Configuration Features

Altera Corporation
The AP configuration scheme in Cyclone III devices supports flash speed grades of
40 MHz and above. However, the AP configuration for all these speed grades must be
capped at 40 MHz. The advantage of faster speed grades is realized when your design
in the Cyclone III device accesses flash memory in user mode.
For more information about the operation of the Numonyx StrataFlash Embedded
Memory P30 and P33 flash memories, search for the keyword “P30” or “P33” on the
Numonyx website (www.numonyx.com) to obtain the P30 or P33 family data sheet.
Single-Device AP Configuration
The following groups of interface pins are supported in Numonyx P30 and P33 flash
memories:

The supported parallel flash memories output a control signal (WAIT) to Cyclone III
devices to indicate when synchronous data is ready on the data bus. Cyclone III
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 III device and the flash memory.
