Chapter 9: Configuration, Design Security, and Remote System Upgrades in the Cyclone III Device Family
Configuration Features
9–25
Single-Device AP Configuration
The following groups of interface pins are supported in Micron P30 and P33 flash
memories:
■ Control pins
■ Address pins
■ Data pins
Following are the control signals from the supported parallel flash memories:
■ CLK
■ active-low reset (RST#)
■ active-low chip enable (CE#)
■ active-low output enable (OE#)
■ active-low address valid (ADV#)
■ active-low write enable (WE#)
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.
The following are the control signals from the Cyclone III device to flash memory:
■ DCLK
■ nRESET
■ FLASH_nCE
■ nOE
■ nAVD
■ nWE
