Single-Device AP Configuration
The following groups of interface pins are supported in Numonyx P30 and P33 flash
memories:
■
■
■
The following control signals are from the supported parallel flash memories:

■
The supported parallel flash memories output a control signal (WAIT) to Cyclone IV E
devices to indicate when synchronous data is ready on the data bus. Cyclone IV E
devices have a 24-bit address bus connecting to the address bus (A[24:1]) of the
flash memory. A 16-bit bidirectional data bus (DATA[15..0]) provides data transfer
between the Cyclone IV E device and the flash memory.
The following control signals are from the Cyclone IV E device to flash memory:
