for communication between both on-chip and
external peripherals. This bus is a single, continuous bus existing both on-chip and off-chip
the MC68302. Any access made internal to the device is visible externally. Any access
made external is visible internally. Thus, when the M68000 core accesses the dual-port
RAM, the bus signals are driven externally. Likewise, when an external device accesses an
area of external system memory, the chip-select logic can be used to generate the chip-se-
lect signal and DTACK.
