identifies all signals for the five package types. The
following pages illustrate the individual pin diagrams, plus a
combination diagram showing which of the full set of signals
are available in the 128-, 100-, and 56-pin packages.
The signals on the left edge of the 56-pin package in
are common to all versions in the FX2LP family with
the noted differences between the CY7C68013A and the
CY7C68015A. Three modes are available in all package
versions: Port, GPIF master, and Slave FIFO. These modes
define the signals on the right edge of the diagram. The 8051
selects the interface mode using the IFCONFIG[1:0] register
bits. Port mode is the power-on default configuration.
The 100-pin package adds functionality to the 56-pin package
by adding these pins:
• PORTC or alternate GPIFADR[7:0] address signals
• PORTE or alternate GPIFADR[8] address signal and seven
additional 8051 signals
• Three GPIF Control signals
• Four GPIF Ready signals
• Nine 8051 signals (two USARTs, three timer inputs,
INT4,and INT5#)
• BKPT, RD#, WR#.
The 128-pin package adds the 8051 address and data buses
plus control signals. Note that two of the required signals, RD#
and WR#, are present in the 100-pin version. In the 100-pin
and 128-pin versions, an 8051 control bit can be set to pulse
the RD# and WR# pins when the 8051 reads from/writes to
PORTC. This feature is enabled by setting PORTCSTB bit in
CPUCS register.
